CHASSIS AND DRIVELINE INSPECTION

– Check for contamination—clean and flush necessary – Inspect for deterioration – Inspect for faulty connectors kinks

After Overhaul. A complete cleanup the transmission system after overhaul cannot assumed. Repeated cleaning and flushing may not remove all debris from the transmission fluid cooler system. Refer GN4008EN, InChassis Maintenance, for cooler flushing procedure.

NOTE: When equipment flush the oil cooler is not available, install a filter in the cooler line between the oil cooler and the transmission “from cooler” port. The cooler circuit pressure drop specifications must still met. For 1000 Product Family transmissions, pressure drop must not exceed 241 kPa @ 22.7 liters/min flow (35 psi @ 6.0 gal/min). For 2000 Product Family transmissions, pressure drop must not exceed 159 kPa @ 30.3 liters/min flow (23 psi @ 8.0 gal/min). Frequent initial changes this filter element may required debris is flushed out the oil cooler circuit. Closely monitoring change in cooler circuit pressure drop will indicate when a filter change is needed.

5–5. CHECKING CONTROLS

Inspection. Inspect the following and correct any faulty conditions: • Shift selector: – improper operation – poor electrical connections – improper harness routing • Cab and chassis wiring harness: – poor electrical connections – frayed insulation – wiring damage • Throttle sensor components, if present: – freedom movement – improper routing – bellows damage – improper loose cable mounting
