After performing throttle free play adjustment, check
the oil pump cable adjustment as described in this section.
Oil Pump Adjustment
The oil pump injects lubricating oil into the engine.
Throttle position determines the amount of oil injected.
Control cable adjustment is necessary because cables
wear and stretch during normal use. Incorrect cable ad-
justment can cause too little or too much oil and cause en-
gine seizure and poor performance.
NOTE
Before checking or adjusting the oil pump
cable, check and, i f necessary, adjust the
throttle cable free play.
Check the oil pump cable adjustment seasonally or
whenever the oil pump cable is disconnected or replaced.
1. Open the shroud and secure it in the open position.

Figure 17) then rotate the adjuster (B). Tighten the jam
nut after obtaining the correct dimension.

sembly for proper play and adjustment. Perform the fol-
lowing:
1. Support the snowmobile so the skis are off of the
ground.
