Installation Notes
Installation steps (overview):
-
Locate clutch master cylinder – on firewall, above or beside brake master cylinder.
-
Drain old fluid – remove fluid from reservoir with a syringe or turkey baster.
-
Disconnect hydraulic line – use flare nut wrench to avoid rounding the nut. Cap line to prevent debris.
-
Disconnect pushrod from clutch pedal – remove clevis pin and cotter pin inside the cab.
-
Unbolt master cylinder from firewall – remove 2 nuts (usually 10mm or 12mm) from engine side.
-
Remove old cylinder – pull out from engine bay.
-
Compare new cylinder with old – check mounting flange, bore size, pushrod length, and port thread.
-
Adjust pushrod length – if necessary, set to match old cylinder‘s clevis position (measure from mounting flange to center of clevis pin hole).
-
Install new cylinder – position on firewall, tighten mounting nuts to specification (typically 10-15 Nm).
-
Reconnect pushrod to clutch pedal – install clevis pin and new cotter pin.
-
Reconnect hydraulic line – tighten fitting gently. Do not cross-thread.
-
Fill reservoir with fresh DOT 3/DOT 4 fluid – do not overfill.
-
Bleed the clutch system – open bleeder on slave cylinder. Have an assistant depress pedal, close bleeder, release pedal. Repeat until no air bubbles. Keep reservoir topped up.
-
Check pedal feel – should be firm with some free play (typically 5-15mm at pedal pad). Adjust pushrod if needed.
-
Test drive – verify smooth clutch engagement and disengagement, no leaks.
