REGULAR INSPECTION AND ADJUSTMENTS

MAINTENANCE INTERVALS

The following schedule is intended as a general guide to maintenance and lubrication. Bear in mind that
such factors as weather, terrain, geographical location, and individual usage will alter the required main-
tenance and lubrication intervals. If you are a doubt as to what intervals to follow in maintaining and lu-
bricating your machine, consult your Yamaha dealer.

HYDROSTATIC TRANSMISSION

Check the condition of the hoses. It is of vital importance that there is no damage on the hoses, especially
important is the reinforcement mesh: no damaged cord is allowed.
Check for oil leaks (sweating) of all connections.
Every 5th hour check the status of the system. By use of the control button, under the reservoir, the nor-
mal position is out. If it is pressed in and doesn't come out again there can be two causes. Either the
charge pressure has dropped or oil has leaked out. In both cases bring the motorcycle to a Yamaha
Service Centre.
If the button hasn't been tested for a longer period it can be a little sticky, if so pull it in and out a couple
of times to lubricate the seal, then press it in again to make the function check.
Service
Every 20th hour:
– Change oil in the hydraulic motor reduction gear housing
– Change oil in the pump transmission housing
– Check the wear in the pump transmission.
The oil in the reduction gear housing is changed by taking the hydraulic motor from the shield.
The oil in the pump transmission is drained by taking off the lid. There is a filler plug on top of the trans-
mission housing.
WARNING
It is connected with danger to open the hydraulic transmission. That includes the plugs on the
Pump/Motor housing as well. The transmission comes filled and pressurized from the manufac-
turer.
