Hydraulic pump belt
The hydraulic pump is driven by one Syncronous Belt. The belt can be tensioned by adjusting the pump
mounting plate.
1. Loosen the four M8 locking bolts which bolt the pump mounting plate to the engine mounting.
2. Pull the pump downwards to remove any slack in the belt. This belt drive does not require any
tension due to the type of belt.
3. After the belt is tensioned correctly tighten locking bolts.
If a belt change becomes necessary because the belt is worn out, loosen pump mounting locking bolts so
the belt becomes loose. Remove the drive belts, then replace the pump belt. The belt size is Syncronous
Belt (880-8Mgt-20 Belt).
Greasing Bearings & Pivot Points
1. Two bearings on the rotor shaft, one under the engine cover and the other above the inlet opening.
2. Two bearings on the feed wheel.
3. Two bearings on either side of the feed wheel pivot.
4. Outlet chute swivel, two grease nipples.
5. Two grease nipples on the engine engagement screw.
Hydraulic System
Replace oil filter after first 50 hours, then every 500 hours.
If the hydraulic oil should be changed every 800 hours. It is a closed system therefore it should not become
contaminated, however if contamination is detected oil should be changed. Use only a good quality brand,
32 grade hydraulic oil. Fill the hydraulic oil tank so that the oil level is approximately 5-10mm above the
bottom of the filler cap sieve.
A double crossover relief valve is fitted between the pump and the hydraulic motor. This valve is present for
a maximum working pressure of 2000 PSI.
For any repair in the hydraulic system, contact Hansa Products or seek advice from a competent service
agent.
