Checking Oil Level
The oil level in the transmission must be checked before each use. Procedure
for checking oil is as follows:
1. Visually inspect the transmission, converter and drive line for security of
mounting. Inspect plumbing and electrical components for security of
attachment and/or leaks. Leakage must be corrected.
2. Oil level check: It is best to check the oil level after the oil well fracturing
rig has been parked with the engine not running for at least 8 hours (or
overnight). The fracturing rig should be parked on a level surface.
a. With the engine not running, the low level sight gauge should show
full, and the hot oil level sight gauge may be full. Add oil if the low
level sight gauge does not show full.
b. Start the engine. With the engine at low idle for 1 minute, the
transmission in neutral, and with cold oil (10~35
o
C) the oil level
should be visible in the low level (lower) sight gauge. Add oil as
necessary until it is seen in the low level sight gauge before
operating the oil well fracturing rig. Note that there is a low oil
level sight gauge on the front of the transmission by the hot oil
level sight gauge, and one on the rear of the transmission.
c. If the oil temperature is at operating temperature (80~100 o C),
the oil level can be checked. With the engine at low idle for 5
minutes, the transmission in neutral, the low level sight gauge
should be completely full and the hot oil level sight gauge should
show 1/4 to 1/2 full.
The oil level should never be above the
middle of the hot oil level sight gauge . Any oil level
adjustments must be confirmed with a cold oil level check as
previously described.
d. If a sump heater is used when the fracturing rig is parked, the oil
temperature after the engine is idling for one minute will determine
which of the above procedures should be followed.
Do not operate the transmission with oil levels above or below the
recommended settings. Either condition can result in overheating or
loss of power and damage to the equipment. When following this oil
check procedure be sure the fracturing rig is secured from moving.
