Re: Yanmar 2QM15 Service Manual FREE!
Great engine. Great service manual.
KBW-10 on my 40 yo 2QM15 started slipping badly in August. Tried to find a replacement. Found a couple on line for a bit under $3K USD. Tried to find a mechanic who would fix it...$1-1.5 USD plus shipping.
Decided to tear into using the manual as a guide last week. Was able to get it disassembled without the special tools the manual called for. As expected, I found the sintered copper and steel plates in the clutches worn. Ordered them and new needle bearings, a bushing, oil seal, o-ring, a shim set...$590 delivered...arriving next week.
Gotta get a special tool built by the local machine shop (Yanmar wants $220 for the tool) this week.
Then I'll put it back together.
I'm not a mechanic, but I can read a good book, and that manual is a good book.
Love that engine. It should last another 20 years.
