Model T Ford Forum: Forum 2005: Transmission- oil pan questions.
Top of pagePrevious messageNext messageBottom of page Link to this message  By Mack Jeffrey Cole on Friday, May 04, 2007 - 06:55 pm:

Ok, over the comeing months I will be working on a engine and transmission for my T project.I have located a engine that has had the machine work done and ready for assembly at a very reasonable price but it is just the block with pistons and rods and crank.
I have several oil pans.
What things do I need to check about the oil pans I have to see which 1 is the best to use?
Are these checks something I can do without special tools?Know the petcocks for the oil checking need to be in good order and no rust through but I am wanting to make sure there isnt other problems like being bent or something.

Also.I have at least 5 transmissions. 1 or 2 26-27 and the rest are 25 back.Obviously it would be best to use 1 with the larger brake drum.
Can I use the later transmission with a older engine block and oil pan?
Also,in selecting a transmission,other than the obvious need to check for missing parts and rust,what else do I need to check for to select a canidant for my project?
I know there are bushings and such in there.Can I check those parts without a complete disassembly?
With a good selection of mechanics tools and a workbench in a good dry shop can I buy the rebuild parts and do it myself or is there work that may need to be done by someone with more knowledge or special tools?
I dont mean to sound stupid,but I fiqure it would be better to ask basic questions than to ruin a transmission.
As allways,thanks for any help is appreciated.

Mack J C, if you are using a 26 trans you will need to use a 26 pan and hogshead. They are fatter to alow for the larger brake drum. You can use earlier pedals if it is for a earlier car. You can not use a clutch pedal from a non starter car, it will not clear the bendix cover.
Good Luck

One clarification: You can use a clutch pedal from a non-starter car, if you graft on the little arm from a later pedal. My welder guy, Shirley, has done it.

Any 4-dip pan will clear the later brake drum. With the 4-dip pan, you should have these reinforcing straps, and you could use the upper braces as well.

I use a later 24-25 transmission cover with four dip pan and 26 transmission, in my pre 26 cars. The cover just clears the big drum although you have to use narrow band on the drum because of the pedal location.

Jerry, That dosn't give you any gain in braking power. It only makes it easier to get at #4 rod and the rear main. Not worth it in my book.

Mack, you can do the transmission yourself, but if you need to replace the bushings, you should have someone with a lathe to ream the bushings, as it is easy to get things misaligned if it is reamed by hand without the proper fixture. Also, it is well worth taking the time to balance the flywheel and transmission drums (after checking them for cracks). This can be done as it is described in the MTFCA booklet "The Engine". Another thing, go to Harbor Freight and get a dial indicator(they are cheap there!), if you don't have one. You will need it to dial in the flywheel and transmission shaft. There is a huge difference in performance between a balanced and true engine as compared to one put together as is.

Andy--your right it doesn't give me any additional braking power, it does give a 26 drum with shoes on the lugs. A few years ago a friend was starting up at a traffic light, a pinion gear split in half, seeing that convinced me outside brakes are necessary, the inside is only set to drag a little, so I'm really not concerned having an internal narrow band.

Owning/repairing/operating Truck, Loaders, Forklifts and other equipment for a lot of years has programmed me to modify, change, improvise and fabricate whatever I can to eliminate chasing down a Truck sitting on the side of the road, or a Loader or Forklift taking a dump right in the middle of the day, but if it does become a problem there is a good chance the unit has had some things done to it during regular repair sessions (with regard to maintaining the safety factors) to make a quick repair when the need arises.

To me the four dip pan is a change that makes a future repair a little easier and faster. it makes it easier if a rod needs attention. If the third main needed attention, my guess right now is I would pull the engine and stand it on it's tail and do my thing without removing the pan, unless of course you have something with threads slip out of your fingers. Additionally the four dip pan gives the extra width for the 26 drum, which if I desired to have a wide band I would go in the back building for a 26 wide pedal transmission cover, being old and lazy I just don't feel like making new floor boards

B-b-b-but you don't have to make new floorboards if you just move the early pedals to the late hog.

Interesting--Never really gave the pedals any real thought. Just sent a 26 block to the machine shop, scrounging around in my transmission stuff noticed we have several 26 covers and only early covers. Plan on building another extra complete engine, I will use a late cover and early pedals, plus additional bonus of supporting the transmission on the back of engine. As stated being old and lazy I won't have to make new floor boards

Thanks for the input fellows.I should before nightfall finally get the rearend under the chassis and get it moved into a small shed so I can work on the chassis and such without haveing to uncover and recover with a tarp all the time.it will be a little cramped but I will be able to work on it at night and when it is raining,something I aint been able to do till now.
