After 5 hours I finished my first experience with my NOS 2013 Burgman 400's CVT.....cleaning, deglazing & installing an 18g set of Dr P. sliders and pieces. 10 mos & 4,200 miles
The cheap 12V Harbor Freight impact gun did
remove the 2 nuts w/no issues - using only a spare 12V scooter
Although I've faithfully cleaned the fan filter -there was a lot of sand/dirt and corrosion on the front end of the metal CVT cover - so I scrubbed and buffed it and painted with black high-temp paint.
The roller carrier had a tablespoon of fine black stuff....the dirty rollers were not flat spotted.
The pulleys had a fine groove low down. I cleaned them but did not disturb the surface.
Cleaning and painting took an hour or two - working with my new torque wrench took time. I made story marks on the nuts just in case.
Ran the engine before buttoning everything back up - & sure enough, the belt was pinched and the front nut came loose in seconds.
Oh yes, the new "not $5" O-ring worked great - perfect fit! (from the O-Ring Store)
Will take it for a first ride tomorrow, sunrise.
5 hours later....all buttoned up. Glad I bought a bag of those push/clip/rivets!
