Chevrolet transmission bearing numbers

[Alex van de Wetering]

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

Here is a picture of the replacement I bought from ebay. The top one is the original ( I am trying to show that it has a bit too much play between the parts.....), the lower one is the replacement.

Yes, and also other differences....like the number of balls in the bearing...or the material; I recently bought a replacement seal that was a full rubber part, while the original was steel with leather (or felt....can't remember).

Alex, it will be the diameter of the rollers that is the important bit.

Just following along and getting some parts ready for rebuilding my C15a transmission.

Is this the correct rebuild bearing and gasket kits?

Have you considered taking the old bearings to your local industrial bearing supplier and asking them for a quote? I would do this in Ottawa and expect to see a better price than a restoration supply house and typically either in stock or very quick delivery. Recently I did this for CMP 15 Cwt trailer wheel bearings, the supply house had a variety of suitable bearings at varying prices. They described some of them as more reliable for sustained high speeds and heavy loads than others. Several years ago, I also did this for C15A transmission bearings and all were either stock or next day availability.

[Jordan Baker]

I'll probably be doing that. I still have to open up the transmission first. Also the fillingstation doesnt have that item in stock.

Would that gasket set be the one Id need?

The vast majority of deep grove ball bearings use METRIC sizes.

the last 2 digits of the indicate the bore size.

04 equals 20 mm bore
05 equals 25 mm bore
07 equals 35 mm bore and so on up to 99

60 62 63 and 64 are comonly used to replace older series numbers

62 series is the most common series.
60 and 618 are smaller section bearings , smaller balls.
63 and 64 series bearings are bigger, heavier.

6203 is the comon generator / alternator bearing 17 x 40 x12 mm.
6207 is a comon front gearbox bearing 35 x 72 x 17.

Z or 2Z = shields.
N = circlip grove.

there are pages of other suffixes .
I hope this helps,

and i can't find a post where anybody has a part number for the cage bearing, maybe I'm daft.... okay assume I'm daft, but I still can't find a part number.

[Jordan Baker]

Harry. Here is what I used.

It measures just under 1-1/2” long.

93424

[Harry Moon]

perfect, I'll go look

[Bob Carriere]

Usually available on Ebay....

Last batch of four for about $10.00 US each..... shared with Gordon Yeo.

They do come up regularly....original made by Hyatt now SKF and others.... but you get better results by just searching bearings 93424.

Good luck
