TRANSMISSION POWER TAKEOFF LEAKS OIL CAUTION • When replacing gaskets between power takeoff and transmission housing, replace with exact number of gaskets removed. Failure to use the correct number of new gaskets will affect power takeoff to transmission gears spacing and gear backlash. With incorrect gear backlash, equipment may be damaged. • When power takeoff requires bearing or gear replacement, transmission must be removed in order to adjust power takeoff gear and transmission gear backlash. Failure to adjust backlash may result in damage to equipment. Determine oil leak location. 1. If power takeoff cover gasket is leaking, replace gasket (WP 0349 00). 2. If power takeoff shifter shaft seal, rear output shaft seal, input shaft seal, rear output shaft housing gasket, or input shaft bearing cover gasket is leaking oil, remove power takeoff from transmission and replace defective parts (WP 0349 00). 3. If power takeoff gears or bearings require replacement, remove transmission (WP 0131 00). Remove power takeoff from transmission and replace (WP 0349 00) or repair (WP 0464 00). 4. TRANSFER POWER TAKEOFF LEAKS OIL Check oil feed line between transfer case and power takeoff for loose fittings or damaged line (WP 0348 00). 1. If oil line fittings are loose, tighten. If damaged, replace (WP 0138 00 and WP 0348 00). 2. If gaskets or seals on power takeoff are leaking, replace gaskets or seals (WP 0348 00). Table 9.
