METHOD FOR CHECKING IDLER OIL LEVEL
WARNING
When the oil level is low and new oil must be added, the machine body needs to be inclined, and that is
dangerous.
Ask your Komatsu distributor for addition.
Low oil level in the idler can cause noise and seizure. Stop the machine on a flat place and check for the oil
level according to the following procedure.
1.
Remove bolts (1).
2.
Remove guide plate (2) and shim (3).
Keep removed shim (3) in a safe place and be careful not
to lose it.
3.
Loosen plug (4) gradually and check that oil oozes out
through the thread portion.
• When oil oozes out through thread portion
You do not need to add oil.
• When no oil oozes out through thread portion
The oil is insufficient. Ask your Komatsu distributor for
adding.
4.
After checking, tighten plug (4).
5.
Install guide plate (2) and shim (3).
6.
Install bolts (1).
REMARK
When installing guide plate (2), install the same number and thickness of shims as removed shims (3).
The optimum condition may be obtained, if the clearance of the idler is adjusted at the same time. For the ad-
justment method, see “METHOD FOR ADJUSTING IDLER CLEARANCE (4-28)”.
