Lucas Cav Simms Shaft Bushing 501849 for Simms Minimec Injection Pumps.

Simms / Lucas CAV 501849 Shaft Bushing | Minimec Inline Injection Pump Replacement

Restore precision tolerances and smooth mechanical operation to your Simms inline fuel injection pump with this replacement shaft bushing (Part # 501849).

Over thousands of operating hours, internal governor and control shaft bushings are subjected to continuous vibration and mechanical cycling. Excessive radial play or oval wear in these bushings leads to sloppy governor response, erratic idle, surging, and difficulty holding calibrated rack positions. Installing a fresh, precision-machined 501849 bushing eliminates unwanted backlash and ensures rigid, accurate shaft alignment during bench calibration and heavy field operation.

Key Features & Benefits
Eliminates Shaft Slop & Play: Restores factory clearance for critical internal shafts, preventing governor hunting and uneven fuel metering.

Precision Machined Tolerances: Manufactured to exact OE specifications for a secure press-fit into the pump housing without galling.

Heavy-Duty Wear Resistance: Engineered from high-grade bearing bronze/alloy to withstand sustained mechanical friction and engine vibration.

Essential Rebuild Component: A critical replacement part during complete overhauls, reseals, or governor servicing on Simms Minimec pumps.

Specifications & Applications
Part Number: 501849 (Cross-reference: 23330)

Pump Series: Simms / Lucas CAV / Delphi Minimec Inline Diesel Injection Pumps

Common Engine Applications: Ford / New Holland (e.g., 2700 series, 5000, 7000 series tractors, marine conversions), Perkins, Leyland, Case, and industrial power units equipped with Simms inline pumps.

Condition: Brand New

Rebuilder's Note
Ensure the bore in the pump housing is thoroughly cleaned and inspected for scoring before pressing in the new bushing. When installing, use an appropriately sized arbor or bushing driver to apply even pressure across the face to prevent distorting the internal diameter. Always verify proper shaft clearance and free, uninhibited rotation after press installation.
