S&S TC3 Oil Pump & Cam Plate Kit for Twin Cam

Harley Twin Cam Performance Oil System Upgrade

Fix One of the Biggest Weak Points in a Twin Cam

If you own a Twin Cam Harley…You already know the stock oiling system has limits.

Weak scavenging. Oil pump failures. Tensioner wear. Valve train instability at higher RPM.

👉 Ignore it long enough, and it gets expensive.

S&S TC3 Oil Pump & Cam Plate Kit

This is one of the best upgrades you can make to improve the reliability and performance of your Twin Cam engine.

Designed to increase oil control, improve scavenging efficiency, stabilize the valve train, and handle aggressive riding conditions far better than the factory setup.

What This Upgrade Actually Does

• Improves oil pressure stability
• Increases scavenging efficiency
• Helps protect against oil pump failure
• Supports higher RPM and performance cam setups
• Improves valve train control

Built for Performance & Reliability

• Precision CNC machined forged aluminum construction
• Increased structural strength + dimensional stability
• Designed to eliminate common stock system weaknesses

Why Riders Upgrade to the TC3 System

The stock Twin Cam oiling system struggles under:

• Aggressive riding
• Higher lift cams
• Performance valve springs
• Sustained RPM

👉 The TC3 system was built to solve that.

Advanced Scavenging Design

Unlike the stock setup, the TC3 features:

• Separate scavenge sections for:
  • Flywheel cavity
  • Cam chest

This scavenges each area more efficiently with less interference for improved oil control.

Built to Survive Real Conditions

• Gerotors tolerate more pinion shaft runout without damage
• Magnetic trap protects scavenge rotors from debris
• Adjustable oil pressure regulator can be tuned externally

Huge Upgrade for 1999–2006 Models

The 99–06 cam plate version is specifically designed to use:
👉 Late-style hydraulic cam chain tensioners

Why that matters:

• Stock spring-loaded tensioners struggle at higher RPM
• Especially problematic with:
  • Bigger cams
  • Stronger valve springs

The TC3 system fixes that weakness.

Serviceability Matters Too

• Removable passage plugs for service
• Replaceable bronze bushings on applicable models

Built to last—and built to be maintained properly.

Designed and manufactured in the USA by S&S Cycle.
