Afternoon all. I'm currently rebuilding my 300 90 on a Marsland chassis and as the title I have a query on the upper link.
The chassis came with M16 bolts and sleeves, I've come to fit me polly bushes but the OD of the bolt sleeves is too small for the ID of the new bushes.
The sleeves that came with the bushes are bigger than the bolts.
The two sleeves slide together near perfect but I think they'll bind up over time and fail quicker than the bush, defeating the object of going polly!
Anyone come across this and how did you go? Cheers, marchy.
 
Regarding the sleeves use lots and lots of grease as Ive just swapped the front radius arm bushes in mine and even though I greased them 3 years ago when I fitted them the sleeve had seized to the bolt, utter arse to get apart, one hours job took me three, was not impressed,Ive gone back to std rubber bushes.
Not sure what make you have but mine were flo flex and although there was no wear on the bushes they had sort of relaxed allowing the axle to twist back and I had lost the caster angle along with the steering self centring ability which made it fun coming out of tight junctions, best quality britpart rubber ones! and all is good again.
As for the std bolt size Im not sure, but think one end is 27mm spanner and other end is 30mm spanner so certainly bigger than m16 shank size.
Ps the sleeves should be clamped up tight between the two fixing plates by the bolt.
 
Thanks for replying. I know exactly what you mean about the amount of time taken, everything at the moment seems to be taking an age.
I've been having a search around and I think the larger bolts were 3/4'' (19mm ish) so that would go with the bush sleeves. Too big for the holes on the chassis.
Going to give a local engineering firm a call in the morning to see if they'll turn me a couple of sleeves if not might end up welding these together to stop the binding.
