The 633 you had that failed after a long high speed run, could you tell what failed first or was it pretty hard to tell afterwards? Just wondering for my own machine as I was planning on doing some long range running. Maybe some sort of pump and oil cooler setup would be a help? You'd think they would keep on going though as long as they were filled with oil. I went about 4-5 miles with mine non stop at around 17-19mph but probably not much farther than that. It was fairly hot and kicked a little oil out but no serious issues that I know of.

We ran a 26 mile loop. Probably 20 of that was 3rd hi full throttle
20ish mph.

I litterly wore through the brass bushings in the axle tube and into the housing

I do remember mine were fairly hot to touch after going a few miles.

I suppose it wouldn't be too hard to drill and tap some holes in the top of the axle tubes and then pressure feed both sides. Maybe with a normal gear driven automotive oil pump running off the axle or something. If you had decent enough size lines so it would flow. Probably would keep them a lot cooler too. Wouldn't need a lot of pressure I wouldn't think, just a bit.

I guess the other gears and shafts make out ok with the needle bearings.
