Hello, Had the Flywheel/Pressure Plate turned on the '35 Truck, looks great. However in looking very close there are many hair like cracks on the Flywheel metal. Are these Heat Cracks? Any problems/concerns with these? Should they be fixed/ignored, etc? Also since clutch, pressure plate and oil film of any kind generally do NOT mix, why did mfg. put a oiler zert on the TO Bearing? This might by why that entire enclosed space inside the bellhousing was soaked in oil. Any way to prevent that and still give the TO Bearing some lubrication? Thoughts appreciated, Tom

The cracks are hairline cracks but won't be a problem with the low horsepower engines from the old days. The oil inside the bell is more than likely from the engines rear main since the TO bearing should be greased, not oiled. I'm not all that familiar with trucks from the 30's so I may be all wet too,

In the mid 30's the TO Bearing had a small 1/4" round diam. hinged door on the side to add oil and keep it lubricated. I can see that too much oil added and with the centrifical force of everthing spinning around, is going to throw the oil everywhere.

I just got a '54 235 flywheel, 139 teeth I think. There are quite a few small cracks on part of the flywheel. I haven't had it resurfaced yet (I don't think they will grind out), but wondered if it is safe to use it with these cracks. Can they be fixed? Is it better to try to find another one (may not be too easy), or as noted in the first reply, will I be okay with a 54 235? I don't expect mind boggling revs,but I do want a smooth and reliable clutch. Any opinions on this ?
Thanks

be safe, replace the tranny input seal and resurface the flywheel...a few heat cracks won't hurt, replace the clutch disc and pressure plate and throw out bearing, pilot bearing in the end of the crankshaft....rear main if leaking....

Thanks, I was going to do all the other stuff, mainly was concerned about the cracks. The person who pulled it said some of the pressure plate bolts were loose, so I read here that that may have caused the cracks. I am putting a 54 235 into my 39 pickup and will probably have other questions to ask. You guys in Stovebolt are great!
