Routine Maintenance
Check Oil Level The oil level should be checked daily and corrected if necessary. Method The oil level must be checked with the engine idling and with the transmission oil cold. Withdraw the Dipstick [ C ] wipe clean and reinsert into the dipstick tube. In this condition the oil level should fall between the Max and Min marks on the dipstick. At normal operating temperature, (800C) the oil level will rise to 20- 30 mm above the maximum mark on the dipstick. Do not overfill the transmission as this may result in oil breakdown due to excessive heat and aeration from the churning action of the gears. Early breakdown of the oil will result in heavy sludge deposits that block oil ports and build up on splines and bearings. Overfilling may also cause oil leaks. Change Oil An initial oil change and flush is recommended after the transmission is placed in actual service. This change should be made at any time following 50 hours in service, but should not exceed 100 hours. An oil change and flush should be scheduled for every subsequent 1000 hours of operation. When changing the oil it is essential to renew the oil filter
Method Place a suitable container beneath the Oil drain plug [ A ], loosen the plug and drain the oil from the transmission. Examine the plug for any visible debris. Replace the plug and refill the transmission with the correct oil quantity through the filler found beneath the breather [ C ] Check the Oil level as above.
