Bearings And Seals
Great deal, Great service.

Bearings and seals.
I took my bg86 blower apart to clean it and noticed oil everywhere from the crank seals leaking So I got this kit and it was all a perfect. One of my stock bearings sounded pretty rough. I would definitely buy this kit again if needed.
-
Bearings worked but would be better if the inner race was the same as the original
Although the inner race was different from the original it was noted in the product description. That was helpful to know.

Check Fitment Before Installing!
These bearings & seals are very nice, a step above the Chinese stuff on eBay & come with assembly grease (a nice touch). A fitment note needs to be added to the description though. SOME Stihl engines use a bearing with a slightly wider inner race. These ProLine bearings are "normal", the inner & outer races are the same width. Check this out when you remove your old bearings. Some cranks have a small shelf (normal bearing) for the bearing to sit on & some do not (wider inner race). On cranks with no shelf DO NOT press these bearing fully home or they will rub on the counterweight & the assembly will be too narrow for the case. Use a spacer or don't press fully against the crank.
