Modern hydraulic components require very close tolerances to operate effi ciently at high pressures. Contami nants, no matter how small, cause wear and decrease the life of the piece of equipment. Make sure all components are clean when they're installed and that regular mainte nance practices keep the oil clean. ! !! +E FIII This configuration requires installa tion of a sleeve in the pump's inlet. (P/N) 391-3283-052) options two line installation Generally used for long haul, intermittent operation. When the warning C101 pump/valves should be equipped with a lockable control lever to prevent the unit from accidentally being shifted from the neutral position during travel. Failure to install such a lock may allow the dump bed to raise unin tentionally which can lead to injury and/or damage to the vehicle. © 1992 Commercial Intertech Corp. lubrication and oil recommendations cold weather operations: Oils for use in cold weather should have a viscosity not exceeding 7500 SSU at the minimum start-up temperature. A pour point of at least 20°F below start-up temperature is recommended. Start-up procedures should allow for a gradual warm-up until the oil reaches a reasonably fluid state. All parts are lubricated by the general recommendations: hydraulic oil in the circuit.

If unit has a mounting bracket attached, take it off by removing the four hex nuts and washers. If the spool drags in the bore, inspect the spool for nicks or burrs. If possible, remove these with 330 or finer emery or crocus cloth. Wear on component parts will often indicate what problems existed while the unit was in operation. Listed below are major components and general rules to help you determine acceptable wear limits. 3. Grip the valve end of the pump in a large vise so the drive shafts are exposed. Remove the snap ring from each drive shaft bore in the shaft end cover. If the spool continues to drag, it may be bent or the spool bore may be damaged. Spools are hone-fitted to their individual housings. There fore, damage to either of these components means the entire valve must be replaced. gear housing Wear in excess of .005" cut-out necessitates replacement of the gear housing. 4. Turn the unit end-for-end and grip the shaft end cover in the vise. Place a straight-edge across bore. If you can slip a .005" feeler gage under the straight edge in the cut out area, replace the gear housing. Pressure pushes the gears against the housing on the low pressure side. As the hubs and bearings wear, the cut-out becomes more pronounced. Excessive cut-out in a short period of time indicates excessive pressure or oil contami nation.

Any scoring on gear hubs detect able by touch, or wear in excess of .002" necessitates replacement. Scoring, grooving or burring of outside diameter of teeth requires replacement. Nicking, grooving or fretting of tooth surfaces also necessitates replacement. The gears in the C101 are a matched set. Therefore, both gears must be replaced with another matched set. sides. The off-center hole must be on the high pressure side (valve side) of housing. itself except the light polishing as indicated in disassembly step 6. combination relief valve/check valve Major wear points are the check poppet and internal poppet and seat. The relief valve can be disassembled and cleaned in solvent and blown dry. If parts are worn or the operation of the relief valve is suspect, replace the cartridge. bearings If the gears are replaced, replace the bearings. Worn bearings are indicated by rollers falling out of the cage, pitting or metal flaking from the roller tips or the inside race. Note: The rotation arrows cast in shaft end cover face must point toward the valve. 5. With the pocket seals facing down, place the thrust plate over the bearings in the shaft end cover. Tap thrust plate with a soft hammer to about 1/32" from the machined surface. Bearings should fit into the bore with a light press fit, however, a neat hand fit is allowable. If bear ings do not fit snugly, the bearing bores may be worn and the casting should be replaced. thrust plates The thrust plates seal the oil at the sides of the gears. Wear here will allow internal slippage, that is, oil will bypass within the pump and decrease efficiency..002" maxi mum wear is allowable. assembly Always Use Genuine Commercial Intertech Replacement Parts 1. Wash all parts in solvent and blow dry. 2. Clean shaft seal bores with fine emery cloth to remove any burrs or old sealant. Cut four pocket seals approximately 1/4" long from the pocket seal strip. Insert one pocket seal into each of the slots in the thrust plate. Push each pocket seal all the way in so that it touches the roller bearings. Tap the thrust plate down firmly against the machined surface with a soft hammer. Use a sharp razor blade to trim exposed end of the pocket seal square and flush with the thrust plate. Repeat the proce dure for the valve housing thrust plate. Replace thrust plates if they are scored, eroded or pitted. Apply PermatexTM aviation form-a gasket, #3 non-hardening sealant or equivalent to the O.D. of the seals. Press the seals into the bores with an arbor press. Check center of thrust plates where the gears mesh. Erosion here indicates oil contamination. Wipe off any excess sealant on the O.D. of seal. Pitted thrust plates indicate cavita tion or oil aeration. 6. Insert the end of the drive shaft into the steel sleeve (see Tool List). Lightly grease the drive shaft and sleeve. Insert the integral gear and drive shaft with sleeve into the shaft end cover with a twisting motion. Be careful not to damage the lip seal. Push down carefully until the gear rests against the thrust plate. Remove the steel sleeve. Insert the 3. If bearings were removed at disassembly, drop the high pres sure ring seals in each bearing bore with flat side down. Discolored thrust plates indicate overheating, probably insufficient oil or traveling with PTO engaged, a dangerous practice. Press bearings into their respective bores in shaft end cover and valve housing using a flat bar and arbor press. The bearings will bottom out in the casting and should protrude equally from the machined surface. seals and gaskets Replace all rubber and polymer seals whenever repairing pump. Include all "O" rings, pocket seals behind thrust plates, shaft seals and gasket seals. 7. Lightly coat the gasket seals with grease and install them in the gasket seal grooves in the gear housing. Slip the gear housing over the gears. 4. Place the shaft end cover in a vise with the bearings facing up. Cut two center pocket seals 7/32" long from the pocket seal strip with a razor blade and insert in the thrust plate. Use light grease to hold seals in place. Note: The protrusion on one side of the gear housing must be installed on the low pressure side. valve repairs Repairs to the valve assembly are limited to replacing worn spool seals and relief valve maintenance detailed on page 7. No repair should be attempted on the spool 8. Seat the valve housing assembly on the gear housing. Be sure not to pinch the gasket seals. A light tapping with a soft mallet may be required. Note: The trust plate is designed with distinct high and low pressure Valve spool extends over the high pressure side, and opposite the protrusion on the gear housing. | C101 relief valve maintenance seat area then can be cleaned by flushing with solvent and blowing with air. The load-holding check seats on a machined face in the valve housing. CHECK FLOATING 6 7 PLUNGER CARTRIDGE The relief valve cartridge must be removed to inspect or clean the check's seat area. POPPET SEAT 9. Install the four washers on the cap screws and thread into the shaft end cover. Tighten the cap screws cross-corners to 2400 in./lb. Check for free shaft movement by turning shafts with a wrench. CAP 101 -If cleaning or replacing seals fails to correct relief valve problems, the cartridge should be replaced. 3 SPAING 2 1 Figure 2 Relief Valve 10. Install the spool "O" ring into the groove in the valve at the end opposite from the detent housing. Apply a light coating of clean hydraulic oil to the spool. Insert the spool into the housing from the detent cap end. Be careful not to cut the "O" ring. Push the spool through the housing. item qty description 1 ..... 1 O-ring ................ 391-2881-247 2 ..... 1 O-ring ................ .391-2881-497 3..... 1 O-ring .................391-2881-249 4 ..... 1 Back-up Ring ......391-2681-324 ..... 1 O-ring ...............391-2881-461 ..... 1 O-ring ............. 391-2881-727 7 .... 1 Back-up Ring ......391-2681-416 8 ..... 1 Screen ............ 391-2781-011 C101 units produced after February 1, 1983 have a tubular wire screen which fits snuggly over the poppet end of the relief valve. The screen greatly reduces the possibility of contamination reaching the seat area. It is available as a service part (Part No. 391-2781-011) and can be retrofit on all C101 relief valves, (Part No. 355-9001-067). 11. Apply a light coating of oil to the second spool "O" ring and install it over the spool and into its groove behind the detent retainer. C101 relief valve adjustment 12. Attach the detent retainer with the four cap screws. It must be carefully aligned so it does not contact the spool. 13. Install the detent ball, spring, washer and retainer. Commercial's C101 pump/valve units have unique internal passages in the valve assembly that allow the relief valve to function as a main and a port relief and a load-hold check. All mechanical structures integrated with the hydraulic system are consequently protected from overload and excessive shock stresses. All relief valves in these units are factory pre-set at 2000 psi. The table below has been developed to aid in the readjustment of these relief valves if it becomes neces sary. 14. Install the retainer ring and snap ring on the front end of the spool. 15. Install the relief valve in the housing. Back off the adjustment screw to the lowest possible pressure setting. To readjust the relief valve, loosen the jam nut and turn the adjustment screw counter-clockwise the prescribed number of turns. 16. Slip spool end cap over the rear spool clevis. Align the pin eye in the spool with the slot in the spool end cap and install the spirol pin. Next install the bracket with two (2) socket head cap screws. Figure 2 shows the arrangement of internal parts and the location of the serviceable seals. If contamination lodges between the poppet and seat, the relief valve will leak internally and prevent the cylinder from being pressurized or allow the load to drift.

Finish assembling the C101 by installing the 3-line sleeve and mounting bracket option that fits your individual requirements. The relief valve can be cleaned without altering its pressure setting by removing the 1-3/8" hex car tridge cap. The floating seat, spring and plunger can then be removed as a subassembly.
