Throttle spindle shaft seals for Lucas/CAV diesel pumps. Fits DPA, DPC and DPS pumps. These also fit the fuel shut-off shaft on DPA and DPC pumps (sold in pairs)
These O rings often perish and wear with age, symptoms of seal failure include poor starting (often requiring hand priming – particularly in cold weather), a reduction in fuel economy, visible diesel leakage around the throttle shaft. Fortunately, they can be replaced without removing the pump from the engine. We can supply both NBR and Viton O rings
If you require the throttle shaft itself, or the top gasket, these are also available separately and as a kit.
