Yuesstloo Cam Timing Tool Kit + Engine Brake Adjustment Tool, 16‑Piece for Cummins 2007–2017 — CNC Hardened Steel

Yuesstloo's Cam Timing Tool Kit with Engine Brake Adjustment Tool is a complete 16-piece set built to align camshaft timing and adjust Jake brake screws precisely on Cummins diesel engines from 2007–2017.

If you work on heavy-duty Cummins engines—ISX (2016–2017), QSX, X15 or earlier 2007–2012 dual-cam models—this kit gathers the specialty pins, wedges, crank pin, cam-gear puller and a feeler gauge needed to set gear train timing and fine-tune exhaust brake contact points. The tools are CNC-machined from hardened steel, packaged in a compact case with gloves, and designed to match OEM dimensions for repeatable alignment and adjustment tasks.

How does this kit help set camshaft timing correctly?

The kit supplies the crank pin, cam gear puller and wedge sets required to lock components and define the correct gear-train relationship during assembly or service. Using the wedges and crank pin prevents unintended rotation while you install or inspect timing gears.

• Includes 4°/5°/6°/7° wedges to match single- and dual-cam setups
• Crank pin secures crankshaft position for accurate timing
• Cam gear puller removes gears without damaging the hub

What tools are included for Jake brake and exhaust adjustment?

The set contains a Jake brake tool (7mm feeler gauge) plus washers and screws to access and adjust exhaust valve contact points between slave pistons and the adjustment screw. This lets you set the brake clearance consistently across cylinders for even operation.

• 7mm feeler gauge for consistent gap measurement
• Adjusting screws and washers to secure calibrated settings
• Wedges to maintain cam timing while adjusting brake components

Which engines and years are compatible with this kit?

The Yuesstloo kit is made for a wide range of Cummins diesel engines produced between 2007 and 2017, including ISX models (2016–2017), QSX and X15 families. The 6° wedge is specially sized for 2007–2012 dual-cam engines, and the kit lists OEM-equivalent part numbers to help confirm fit.

• Compatible with Cummins 2007–2017 engines (ISX 2016–2017, QSX, X15)
• OEM-equivalent numbers: 3163020, 3163021, 3163069, 3163530
• Dual-cam wedge (6°) tailored for 2007–2012 dual-cam setups

Are these tools durable and precise enough for workshop use?

Each piece is CNC-machined from heavy-duty steel and finished for corrosion resistance and high hardness, delivering workshop-grade durability and dimensional accuracy close to OEM parts. That combination reduces the risk of deformation during leverage, keeping timing and brake adjustments reliable over repeated jobs.

• Hardened steel construction resists wear and bending
• Precision machining for accurate fit and repeatable results
• Compact carrying case and included gloves for onsite work

Who is this for: technicians, fleet mechanics and do-it-yourself diesel enthusiasts who service Cummins heavy-duty engines will appreciate this all-in-one timing and brake adjustment kit. It suits garages that need a portable, OEM-equivalent set to handle camshaft timing, cam-gear removal and Jake brake clearance work across multiple Cummins models and model years without repeatedly sourcing individual specialty tools.
