Engine installation in a TT truck
Helping install an engine in a '20 TT truck and ran into a couple of problems. Do the rear motor mount ears go over the top frame rail? and if so, then the 2 side bolts do not line up. If the rear mount ears go inside the frame rails, how high are the blocks for the ears to sit on? Also, is there a difference in oil pans between car and truck with reference to the height of the rear mount ears. And lastly, is there a difference in height for the shoe on the e-brake shaft between car and truck? Thank you for any insight you can provide.

Re: Engine installation in a TT truck
Rides on top like the car. I am pretty sure the wood blocks were not used on the TT. The cam on the cross shaft is taller for the TT's. No car and trucks used the same pan.
I know the voices aren't real but damn they have some good ideas!

Re: Engine installation in a TT truck
Everything mounts the same as the car with the pan ears sitting on top of the frame rails with the same pan. The brake shoe on the TT is quite a bit taller, however, since the brake lever mounts under the frame and the TT frame is quite a bit thicker.

Re: Engine installation in a TT truck
I checked my unrestored 1924 TT and the engine pan ears are mounted to the top of the frame with a wood block and side bolt like the car, but the top bolt has a spring, castle nut, and cotter pin, similar to the radiator mounting.

Re: Engine installation in a TT truck
If your pan ears don’t line up with the frame holes you have a bent pan. May just be the ears but best to remove the pan from the engine and have it properly straightened on a pan jig. Bent pans are one cause of broken crank shafts.

Re: Engine installation in a TT truck
Removing the engine/transmission from the pan to get it straightened entails a certain amount of work. Not getting it straightened can entail even more work, plus lots of dough.
The inevitable often happens.

Re: Engine installation in a TT truck
Jeff, you post that your TT is original, I am not doubting it just I have never seen springs like on the radiator to secure the pan ears before. I like that idea since you tipically only finger tighten those nuts and bolts on the pan ears. Appearantly the TT frame moves more than a regular T would out in the fields and so forth. Other than that I see there is an insurance item of motor belly support on that truck which I have never seen before. I have a motor belly support similar to that on my 21 and everyone gives me a weird look as to why. The whole setup got me thinking and I like it. I was not trying to hijack the post just pointed out a couriosity that cought my eye. Frank

Re: Engine installation in a TT truck
Frank, I read about using radiator springs on pan ears in "Tinkerin' Tips". It is not an uncommon "upgrade".

Re: Engine installation in a TT truck
More information from the Ford Service Bulletin, May 1925, vol 6, no 5, pg 22: Crankcase Arm Bolt on Trucks
We have discontinued using the side bolt and block for the crankcase arms on the TT Truck. This allows the mounting of the engine to be somewhat more flexible and reduces the possibility of cracking crankcase arms on trucks used on rough roads, etc.
The change discontinues the following parts for use on trucks:
T-3073-B Crankcase arm bolt-side
T-3083 Crankcase arm block

Re: Engine installation in a TT truck
Another common problem is that almost nobody realizes that T car and TT truck front crossmembers are different. It’s not uncommon to see a TT with a T front crossmember and there is a severe mis-match between the engine water outlet and radiator water inlet.

Re: Engine installation in a TT truck
thank you all for your informative replies. Of the 6 TT frames I have recently checked, 3 of them have the e-brake shaft still installed with the top of the neutral shoe 3" from the edge of the shaft. These look to be original fitment as the bolts holding it together still have the split pins installed albeit very rusty. the other frames do not have the e-brake shaft. All of the frames have only one hole in the side where the pan ear sets, which is 2 1/2 " from the top of the frame. On all 6 frames the horizontal bolts for the pan ears are 1" lower from the top of the frame compared to the car frame, so they would not fit. (ref: picture shown above). Could this be a difference between Canadian and American produced trucks? Also, regarding the front crossmember, all are original truck crossmembers.
