My 1926 Roadster does not have the wood block but does have the 2 straps at the top mounting bolts. I was reading somewhere here that they started using them on the later model but was not sure if it needed the wood blocks and the straps or if the straps took place of the blocks.
Let me know what you think. Should I make a couple blocks and put in there or are the straps enough?
The blocks help to keep the frame from sagging (which is a common problem with 26-7 T's)
OK would anyone know the dimensions of that block. I have a hard time searching for things on here but seen it not too long ago.
Gerald, here you go.
Or if you don't feel like making them, these work quite well.
I put them on my 26 rpu but didn't put them on my 26 coupe. If it helps I guess it's worth doing but I have heard yes and no on the forum as to if they help. Tim
Your car uses the new style square wood blocks. Way easier to use than the earlier style.
Gerald, You could more than likely find them at Gaslight Auto Parts right there in Urbana. Jim
Looks like them might have them. I have a list and was stopping up there soon anyway. They are always helpful.
Les, just wondering.Why is the 1926-27 frames more prone to sagging ? The encyclopedia says quote "In early calendar 1926 heavier steel was used for increased strength. A letter to chassis suppliers, dated February 28, 1926, specified the metal to be the same as the truck chassis (Type “L” steel, .180-.200 inches thick)". By the way my roadster frame is sagging a bit I think.
Post by Trent gives insight to heavier frame, as bodies got heavier.

The reason the engine block to frame straps were added was to reduce crankcase arm breakage. According to Walter Fishleigh's papers (BFRC Acc. 94), the Model T had a problem with crank case arm breakage because of the stresses put on the arms by the pressed steel running board arms. This was not a problem on the TT trucks because the used a much different design of running board arms that did not stress the crankcase arms. The Ford engineers found that by adding the engine to frame straps, they could pretty much clear up the crankcase arm breakage problem.
My October 1926 coupe did not come with the straps, but after reading about why the engineers added the straps, I have since added them to my car, even though they are not technically correct.
In the spring of 1926 the engineers found that the heavier bodies on the improved cars was causing a frame sag problem. The way they cured that problem was by going to a heavier gage steel on the frame side rails. Late '26 and 1927 Model T frame side rails are substantially thicker than post-2500 side rails.
