Detailed fuel pump timing procedure for Cummins ISX15 / X15 using ATC 5572562 tool.
This 12-phase procedure uses the ATC 5572562 tool to time the fuel pump gear train on Cummins ISX15, X15, and QSX15 engines. Ensures accurate alignment during XPI / Next-Gen pump service for optimal performance.

Introduction: Essential Fuel Pump Timing for Cummins Engines
Accurate timing of the fuel pump gear train in ISX15/X15 prevents noise, power loss, and wear. The ATC 5572562 tool, OEM 5572562/5572664 replacement, locks alignment—key for reliable service.
Phase 1-3: Engine Preparation & Access
- Secure engine and remove components – Gear housing access
- Inspect gear train – Note timing marks
- Remove old pump if needed – Clean area
- Prepare ATC 5572562 tool – Verify condition
- Align pump drive – Initial position
Phase 4-6: Timing & Locking
- Insert timing tool – Lock pump gear
- Align camshaft marks – Match factory spec
- Verify synchronization – No play
- Torque pump fasteners – Per sequence
- Check alignment again – Confirm lock
- Remove tool carefully – No disturbance
Phase 7-9: Reassembly
CRITICAL: ATC 5572562 Timing Setup
- Reinstall housing/components – Torque spec
- Prime fuel system – No air
- Check timing marks – Final verification
- Document alignment – Photos/notes
- Refill fluids – Check levels
- Reassemble covers – New gaskets
Phase 10-12: Testing & Finalization
- Start idle test – Monitor noise
- Road test load – Verify performance
- Final inspection – No leaks/rattle
- Schedule follow-up – At 1,000 miles
Critical Safety Warnings: Timing Procedure
MUST AVOID THESE FATAL ERRORS:
- ❌ Never misalign tool – Gear damage ($3K+)
