Reinhoud Posted February 16, 2022 Share Posted February 16, 2022 (edited) Is there a trick / way to replace the crankshaft seal without unbolting the crankcases? And without damaging the seal? Thanks Edited February 17, 2022 by Reinhoud Quote Link to comment
Arttu Posted February 16, 2022 Share Posted February 16, 2022 Not sure about the GS1000 but I have done this with a GSX1100 successfully. I think I drilled a small hole on the old seal to pry it out. Then just carefully tapped in the new one. Quote Link to comment

Getting it out is not too hard, but when tapping the new seal in the coating of the seal comes of real easy... Like these seals are more tight then other seals.. Quote Link to comment

How did you tap it in? https://www.cmsnl.com/suzuki-gsx1100-1983-d-general-export-united-kingdom-e01-e02_model13730/partslist/FIG-10.html https://www.cmsnl.com/suzuki-gs1000-1979-n-general-export-e01_model13512/partslist/FIG-08.html Quote Link to comment
Reinhoud Posted February 16, 2022 Author Share Posted February 16, 2022 Might have solved the problem. Haven't taken it for a ride yet, but so far it looks good. Made a tool so I can "press" it by using the crankshaft. Lot of grease around the seal. Still looks like the rubber is stripped off of the seal, but a lot less. 3 Quote Link to comment

Can't remember exactly, it was few years back... Btw, are you sure you have it there right way around? That was the reason why I had to take mine out. Quote Link to comment

Arttu Posted February 16, 2022 Share Posted February 16, 2022 I think it should be other way around but unfortunately I can't remember where I checked it from. Even the workshop manual doesn't tell that clearly. But for example in this picture it probably is other way around. If you take a close look on the seal you can see the lips are different compared to normal oil seals. Mine was weeping slightly when mounted wrong way. But if your's doesn't leak then there shouldn't be anything to worry about. Quote Link to comment
Gixer1460 Posted February 16, 2022 Share Posted February 16, 2022 I just looked in the Haynes for the GSX1100 / 1150 and that shows the metal centre of the seal facing out ie. opposite to how it is above. Not sure how different the GS1000 would be, if at all! Quote Link to comment

Swiss Toni Posted February 16, 2022 Share Posted February 16, 2022 Most cases, the spring always goes towards the oil. 2 Quote Link to comment

Reinhoud Posted February 17, 2022 Author Share Posted February 17, 2022 It's not leaking anymore. I was in doubt about the way it should go in, with the metal side out there's also a bigger chamfer, and indeed, the spring is usually on the oil side.. 2 Quote Link to comment

Those small ridges on the seal face should lay against the crankshaft bearing. Then the seal is deep enough in the engine block. When installing the seal in the engine block, put slightly rtv-silicone on the outer edge of the seal. Quote Link to comment
Macam Posted February 19, 2022 Share Posted February 19, 2022 hi I’m new to this forum, just stripped this 2 weeks ago the engine hasn’t been stripped before and that’s as it came out of the casing, hope it’s some help (it’s a gs1000 1982) 2 Quote Link to comment
TonyGee Posted February 19, 2022 Share Posted February 19, 2022 (edited) that seems strange ? i thought the 4 raised bits on the seal would go against the bearing !!!!! looking on the parts diagram though it looks right Edited February 19, 2022 by TonyGee Quote Link to comment
