Leach 2R-III - Troubleshooting Tables

Troubleshooting 73
 Excessive system flow rate (cycle time too fast) can agitate the hydraulic fluid. Set the cycle time
according to specifications.
 Do not thin hydraulic fluid with diesel fuel (lowers the flash point). Weather permitting, use a
higher flash point fluid.
After making any repairs on the hydraulic system, bleed the system at reduced engine speed and
pressure to remove any trapped air. Depending on the size of the component, e. g. cylinder, hose, it
may be necessary to cycle the unit several times. Of course the larger the air pocket, the more cycles
are needed. To avoid potential problems, thoroughly bleed all hydraulic systems and ensure that all
inlet connections are tight and not ingesting air.
Troubleshooting Tables
Use the following troubleshooting tables to find remedies to problems that have identifiable signs.
OPERATING IS ERRACTIC
Possible cause Remedy
Speed up system operating erratically Check electrical system. See Chapter 8 Service and
Repair.
Hydraulic fluid too hot Check for proper grade of fluid (see Leach Hydraulic
Fluid Recommendation on page 42).
Hydraulic fluid level too low Check fluid level. Add fluid if necessary.
Bypass in cylinders Test for leaking cylinders. See Chapter 8 Service and
Repair.
Hydraulic fluid too cold Bring fluid to operating temperature. Check for
proper grade of hydraulic fluid (see Leach Hydraulic
Fluid Recommendation on page 42).
Operating linkage bent or binding Repair, replace or realign damage linkage.
