4. Clean the strainer in a suitable solvent.
5. Install the cleaned strainer and new gasket. Tighten the
strainer mounting bolts to a torque of 7.4 lb-ft. (10 Nm).
6. Remove the transmission oil filter by unscrewing it from
the transmission housing (Figure 6-41). Properly discard
the filter.
7. Coat the seal of the new filter with clean transmission oil.
8. Screw on the transmission filter until it touches the filter
head. Then, turn the filter another 3/4 of a turn minimum
to seat the seal.
9. Fill the transmission with Mobil ATF 210, or equivalent,
transmission fluid to the upper mark on the dipstick
(approximately 3.43 gallons [13 liters]).
10. Start the engine and let it run at idle speed for a period
not exceeding five minutes. This allows the oil to fill the
transmission filter, torque converter and hoses.
11. Stop the engine, wait approximately one minute and
then check oil level. If low, add oil to the upper mark on
the transmission dipstick. DO NOT OVERFILL.
Replace the Axle Housing Lubricant
NOTE: It is necessary to climb under the crane to drain the
axle housing lube. Be sure engine is shut off, the
ignition key is removed and chock blocks are in
place before climbing under the crane.
1. Clean around the fill plug in the axle housing
(Figure 6-42 and Figure 6-43). Remove the plug.
2. Place a container under the axle housing drain plug
(Figure 6-45 and Figure 6-46). Remove the drain plug
and drain the fluid into the container. Install the drain
plug.
3. Clean the front axle breather (Figure 6-44) with a
suitable solvent. If the breather is removed, be sure that
the hole in the breather tube is facing toward the axle
hub (toward the right).
