CYLINDER GP-TILT 2424273 - Caterpillar

End Post Assembly
Raise the end post to its highest position once a month and lubricate the shaft with SAE 30 oil.
1. KEEP ALL TOOLS, LOOSE NUTS AND BOLTS, MUD GUARDS AND ANY OTHER MISCELLANEOUS ITEMS OUT OF THE BED.2. IF THE LOCKING MECHANISM FOR THE CHAIN TIGHTENER ASSEMBLY STARTS TO STIFFEN, THERE IS PROBABLY DIRT OR PAINT CHIPS IN THE THREADED SHAFT. DISASSEMBLE AND CLEAN WITH SOLVENT.
Troubleshooting
The 6V4947 HYDRAULIC CYLINDER REPAIR STAND has been designed for simplicity of operation and maintenance. With its power unit's relief valve pre-set at a safe operating pressure (3000 PSI), the problems that could develop with the unit will probably be mechanical.Items to be checked on the cylinder repair stand on at least a weekly basis are:Cylinder Mounting Assembly: P.N. 70 010 000
Fasteners should be checked and tightened if they have worked loose. Special care should be taken for the fasteners that hold the hydraulic package mounting arm (item 12 on page 24) in place. If the fasteners continue to work loose, use liquid locktite to seal them in place.Torque Multiplier Mounting Assembly: P.N. 70 030 000
Fasteners (especially set screws) should be checked and tightened if they have worked loose. If the lifting mechanism is working improperly, check for a loose or broken chain or possibly a sheared roll pin.End Post Assembly: P.N. 70 060 000
If the end post raises too slowly or not at all, coat the shaft (item 7 on page 32) with SAE 30 oil and check the roll pin (item 16) to see if it has been sheared.Hydraulic Package Mount: P.N. 70 070 000
Fasteners should be checked and tightened if they have worked themselves loose.Chain Tightener Assembly: P.N. 70 080 000
This assembly is very critical to the operation of the V-Block assemblies. The fasteners should be checked each time the equipment is used. Clean all dirt and paint chips away from critical sliding areas and specifically from the shaft (item 4 on page 36) and threaded block (item 3).
Model HCRS Relief Valve Assembly: P.N. 70 112 000Inspect for leaking fittings. Remember, the relief valve (item 9) is pre-set at the factory for 3000 PSI. Any tampering (broken seal) with the valve could result in personal injury.
Fixed V-Block Assembly: P.N. 70 100 000
The problems with the chain locking mechanism are covered under Chain Tightener Assembly (described above). Other than the positioning of the chain in the locking mechanism (see illustration on page 40) and the placement of the height adjustment shims, the only problem with this assembly should be loosened fasteners.Special Problems: Easily Overlooked Handling Mistakes
1. Rod eye will not lock securely in place. a. Incorrect shaft being used.b. Correct shaft incorrectly positioned in end post.c. Button plate incorrectly used. 1) The flat surface of the button plate (no bolts) faces down on the bearing-less rod eyes.2) The buttons (bolts) must be properly located against the flat surface of the rod eye when it is fitted with a spherical bearing.d. Button plate spacer not in place when using the small
