Wheel Bearing Maintenance Question

[WISDAN]

I believe wheel bearing service yearly would be fine, maybe a little over kill but a good opportunity to clean and inspect for wear or damage and also gives a chance to check the main gear with the weight off the wheels.

I remember way back in 1998 when I purchased my model 3. The previous owner supplied along with all the other paperwork, a Denney Aerocraft conditional inspection checklist that included main wheel bearings to be inspected and re-greased at each conditional. I've always followed that recommendation. You also get to check your axles and brakes at the same time.

I do mine almost every year, and they never need it. I never do my trailer
wheels and they always need it, yet I've never killed a bearing ...

Jeff

Those "big rocks and bent props" guys that land on the water with the big tires then roll up on a sand bars, may need to inspect and grease more often.

...or if you run wheel skis in the snow.

IMO, I still think an annual inspection (at least) is easy and prudent.

Interesting thread, I am at 360 hrs and have not done mine since original build. Are there others going longer intervals than annuals? I was thinking 500 hrs seemed like a good idea. I have had no issues with my wheels (not that that is a good measure given we want to find thing before they happen).

I do every other year for a repack. Worked fine on my RV for 5 years and has worked fine on the Kitfox. I keep my plane in a hanger out of the weather as well if that matters (to wheel bearings). Even after two years the grease is not very dark.

Thanks for the input, I will repack next annual and see what I find
