I am glad to hear it worked out. I agree, we may need to replace the slave
at a future date but I have two years on a similar rebuild so far without a
problem.
I am going to have to buy one of those Mytevacs, twenty minutes to my two
days, yikes!

Subject: Clutch slave rebuild update
The clutch slave rebuild was a success. I saved some coin by just
replacing the piston and dust seals. They were about $15 as opposed to
$61 for new slave (barring any discounts, that is). I can see that part
needing replacement in time. I removed the majority of the scoring on
the cylinder wall with a fine polish. There also was some oxidation on
the inner lip of the cylinder. I took a few swipes to it with 1500
grit, just enough to remove the oxidation. It all went together easy
enough. I had to take another trip back to the parts store to get a new
brass gasket that fits in the recess of the slave casing in between the
sleeve. I first tried to reuse the original but it developed a leak
from that spot. This gasket is Yamaha part # 90430-10171-00. If you're
going to take that sleeve off for any reason, I recommend replacing that
gasket. It's about a $1.50. The replacement gasket was a tad bit
larger in diameter than the one I took off so when you replace it, make
sure it is concentrically aligned with the case recess and the sleeve
before you torque it down. It will seat properly and form a good seal.
While I was at it, I also replace the gaskets on each side of the banjo
bolt which attaches to the sleeve. After about 20 minutes with the
Mityvac, I had the system refilled. The clutch operates much better now
and there aren't any leaks as of yet. No leaks from the hydraulic
system that is. I do have some drippage from the case cover. I didn't
replace the side case gasket because it did come off in one piece and
was pretty firmly attached to the case cover. It takes some work to
remove gaskets so firmly attached. If the drip continues, I'll replace
that gasket as well.
Sure feels good having the Max back on the road again. Polished scoops
to boot! Since I had the MC cover off, I mounted it to a 2x4 with
smaller countersunk screws and filed off all the American and Japanese
verbiage. Since the word YAMAHA is even further recessed, it remained
intact. I went through the same sanding/buffing/polishing ritual on
both of them and they now look like the MC covers offered by Holeshot
without the $60.00 cost. The only cost was the sandpaper and the labor
to do it. Plus there's the pride in doing the work yourself.
That's if for now,
Vmaxman
