  • check the vacuum level - Should be 11 or more while on the cow or the pulsator won't work. Vacuum leaks, worn out pumps or too small of pumps are common causes of the pulsator not working.
  • check the vacuum hose.  if it is blocked, the pulsator will not work
  • check the slides - on P and C models the front and rear slides are different and if switched, the pulsator won't work
  • Do Not oil the block - only the leathers

    My local supplier was selling this kit for 50$. Found this product on-line and it was shipped across the border to my farm (Ontario, Canada) within 1 week for half the price. Great service!

    Needed more directions. This was the first time I tried to repair the pulsator. Kit was complete and saved me from having to purchase a new pulsator. Would highly recommend.
