Component check

1 Check the seat with compressor and heater (A29)

Action:

Perform a visual inspection of the seat with compressor and heater (A29) and of the connectors associated with it:

Check for signs of damage or dirt. Check the electrical connections for bad, loose, widened, slid-back or corroded contacts; also check the leads.

Result:

OK: Test completed.

NOT OK: Carry out an operational test.

PowrQuad Transmission - System Check

CAUTION:

Observe the safety precautions! See Hydraulic System - Safety Measures for Hydraulic Checks in Section 270.

The following tests represent a step-by-step approach to troubleshooting. Proceeding from the operational checks , the purpose of these tables is to help locate faults in the transmission circuit and power train.

These tests must be carried out when power train elements fail to operate or operate too slowly, when the hydraulic oil overheats and whenever major repairs have been carried out on the power train elements.

Faults in the transmission circuit involve: transmission pump, power train elements, valves, oil cooler and transmission lubrication.

System check

1 Preconditions for proper system checking procedure

Action:

To ensure that the system is checked properly, do the following checks first.

See General Information - Transmission and Hydraulic System, Introductory Checks , Section 210.

See PowrQuad Transmission - Operational Check-Out in Section 255.

Result:

OK: GO TO 2.

NOT OK: If possible, rectify any faults that become apparent prior to doing the system check.

2 Check transmission oil temperature

Action:

Result:

OK: GO TO 3.

NOT OK: See Hydraulic System - Heat Up the Hydraulic Oil in Section 270.

3 Check system pressure

Item Measurement Specification

Transmission oil temperature during pressure checks

Temperature min. 45C min. 113F

Action:

See PowrQuad Transmission - Check System Pressure in Section 255.

Adjust the system pressure if not within specification.

If system pressure cannot be adjusted properly, check the components that are dependent on system pressure.

Also, before checking or reconditioning the transmission oil pump, check the primary filter screen in the differential housing for restriction, and check the flow rate of the transmission oil pump.

Result:

OK: GO TO 4.

NOT OK: See PowrQuad Transmission - Adjust the System Pressure in Section 255.

4 Check the components that are dependent on system pressure (such as front-wheel drive, differential lock and rear PTO)

Action:

See Drive Systems - Checks and Adjustments, Summary of References in Section 256.
