Generator trailer

[Grant-53]

I sold auto parts for about fifteen years. Tapered roller bearings, good grease, and double lip seals work great. Grade 5 bolts (three marks on the head) were good enough for most things. Grade 8 (six marks) are high strength alloy steel. Metric bolts seem to come in a similar high strength spec.

When I bought that trailer the bearings and spindles were done. That was one of the first things I did was replace the axle, used US made bearings not Chinese garbage and marine use gtease seals. I was using a lithium complex highly fortified MoS2 high temp axle bearing grease, but now I use normal lithium grease, which i think is actually better, the oil doesn't run out as quickly.

Hah, I'm unlikely to repack bearings every decade...

Which reminds me, my jetski trailer sure is noisy on the road. I have never checked the bearings, and I bought it 8 years ago from a friend who also didn't check them.
