CHECK CLOGGING OF ORIFICE IN PPMU
1. Install an oil pressure gauge (SST: KV40108000) (A) to oil injection jack.
  CAUTION:
  - Clean surrounding areas of oil injection jack using steam before starting operation, since there may be mud on it.
  - Clean oil pressure gauge (special service tool: KV40108000) jack with steam before use.

2. Loosen needle valves A and C of PPMU by approximately 2 rotations for check changes in vehicle height.
  CAUTION: Never loosen the needle valve more than required.
3. Tighten needle valve A and C of PPMU to the specified torque after the inspection.
  Tightening torque : 8.3 N.m (0.85 kg-m, 73 in-lb)
