Yuesstloo Engine Timing Tool Kit — Camshaft & Flywheel Locks, OEM 303-1097/303-1550, Multi-fit

Yuesstloo Engine Timing Tool Kit is a complete camshaft, crankshaft and VTC locking set engineered to hold timing positions accurately while you change belts or service timing systems on a wide range of Ford, Mazda, PSA and Volvo engines.

This professional-grade kit brings together purpose-made alignment pins, holding plates and locking pins that match OEM references (including 303-1097 and 303-1550) so you can lock camshafts, flywheels and tensioners securely during maintenance. The kit covers many Duratec, Duratorq, EcoBoost and Mazda/PSA engine families, saving time hunting for separate tools and reducing the risk of mistimed reassembly.

Which engines and vehicles does this timing kit support?

The set is designed for multiple petrol and diesel engines across Ford, Mazda, PSA and Volvo lineups. It fits twin-cam 16V Duratec engines, Duratorq TDCi/TDDi diesels, EcoBoost Ti-VCT/VVT variants, plus several Mazda/PSA units and selected Volvo 1.6T engines.

• Covers Ford 1.25L–2.5L petrol 16V and 1.4L–2.0L diesel engines.
• Compatible with EcoBoost 1.5/1.6 and Ti-VCT 1.6 engines.
• Fits Mazda 1.4–3.0L and PSA HDi family engines, plus some Volvo 1.6T models.
• Specific vehicle fitment includes Focus, Mondeo, C-Max, Fiesta, Transit Connect, Fusion, S-Max, Galaxy and select Mazda models.

What parts are included and how do they replace OEM tools?

The kit supplies dedicated locking pins, camshaft plates and crank/flywheel locating tools created to the same functional dimensions as the OEM equivalents. They replace many factory reference numbers so you don’t need separate special-service-tools for each job.

• Contains camshaft alignment pins, crankshaft/flywheel lock and tensioner tools.
• Compatible with OEM refs: 303-1097, 303-1550 and many related numbers.
• Machined contact points match factory locating positions for repeatable timing.
• Compact case keeps tools organized and protected between jobs.

How does the kit improve workshop efficiency and accuracy?

Using purpose-fit locking tools reduces the chance of belt slip or valve damage when the timing system is disturbed. The kit’s precision fit minimizes movement while you replace belts, tensioners or camshaft phasers, helping technicians work faster and with greater confidence.

• Prevents rotation of crank or cam during disassembly and reassembly.
• Speeds up timing alignment compared with improvised methods.
• Reduces risk of engine damage from incorrect timing positions.
• Saves time when servicing multiple vehicle models thanks to broad fitment.

Are there any fitment or usage tips to keep in mind?

Before using the tools, confirm your engine code and reference the vehicle’s service manual for the exact locking positions and torque specs. Use the correct tool from the kit for each locking point and store the set in its case to avoid wear on precision faces.

• Verify engine code (e.g., FYDA, HWDA, EDDB) against compatibility lists.
• Follow OEM procedures for setting TDC and locking phasers before removal.
• Do not force a tool into position; check orientation and seating first.
• Clean locating holes and shafts before inserting pins to ensure accuracy.

Who this is for: The Yuesstloo Engine Timing Tool Kit is aimed at independent mechanics, dealership technicians and experienced DIYers who work on Ford, Mazda, PSA or Volvo engines listed in the fitment information. If you service timing belts, timing chains with phasers or VVT/VTC components on the covered engines, this set supplies the right locking tools to finish the job accurately and safely.
