Gearbox Lubrication

The gearbox should be full (18 ounces) 0.54 liters and not require additional lubricant unless the box is cracked or a seal is leaking. It is recommended that the 1/8” oil level plug (Figure MntP-R-0009)be removed after every 10 hours of operation. If required, oil should be added until it runs out hole.Check the oil level after operating long enough for warmed oil to flow through the Bearings into the lower Gearbox cavity. Refill to the test plug level. Check the oil again before operation, after every 40 hours of mowing, and at the beginning and end of each mowing season.

Recommended lubricant is Multi-Purpose Gear Oil P/N 00786250. Gearbox capacity is 1 Quart.

NOTE: Make sure mower is level when checking oil in the gearbox.

NOTE: Overfilling of Gearbox will cause pressure to build up and cause Grease Seals to leak.ATTENTION: If the Gearbox suddenly starts making an unusual noise, stop at once, check for leaks, and refill Gearbox as required.

DRIVELINE LUBRICATION

Grease Fittings are located on the Cross Assembly of each U-Joint and on the telescoping tubes. Grease the U-Joint after each 8 hours of use. Figure MntP-R-0021.Do not force grease through the Needle Cup Assemblies. Grease the telescoping tubes after every 8 hours use. To grease profile tube, disconnect drive from PTO and pull halves apart. Pump grease into outer profile tube and reinstall together. Lube Slide Collar weekly with WD40 or equivalent weight oil. Figure Mnt-R- 0037.

The Driveline Integral Shields should not become dented or otherwise damaged. The Integral Shield Assembly has a Nylon Bearing at each end and should turn freely. This nylon bearing should require lubrication every 40 hours. To remove the Integral Shields for replacement or repair, turn the three Nylon Nuts 1/4 turn in the Shield Slots of the Cone and Tube and remove them. Slip the Shield Cone Assembly off inner section of the Driveline. Install the new or repaired Shield on the Driveline. Place the split Nylon Bearing over the Driveline Housing of Shaft against the Yoke and in the Bearing groove. Install shield over the Housing so the Nylon Bearing fits into the Shield Bearing Retainer. Align a slot in the Shield Cone with one of the slots in the Shield. Put one of the Nylon Nuts back in through the aligned slots and turn until it is perpendicular to the slots. Add the other two Nylon Nuts.

Make certain that the Driveline Integral Shields are free to telescope and rotate around the driveline without binding.
