Yuesstloo Engine Alignment Locking Timing Tool Kit for Mercedes M‑Series, 4PC Camshaft Adjusters, Hardened Steel

This kit combines precision camshaft timing tools, camshaft adjusters, and an injector puller in a compact carrying case so technicians and experienced DIYers can maintain correct timing geometry and remove injectors without damage. Built from hardened steel with corrosion-resistant finishes, the set aims to simplify time-consuming alignment and removal tasks on specific Mercedes M-series engines. Included gloves and organized storage make it convenient to transport and protect components between jobs.

Which engines and jobs is this kit designed for?

The tools are purpose-made for many Mercedes-Benz M-series engines and for tasks that require accurate camshaft locking and injector removal. Compatibility covers models such as M157, M276, M278 and related families, plus injector work on additional M-series variants.

• Covers Mercedes-Benz M157, M276, M278 camshaft timing procedures.
• Injector puller fits M133, M152, M157, M260, M264, M270, M274, M276 and M278 engines.
• Includes camshaft adjuster tools suited to M152, M276.8, M276.9, M278/M157 applications.
• Works for timing alignment, pulse wheel marking, and injector removal/install tasks.

How do these tools improve timing and injector work on the bench or in the bay?

The set provides dedicated locating and locking pieces that maintain exact camshaft positions during service, reducing rework and timing error risk. The injector puller removes injectors cleanly while the sleeves and adjuster pieces allow pulse wheel marking and precise alignment.

• Camshaft timing tools hold the camshafts at the correct angle for safe disassembly.
• Adjuster tools enable controlled marking and alignment of the pulse wheel on removed camshafts.
• Fuel injector puller minimizes damage to injector bodies and seats during extraction.
• Sleeves and fixing screws provide consistent fitment and repeatable positioning.

What exactly is included and what are the material benefits?

The kit contains multiple camshaft-specific pieces and accessories to tackle timing and injector removal jobs without sourcing separate tools. Components are manufactured from high-strength steel for long life and resistance to wear and corrosion.

• 4 camshaft timing tools compatible with OEM reference 276 589 01 40 00.
• 4 camshaft adjuster pieces (OEM ref 278 589 00 23 00) plus T100 and T60 cam sleeves.
• Fuel injector puller, 8 fixing screws, installation gloves, and a molded carrying case.
• Heat-treated steel construction for durability and rust resistance.

What should I expect when using this kit in practice?

Expect faster setup times and a neater workflow compared with improvised methods. Proper locking and alignment reduce the chance of timing-related reassembly errors and make injector removal safer and more predictable.

• Organized case keeps all tools accessible and protected between jobs.
• Gloves reduce grease transfer and improve grip during handling.
• Durable parts tolerate repeated use in professional garages and home shops.
• Clear fitment to specific Mercedes engines simplifies tool selection for a task.

Who this kit is for: The Yuesstloo Engine Alignment Locking Timing Tool Kit is aimed at professional mechanics, independent repair shops, and experienced DIY enthusiasts who work on Mercedes-Benz M-series engines and need reliable camshaft locking, adjuster tools, and a safe injector removal solution. It’s not intended as a universal timing set — check engine compatibility before purchase to ensure the specific M-series variant is supported.
