0 blackdog2 Posted April 29, 2016 Share Posted April 29, 2016 (edited) Yup a large o- ring big job they get hard and flat and leak. does your air system have a lot oil in it and leak out through the air leak Edited April 29, 2016 by blackdog2 Quote Ed Link to comment https://www.bigmacktrucks.com/topic/45030-puff-limiter-cylinder-housing/#findComment-331884 Share on other sites More sharing options...
0 br549 Posted April 29, 2016 Share Posted April 29, 2016 Like black dog said oil can be coming from the little pin hole in the puff limit cylinder as the air goes in and out if your air system has oil in it. There is a o-ring around the housing that let it turn seal off the oil. I have taken and clean the area real good after putting the cylinder back in and putting rubber glue around it and letting it dry real good before running it and usually works. Other than that you must remove pump to replace. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/45030-puff-limiter-cylinder-housing/#findComment-331889 Share on other sites More sharing options...

0 Village farms Posted May 13, 2016 Author Share Posted May 13, 2016 How many gallons/quarts of oil is the em6-300 supposed to hold? Quote Link to comment https://www.bigmacktrucks.com/topic/45030-puff-limiter-cylinder-housing/#findComment-333203 Share on other sites More sharing options...
0 j hancock Posted May 14, 2016 Share Posted May 14, 2016 EM6 300 with "ESI" takes 28 quarts (two oil filters and small pan) and EM6 300 with "ESI Plus" takes 51 quarts (three oil filters and large pan). 1 Quote JimIt doesn't cost anything to pay attention.

Question
Village farms
I found my puff limiter cylinder leaking on my American Bosch pump and have ordered a new one.
My truck had a bad oil leak and it seems to be coming from the housing the puff limiter screws in to. I can rotate the housing with my hand.
Is this normal? And if not, do I have to pull injection pump to repair/replace.
Any help appreciated.
