I'm trying to identify a rear axel in my bus. It is a Thomas 1985 International 9.0 IDI engine Allison 545 Transmission. The rear has a tag . I can find no cross refrence to the information on it. It is a Hayes Dana axel part number H.D. F8290550 . Any ideas ? I would like to change out the gear set for higher gears. It looks to be what I know as a Rockwell rear end.
easiest way to get an ID on the axle is to take the VIN to an international dealer and have them run it, the resulting sheet will have all the mechanical specs of the chassis including the axle type and ratio
