Parts for your 1986 Mitsubishi Pajero-Cluth slave cylinder

1986 Mitsubishi Pajero clutch slave cylinder: purpose, upkeep, and when to replace

Based on technical sources — including the Mitsubishi Pajero/Montero Factory Service Manual (Group 21 – Clutch, 1983–1991), the Mitsubishi ASA/CAPS parts catalogue, and aftermarket catalogues from Exedy, Aisin, and Repco — the 1986 Mitsubishi Pajero with a manual gearbox uses a hydraulic clutch system with a clutch master and a clutch slave cylinder. So yes, a cluth-slave-cylinder is relevant and fitted to this model.

On a 1986 Pajero, the clutch slave cylinder sits on the gearbox bellhousing and converts hydraulic pressure from the master cylinder into the push that moves the clutch fork. That movement disengages the clutch so gears slot in cleanly. When the slave gets tired — usually from seal wear, heat, grit, or just age — drivers notice a soft or sinking pedal, difficulty selecting gears at a standstill, or fluid weeping around the bellhousing and boot.

For owners looking after a cluth-slave-cylinder on an older Pajero, a bit of routine attention goes a long way. Fresh, clean fluid and a leak-free system help keep pedal feel consistent and the clutch engaging where it should. Given the age and the 4x4 life these trucks often lead, it’s smart to inspect the slave whenever the vehicle is on stands or during a clutch service.

• Service tips:
  • Flush the clutch hydraulic fluid (DOT 3 or DOT 4) every 2 years or around 40,000 km, brake fluid absorbs moisture and can corrode internal bores.
  • Check for dampness at the slave cylinder dust boot and line fittings. Any leak means replacement is on the cards.
  • Inspect the flexible hose to the slave for cracking or ballooning, replace if perished and re-bleed the system.
  • After fitting a new slave, torque the mounting bolts correctly, confirm pushrod free play, and bleed at the slave nipple until bubbles are gone and the pedal feels firm.
  • If off-roading or fording water, clean away mud and grit around the clutch fork boot to protect the seal.

Replacement is straightforward for a competent home mechanic: secure the vehicle, cap or drain the reservoir, swap the unit, then bleed with a clear hose until the fluid runs clean and bubble-free. A quality cylinder from a reputable brand and a fresh boot on the fork will keep the 1986 Pajero’s shift feel tidy for years.

Popular questions about the 1986 Mitsubishi Pajero cluth-slave-cylinder

Does a 1986 Mitsubishi Pajero have a clutch slave cylinder?
Yes. Factory documentation and major parts catalogues specify a hydraulic clutch with a master and a slave cylinder for manual-transmission 1986 Pajero models. The slave is mounted on the bellhousing and works the clutch fork.

What are the signs the slave cylinder is failing on a 1986 Pajero?
Typical signs include a soft or sinking clutch pedal, trouble engaging gears (especially reverse and first), fluid loss from the reservoir, or visible leaks around the slave boot. If the pedal picks up very low or the clutch drags, the slave may be bypassing internally.

What fluid should be used and how often should it be changed?
The clutch hydraulic system uses DOT 3 or DOT 4 brake fluid. For Aussie and Kiwi conditions, a 2-year or roughly 40,000 km flush helps prevent corrosion and keeps pedal feel consistent, especially if the vehicle tows or sees off-road use.
