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 gear
lube (Great Plains part number 788067).
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
gear case mating surfaces.
IMPORTANT: Use sealant sparingly! Excess seal-
ant may squeeze off surface and lock bearings or
gears.
