Yamada 771337 Guide for NDP-15

The Yamada 771337 is a factory guide used in NDP-15 Series pumps. It is a wear part by design - it is meant to take the wear so that the machined housing around it does not.

Contamination is what wears bushings. Moisture from the air supply and product from a failed diaphragm both find their way into the bore, and both turn a clean sliding fit into an abrasive one.

Frequently Asked Questions

Q: Should both bushings be replaced together?
Where the pump uses a pair, yes. They share the same shaft and the same hours, and an uneven pair pulls the shaft out of line.

Q: Does it need lubrication?
Follow the factory instruction for the model. Where grease is specified on the shaft, assembling dry shortens the life of the bushing and the seal together.

Q: How do I know the bushing is worn?
With the shaft in place, try to rock it across the bore. Any noticeable movement means the guide clearance has opened up. Where the factory publishes a usable range, measure against it rather than judging by feel.

Q: Can I fit new seals and leave the bushing?
It is the most common false economy in this job. A worn bushing lets the shaft run off center and the new seal wears on one side straight away.
