Power End
Checking Power End Oil Level
The most accurate method to check the oil is when
the unit is on level ground and has not been in use
for 5 to 8 hours. If the pump has been in use and the
oil needs to be checked refer to the alternate meth-
ods as outlined in “Alternate Oil Check Methods”
following this procedure.
Note:
Because of varying factors such as tem-
perature, the oil in the pump will com -
pletely settle between 5 and 8 hours.
1. Locate the sight gauge (Figure 97) on the back
of the power end case. With the pump off (for 5
to 8 hours), the oil should be at the Full level.
2. If the reservoir is low, add 80W/90 detergent
free gear oil while the engine is off. Remove
the fill plug and add oil through the port in the
back plate.
Alternate Oil Check Methods
Method 1: If the pump is at or near operating
temperature and needs to be stopped during
operation for purposes of checking the oil, stop
the pump, wait 1-2 minutes and check the sight
gauge. As long as oil is visible in the gauge, the
oil level is acceptable. If oil needs to be added,
add 80W/90 detergent free gear oil while the
engine is off. Remove the fill plug and add oil
through the port.
Method 2: If the pump has been run recently,
but it is not known how long it has been standing
idle, the oil level can still be reliably checked. With
the unit on level ground and the engine running
at slow speed, engage the PTO so the pump
turns over slowly for 10-15 seconds. Disengage
the PTO. Check the oil-level at the site gauge. If
the oil level is still visible in the gauge, there is
sufficient oil in the crankcase to run the pump.
Optimally, the level should be halfway between
the bottom of the site glass and the ADD line.
!
CAUTION
Under no circumstances should you operate
the pump if there is no oil visible in the sight
gauge at rest no matter what method is used to
check the oil level.
