How to find the right Automotive Replacement Distributor Bushing Bearings AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Automotive Replacement Distributor Bushing Bearings
- Exact shaft and bore fit
- Match the bushing inside diameter to the measured shaft diameter and the outside diameter to the housing bore. Install, then size by reaming or honing if the supplier calls for it. A press-fit bushing closes up when installed, and a loose bushing leaves the play you were trying to remove.
- Replace in pairs
- Replace the upper and lower bushings together. Shaft side play comes from the combined wear, and one new bushing cannot keep the shaft true on its own.
- Shaft condition
- Inspect the shaft for scoring or wear where it rides in the bushings before you buy bushings. A worn shaft keeps the wobble even in new bushings.
- Material and lubrication
- Oil-impregnated sintered bronze is standard. Pre-oil it, and keep the oil wick or oiler topped up where fitted. Dry bushings wear quickly and cause erratic dwell and timing.
Brands that matter
- Standard Motor Products: Carries rebuild parts for many older distributors.
What to avoid
- Rebushing a distributor whose housing bore is oval or cracked.
- Hammering bushings in without a proper driver, which distorts them.
Questions
How do I know the bushings are worn?
Side-to-side play in the shaft, a rotor that wobbles, or points dwell that changes with rpm are the classic signs.
