imago Posted April 8, 2022 Posted April 8, 2022 I pulled the top end off of a GSX1100 ET engine this morning to have a quick look at what's likely to be needed for a refresh. It was a running engine, with no faults or oddities, decent compression etc. However, there were no locator dowels between the barrels and crank case. The liners were 'snug' in the crank case, and as I said I know it was running just fine. Presumably they were left out at some past top end rebuild, but made me wonder just how necessary thos dowels actually are? Quote
bluedog59 Posted April 8, 2022 Posted April 8, 2022 It's one of those things, it may run fine but Suzuki don't go to the trouble of fitting them if they're not needed. I'd put a set in when you rebuild it. 1 Quote
TonyGee Posted April 8, 2022 Posted April 8, 2022 looking at the parts diagram their should be 2 of em !!!! Quote
imago Posted April 8, 2022 Author Posted April 8, 2022 It will definitely get them in on rebuild. I suppose it's a tolerance thing in that most would be OK without them, but to guarantee tolerances are met it's easier/cheaper to repeat the process for two dowels and their holes. Rather than it is for four holes in the crank case and the bases of four liners. Quote
