Replace worn or missing felt throttle shaft seals on Keihin PD carburetors. These felt seals are used during carburetor service or restoration to help...
Check a float and its pin separately from bowl drain hardware or shaft seals. Package contents and the fitted carburetor design matter more than a shared category label.
The float includes its pin. The drain screw includes its O-ring and is sold individually, so count the affected bowls before setting the quantity. Inspect mating surfaces as well as the removable parts; replacing a screw alone does not assess the condition of its seat.
Confirm the shaft-seal job before buying
The twelve-piece felt set covers throttle and choke shaft-seal service on compatible constant-vacuum carburetors. Compare the fitted carburetors and seal locations before dismantling. Do not choose a different felt-set size merely because another part listed for several models appears nearby.
Ordering questions
Does the float-and-pin package also replace the fuel shut-off parts?
It contains one float and its pivot pin, without the float-valve needle, seat or bowl gasket. Four floats are used across the rack, but inspect each carburetor and its valve components separately before deciding the order quantity.
What if the bowl drain still leaks after replacing its screw or O-ring?
Inspect the screw tip, O-ring groove, bowl seat and surrounding bowl for damage or debris. A new seal cannot repair a damaged mating surface. Avoid using extra tightening force to mask the leak; it can damage the screw or bowl.
How many felt seals are in the featured set?
Twelve felt seals are supplied. Confirm the compatible throttle and choke shaft locations on your carburetors before ordering; the piece count does not by itself identify every seal position.
