This compact designed timing tool will time all PT type Cummins engines. Comes packaged in a sturdy blow molded case.This tool will not work on the Cummins B, C or ISX series engines.
The M20070 Cummins Timing Tool is a professional-grade engine timing and alignment fixture engineered to provide precise synchronization of the camshaft, crankshaft, and front gear train components on Cummins heavy-duty diesel engines. This tool is essential for technicians performing major overhauls, timing gear replacement, camshaft service, or any repair procedure where factory-correct timing relationships must be verified or re-established.
Built from hardened, shop-grade steel, the M20070 is designed to withstand repeated use in demanding diesel engine rebuild environments. It locks components into exact alignment so the technician can confidently assemble or re-time the engine without risk of misalignment that may lead to performance loss, excessive fuel consumption, starting difficulty, or catastrophic internal damage.
This timing fixture eliminates guesswork by providing the rigid support and positioning required for OEM-spec timing accuracy. Whether used during full teardown and rebuild, cam and crank gear replacement, timing cover repairs, or injector timing adjustments, the M20070 ensures consistent, repeatable precision across all service procedures.
Why Proper Timing Matters
Incorrect cam-to-crank timing on a Cummins engine can result in:
-
Valve-to-piston contact
-
Fuel injection events occurring too early or too late
-
Hard starting or no-start conditions
-
Rough idle or loss of power
-
Poor fuel economy
-
Premature camshaft, follower or gear wear
The M20070 prevents these issues by providing the exact alignment points required to re-establish correct timing.
Key Features & Benefits
-
Precision alignment tool designed exclusively for Cummins heavy-duty diesel engines.
-
Locks camshaft and crankshaft in precise position to restore original OEM timing relationships.
-
Prevents costly engine damage associated with timing errors, including valve interference and gear misalignment.
-
Essential for front gear train service, camshaft removal/installation, timing cover repair, and injector calibration procedures.
-
Reduces labor time by eliminating time-consuming manual measurement or approximate alignment.
-
Durable hardened steel construction, ensuring long service life in professional rebuild facilities.
-
Supports consistency and accuracy across repeated rebuild cycles and timing verification checks.
-
Compatible with in-frame and out-of-frame overhauls, ideal for fleet maintenance and engine remanufacturing operations.
Typical Applications
Use the M20070 during:
-
Camshaft installation or replacement
-
Crankshaft or gear train service
-
Timing gear housing repairs
-
Full engine rebuilds (NT, NH, N14—depending on model specification)
-
Injector and fuel timing verification
-
Preventive maintenance requiring timing inspection
