Rear Cover K114 CVT Transmission Housing 5 Fixing Holes Toyota C-HR 2.0L 2019

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:

1. Use factory torque sequence (star pattern) for installation

2. Replace rear cover gasket and all shaft seals during service

3. 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
