Product Description
The Cummins 3931569 OEM P7100 Linkage Bell Crank Lever is a genuine throttle/fuel control lever used on the Bosch P7100 injection pump found in 1994–1998 Dodge Ram 2500/3500 5.9L 12-Valve Cummins trucks. This bell crank lever transmits throttle input to the P-pump's fuel control arm, making it a critical component for proper response, idle stability, and power delivery.
If your OEM bell crank is worn, loose, bent, or damaged during pump service, replacing it with genuine Cummins hardware ensures correct geometry, smooth throttle motion, and long-term durability—especially important on performance-modified 12-valve trucks running higher fueling rates or upgraded governor springs.

FAQ
What does the Cummins 3931569 bell crank lever do?
It transfers throttle pedal movement to the P7100 fuel control arm, regulating fueling and engine response.
Is this lever the same for all P7100 pumps?
No. While many automotive P7100s use this lever, industrial and off-road pumps often use different linkage. Verify by pump tag number if unsure.
Does a worn bell crank lever affect throttle response?
Yes. Wear or distortion causes sloppy throttle feel, delayed fueling, poor idle stability, and reduced control.
Should this lever be replaced during governor spring or pump tuning work?
It is recommended. When servicing the pump, replacing worn linkage ensures accurate lever motion and prevents future failures.
