-
-
Function: Engages low/reverse gears by actuating multi-plate clutch packs in planetary gearset applications (common in 4WD/RWD transmissions).
Key Components:
-
Drum Body: Hardened aluminum or steel with precision splines for clutch plate engagement
-
Integrated Piston: Hydraulically actuated with reinforced seals for high-pressure apply (60-100 psi)
-
Bleed Channels: Prevent clutch drag during release
Failure Modes:
-
Spline Wear: Causes incomplete clutch engagement (slippage in low gear)
-
Piston Seal Leaks: Results in delayed reverse engagement
-
Drum Cracks: Thermal stress near weld points (sudden loss of drive)
Critical Checks:
-
Measure drum runout (<0.08mm)
-
Verify clutch clearance (1.0-1.8mm typical)
-
Inspect for blueing (overheating evidence)
Pro Tip: Always replace drum seals during rebuilds – reused seals have 80% higher failure rate.
