Install bolts, washers and nuts and torque to 75-100 ft.-lbs. F-2486-10-86 13 Regular maintenance of the loader hydraulic system will insure maximum loader efficiency and long life. A WARNING: NEVER perform maintenance beneath a raised loader. DAILY MAINTENANCE • Check level of hydraulic oil in loader left side frame reservoir before starting each day’s operation. If necessary, add oil to bring the oil level up to the level plug at the rear of side frame. Use a good quality AW# 15 hydraulic oil. Type A or F transmission fluid is acceptable. If the hydraulic system becomes contaminated with moisture or other foreign material, drain the system, flush with clean hydraulic oil and refill with new hydraulic oil. After the first fifty hours of operation, change the oil filter element (10-15 micron rating) and thereafter, after every two hundred and fifty hours of operadon. After the first twenty-five hours of operation, clean the screen in Y-strainer and thereafter, after every two hundred and fifty hours of operation. Clean screen by removing threaded cap and screen from Y-strainer body, then use a suitable cleaning solvent to remove any foreign particles from screen and put it back into Y-strainer body. • After every eight hours of operation, lubricate the eight grease fittings: one at each lift boom arm to side frame and bucket pivot, and one at rod end of each bucket and lift cylinder. • After every ten hours of operation, check all hardware and tighten where required. • Replace hoses immediately if they are damaged by a cut or scrape, extruded at the fittings or leaking. Hydraulic oil leaks should be repaired promptly to avoid loss of oil and serious personal injury from escaping oil. A CAUTION: Use a piece of cardboard or wood rather than hands and wear eye protection when searching for hydraulic leaks. Escaping hydraulic oil under pressure can have sufficient force to penetrate the skin. If oil is injected into skin, it must be surgically removed within a few hours by a doctor or.gangrene may result. HYDRAULIC PRESSURE CHECK Follow the following procedure to check if the loader is operating at the correct hydraulic pressure. 1. Obtain a pressure gauge that registers 3000 PSI in 50 PSI increments. 2. Install pressure gauge into the hydraulic line connecting loader valve to the base port of bucket cylinders. 3. Stan tractor engine and adjust throttle so engine is running at 3000-3400 RPM. 4. Push bucket control to pressurize hydraulic line with gauge attached. Hold control until cylinders reach the fully extended position. Holding control with cylinders fully extended will give you the hydraulic system pressure on the gauge. 5. The pressure for your loader hydraulic system should be 1400 PSI maximum when equipped with Dukes Fluid Power model 1627 DM valve. 6. If the pressure is not correct, refer to the “Troubleshoot ing” section for possible remedy, or contact an authorized service department. A Safe Practice ... Is your Best Protection TROUBLESHOOTING- TROUBLESHOOTING PROBLEM POSSIBLE CAUSE REMEDY 1. Loader slow or will not lift and/or dump. Hydraulic oil too heavy. Oil filter plugged. Hydraulic pump worn. Oil line restricted or leaking. Control valve does not shift properly. Air in hydraulic system. Cylinder leaks intemaliy-Faulty valve. Change to proper oil Clean or replace filter. Repair or replace pump. See "Pump Service”. Check all hoses and tubes for leaks, damage or restrictions. Replace damaged or restricted hoses or tube lines. Inspect, clean, repair or replace valve. See "Valve Service”. Cycle lift cylinders and bucket cylinders several times to free system of air- Replace seals. See "Cylinder Service”. Repair or replace valve. See ,rValve Service”. 2. Loader chatters or vibrates when raising or lowering. Air leak in pump inlet line-Air in hydraulic system. Oil level too low. Check, tighten or replace inlet line. Cycle lift cylinders and bucket cylinders. Add oil as reauired. 3. Pump noisy. Inlet line restricted or leaking. Oil level too low. Pump worn or damaged. Check for air leaks, restrictions or collapsed hose. Tighten or replace hose. Clean filter if necessary. Add oil as required. Repair or replace pump. See "Pump Service”. 4. Oil leaks. Defective fittings or hoses. Loose connections. Worn or damaged o-ring or wiper seal in cylinder rod end. Worn or damaged o-rings in valve. Replace defective parts. Tighten fittings. Install a seal repair kit. See "Cylinder Service”. Install an o-ring repair kit. See "Valve Service”. 5. Insufficient lift capacity. Improper hydraulic pump operation. - Load is greater than boom lift capacity. Internal boom cylinder leakage. Improper hydraulic valve operation. Repair or replace pump. See "Pump Service”. Check loader specifications. Replace any worn parts and install a seal repair kit. See ’’Cylinder Service”. Repair or replace valve. See ”Valve Service”. 6- Excessive wear on bucket cutting edge. Bucket is riding on cutting ed...
