Installation Guide
Required Tools:
- 10mm socket wrench
- Torque wrench (8-10 Nm range)
- New gasket (recommended, not included)
- Degreaser and clean cloth
Installation Steps:
- Ensure engine is completely cool before starting work
- Remove the 4 mounting bolts securing the stock timing cover using a 10mm socket
- Carefully remove the stock plastic cover and inspect the gasket surface
- Clean the engine mounting surface thoroughly with degreaser and allow to dry
- Install new gasket (if replacing) ensuring proper alignment with mounting holes
- Position the Motone MMU045 aluminum cover, aligning all mounting points
- Install mounting bolts and torque to 8-10 Nm in a cross-pattern sequence
- Inspect for proper seating and check for any gaps around the gasket perimeter
Professional Installation: While this is a straightforward upgrade, if you’re not confident working on engine components, we recommend professional installation at an authorized Triumph service center.
Why Upgrade to Aluminum Engine Covers?
The stock plastic timing covers on Triumph Modern Classics serve their functional purpose, but offer limited protection and thermal management. Aluminum engine covers provide three key advantages for daily commuters:
Thermal Performance: Aluminum’s superior thermal conductivity helps dissipate heat from the engine’s timing components, potentially extending component life and improving overall engine bay cooling—particularly beneficial in stop-and-go urban traffic.
Impact Protection: The 6061-T6 aluminum construction is significantly more impact-resistant than plastic. Road debris, gravel, and minor impacts that could crack plastic covers are easily deflected by machined aluminum.
Longevity: Unlike plastic covers that can become brittle, discolored, or cracked over time due to heat cycling and UV exposure, anodized aluminum maintains its appearance and structural integrity for decades.
Maintenance & Care
The brushed aluminum finish requires minimal maintenance to preserve its appearance:
- Regular Cleaning: Wash with mild soap and water during routine motorcycle cleaning. Avoid harsh chemicals or abrasive cleaners that can damage the anodized surface.
- Periodic Inspection: Check mounting bolts for proper torque every 5,000km or 6 months. Vibration can cause gradual loosening over time.
- Gasket Maintenance: Inspect the gasket seal annually. If you notice any oil seepage around the cover edges, replace the gasket using genuine Triumph parts.
- Corrosion Prevention: While the anodized finish provides excellent corrosion resistance, applying a thin coat of aluminum polish 2-3 times per year will maintain the brushed finish’s luster.
