Still busy putting in a couple of hours here and there rebuilding a cota 348. The old swinging arm bushes were shot so ordered a new kit with the outer and inner bushes. A very good friend of mine reamed the swing arm holes , then pressed in you bushes using a milled template of the inner and again gently reamed the inside of the bushes so the inners go in smoothly (little bit tight at the moment but I've been assured they'll soon free up!!). Question is that I have the oil tube linking both bushes with the nipples. Should I just grease them on assembly and forget the tube or oil them and fill the tube with oil as well. If so what grade of oil/grease do I need? Don't really want to get this bit wrong after my mates hard work....

Lithium grease on assembly, then the oil tubes are there so why not use them.

Hopefully you will never be in there again.

Bit surprised you had to have them reamed. Mine never wore out as I kept pipe full of EP 90 - 140) but I did help some people replace worn ones on bikes the had bought and reaming was never needed.

At some point in its life, the swinging arm had been chewed by the chain and blob welded, when I knocked the old bushes out the chain marks were on there too. To say they were worn is an understatement, you could rattle them up and down, forwards and backwards. This is a barn find rebuild so expect some anomalies and I'm guessing those bushes have never been changed in its lifetime. They were dry, the nipples and oil pipe were blocked and full of mud so thought sod it I'll buy the whole new kit off inmotion. When it came I noticed than the swing arm holes were slightly ovalled (probably due to wear and tear) and so hammering a bush in by about 2 cm started to nip it and no longer let the inner slide in, hence the trip to my friends to have them reamed. We're talking in thousands of an inch here not taking huge chunks.... Shes an old girl who's had no TLC so these things are sent to try us...

Thanks for the replies Lithium grease and oil it is then... Cheers.
