Description
When you start hearing that knocking noise from your injection pump drive, don’t ignore it—that’s your buffer cushion telling you it’s time for replacement before expensive pump damage occurs. This rubber component absorbs the shock loads between your engine and injection pump, protecting both components from the hammering that develops when the rubber deteriorates. A worn buffer doesn’t just make noise; it can destroy pump drives and timing gears, turning a simple replacement into a major repair bill.
What You’re Getting
- Precision-molded rubber that absorbs drive shock between engine and injection pump
- Direct replacement designed specifically for Fordson Major and Super Major models
- Works in conjunction with coupler assembly 43141 for complete drive protection
- Prevents metal-to-metal contact that damages expensive pump components
- Restores smooth, quiet injection pump operation your tractor was designed for
Built for Classic Fordson Workhorses
Your Fordson Major series represents reliable 45-95 HP workhorses known for their dependability, but their mechanical injection systems have zero tolerance for contamination or drive shock. Whether you’re running hay equipment, pulling cultivation tools, or doing loader work around the farmyard, this buffer sits between the engine’s power pulses and your injection pump’s precision components. When this simple rubber part fails, you’ll hear it immediately—a harsh knocking that gets worse under load.
Made to Last
This buffer might look simple, but it’s engineered to handle the specific loads and frequencies of your Fordson’s diesel engine. The rubber compound maintains flexibility while resisting the oil and heat found around injection pump drives. The molded design provides exact cushioning characteristics—soft enough to absorb shock, firm enough to maintain precise pump timing.
Installation Notes
Replacing this buffer typically requires removing the injection pump, so budget 2-3 hours for the complete job. Mark your pump position carefully before removal to maintain timing. While you have access, inspect the coupler assembly (43141)—if the buffer failed, the coupler probably needs attention too. Clean all mating surfaces thoroughly since any debris causes premature failure.
