I was checking the valves on my WR426 and I can't get 2 of the buckets housing the shims out. 3 came out fine and the last 2 rotate freely but will not come up. Any ideas? Thanks

Probably worn a groove in the carrier. Try using propane torch to quickly heat up the carrier around the buckets and tap them out from the top with a piece of plastic. You should measure all of this with micrometer to verify wear.

Nah man, waste of time.

Just use long nose pliers to get a grip on the caps to lift them up. :bonk:

The buckets should always come out smoothly using a magnet. The only stuck ones I have seen were due to the cam bearing journals being severly worn. The damage can have a mushroom affect that will obstruct the bucket bores and not allow the bucket to be removed until you clean up the worn material. If this is the case, a good machine shop should be able to refurbish the head for you.

Good luck,
Scott

Ah, yeah. Magnet. :bonk: I did like Mutu and just used needlenose pliers with teeth very carefully so I didn't scratch anything. I figure the bucket is extremely hard metal.

Next time I'll grab a magnet.

Yeah, the bucket is really hard and durable. You won't be able to scratch it. It's the oil that makes them stick.
