Cleaned the rear shock up (Showa GD022) not looking at any major refurb only done 12k but the lower pivot bush seems a bot loose - has anyone replaced these? Would appreciate some idea of how to get them out (don't want to start hammering them out if there is a trick to it) and where is the best place for spares. Cheers, Gaz.
Ok I will talk to myself. On further inspection I think the lower pivot was a bit loose because one of the seal was missing. I was a bit concerned about this bearing because on giving it a spray to clean it a bit of rusty coloured stuff dripped out. Anyway, I picked the remaining seal out with a bent paper clip and the spherical plain bearing was free to move loosely. Again on closer inspection the spherical bearing was held in by a round section 'C' shaped retaining clip on either side so don't try to hammer it out at this stage. Also there is a top hat reducing bush pressed in from either side, I think at this stage the thing to do is remove the top hat bushes and gain a bit more room the get the spring clips out, that's the next step. I have found from another wed site (give them a bit of credit DuN) the bearing code is SB12A (IKO), also other ref could be GEF12EF from ixin web site - 22 od - 12 id - 9 o/housing - 11 o/ball. It is NOT a GE12. Suppliers are Mainline Bearings - Leeds & Autosport and Motorsport Bearings from ABC Autosport bearings and components - Mainline a bit cheaper £11 ea but depends I suppose where you live and postage. Will let you know what happened with top hat removal. Cheers Gaz.
Sorry no-one replied Gaz, I was hoping someone else would with a 'fresher memory'. It is quite common for this bearing to develop play and you are right the two top hat bushes need carefully drifting out to get access to the bearing. Some bearings are retained by 3 ball peens around the housing periphery and so are quite difficult to remove but possibly some are retained by circlip. It could be worth searching on Ducati.ms if no-one more knowledgeable answers on here.
Only joking. I am lucky mine seems to be the wire spring retaing clip. I the middle of the bore where the two top hat bushes come together there seems to be a groove made where they don't quite meet so I think the way to go is fettle a bit of a tool up to knock these out from the centre of the bore. Still trying to find supplier of the square section seals either side the spherical plain bush. Will check Ducati.ms. Cheers Gaz.
In the end pretty simples. Removed seals by bending a paper clip 90 degree about 3mm from the end, slipped it down the back of the bush and hooked them out. Removed the reducing bushes by grinding a bit if 10mm bar down and managed to get it in the groove where the two bushes come together in the middle of the bore and knocked one side out. I did round the sharp edge off a few times but kept regrinding so it fitted into groove. Then when one was out, knock the other out with a piece of 12mm bar. Removing the bushes gave better access to the wire spring retainers. Had no joy whatsoever trying to pick them out at the end. What I came up with that worked a treat was put a 0.15mm feeler gauge between the wire clip and the groove side wall - near the end - and hooked it out. I found that you could get the feeler gauge in one groove but not the other. I think this was because the bearing was pressed up against it. So do the side you can get out and then press the bearing away from the other clip so it is not pushing it against the side of the groove. Then pressed the bearings out using a socket or whatever you can find that fits. See pictures - Still got to find some square section seals - will let you know when I find them. Cheers Gaz
You prob didnt get many replies cos its a useless shock, so most ppl replace it. Its too short anyway.
Now you tell me. Secondly I want to keep it original, firstly I haven't got a few hundred £ to splash around. My be one day when I learn to push to bike to the limit. Cheers Gaz.
900ssie shock, it's longer by 5mm eye to eye. Or after market, Nog supplies a good wilber shock for the carby SS
ahh, I have the ie shock, because I have an ie!!!!! Was gonna say, I hadn't noticed any issues with the rear shock (other than the slight play in the lower mounting...)
The shock of an ie works very well at quickening up the stearing but not so much that you'll fall off at the first corner you come to
