Daihatsu Hijet — Clutch
Cable free play adjustment, disk inspection limits, and replacement procedure.
Cable Specifications
Cable Free Play at Pedal
15 – 25 mm

139 – 149 mm
Pressure Plate Bolt Torque
185 ± 35 kg·cm
Release Bearing Service Interval
Every 80,000 km
Tip:Check cable free play before diagnosing slipping or hard engagement. A cable with no free play causes the clutch to partially disengage at rest, accelerating disk wear. Too much free play causes incomplete disengagement and grinding gear changes.
Cable Adjustment
- Locate the clutch cable adjuster where the cable enters the transmission bellhousing — there is an adjustment nut and a lock nut.
- Loosen the lock nut. Turn the adjustment nut to increase or decrease pedal free play.
- Measure free play at the clutch pedal pad. Target: 15 – 25 mm of travel before resistance is felt.
- Tighten the lock nut once free play is set. Re-check the measurement after locking — the lock nut can pull it slightly.
- Verify pedal deck height (floor to pedal pad at rest): 139 – 149 mm. If out of range, adjust the pedal stop bolt at the bracket.
Cable Replacement
- Remove the clutch housing dust cover from the bellhousing.
- Back off the adjustment nut fully to create slack in the cable.
- Disconnect the cable end from the release fork inside the bellhousing.
- Remove the two cable bracket retainer bolts. Lift up on the clutch pedal and pull the cable free from the pedal assembly.
- Some models have a lock clip at the pedal end — release this before pulling the cable through.
- Route the new cable in reverse. Clip the lock clip first, then attach to the fork.
- Set cable free play to 15 – 25 mm and reinstall the dust cover.
Disk Inspection Limits
Rivet Depth Minimum
0.3 mm above rivet head
Disk Runout Limit
1.6 mm
Flywheel Runout Limit
0.10 mm
Disk & Pressure Plate Replacement
Warning:Always replace the release bearing when doing a clutch disk — the bearing is inexpensive and the labor to reach it again is not. Never clean a release bearing with solvent.
- Remove the transmission.
- Attach a flywheel holder tool to prevent rotation. Remove the six pressure plate bolts in a cross pattern and remove the pressure plate and disk.
- Check flywheel runout with a dial gauge — limit is 0.10 mm. Inspect ring gear teeth for damage.
- Apply 0.2 g of high-temp chassis grease to the input shaft spline. Keep grease off the friction material.
- Use a clutch alignment tool to center the new disk in the flywheel, then set the pressure plate over it.
- Install the six bolts and torque in a cross pattern to 185 ± 35 kg·cm. Remove the alignment tool.
- Replace the release bearing. Lightly grease the release fork pivot point and the bearing contact surface.
- Reinstall the transmission and set cable free play.
