hoot gearbox oil level?

linnix13 · #1 11-09-2009, 11:29 AM

when i got my kit it had alot of oil in the gearbox, i filled it up through the filler, but the clutch slips bad!

im going to drain all the oil out when i get home because im sure this is why its slipping, exactly what amount should i put in there from empty? thanks!

the Hoot gearbox is similiar to the Grubee 4 stroke box and most users who are having
success with it are using grease.

Apparently there are two completely different Hoot boxes, one with chain and one with gears. The gear version definitely uses grease but if the chain version has a filler it probably requires oil. To add to the confusion there are Grubee with a belt. It would be nice if someone around here actually had some credible info on these.

Yes, like maybe the seller?

What do the instructions say?
What does the dealer say? If he is offering a warranty, I would only hope he would know.

I am assuming it's a gear box, and not a chain reduction, yes?
There is a filler plug, right? No dip stick? Nothing in the instructions about type or amount of lubricant?

If it has gears, one would assume from most other gearboxes of all types to use a liquid lube such as ATF (Mazda 5 speeds, for one) or 80w90 or other gear lube (most low speed gear boxes).

If it has a chain, straight 50wt or 70 wt should work.

Now about that clutch, is it supposed to be a wet clutch or a dry clutch? How can it be a dry clutch if it's in the box with all the lube, no matter what you are supposed to use?

If it is supposed to be a dry clutch and run above the oil level, what happens when one leans the bike or climbs a hill? Could it be that this reduction unit was supposed to be used in a stationary application?

I ask these questions as an "open forum" way of figuring this out.

BTW- is this a centrifugal clutch (automatic)? It is supposed to slip somewhat if it is, that's how they work.

A couple 4 stroke kit sellers I emailed did not respond and to be honest these guys seem to know less than the customers. 4 of the kits I bought were liquidation and no instructions. 2 were surplus from Duane and I don't think he expected me to get out of the driveway with those gearboxes. He implied as much. Anyway these things were half price and worth it just for the HS.

Most of the info and assembly instructions for these comes from this forum. Mostly warnings about slipping due to too much grease.

BTW all 4 stroke kits are centrifugal/pull start.

i found that lithium grease was the best for not having the clutch slip but it broke down over time, i was curently testing heavy duty axle grease when i wrecked so once im better i will continue and see how that stuff holds up, but ive got my eyes open for a replacement gearbox, this one has held for now but i dont trust it
