DRIVE GP-FINAL 9Q5696 - Caterpillar

Personal injury can result from hydraulic oil pressure and hot oil.Hydraulic oil pressure can remain in the hydraulic system after the engine has been stopped. Serious injury can be caused if this pressure is not released before any service is done on the hydraulic system.Make sure all of the work tools have been lowered to the ground, and the oil is cool before removing any components or lines. Remove the oil filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand.
Personal injury or death can result from sudden movement of the lift cylinders or the tilt cylinders. Do not stand under the work tool when you are testing or adjusting the lift cylinders or the tilt cylinders.Do not stand under the lift arms when you are testing or adjusting the lift cylinders or the tilt cylinders.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.

This test will help to determine if the tilt cylinder is causing a drift problem. When the oil port at the rod end of the tilt cylinder is blocked, the tilt cylinder should not move during a drift test. If the tilt cylinder moves, there is probably internal leakage in the tilt cylinder.Required Tools

Start the engine.
Lower the work tool to the ground.
Stop the engine.
Make sure that the hydraulic oil pressure is relieved from the hydraulic system by completing the procedure that is specified in the Service Manual module Testing and Adjusting, "System Pressure - Release" for the machine that is being serviced. Test Procedure

(D) Connection at rod end of tilt cylinder
Remove hose and install blocking plate (A) at connection (D) for the rod end of the tilt cylinder. Use the four bolts that are specified with blocking plate (A). Note: Make sure that the blocking plate is centered in order to prevent any leakage during the test.
Start the machine. Raise the work tool approximately 1 m (3.3 ft) above the ground.
Check the cylinder rod
