VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1937-1945 39 Chevrolet Okie Bushing

Gene do you have the out side measurement For front and rear This thing just may be O K,Thanks

The front and rear should be the same O.D. for either bushing. The Only number I can come up with is the O.D. of the torque tube is 2" UP FRONT WHERE THE BUSHING GO ON. A 1937-1939. So the bushing O.D. would be 2" minus the thickness of the torque tube wall. From what I can see of other associated parts the 1041-1950 torque tube is that same diameter at that location so that demension can not be used for I,D.

Gene, I found a Okie bushing that is stamped M-101 I think from what I have read that is correct one for 39,Universal joint fit awfully tight would work I think might just be crud in old bushing.I'm going to be knee deep in bushings but I feel safer on this one,Thanks

Robert,

The National I have has m101 stamped on the seal. The box end flaps are gone but written on the box is 37-39 Chevy. If I am reading my micrometer correctly the rear od is 1.710 and the raised portion by the u joint is 1.730. Overall length is 5 3/4". Does this sound correct , or close to yours?

Anyone know if the Filling Station has corrected the fit of their oakie?

Thanks

Dave

Dave, 37_39 isn't available,There Part #V-101,I think the bushing I have is M-102 Smaller inside My u joint won't fit in front bushing,40-50 was smaller 1/32 I think from Genes description. O D Mikes same as your measurements

Took the torque tube down transmission may have worked O K even with my driving 100 miles + or - with no oil in transmission,My vibration was caused by universal joint not having bolt holding it to the main shaft,Some more work done by P O.being the genius he was it shouldn't have been a surprise.

Put a posting in parts wanted for your Oakie bushing. Many of us have accumulated multiples of parts and don't even know what we have so include the dimensions you've finalized.

The Filling Station has the dimensions of their v-101 which seem very close to the ones I posted for the old National oakie; Dimensions: ID AT SEAL END 1.00" * ID AT LARGE END 1.345"; OD AT SEAL END 1.710"; OD AT LARGE END 1.723"

Still trying to round up a seal, my local O'Reillys has spent about an hour so far and order samples in twice, for some reason the seal number mentioned above does not come up.

I have a M-101 coming should be here Wed. or Thu.,Made by National Machine works in Oklahoma City Ok. It is stamped M-101 the true Okie Bushing,May be different from the one that I had it wasn't marked,I think it may have been a M-102 for 40-50 models,Universal on 40 up is smaller my u joint was a no go being a 39 and larger,not sure about driveshaft dim.,May be same for all yrs. I'll let you Know as soon as bushing gets here.
I think I will soak the bushing in oil before using to soften seal up as it is leather I think.

I received Okie bushing was Stamped M-101 on body of bushing and seal was stamped National Mach Wks M-101,They must of had seals made with there name on it .
Universal joint fits good ! 11/32 measures I D O D is same as the other one ,It was a M-101 40-50 I D was 1 5/16.
Will hold up on install The guy with the 37 3.73 is parting car out now,He just wants to tell me what I need,Power Glide I'm sure with enough extra work it is doable But easiest is a direct bolt in,Cheapest to. Don't want use up my bushings.
