differential rod bushes
« on: March 20, 2018, 04:27:25 AM »



Hi Guys, just quietly working away on my 1990 K1, one day she will be back on the road..... Just put in a new clutch, greased the splines, new swing arm bearings etc. Putting her back together and I decide to change the differential rod bushes.... yes thats right, call me anal, but thought it was a good idea. Ordered new bushes (thats no 2 & 3 on the parts list below which are both the same part number so exactly the same). Now I am waiting for them to arrive from Germany at a heathy $80 AUD. So I am about to take out the old bushes, has anyone done that? I assume I just hit them with a hammer till they come out, and if they don't come out then hit them harder? Manual doesn't say how to remove them, they seem well stuck in there.


Appreciate any advice!  :bmwsmile

Using a hair dryer or heat gun, heat the fitting that holds the bushing until it's warm to the touch, apply penetrant, have a café cubano, wash the coffee cup, then drive out the bushing using a socket of appropriate diameter. Repeat if necessary. Alternatively, apply freeze-spray to the bushing then drive it out. Hammer too hard and you'll break that support. Don't unleash that terrible beast within. :giggles

Did exactly that, lots of heat & rost off & 20mm socket and press, took a lot of pressure before they moved out! All done and new ones pressed back in. Thanks very much
