PUMP DRIVE (GEARBOX) LUBRICATION
The pump drive used on the APE power units has three areas that require lubrication. The
main gearbox takes about 84 ounces of oil. A gallon of oil is 128 ounces, so 88 ounces is just
under 3/4 gallon. Check the level using the dip stick. See item 1 for main pump drive reser-
voir.
The space between the hydraulic pump and the geardrive is not lubricated by the main reser-
voir. There is a small pipe plug (see item 2 & 3 above) mounted above each pump drive
output. Remove this plug and fill this area with 8 ounces of oil. Remember that both pump
drive output areas must be filled with 8 ounces of oil. The purpose of this oil is to lubricate the
pump shaft and the gear splines on the pump and gear.
The engine adapter must also be lubricated with 8 ounces of oil. This lubricates the main
engine shaft and adapter components.
Oil changes are suggested every six months or 1000 hours, which ever occurs first.
Fill with Mobil SHC 629. Before operating the unit, check the oil level dip stick.
