Quick help for suspension service
-
@declan I would use a metal polish, a soft polishing mop on a dremel to cure the that as much as possible.
It sounds silly, but any sort of corrosion on this part will not only affect the handling, but also the longevity of the needle bearings it runs against. The frictional forces at work on the suspension components shouldn't be overlooked. It's far cheaper to replace an £8 collar. than a £30 needle bearing. SWING ARM BEARINGS ARE EXPENSIVE!!!
FYI to anyone who wants to powdercoat swingarms lol

@declan Item 13 is the linkage, lots of bearings
In the event you have a collar, and no bearings (as designed from the factory) you have to be even more strict. As the you won't have the flexibility of simply replacing the bearing, you instead have to replace the whole item.
Oh so for example, Cam Shaft Journals on a Four Stroke engine. Since the cams run directly onto a Journal, no shells or bearings, if you damage the Journal you destroy the head.
It's far cheaper to replace the cams than it is to replace the head. That's the idea.

wrote on 18 Oct 2017, 14:03 last edited by Calum@declan I can't see how your linkage could not have bearings lol. It would be horrendously slack and would never get an MOT.
As I said, if by some strange event you don't have any bearings there, you will destroy the part and it'll cost you £105 for a new linkage rather than the £10 for the bearings.
That's the point I'm trying to make.
I personally don't understand the mentality of scrimping.
I bought my car 3 years ago and it has been absolutely neglected. Whilst I do really need this car, I haven't driven it until everything has been rectified. We're talking everything, the car has simply sat still. I actually cycle everywhere lol, it's pretty tragic. So I understand having the lack of funds, but the way I see it, it will cost more in the long run if you don't sort it out.

Yeah yeah that's sound. That's the bronze bush. But the other part of the linkage, will have bearings in it.
That collar sits inside the bronze bush, the two should be replaced at the same time. I would polish the collar, and pack the linkage full of grease.

@calum can’t get the other one out can move it a bit but that’s it I’ll have a go from the other side tomorrow as it must be as dry as the Desert
wrote on 18 Oct 2017, 15:53 last edited by@declan Oh, I would probably leave the bronze inserts in there bud.
So long as the collars have not up and down play then that's fine. Just grease it all up.
Those bronze collars will wear rather than the linkage.
Once they have worn past their limit, the collar and bush will have play. But the outer side of the bronze bush should be fine. WHich means the linkage should be find

@finnerz89 Nah not in that part. It's the part that sandwiches between the frame that has the needle bearings. It's just a collar on the bronze bush for the bit declan is working with.

@calum so the bearing are up at the engine side I wanted to get em out but the bolt is too hard to get to it moves smoothly enough though so I think it’s fine

They poooorroopperly seize in their.
The trick is to soak that part for at least a good 24 hours.
And then on reassembly, grease the balls off it.
That part always seizes as there is not grease nipple IIRC.
But yeah that's a good one to replace as it's going to exhibit the most stress.

@declan Nah, the main ones have grease nipples on. Blame poor owners who don't bother looking after them.
Ultimately it's likely they've never been removed, or properly serviced, it's a miracle they've survived that long.
