7.4.1 Dismantling
The HS300 arrangement differs from the rest of the range because of the extra weight and bulk of the unit. It has an
external lifting bracket. This does not require removal for maintenance tasks such as wear plate, impeller or mechanical
seal replacement.
1. Disconnect and remove all hydraulic and discharge piping and the hydraulic motor from the pump.
2. Remove the two plugs (51) from the bearing and seal chambers and drain the oil.
