E-cowlboy Injection Pump Gear Puller & Cummins 3‑Piece Service Kit — 1989–2002 Dodge Ram, Forged Steel Tools

E-cowlboy's kit combines a heavy-duty injection pump gear puller, an engine barring/rotating tool, and a 13mm injection-pump/idle-nut wrench built for 1989–2002 Dodge Ram Cummins diesel engines.

This three-piece service kit was designed for technicians and hands-on owners who maintain Cummins B, C and 4BT/6BT platforms and Bosch VE, P7100 and VP44 injection pumps. Each tool addresses a common workshop task—removing a seized pump gear, rotating the crank safely for adjustments, and accessing tight 13mm pump mounting or idle lock nuts. The components are forged and machined for repeatable performance and minimal front-cover interference during removal.

How does the gear puller make pump removal safer and faster?

The heavy-duty injection pump gear puller pulls the gear without contacting the engine front cover, preventing damage while providing a straight, controlled extraction. It uses two flange bolts (M8x1.25) for secure attachment and a central forcing screw to deliver consistent pull force.

• Designed for Bosch VE, P7100 and VP44 pumps.
• Fits Cummins 4BT and 6BT pump gears.
• Zero contact with the front cover to reduce repair risk.
• Requires two M8x1.25 flange bolts (user-supplied).

How does the engine barring tool speed valve and timing work?

The engine barring/rotating tool engages the flywheel ring gear so you can rotate the engine precisely using a 1/2" square-drive ratchet or breaker bar. It makes tasks like valve lash checks, timing adjustments, and turning the crank much quicker and safer than improvised methods.

• Works on Dodge 3.9L, 5.9L, 6.7L and 8.3L diesels and Cummins B/C series engines.
• Heat-treated 42CrMo steel for strength and tolerance.
• Insert into flywheel housing until it engages ring gear.
• Attaches to a 1/2" drive ratchet or breaker bar for controlled turns.

When should I use the 13mm injection pump and idle nut wrench?

The low-profile 13mm wrench is made to reach confined pump mounting bolts and idle lock nuts on Cummins B-series 5.9L applications. If you need to remove or install 13mm pump bolts in tight engine bays, this tool provides the access and leverage many standard sockets and open-end wrenches can’t.

• Specifically fit for Cummins B-series 5.9L engines in Dodge trucks.
• Low clearance design for cramped mounting areas.
• Also handy for other 13mm fasteners in confined spaces.
• Compact dimensions: approx. 0.5" H × 4" W × 8" D; 0.4 lb weight.

What’s included and how do I prepare to use the kit?

The package contains the gear puller with two heavy-duty flange bolts, the engine barring tool, and the 13mm wrench. You should supply the M8x1.25 flange bolts if your pump does not have them and have a 1/2" drive ratchet or breaker bar available for the barring tool.

• 1× injection pump gear puller (with two flange bolts provided).
• 1× engine barring/rotating tool (42CrMo steel).
• 1× injection pump & idle nut 13mm wrench.
• Recommended accessories: M8x1.25 bolts (if not present), 1/2" drive ratchet or breaker bar.

Who is this for: This E-cowlboy kit is aimed at professional mechanics, diesel truck shops, and skilled DIYers who work on 1989–2002 Dodge Ram Cummins engines or similar Cummins B/C and 4BT/6BT packages. It’s practical for routine pump servicing, timing work, valve adjustments, and any job requiring secure gear removal or precise engine rotation.
