timing side bush
« on: 29.01. 2012 14:57 »
hi all need some advice on were to get my timing side bush/crank clearance machined looking for some one within an hour of Gloucester or Bristol, don't want to go the SRM route nothing against them but would rather use a smaller more old school type of engineer. I am a toolmaker myself and i did one many years ago but now cant get homers done at work its called the recession or so my boss tells me many thanks Paul

bikerjohndavis sounds as though he has just the right place for you. Any Engineering Company can do it. C and D have a good range of undersizes bushes ready for boring. I like your word homer, where I come from we call them foreigners. All the best.

Glad I could help. It seems that the current thinking is to use a maximum oversize bush and grind the crank journal as little as possible to give it a good face then match the bush to it rather than take it down in 10 thou stages. This should allow the crank to survive longer.
