Premium Timing Belt Tensioner for Ford and Mercury

DJ Rock TBT420 is a premium engine timing belt tensioner bearing built to maintain correct timing belt tension and stable camshaft-crankshaft synchronization. It is a direct-fit service part for select Ford Focus, Ford Escort, and Mercury Tracer applications, including 2000-2004 Ford Focus and 1997-2002 Ford Escort timing belt service.

Key Features

  • Premium grade timing belt tensioner bearing for engine valve train service
  • Helps maintain accurate belt tension to reduce slippage and misalignment
  • Built with high-carbon chromium steel bearing elements and races for strength and fatigue resistance
  • Uses durable sealing materials to help keep contaminants out and retain lubrication
  • High-temperature grease supports consistent operation in demanding engine conditions
  • Compatible with select Ford Focus, Ford Escort, and Mercury Tracer timing belt applications
  • Part number TBT420 for easy catalog lookup

Detailed Description

DJ Rock TBT420 timing belt tensioner bearing is engineered for engines that rely on precise valve timing. By keeping the timing belt properly tensioned, it helps preserve synchronization between the crankshaft and camshaft, which is critical during routine timing belt service on the Ford Focus, Ford Escort, and Mercury Tracer. The bearing design uses durable materials selected for high-speed engine operation and long-term wear resistance.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Timing belt slack that can affect engine synchronization
  • Belt noise caused by worn tensioner bearings
  • Misalignment during timing belt replacement service
  • Premature wear from contaminated or dry bearing surfaces
  • Valve timing issues related to a failing tensioner assembly

Installation Notes and Tips

Replace the tensioner bearing during timing belt service whenever wear, rough rotation, or noise is present. Inspect the timing belt, idler bearings, and related components before reassembly, and verify correct belt routing and tension after installation. Confirm vehicle application by year, make, and model before ordering TBT420.

Quality Assurance

DJ Rock lists this as a premium-grade component manufactured to meet or exceed OEM quality standards for modern engine environments.
