Shoshin---"not that's it's happened to me!!!!" of course not--it was a friend--but yea--I agree with all here--a complete oil change (motor and transfer case)should take about 30-45 minutes--unless you decide to sit back and admire this great piece of machinery--that could add on about 30 minutes---then go RIDE!!!!!!! VROOM VROOM!!!!

The transfer case is just that .... there area two gears connected by a chain ... that's it. The oil in the transfer case baths the bottom part of the chain.
The tranfer case tranfers the rotational energy from the transmission to the front pulley through the chain.
The transmision does the shifting and is connected to the tranfer case by a shaft. The oil in the transmission is not shared with the oil transfer case.
DocNicely put there Doc. Man there is always something to learn here no matter what your skill level.  Lone*Road*

I went out and did mine after reading the forum posts. Started the drain, went in and had breakfast, came back out and put the plugs back in and filled her up. I have V & H longshots on a 2000 RS and did not have to pull them off. The drain plug was easy and the check level was as well with a short allen wrench. The Fill plug came out fine with a long flat bladed screwdriver.

I got ya Doc, you can see right into the T case and I can see how it works i did take a look at the service Man. But what I am saying is maybe the resistance is less with better lube and it allows the speed to match the gear better, like 'Floating the gears" on a truck.
Just try to figure why it shifts easier and quieter with new lube. Becauseit don't make sense.
your answer is; the slack in the chain drive causes the clunky shift.
chain drives, especially the way we beat on them are prone to stretch. the drive also runs the engine's oil pump assy.

Correct me if I'm wrong, but I thought the oil pump was driven off of the clutch pack on the left side, not off the transfer gear/chain on the right?

Oil pump for the transfer case is an isolated unit and not part of the engine.
GL-4 requirement would be valid if the transfer case had white metal bushings that could be corroded by older versions of GL-5 fluids, but to the best of my knowledge it does not. Some quality fluid manufacturers, including Amsoil, have stated their GL-5 is non-corrosive, but for peace of mind Amsoil offers a full synthetic 75-90 gear lube with a GL-4 rating. I have a feeling that Yamaha is being proprietory in specifying their GL-4 - it's all they've ever supplied. I haven't seen any on a dealer's shelf for years.

Shoshin, do a search for the service manual, I'd post it for ya but it's against company policy..  the oil pump for the engine is driven by the primary shaft which is accessable thru the transfer case, the transfer case itself does not have it's own oil pump, it is just a bath..  |
