Pump drive
|
It is advisable (and easier) to replace the alternator belt along with the air conditioning compressor drive belt when the camshaft drive belt is replaced every 600 hrs. Using an underbody crop sheet for late-season row crop work will help to prolong the life of the belts and the alternator.
Air conditioning compressor drive belt. 1. Slacken the centre retaining bolt on the jockey pulley eccentric. 2. Rotate the eccentric to tension the belt. 3. Retighten the centre bolt. NB - Do not overtighten the belt.
Hydraulic pump drive. The hydraulic pump is driven by a propeller shaft connected to the front engine crankshaft pulley. This shaft should be greased weekly or every 50 operating hours. There are 3 grease nipples on the shaft - one on each universal joint and one on the centre sliding section. One end of this shaft will have to be removed to replace any of the drive belts. It is recommended, and is in fact easier, to disconnect this from the hydraulic pump end. Take care not to pull the two shaft halves apart - If you do so it must be put back together in exactly the same position to ensure it stays in balance. (Each half is marked with a series of centre punch marks to indicate correct position) |
