Function: Seals the CVT assembly while supporting critical components (secondary pulley shaft, differential bearings).
Key Features:
Material: High-strength aluminum alloy (ADC12) with precision CNC-machined bearing bores
Integrated Components:
• Differential bearing races (must match OEM hardness)
• Fluid return galleries (prevents oil starvation)
• Speed sensor mounting points
Failure Modes:
Bearing Bore Wear: Causes shaft misalignment → belt/chain damage (P2817 code)
Cracking: Stress fractures near mounting bolts (over-torque during service)
Sealing Surface Warpage: Leads to fluid leaks (>0.1mm warpage unacceptable)
Critical Service Notes:
Use factory torque sequence (star pattern) for installation
Replace rear cover gasket and all shaft seals during service
Verify bearing pre-load (0.15-0.25mm shim adjustment typically required)
Pro Tip: Apply anaerobic sealant only to specified areas - excess can block oil passages
