SWB Posted March 24, 2007 Share Posted March 24, 2007 I'm replacing the rear drive needle bearings in my final drive R1100RT) with 660 Oilite Bronze bushings. Though the manual requires heat to remove the OEM needle bearing races, they came out with little force by tapping them out with a socket and socket extention. However, the manual also directs heating the neck of the case housing to 120 C degrees prior to installing the new bearing race into the housing. I still have lub in the final drive and there's oil around the housing neck area. I'm concerned about fire using either my heat gun or a torch (preferred; I have a good heat gun, but it takes forever to heat the case). (FYI, the bearing race is already in the freezer.) Also, I was going to use the socket and mallet method to press in the race, but that would mean either turning the final drive on it's side, or jury-rigging something to prop up the final drive against a concrete wall. Or, I can do what the manual directs, and press them in. I've done that before using a bolt through the middle, washers at either end, and a nut to tighten and press in the fitting. Problem with that was when I installed the swing arm fittings, the directions said heat to 80 degress C, freeze the bearing, and press in. As soon as the bearing made contact with the swing arm housing, the temp dropped to about 40 degrees C, and I had a heck of a time getting those bearings to seat. Right now, I'm probably going to forget about the heat, and try pressing in the race using the nut-and-bolt method, rather than accept the risk of fire. I think that the race can take more pressure with less likely hood of damage than than a roller bearing. Would appreciate ideas and recommendations. The final drive is an expensive component to trash by inexperience. Thanks. Link to comment
