I contacted
[email protected] and asked for dimensions and instructions for installation. Here is their response.
“
The IR1502 inner race is 1 13/16" outer diameter, 1 9/16" inner diameter, 1 3/8" wide. Sorry, no installation instructions for it - it would press onto the axle shaft and work with the C1502 axle bearing.“
Their response is contradicting as 1-13/16” (1.8125”) is considerably smaller then the OD (1.876”) of the axles used in our 1/2 ton trucks. They further said it fits a C1502 bearing in which cross references to (Hyatt OR1502), the bearing I’ve removed from my truck.
I responded to the email from “Sales” and asked if they could use a micrometer to measure the OD of the sleeve.
I have done some further research on the sleeve IR1502. Again GM interchangeably at it’s best. IR 1502 (As klhanson suspected is Hyatt IR1502, inner race) turns out that it’s GM part 111122 listed in “1929 - 1954 Chevrolet MASTER PARTS and ACCESSORIES CATALOG” as fitting 37-40 Comm vehicles. It also fits 35-55 Buicks as described on the Fusick Automotive Products website and possibly others. It is mated with GM part 111121 (for those vehicles and years listed). This is further evidenced by an eBay listing and a listing from the Filling Station.
GM part 111121 (Hyatt OR1502) is listed in the Chevrolet master catalog as fitting 40-54 1/2 Ton Trucks. In conclusion, this sleeve should work as a repair sleeve for our 1/2 ton AD trucks.
I ordered two of theses sleeves so my next question/quest is what kind of fit is required to install this sleeve.
