Troubleshooting
Detecting Internal Leak in Cylinders
An internal leak is caused by a damaged seal inside the hydraulic cylinder (see #1 in Figure 12
1).
Because the cylinder is leaking oil inside (bypassing), a certain amount of pressure is lost, reducing
the efficiency of the cylinder and its capacity to push and/or pull.
No control on all
cylinders
Hydraulic system off
Engage the hydraulic system
Slipping clutch
Oil supply
All or any of the following:
- Replace filter (see page 81)
- Clean supply line
- Change hydraulic oil
- Hydraulic oil is too cold
No flow or pressure
See “Pump-Related Problems” Table
above
Contaminated oil
Change filter and oil (see
on page 78 and
Wrong type of oil
Change filter and oil (see
on page 78 and
Faulty control valve
Repair, adjust or replace
