90cc Rear axle Grease?
I just bought a monsoon 90cc atv(don't laugh) it's an older one and I got it for 200.00, and it runs great. My question is though there is no zerk on the rear axle like my other quads. Are you supposed to grease these axles and if so how??? Good thing about a cheap quad, if they break it no big deal.

90cc Rear axle Grease?

Many brands of mini-quad don't come with grease zerks in the common areas. They use either sealed bearings or recommend you replace non-sealed bearings / bushings when they wear out. While you're on a long trail and a major bearing blows, always ask youself "why don't do this simple mod at the factory"? From a proactive "save critical bearings & bushings" perspective, here's some info that may help....
To install a grease zerk in the rear hub, perform the following:
1 - With rear hub shield on, locate an easy access place to install a grease zerk. For example, - Press Here -
2 - Remove your rear axle and hub bearings.
3 - Remove the inner seals from the axle / hub bearings.
4 - With a spot marked in above step 1, drill a hole for grease zerk.
5 - Use a "push on" type grease zerk in the small hole. For example, - Press Here -
6 - Using an old rag, wipe away any drill shavings from inside the hub.
7 - Re-install rear axle and its axle bearings. Ensure the removed bearing seal side are facing inward. At this point in time, don't install the sprocket or the rear brake drum.
8 - Use a grease gun and install Wheel Bearing grease to approx 1/2 to 3/4 volume space. Any grease will do but I like wheel bearing grease the best. For my little grease gun, it took 70 squirts. The grease inside the hub will "settle" onto the removed inward size of the bearings. If grease comes out the bearings, wipe away. Especially on the brake drum side.
9 - Re-install the brake drum and sprocket with proper torque lbs.
10 - Away you go!!!!!
If you are doing to do this, you may want to install a grease fitting in its Swing Arm bar as well. For pictures to install this "should also be mandatory" grease zerk, surf pictures within: - Press Here -
Hope this helps....
