In-Between Posts

This is work I did between the shop nights of 2/14/13 and 2/21/13:

Because my notes are sketchy, I'll summarize by saying it looks like I spent the week talking to people whose advice I respect about the condition of this lightened flywheel and seeing if they had a lead on a 9" flywheel.

I ended up getting a used (good core, or possibly make-do condition) 9" pressure plate from my uncle, and my friend B thought he found the correct 9-1/2" pressure plate (1949-50 Lincoln? Truck?) to fit the pre-'49 throwout bearing snout.  I found a flywheel at SF Flatheads/So-Cal Speed Shop Sacramento that is drilled for 9", 10", and 11" and looks just like my 9-1/2", so it might be a viable option.

Lastly, I made an unsuccessful visit to a local industrial hardware supplier to see if they had any clevises I could use for the brake pedal arm to master cylinder linkage.  Alas, they did not (in fact, the first counter jockey didn't even know what a clevis is!) but the second parts man correctly recognized the part I had in my hand (the threaded rod with an eye at the end) as a brake/M/C rod (although he guessed VW or early Porsche.  I got to talking with him and discovered that he builds sprint cars, drag motors, and does car builds/restorations.  I made sure to get his name and number for possible future fabrication work with my original go-to guy is gone (retired, as I've heard).

Also, during this week (although it might've been later as I'm writing all of these several months after I took my working notes) I got from my uncle several brake rods (mechanical) and clevises to use for the brake and clutch linkages.

Valentine's Date?

I wasn't very consistent when I was drafting these posts.  I might've done this work on 2/14/13 and drafted this on 2/21/13 or I might've done the work on 2/21/13.  I know we worked Valentine's Day as my wife and I postponed our date to avoid the crowds and expense of the holiday.  Nonetheless, my notes are sketchy enough that it's a brief post.

It appears that this night we drilled out to 3/8" the mounting holes (I originally had 5/16") for the master cylinder (a '39 Ford-type) on the Tardel mounting bracket that I had made from the drawings in his (and Mike Bishop's) book.  Despite my wanting to purchase all original style Ford bolts from this supplier, W insists in the interest of cost and ease of assembly (coarse thread (UNC) being faster to start and tighten than SAE (fine thread)) that we just use hardware from the local hardware and big box stores.  And seeing how he has become our parts runner (going out and buying hardware for which I reimburse him), how can I argue with him?  The cost is a good factor, but I sure appreciate not futzing around with "just the right bolt" when we can have it assembled that night.

We also took a look at the 9" flywheel on my other flathead to discover, in W's words: "some damned hotrodder's lightened this thing!"


Not sure it will work, but I'm still coming up dry looking for a 9" flywheel elsewhere.

Early Ford V-8 Service Bulletins



This was meant to be essentially a notes post for myself, to record the tags/labels/whatever Blogger wants to call them now, that I'll begin tagging and, eventually, go back and retag my old posts for easier topical searches.

I have recorded below the categories or binder tabs found in early Ford V-8 Service Bulletins (also used in the Model A era, maybe Model T, too - I'm not sure.  In searching for a link for the previous sentence, I was surprised how little I found on this topic outside of eBay listings.  If you ever get a chance to see/borrow/scan/buy an original set of these service bulletins, do not pass up the chance!  The repros are great, and I have a couple of sets, but the originals are priceless because of their size, clarity, and the tactile feedback you get from the (cotton-based?) paper and history they ooze.

Anyway, the bulletins were issued to Ford mechanics to update/illustrate/educate them on running changes to Ford parts and services, including some of the new, gee-whiz things like hydraulic brakes and overdrive (Lincolns) and are invaluable nowadays to understand the how and why of Ford parts when most of the original old-timers are gone.

2/14/13: Valentine's Day Motor Work



Tonight we pulled the oil pan and flywheel.

To do this work, however, we first had to mount it on my engine stand.  This was not as easy as the first time I did it, however, because I was ignorant to one or two very important facts.  The first is that the front exhaust port bolt holes are not 3/8" like the middle and rear holes; the fronts are 7/16".  I didn't know this last time and somehow was lucky enough to shove some 3/8" bolts in there and not have them tear out of their threads and drop the motor on my feet.

My friend W (the old timer) said that this dimension difference dates back to the first V-8's and Ford carried it through (at least through '48; I'm not sure about '49-'53 blocks).

So, we had to run taps into all the bolt holes to clean them up and then drill out the Vern Tardel engine stand mount to accommodate the larger front bolts (that we had to scrounge from my assorted coffee cans filled with hardware).



Once we mounted the engine securely to the stand with a mixture of too long and just-right bolts and nuts, we pulled the oil pan and removed the flywheel and W examined the engine and the pan mounting job I did.  He is convinced that if the pan and its seals (front, back, side rails) are not installed just right, you're asking for leaks.

He thought the cork seal in the back was OK, but the pan flange could be centered better, so he pounded it straight.


In taking a quick look at the motor, (and I subsequently stuck a set of dividers down one of the bores), W thought that the previous rebuilder (this motor was rebuilt at some time) probably pulled the sleeves and rebored it .045 (my understanding) to get it to 239".  Therefore, it's probably an 81A, originally 221 cu. in., not a 99A or 99T Mercury or truck block.

As the apprentice mechanic on this job, I got the unenviable task of cleaning out the residue sludge (that had dripped out of the block since I last ran and drained it) out of the pan and filing and straightening the pan rails to ensure a good seal when we put it back on.

Next thing to do for me is search for a usable 9" flywheel and pressure plate.

Interstitial





OK,  I finally have a chance to start publishing some of the backlog of blog posts on the project progress.  Also, since it's been some time since I've regularly posted, I've picked up some ideas for tagging and references to people and information in my posts that will vary from previous posts.  I hope to eventually go back and retag the previous posts for easy indexing and reference in the future.

For now, you'll just start to see the old posts pop up, with the date of the work done in the title.

Working, Not Writing


OK (or, as my boy would say, o-hay!), whereas before my problem was writing but not working on the car, now my problem (a good problem to have) is working on the car, but not writing - well, not publishing.

Since my February 13 post, I began working every Thursday and, eventually, every Tuesday and Thursday on the hot rod.  Or, as my friend recently corrected me, "roadster," as it sounds much more classy than "hot rod."  Each night, following the work session, I've diligently jotted down in Blogger my notes from the evening and attached the photos.  Now I need to take some time to expand upon (or expound) on those notes and publish the posts.

So, this is a brief update as I hear son #2 crying now, but I hope to return here soon to publish the delinquent posts.

2/21/13: Pedaling Along



Tonight we (perhaps) finished drilling all of the 3/8" bolt holes to mount the master cylinder bracket to the frame, and the master cylinder to the bracket.  The bracket I have (that I built from plans in the Bishop/Tardel book) is designed to mount using (presumably) factory '32 pedal assembly and K-member holes.  Well, I'm using a '33-'34 pedal assembly and a Tardel K-member for the Model A frame, so we had to drill all but one of our mounting holes (by step drilling from 1/8" or so) and opened up to 3/8" the holes for the master cylinder (for strength).  This was tedious (a 64th or so at a time) and resulted in several broken bits (from my ancient set of no-name bits).  Several times, to keep us going, W repointed dull or not-so-badly broken bits on the bench grinder.

After doing that, we took a look at the swing for the clutch pedal and determined it will hit the firewall before full travel.  So, we marked the trouble spot (ended up being not just a notched-out section, but a short strip down the firewall) and cut horizontally at the top with the hack saw (just an aside, the hack saw is becoming one of our favorite go-to tools - it's fast, and quiet, which is great at 10 o'clock at night).  We then used vice grips and a small block of metal to clamp at the vertical cut line and just bent back and forth until we broke the section free.

Cut and bent out (first section)

Removed the whole section to avoid problems

Finally, to hook up the clutch pedal to the transmission release arm (one that we selected because it seemed to provide the best alignment and most travel against the transmission case; I don't know what year it's from), W and I both were thinking along the same lines in our separate, late night reveries: we both independently went out and bought some small turnbuckles and threaded rod and some OK clevises - although too small, it turns out.  The turnbuckles were a bust - they are too small or too big and have too much slop in them.  The threaded rod would work if we had clevises the right size: 5/16" or 3/8".

Clutch adjustment rod mock-up (with master cylinder rod)

In looking at my Ford parts catalogs, it turns out there was a 5/16" clevis used on Model As that seems just right.  I don't recall immediately what the application or part no. is, but I think it was for brakes.  [Note: found it; yes, mechanical brake clevis up to 1938 - 97012-S]  Later clutch adjustment clevises are 3/8", which seems too large.

Lastly, this week (and, as I write this post hoc, subsequently) W gave me some cool old (and random) hardware from his garage, some in ancient tin cans like Hollywood Shave Cream and Yan Chim Kee Cocoanut Flavored Candies.  Problem is, I don't have a good hardware storage system as it is, so additional stock, while appreciated, is just more stuff that I need to find a home for.

Turnabout and Out

Well, last week I was able to dig in and clean up the garage so I could spin the car 180* on the Harbor Freight wheel dollies it's sitting on. Was able to do I myself but sure had a sore back for a few days thereafter. Got it positioned under the beam and relocated the chain fall to give us some room to work around the front end.


I used my reproduction K.R. Wilson engine pulling fixture (you can read more about K.R. Wilson tools in my previous post here) that I got from Specialty Ford Parts in Rosemead, CA (no website; not sure if they still carry it).  It can be positioned two ways, depending upon if you're pulling just the motor, or the motor and trans.  We just pulled the motor and left the trans bolted in the frame with a jack under it to keep it supported (note to self: replace jack with adjustable jack stand, to save the hydraulic jack seals!).  (As a disappointing aside, I asked my friend to identify the other K.R. Wilson engine stand parts I show in that other post, but he didn't recognize them and chalked it up to them being military.  I don't think that's so, but have yet to find other information on them.  I'll have to keep looking.)


We unbolted the pressure plate to find to my disgust that the clutch disk had lightly rusted to the flywheel and the pressure plate.  My old-timer friend found to his disgust that apparently I had not run a tap down into the pressure plate mounting holes in the flywheel and they had rust in them, so he ran the tap into them using the taper tap I had.  It should've been a bottoming tap (straight sided), but I didn't have one.

He also said that his old boss (at the Ford dealership) would've slapped me across the face for leaving gunk in the pan below the clutch.  I think I thoroughly cleaned the oil pan but didn't realize that the hardened gunk can heat up and end up on the clutch disk, causing slippage.

We concluded the night with him providing me directions to compare the 9-1/2" pressure plate with a 9" to see if I'm lucky enough to find they use the same mounting bolt pattern.  Since that night, I've already returned the pressure plate to the friend I got it from and have gotten some leads on new and used pressure plates, and some dimensions to check my flywheel this week.

I appreciate my old-timer friend's advice to begin in the center, deepest section of the car as it's the most difficult to get to if something goes wrong.  Based upon his advice, I think we'll continue in the middle and work our way out.  With that in mind, this week I hope to continue working on the clutch and brake pedal assembly, looking at parts I'll need to purchase to complete the clutch linkage and checking out the various options I have for mounting the master cylinder, as well as checking out the used master cylinders sitting on my parts shelf.

If we continue diligently on the chassis, I think I would benefit from (once the motor's back in the chassis) relocating the car in the garage so I can pull off the body and set it on some former camper shell stands I have.  That way we'll have full and unobstructed access to the chassis to begin plumbing it and finishing up welds and body mounts I'd kind of forgotten about over the years of inactivity.

Back from Hiatus

So, last week I did more work on my hot rod in three hours than I have in the last three years.

I have an old-timer friend who lives down the street whom I knew before moving to this neighborhood.  He and began working on Fords in 1939 at the tender age of 13 for $0.25 an hour.  After the war, he eventually went on to graduate from the Ford dealership shop to the sales floor and went out as a sales manager.  After some time away, he returned to working on his and other folks’ early Fords (flathead V-8s and earlier) and other old cars.

I met him years ago through the local Early Ford V-8 Club when he helped me disassemble a banjo ring and pinion.  But, when I moved into the neighborhood, he wasn’t working on cars at all.  Fast forward to now, when he has returned to working on them and wants to help me with my car.

So, we recently began scheduling weekly car nights (he’s helping me to actually honor car nights that have been in my calendar for years, but sporadically observed) starting with my learning how to use the K.R. Wilson Timing Fixture he recently gave me.  While that session was a bust because the diving bell distributor I brought had a broken base, we decided to meet regularly and the most recent session was last night in my garage, taking a look at the clutch.

For whatever reason, most likely his insistence that a smoothly operating clutch is a must, my friend has for some time been concerned about whether or not my clutch was set up correctly.  For the record, I have a 9-1/2” clutch and pressure plate that apparently came standard in 1949-53 Ford and 1951-53 Mercury cars.  


Even before last week's discovery (I’m getting ahead of myself here), this set-up has been a problem: the thickness of the flywheel and/or ring gear caused me to have to trim down the thickness of the starter end plate to enable the Bendix drive to disengage upon starting (I have yet to reassemble the starter after that problem for several reasons).

So, last week we started out by trying to test how smoothly the clutch would release by installing a clutch release arm to the shaft and testing it with a piece of pipe or pipe wrench, since I don’t have my brake and clutch pedals connected yet.  First, we began by filing and fitting the three different clutch release arms I have in my stash to see which would line up best with the pedal arm and not be prevented from releasing by interference with the transmission bellhousing.  We settled on this one:


However, once we installed it with a drift punch through the pin hole and used a pipe wrench on the drift to release the clutch did we discover we couldn’t get the arm to move beyond pushing the throwout bearing forward to the pressure plate fingers.  It turns out they are jammed in place, and can’t move forward.  In fact, it appears that the clutch is already partly released by virtue of where the arms are jammed.

Sorry, no picture (yet)

It appears that the pressure plate fingers have too small of an open diameter between them because the 1949-later input shafts are much smaller than the 1948-earlier transmissions, so my larger input shaft is jamming forward the fingers of the pressure plate.

To further diagnose the problem, I’m going to have to spin the car 180* in the garage (which requires cleaning up the garage floor first) and pulling the motor to get to the transmission and pressure plate.  The likely solution: change out the 9-1/2” pressure plate and clutch for the even lighter 9” pressure plate and clutch (
that came in 1935-40 Fords) my friend’s been recommending all along.  This, in turn, would require redrilling the flywheel or getting another flywheel.  Sigh.

If it was easy, everyone would build a hot rod.

I’m hoping to get the garage, car, and motor ready to pull out my next Thursday garage night.  We’ll see...
