Rubber Bushing Isolation Mount Replacement
Exhaust posted a topic in Restorations, Modifications, & Customizations
I think this is a c 161, recently picked it up. The motor was getting too much movement from worn out rubber bushings so they had to be replaced. I wasn't interested in spending the money on the rubber OEM bushings so I used washers instead. Here is the process I used, I'd be interested in any opinions you all might have, let me know if you recommend something else or if you would have done it differently. Before modification. Rubber mounts removed, wood block to protect fingers. I did the front two mounts then the rear two. When replacing the front mounts (or the rear), I loosened the rear mount bolts to allow the motor to move around more freely. It helped to get the bolts out and allow install of washers. The two mounts at the bottom of the picture show before and after of removing the rubber bushings. You also see I had to grind about 1/8th" off of the side of 4 washers for each mount to allow room for fitting into place due to nearby bolts. The inside diameter of the washers were a little bigger than I would have liked but the way they stacked up in sequence will allow them to be plenty strong, I hope! Used a cheap wood saw to cut the rubber from the metal. Forced the cylinder out of the rubber interior bushing and cleaned the rubber off the cylinder. Doesn't need to be all that clean, just good enough to allow it to move into place when mounting. Mounts in place with washers. You can see how 2 washers on top and 2 washers below needed to be ground to allow space between the nearby bolts. They are not bolted tight at this point but this was basically the end. I first tightened the front 2 mounts to pull the motor forward so the drive pulley would be close as possible to original position. Not confident this made any difference but I did it anyway. A picture of the front mounts with washers installed. That's it. Hope this might be of use to someone on a later date.- 9 replies
