871. Air compressor - Bigstank - 09-01-2017 Can someone tell me if the air compressor is going bad. It's clicking loudly while building air. When it hits 120psi and purges it stops. Thx RE: 871. Air compressor - Bigstank - 09-01-2017 Oh and also the truck holds air pressure just fine no leaks or no oil leaking from the compressor. RE: 871. Air compressor - Tanker93 - 09-01-2017 I remember a few year ago we had one making a horrible ticking sound and all I did was replace the air dryer filter and she was all G. Not saying this is definety it but hope it helps. RE: 871. Air compressor - Waterloo - 09-01-2017 Is the air compressor clicking or is the air dryer clicking? As far as the air compressor on an ISX, they have an air compressor rebuild kit. Basically a new head and gasket, runs around $500, much cheaper than a full compressor by quite a bit and will cure most issues. It is rare for the air compressor to actually fail. It happens, but again it is rare. Normally, the air compressor "knocks" or makes a "hammering" sound, and sounds like sheet, but normal. Clicking though, is normally the air dryer, they have kits to rebuild or replace with a new one. Which model/brand truck do you have, I forget. On the ProStar, the air dryer is under the cab, so it would be easy to differentiate between the two units. I have seen some trucks where everything is right there together, the reason I ask. But, if it is the air compressor, I would check the bolts holding the head on the compressor itself to see if any are loose. There is a tightening procedure and torque specs on Quickserve. Sounds like maybe the compressor head gasket may be the issue it it is the compressor clicking, that is where I would start. |
