YOU ARE BUYING BEAST UPGRADE 7: 
# Nylon Gear Set 
Please lubricate on installation 
# Best practice to do the bearings when you install the gears.

Any stripping of gears will be from incorrect installation of gears or other parts or a failure somewhere else. 
Please use new gearbox screws when installing and make are the gears are working correctly by found a manual rotation by hand. 
Make sure your plunger is nicely lubricated with correct oil. 
The most common problem with stripped gears is the 2 gearbox halves not screwed back together properly due to the original screws not holding. I've seen this happen a hundred times. Make sure there is zero gap between your gearbox halves and all screws tighten with a bite and they should tighten hard especially around the motor. When installing a motor make sure it sits right down into the half moon seat on the gearbox shell.
