Which hydraulic release bearings work with this? The engine is a '51 Mercury flathead. Stamped steel style bell-housing, I think it is from a '49 Ford. Trans has the front bearing retainer from a Saginaw 4-speed. Trans is mounted directly to the bell-housing without an adapter.

We recommend release bearing number 91025610, a ¾ master cylinder, and a line connecting the two in AN4.

46 Flathead V8 to 32 Three Speed I have a 1928 Model AV8 Pickup I am putting together. Using a 1946 Flathead V8 and a 1932 three speed. I had the motor and tranny hooked up and in the pickup, and thought the motor had seized up. I loosened the bell housing bolts and the motor turns over fine. The pressure plate must be making contact with the bell housing Therfore I think I must have the wrong pressure plate. Can your tell me which pressure plate I should be using. Thanks Bruce

If you used the 10 ½ diaphragm pressure plate what throw out bearing did you use? If you use the original style for the Long Style pressure plate this will not work. You have to match the throw out bearing and pressure plate. The 41 and older used a 9” clutch and pressure plate and 42-48 used the 10”. If you are using the OEM style flathead throwout bearing and linkage then use 91015657 and 91015654 and if you have flywheel 91015627 should have the correct bolt pattern. If you have everything switched to the diaphragm style then I would suggest a 10” and you may have to re-drill the flywheel. Also some of the flywheels are not deep enough to use a sprung clutch disc and the disc itself could be hung up on the bolts. A little trial and error fitment would be suggested first as it may just be a casting ridge or boss that could be ground off for clearance.

Will this work with Chevy motor in 52 ford truck? Hi I have a 52 ford truck and was going to put the SBC motor in it. Will this work with your adapter instead of using the Ford long style pressure plate and will it work with the stock ford release bearing. Thanks for your help, Dennis

The use of the Ford Pressure plate on the Chevy flywheel may require drilling the flywheel to match the bolt pattern. The stock Ford throw out bearing will not work on a diaphragm pressure plate and requires the use of the Long Style pressure plate.
