Speed-Change Box
The speed-change gearbox is lubricated and sealed at
the factory. Under normal conditions, it does not require
maintenance or lubrication.
If you open the gearbox for repair, repack all gears and
around the shaft bearings with least 7 ounces of lithium-
based, wheel-bearing grease.
It is important to keep moisture and dirt out of the gear-
box. Inspect the rubber seals on the gearbox drive and
shifter shafts. Replace seals if necessary.
Before bolting them back together, spread a very thin
coat of anaerobic sealant (such as Loctite 525) on the
gearcase-mating surfaces.
IMPORTANT: Use sealant sparingly! Excess sealant
may squeeze off surface and lock bearings or gears.
