Shoulder surgery 10 weeks ago put the Martin SuperScooter out to pasture ... but finally riding again. A few weeks earlier than Doc permits, but what the heck. And it's been in the low  's last 2 days, impossible weather to pass up! SOOO nice to be back in the saddle! |

Hahahaha. You're mocking me, P-Guy! I need a safe space!
Yeah, this operation (it's the 2nd time - did it a decade ago and promptly wacked the thing 4 months later) isn't very painful but recovery is sloooooow. Trying to be a good boy this time and follow orders. Which for me is like a pig trying to fly.
Am not "supposed" to be using the left arm yet, but .... :
So the scooter sat for a while and one of my high tech pton seals has developed a weep. It's the case seal on the right side, behind the flywheel. Probably the easiest one to get to, thankfully. Slight weep - but it bets me homicidal every morning when I go out and there is that little wet spot on the floor. Damned thing has no manners or couth.
I have a flywheel puller. Any other special tools needed to remove that case part?

Request for advice:
So my scooter sat for a while and one of the super high-tech Vton seals developed a "weep". Making this a little more challenging, I'm still sort of working with only 1 arm (surgery on the left shoulder), so I'd appreciate knowing clearly about what's involved in removing the cover before starting.
The cover is on the right, behind the flywheel. I've removed the flywheel and stator on this engine, so I know that. But I've not gone beyond the stator. Looks like just 1/2 dozen bolts and the cover comes off - but with only 1 wing to work with, better ask ahead of time
Is there anything else I should know about before launching into this?

I use a socket to tap out the seal. It would be a challenge with one hand.

Hi John!
But actually removing the cover ...
Once the flywheel and stator are off, it's just a matter of unscrewing 1/2 dozen 8mm bolts ... right? Maybe some fumbling with the gasket when putting it back together.
Other than the seal removal itself - is there anything hidden or is it as simple as I suspect?
Oh yeah - have to dig out the woodruff key

A little late, but here are procedures and pix of replacing the leaking right side seal (a simple, 1-hour job): 1. Drop exhaust manifold, remove fan cover  2. Drain oil  3. Remove fan & flywheel (special tool needed to remove flywheel). First remove the nut (use your Harbor Freight electric impact wrench). THEN MAKE SURE YOU REMOVE THE WASHER BEHIND THE NUT. Screw the special tool into the flywheel (reverse threads, unless I'm mistaken), screw down the plunger and the flywheel pops off.  4. Remove stator and ignition pickup. Here is the right side cover ready to remove, bolts circled. Keep track of which bolt goes into which hole as they are different lengths:  5. Here is the leaky seal. No apparent damage, but that sucker didn't want to do it's job! Just bang it out with a socket and hammer - comes out easily.  6. New seal gets gently "banged" in with a socket that is small enough to fit in the housing, but not so small it fails to push against the shoulder of the seal. The seal installs on the right side cover from the inside.  7. New gasket. Right side cover back on; tighten all 6 or 7 bolts. Put stator and pickup back on. Put stator back on crankshaft making sure the woodruf key in the shaft is aligned with the slot in the flywheel. Drift the flywheel into place with a socket and hammer, hitting the socket gently. Washer on the extended part of the crankshaft, locktight, nut. Tighten with your H.F. electric impact wrench (NOTE: DON'T USE AN AIR POWERED IMPACT WRENCH AS IT IS TOO POWERFUL AND CAN DAMAGE THE CRANKSHAFT!!)  8. Install fan & fan cover. Add oil. Replace exhaust manifold. Have a beer. |

Its always a good idea to put a little coating of locktite around the seal shoulder so it cant leak in that spot.
Nice step by step bro!
