Discussion Overview

The discussion revolves around finding a replacement v-pulley for a high-pressure air compressor in Japan. Participants explore potential sources for the pulley and discuss alternative drive options for the compressor.

Discussion Character

  • Technical explanation, Debate/contested, Experimental/applied

Main Points Raised

  • One participant seeks a source for a replacement double V-belt pulley for a 500 psi air compressor.
  • Another participant suggests checking McMaster-Carr and Grainger for replacement parts, noting potential additional shipping costs for overseas orders.
  • A third participant recommends Globalspec as a resource for finding links related to the required pulley.
  • One participant proposes that substituting different drive mechanisms (like chain drive or single-V) could be viable, as long as the general ratio is maintained, and mentions that 500 psi is not particularly high for compressors.

Areas of Agreement / Disagreement

Participants generally agree on the need for a replacement pulley and suggest various sources, but there is no consensus on whether to maintain the original double-V configuration or consider alternative drive systems.

Contextual Notes

Participants express differing views on the necessity of keeping the original pulley type, indicating that the discussion may depend on specific performance requirements and design choices.

Who May Find This Useful

This discussion may be useful for individuals looking to repair or modify high-pressure air compressors, particularly those interested in sourcing parts or exploring alternative drive mechanisms.

I am in Japan and recently acquired a salvage high pressure (500 psi) air compressor. It was junked because the large spoked flywheel v-pulley on the compressor had broken. The pulley is cast iron, about 15", double V belt, keyed shaft about 1.25'.

Could you suggest a source for a replacement of such a v pulley?

(Power for this unit is a Kohler 12 HP electric stat engine ... runs perfectly. Would like to get this unit up and running again.)

Thanks,

E Lee

Check into McMaster-Carr, http://www.mcmaster.com/ or Grainger http://www.grainger.com/Grainger/wwg/start.shtml

You can also try W.M. Berg. Here is a worksheet you can fill out and fax to them and they will see if they can match what you need: http://www.wmberg.com/faxbelt.html

I'm sure you'll have to pay a bit more for overseas shipping.

Some very good links there.
 
Keep in mind as well that just because the thing started with a double-V pulley is no reason to keep it that way. Feel free to substitute a chain drive, gears, Gilmer drive, single-V, etc., as long as you keep the same general ratio that it's designed for. 500psi is not actually very high for a compressor, so you shouldn't have to worry too much about tolerances. (A little pocket-size 12 VDC automotive compressor goes up to 300 psi; heavy-duty home types can hit 2500, and I don't even know what the upper limit for industrial models is.)
