Tom got a bike in the machine shop with a broken upper shock mount. The owner of the mountain bike wasn’t able to get parts for the bike, so he brought the bike to Tom to see if there might be a way to fix it.
The bushing that was in the shock was wore out. Tom pushed out the bushing. He fabricated a new sleeve that would span the two suspension arms using O1 drill stock with a ground finish.
O1 drill stock is a oil harden drill stock and has a good rock well hardness.
Tom turned the OD and then drilled out the inside diameter to eight millimeters, so the eight millimeter bolt would fit through the two suspension arms. The metal sleeve is designed to span the distance between the space of the two arms and helps reinforce the bolt. The bolt fits into the middle of the sleeve. Tom fashioned two small snap ring grooves to keep the shock centered. The original design had two additional sleeves on the outside of the original sleeve. Tom eliminated the additional sleeves by using snap rings on each side of the shock. It should be a better fix than the factory sleeve which consisted of a thin sleeve over the bolt and aluminum outer sleeves.
