SUMO Land Rover Crankshaft Repair Sleeve

Extended Seal Surface Upgrade | Front Crankshaft

Part #: S-LR-CRS

Product Overview

The SUMO S-LR-CRS Crankshaft Repair Sleeve is an engineered upgrade designed to restore worn or damaged front crankshaft seal surfaces on Land Rover engines. Unlike narrow, generic repair sleeves, the SUMO design features increased sealing surface area, tighter tolerances, and improved installation control to prevent seal damage and repeat oil leaks.

This sleeve is purpose-built to eliminate common failure modes seen with traditional sleeve–style repairs, where limited width allows seals to walk, catch an edge, or tear during installation.

Key Advantages

• Extended-width sealing surface
  Provides greater contact area than narrow repair sleeves, reducing seal walk and edge loading.

• Improved tolerance control
  Precision fitment ensures concentric alignment for proper seal function.

• Reduced installation risk
  Minimizes seal edge damage during installation and initial engine rotation.

• Prevents repeat oil leaks
  Designed to solve the root cause of seal failure, not just mask surface wear.

• Professional-grade solution
  Ideal for engine rebuilders, restoration shops, and professional technicians.

Common Problems with Narrow Sleeves (What This Fixes)

• Seal slipping off the sleeve

• Seal catching the sleeve edge and tearing

• Immediate or short-term oil leaks after installation

• Lost labor time and customer dissatisfaction

• Repeat tear-downs for “successful” repairs

The SUMO S-LR-CRS eliminates these issues by providing a wider, more forgiving sealing surface that supports proper seal engagement throughout operation.
