Yuesstloo Engine Timing Tool Kit for Mercedes M133–M278 — 4pc Camshaft Adjusters, Injector Puller, Hardened Steel Case

Yuesstloo Engine Alignment Locking Timing Tool Kit is a complete set of camshaft timing and adjuster tools designed to accurately lock, align, and service Mercedes M133–M278 family engines.

This compact kit gathers the specialized fixtures technicians need to set camshaft timing, remove fuel injectors, and mark pulse wheels during repair or maintenance. Built from hardened steel and supplied in a carry case, it combines multiple OEM-compatible parts so you can work cleanly and quickly on modern Mercedes-Benz petrol engines that require precise timing reference points.

Which engines and repairs is this kit suitable for?

The kit covers a wide range of Mercedes-Benz engines including M133, M152, M157, M270, M274, M276 and M278 families, and offers adjuster fittings compatible with several M152/M276/M278 variants. It’s intended for camshaft locking, timing angle alignment and pulse wheel marking during disassembly, reassembly or timing belt/chain service.

• Fits Mercedes M133, M152, M157, M270, M274, M276, M278 engines
• Includes adjuster tools compatible with M152, M276.8/9, M278/M157 types
• Useful during cam timing, injector removal and pulse wheel marking

What parts are included and how do they help me work faster?

The kit bundles four camshaft timing tools, four camshaft adjuster pieces, two cam sleeves (T100 and T60), a fuel injector puller, eight fixing screws and gloves—everything organized inside a carrying case. Having OEM-equivalent tools on hand reduces setup time and avoids jury-rigging, so you can lock shafts and reference timing marks reliably on the bench or under the hood.

• 4x camshaft timing tools (OEM: 276 589 01 40 00) for secure locking
• 4x camshaft adjuster tools (OEM: 278 589 00 23 00) for accurate pulse marking
• T100 and T60 cam sleeves and injector puller for safe component removal

How durable and precise are the tools?

Manufactured from high-strength steel, the Yuesstloo tools resist corrosion and wear so they keep accurate fit and alignment over repeated use. The robust construction minimizes deformation during torque and handling, ensuring the timing fixtures retain precise engagement with camshafts and chain or belt components.

• Heat-treated steel for long-term strength and dimensional stability
• Corrosion-resistant finish to protect critical mating surfaces
• Supplied fixing screws and sleeves maintain repeatable positioning

How do I use the injector puller and adjuster tools safely?

The fuel injector puller fits over injector bodies to extract them without damaging seals or housings; the camshaft adjusters help mark the pulse wheel on a removed camshaft for correct reassembly. Follow vehicle-specific service manuals for torque specs and timing procedures; use the provided gloves and the case to keep parts organized and contamination-free.

• Use the puller to remove injectors vertically with steady force
• Install cam sleeves and locking tools to fix shaft positions before work
• Mark pulse wheel with the adjuster tool before camshaft reinstallation

Who is this for? This Yuesstloo kit is aimed at professional mechanics, independent Mercedes specialists and experienced DIYers who maintain or overhaul modern Mercedes petrol engines that demand precise camshaft timing. If you service M133–M278 family engines regularly or want an OEM-compatible timing toolkit for occasional major jobs, this set supplies the right fixtures, fasteners and organizer to get the job done with repeatable accuracy.
