Hydraulic Starter System - General Maintenance
Starter System
 
Warning
It is imperative that skilled personnel be involved in the installation, operation, and maintenance of the starter system. Personnel should be familiar with how the equipment is to be used, the limitations of the system and its component parts, and have knowledge of good hydraulic practices in terms of safety, installation and maintenance.
 
Description
The hydraulic start system basically consists of:
1. Engine driven pump to charge the accumulators 2. Unloading valve to divert pump flow to the reservoir when system pressure is attained 3. Manual start control valve to direct oil from the accumulators to the starter motor 4. Starter motor to drive the starter mechanism The other items in the hydraulic start system are passive (ie: reservoir, accumulators, filters, etc.).
 
Storage
For short term storage, the best procedure is to have the reservoir full of oil.
For long term storage (indoor or outdoor), there are two alternatives:
- with the reservoir full of oil, remove the filler breather and seal the opening with a plate and gasket.
- with the reservoir empty, spray the inside of the reservoir with a rust inhibitor compound and seal the opening with a plate and gasket. Be certain the spray is directed into the corners and all sides of the reservoir.
The balance of the system should still be full of oil from the test procedure and will not require further attention.
 
Reservoir Filling
With the filler breather installed, fill the reservoir with hydraulic fluid using a filter cart to transfer the oil from drums or other sources. The filter cart should be equipped with a 10 micron absolute element (Beta 10 ratio of 75 or greater).
 
Warning: Do not fill the reservoir when the accumulators are filled with oil (fully charged).
 
Check the system pressure gauge to confirm it reads zero psi. When the accumulators are charged, the oil level in the reservoir should not be above the indicated level. If in doubt, discharge the accumulators using the starter bypass valve, then fill the reservoir to the full mark.
 
General Maintenance
Filter: The filter element should be changed every six months.
Reservoir: Maintain proper oil level at all times. See warning under Reservoir Filling.
Suggestions:
1. Setup a filter maintenance schedule and follow it diligently.
2. Do not return to the system any oil that has leaked out of the unit.
3. Always keep the supply of fresh fluid covered tightly.
4. Use clean containers, hose, and funnels when filling the reservoir. Use a filter cart when adding fluid to the reservoir.
5. Use common sense precautions to prevent entry of dirt into the reservoir and components that have been temporarily removed from the circuit.
6. Make sure that all clean out holes, filler caps, and breather filters on the reservoir are properly fastened.
7. Do not run the system unless all normally provided filtration devices are in place.
8. Make sure that the fluid used or added to the system is of a type recommended by the manufacturers of the system components.
