Chevrolet transmission bearing numbers

[Bob Carriere]

I don't think that 1207 bearing will fit.....

The GM tranny bearing as SOLID STEEL ( bearing race) insert that slipsover the countershaft..... and is not included...... when I sourced the same bearing in Ottawa the insert from the old bearing was a few mil to big or too small and would not fit the counter shaft.

If this is an issue I will go back to my parts box and measure in mil. for accurate slack........ I still think it not readily avaialble in North America.... nbow in Europe I believe Alex or someone else fround a suitable replacement.

Cheers

PS......Will look for pictures of original bearing in my files.

Bob: I am always up for a part number challenge. We'll see how Bob P does in his quest, and if it doesn't work out, then we'll go the measurement route.

For some reason though, I think we went this route on the forum a couple years ago. Was it for this bearing?

The GM part number shows on this list of cross reference as well, which has a hundred numbers for that bearing: https://mibearings.com/index.php?mai...ucts_id=281388

And of course, keeping an eye on ebay, or searching google for the Chevy part number should also get you there.

I searched the MLU postings for bearing data and was able to find reference to the caged pilot bushing only. While the number crosses with a couple of different suppliers it is officially discontinued. I am sure there are some out there yet as, so far I have had no great difficulty in getting all brake parts, seals etc B,P,

Some of the crosses I get for GM141854 are Timken J281248 and Bower possibly Bower 93424

Both are presently on ebay starting at 9.99

In fact, if you run the 93424 number on ebay you will come up with quite a number of them, including made by Hyatt, who is listed in the GM book as the cross reference.

Hi Rob
Great find , esp as my local jobber says all related interchange numbers are no longer available. Perhaps another alternative would be to use correct length &dia pieces of dowel stock with no cage..my '76 jeep trany was put together in that fashion...wont hear about rest of bearings until next week BP

[rob love]

Dowel stock would never last. The little needle bearings found in many transmissions and transfer cases are very hardened. They are also, as far as I know, unique to their applications.

.... the last set of treads on this C1207 bearing was NEVER resolved to my satisfaction......

I need to search my photo librabry...... but I am stoned on pain killer,,,,,so somehwere before they completely wear off and I take the new batch I will try to find that illusive info.....

From waht I recall the bearing guy telling me is that everyone of the suffix or prefix to a bearing number means something has to how it is constructed or inrtended for.....

For the sake of the hobby we need to sort this one out.

Don't roll away on a loose bearing...... getting a shot of something into my hiop joint tomorrow....so may be much better or much worst.....

cheers
