Chevrolet transmission bearing numbers

[Bob Phillips]

As of today I can get the following bearings from my local jobber;
GM # 903209 crosses to 6209J cost $64 CDN frt mainshaft
GM#901307 crosses to 307J cost $134 cdn rr mainshaft

You might to better to check EBay for NOS bearings at this price
caged pilot bearing 141854 is discontinued

I rarely buy from a jobber, or NAPA any more. Rock auto in the US is often my go to, along with summit racing and of course, ebay and amazon.

Just replaced the front rotors on my truck along with all the wheel bearings and new seals (even a spare pair of seals for next year) and spent less than I would have for just one rotor here. I am happy to buy local, but they have to be at least a little competitive.

So it looks like NOS varieties of the 6209 bearing are available on EBay for US $10-30 and at Rock Auto for $29.78

for the transmission in the C15A, I purchased a transmission overhaul bearing and gasket kit, cost was about $120.00 US from The Filling Station, there on line and you can order thru the net, the only item incorrect was the input shaft bearing or main shaft bearing, I had to call and give them additional info to get the heavy duty bearing, see the picture of the bearing on the right this is the original and is longer than the one on the left that was sent in the bearing kit.

Just a heads up....this guys is selling replacement (needle cage) bearings for the Chev main shaft on Ebay:

http://www.ebay.nl/itm/172104151100?...%3AMEBIDX%3AIT

Ebay object number: 172104151100

I bought one about a week ago and have fitted it to the gearbox in the meantime; will post a picture in the next few days.



Different manufacturers often use the same part number for the same bearing, so it helps googling just the part number without the original manufacturer and adding the word "bearing" or "seal"....and see what comes up. Sometimes this results in replacement bearings available through agricultural suppliers...or ads on Ebay. It's also how I found the ad above.
Google searching will often also give you sites with cross reference lists.

Good point Alex, most (of not all) bearing manufacturers follow a Basic bearing designation system.

Cross reference lists and calculators are available - here's one quoted below - to help find the bearing one needs.

Even though a bearing may match the type and basic dimensions, please be aware they are produced in many different qualities. In general the rule of thumb applies: you get what you pay for
