Service manuals/ Shop Manuals

service manuals for the 88 wr250 and a 77 cr125. I currently just have the parts list for both. I am about to do a complete rebuild on both Engines.

Check Husqvarna-parts. They sell your 77 service manual on cd (with a few other years lumped in). I don't know that the '88 engine manual is out 'in the wild'. But I believe most guys use the '86 manual that you can download a few places (Husqvarna outlet. Hva-factory, maybe others) for free. 86 and 88 engines share many parts.

Thanks!

I never used a manual beyond the owners for these bikes. On the other things I have dealt with the term I use is workshop manual, might be amusing to see if the terminology has changed over the years and continents or countries. If you are going to go official the interference fit of the bearing on the transmission input shaft, the clutch one with the snap ring bearing, that one most likely will always be loose. I do not know if the manual you desire has a fit spec. Most likely it would say replace the cases, it is a design problem especially with the magnesium and no steel insert like on the crank bearings. The bearing at the sprocket also might below a sensible interference fit. Depends on what a complete rebuild means.

on the 86 engine manual, they share most components in common, a few minor changes, such as a nut instead of a circlip at the clutch, 6 springs instead of 5
aside from some VERY minor differences the info still applies
