I have a 26-7 Transmission and hogs head that I want to put behind a 23 block on a 3 dip pan. Somewhere I heard that the brake drum will hit the pan. I have another car with a 4 dip pan and the back half of both pans look identical. I don't want to put the 23 engine and 26-7 transmission together if I can't put a pan on it to button it up. 26-7 transmission in a 3 dip pan. Will it work?
Appears you can.
Main issue is fit is ok, but not with the wide brake band of the '26-27. That wider brake band will hit the side of the 3 dip. Fix is to use a narrow brake band, lose some of the braking surface of the wider brake drum of the '26-7 but that way you can use a 3-dip pan.
why not just use a 4 dip pan ?
Mike, Either he doesn't have an extra 4 dip, or he doesn't want to go to the trouble to change it out. Those are the only reasons that I can think of.
The bigger problem is the fact that you will need to use the 26-7 hogshead to get the clearance for the larger brake drum. If that is so, be sure you have clearance between the ears on the hogshead and the back of the engine. If the ears contact the back of the engine, you will get misalignment of the trans and engine. The end result will be a broken crank at the rear flange. Just like the one a friend has asked me to fix.
A little filing on the ears and the 26-27 hogsheads will fit just fine.
The problem is the wide brake band on the improved trans, I think, when combining a 26/27 trans with a three dip pan. The wide brake drum will fit, but you'll have to use a pre 26 hogs head with a narrow brake band.
Don't know if a narrow brake band and a 26/27 hogs head will work with a three dip pan - anybody tried?
When you use a '26 transmission with the wider brake band, the brake pedal is set back about a 1/4 inch or so and the narrow band hogs head does not line up.
Dad and I tried this a few years back, wide band with the narrow hogshead did not fit as the centers on the band ears between the narrow bands and the wide bands are different.
You could put the earlier pedals on, but you will still have the brake pedal offset.
Hope this helps ya.
Oh yeah. You also need that indent at the rear of the pan to clear the wider brake band of the improved tranny.
You need the '26 pan with the indent at the back to clear the wider transmission brake drum. Also, the earlier hogshead will not fit to the wider drum as the center of the brake band ears sets back farther than the center of the ears on the narrow brake band.
Low and reverse will fit, but there is a difference on the brake band ears.
Dad and I tried this a few years ago, his idea was to get a better brake, but the '26 pedal sets back.
You could try using the earlier pedals, but the brake pedal would still be set to the side like the '26 T's.
Hope this helps ya.
AAAh! Stupid internet!!!!!
I wonder why it took Ford so long to incorporate the wide drum into the engine? They had to have known in 1924 that they were going to do this, when they introduced the 4 dip pan.
Thanks MTFCA, I guess I'll go hunting a four dip pan. Chuck Smith
Chuck, the three dip has one advantage, it's stiffer than the four dip - the end of the trans may flex a lot on an engine with a four dip pan but without the 26/27 style bolts connecting the hogs head to the engine block. A lot of flex in the fourth main area may increase wear on the second main and add stress on the crankshaft. There were a lot of '25 Fords made with this configuration though, and I haven't heard anything about them breaking down sooner than earlier and later models?
At least one strengthening feature should be used with a four dip pan - the corner brackets:
(can usually be found at ebay or where used T parts are sold..)
Those brackets were used on all 4 dips I think, but I use them on any year. With a bit of filing, and some oblong holes they will fit.
