1. 1

   Perform a spool leakage check by testing the valve to see if pressure can be obtained on each port one at a time. If no pressure is built, oil is likely leaking around the spool, meaning the valve assembly will need to be replaced.

2. 2

   Visually inspect for minor leaks around the valve block. Minor leaks can often be fixed by simply tightening fittings or replacing external seals.

3. 3

   Check hydraulic fluid (UTTO) level and condition. Ensure fluid is not contaminated and filters are not clogged (filters should generally be changed every 300–500 hours).

1. 1

   Remove cap bolts

   Remove the bolts securing the cap on the hydraulic lift cover.

2. 2

   Remove cap

   Remove the cap and carefully detach it from the standpipe. Caution: Ensure that the standpipe is not dislodged from its seat in the hydraulic pump.

3. 3

   Remove valve bolts

   Remove the bolts securing the faulty hydraulic valve to the base plate.

4. 4

   Separate valve

   Separate the valve and the base section.

5. 5

   Fit standpipe

   Fit the standpipe into the inlet port of the new/repaired base plate.

6. 6

   Fit base plate

   Fit the base plate to the lift cover, ensuring the standpipe is correctly located into its seat on the hydraulic pump.

7. 7

   Secure base plate

   Secure the base plate to the lift cover.

8. 8

   Secure new valve

   Secure the new control valve to the base plate using the bolts removed earlier.

9. 9

   Top off fluid and replace filter

   Top off the system with fresh UTTO hydraulic fluid and replace the hydraulic filter to prevent contamination of the new valve.
