Yuesstloo Engine Timing Alignment Locking Tool Kit — 4PC Camshaft Adjusters & Injector Puller, Steel Mercedes‑Benz Fit

Yuesstloo Engine Alignment Locking Timing Tool Kit is a complete steel set for aligning camshafts, marking pulse wheels, and removing/installing fuel injectors on compatible Mercedes-Benz engines.

This compact kit combines four camshaft timing tools, camshaft adjusters, sleeves, fixing screws, a fuel injector puller and gloves in a molded carrying case so technicians can set timing angles and service injectors with precision. Built from corrosion-resistant steel and designed to match specific OEM fitments, the set helps you locate correct camshaft positions and safely extract or seat injectors without guessing or makeshift tools. The kit targets several Mercedes-Benz families where accurate timing alignment and injector handling matter during repairs, rebuilds or routine maintenance.

Which engine models does this tool kit work with?

The kit is engineered for a range of Mercedes-Benz gasoline engines. It includes specialized items that fit several model families so you avoid mixing incompatible parts during timing service.

• Camshaft alignment tools: compatible with Mercedes-Benz M157, M276 and M278 engine families.
• Camshaft adjuster tools: match M152, M276.8, M276.9, M278 and M157 variants for pulse wheel marking.
• Fuel injector puller and seal installer: fit M133, M152, M157, M260, M264, M270, M274, M276 and M278 engines.
• OEM cross-references included for easier verification against factory numbers.

How does each component help during a timing or injector service?

Each piece in the kit performs a focused role so you can complete timing alignment and injector removal with fewer steps. The tools lock and index camshafts, mark pulse wheels for reassembly, and remove or install injectors without damaging the nozzle or seat.

• Camshaft timing pins: lock camshafts to the correct timing angle during belt/chain or head removal.
• T100 and T60 cam sleeves: support correct cam orientation and protect surfaces while aligning.
• Camshaft adjuster tools: provide a guide to mark pulse wheels for precise reinstallation.
• Fuel injector puller and seal tool: remove injectors and install seals cleanly to avoid leaks.

What materials and build quality can I expect?

The set is manufactured from heat-treated, high-strength steel for jobs that demand repeatable accuracy. Corrosion and wear resistance reduce the risk of tool failure and help maintain tolerances cycle after cycle.

• High-strength steel construction for durability under workshop use.
• Corrosion-resistant finishes to withstand oil, coolant and workshop environments.
• Precision-machined mating surfaces to match OEM fitments and reduce slop.
• Molded carrying case keeps components organized and protected between jobs.

How do I use this kit safely and efficiently?

Follow vehicle manufacturer procedures for locking camshafts and relieving fuel system pressure before using any removal or alignment tool. Work methodically: lock the crankshaft and camshafts, mark pulse wheels if required, use sleeves and fixing screws to stabilize, then remove or install injectors with the puller and seal tool.

• Always depressurize the fuel system before removing injectors to avoid spray hazards.
• Use the camshaft sleeves and fixing screws to prevent movement while adjusting timing components.
• Reference engine-specific service manual torque and sequencing for reassembly.
• Wear supplied gloves and eye protection to reduce contamination and injury risk.

This kit is tailored to professionals and experienced DIYers who repair or maintain Mercedes-Benz engines that require precise timing alignment and injector handling. It is not a universal tool set for all cars, so verify engine compatibility before purchase. If you work on M133–M278 series engines, the Yuesstloo kit offers a consolidated solution to index camshafts, mark pulse wheels and remove/install injectors without improvisation, saving time and reducing the chance of assembly errors.
