Hi everybody, can someone help me to identify this flathead clutch & bellhousing. a french seller propose me this parts. i think this parts come from a truck, which type & year? it seems to me that the adapter bellhousing is deep compare a cl***ic for car. i'm not sure but i count 114 teeth on the flywheel ring gear, instead of 112 . my engine is a 53 Merc, and i have the plan to adapt a T5 manual gearbox. is this adapter alright? hope to have some information about, and what is the value for this parts in USA. Thanks in advance sincerelly Jean Phi [/IMG] [/IMG]
Well, that's got to be an 11" clutch, very heavy. Wheel can be redrilled. Bellhousing is heavy truck, fits only big 4-speed unsynchronized truck trans, but some people use it as the basis for making an adaptor for modern transmission. I believe that bellhousing was used on both early and late trucks...and flywheels differ. Investigation: First, ask if there's a serial number, probably 59T******, on the bell housing near the little tin plate. If so, bell is early and likely the flywheel is too. All flathead flywheels except automatic have same tooth count. 11" flywheel can be redrilled for lighter 9 or 10" clutch.
Jean, here is a fairly in depth listing of bell housings. Hope it can be of some use. Dave http://moes-garage.spaces.live.com/...derID=cns!4FC3316B3CBDCA99!3634&_c=PhotoAlbum
I just bought a heavy duty transmission with one of those bells for $25. The transmission went unsold on ebay because of the heavy duty status and I won another auction for the motor. I made the offer when I picked up the motor. I figured it was worth that if I chose to upgrade the trans in my '46 F 1/2 ton. I have seen those bells sell for as much as $80 since they can be used to adapt. Edit. You will also need the other 1/2 of the bell housing to finish adapting the transmission. That bell will bolt to the back of a 59A style motor which had 1/2 the bell cast on the motor.
Hey I just sent Jean Phi a PM about some evil bay prices on these parts. I have a couple of flywheels in my garage, but haven't had the time to look over them to give Jean pointers. After looking closely at the evil bay flywheels I noticed that one only uses 4 bolts to the crank and the other uses 6 bolts. Of course the pressure plate holes for the 4 bolt flywheel matches the the one he posted, but the 6 bolt flywheel is listed for the newer (8BA/8CM) motor. Any advise for Jean on the different flywheel / crank bolt patterns? I will check on my flywheels this evening, as I have one with each of those pressure plate hole patterns.
All are 4-bolt with two dowels! Left picture has stock 4-hole plate COVERING the 6-hole flange, leaving only the bolt holes exposed. Bolts are best use to secure in compression, while pins take radial load. Wheel has 6 holes. Right wheel is for late Merc B&B pattern clutch. Right is for Ford Long, I think 11" truck version.
Duh, I remember the dowels and the plate now. The one I have with the pattern on the right came from an 8BA that was likely at one point in a Merc. It came in my '46 half ton and had a 10" clutch. The one I have with the left pattern came from a 59AB that supposedly came out of a truck, it has an 11" clutch. Bruce, thanks for setting me straight on the crank bolts, I probably would have just confused myself more when I looked at both of mine, and they both would have 6 holes

The bellhousing is the correct bell housing to use with the billet t-5 adapter. This unit appears to be from a 1940 and up truck. For this conversion on a 49-53 block: you will also need the truck bellhousing (the parts that bolts to the block) and reduces the size to the 4 speed trans case as shown, you then need the 4 speed case portion that you show, as it has the clutch throw out shaft, then you need the new style billet adapter plate to bolt the t-5 to the trans case. You then need a clutch disc from an a chevy Astro van or similar . Measure the face of the pressure plate that you show, if it is 11" it will work but it is big and heavy and a smaller pressure plate is suggested. I also suggest that you purchase the new style T-5 adapter as it will accommodate the Ford throw out collar and uses the Ford throw out bearing. Since you did not indicate your application, you may also have to change out the clutch shaft to an earlier version and a clutch release lever to match.
