Mog losing air/air not building up

[combined tree services]

:thumbdown:hiya guys , have got a problem with my mog that it is not bulding enough air and what air is built is lost verry quickly . I have noticed this yesyerday out on site but has got worse over yesterday and today , when i got it back to the yard this afternoon i emptied the air tanks and not for some reason the compressor will not charge the tanks at all , hopefully some of you have some ideas of she may well be going for a long trip on a low-loader one way

maybe compressor cylinder head is carbon ed up if so you can get a repair kit

or trailer brake connector may not be sealing properly

or the pressur relif valve needs cleaning out

Welcome to the joys of mog ownership mate lol

the strange thin is that this has only come to light since we put the chipper on the back , we had the mog working all day today and not once did the mog tanks fill and the pressure relief valve activate , it has slowly got worse yesterday and toady ,

i had no end of probleoms with my air on my mog the air presure relif valve was always blocked when and brought a new one in the end

listen for leaks, check the compressor belt is tight, usually air hoses go where they are rubbing on other hoses or metal, check the seals around the compressor.

did it have enough air to turn itself off?

air are mogs downfall imo, when this started with mine it ended up costing me over 2k in parts and 3 months of head aches, that mog will be at that age where it moght need redoing all the valves and pipes, start at the tanks and work your was around. there is a big pipe from the compressor to the tanks, take it off and if its iss full of solid looking gunk then take off the other end and blast it through with a big compressor, but all your valves will be carboned up and need seriously cleaned out, then you will have to do all the other pipes and valves, major ball ache and costly. it could just be the cylinder head gasket in the compressor, the kit is buttons but the head might need reskimmed. worth getting it checked before you put a new one on, guess how i know this lol. sounds like the pto might be rubbing a pipe though, i would check behind the cabm their is a t-piece in their the size of your standard brewery compressed air pipes the same as a pub, it comes out a valve under your seat in a 10mm pipe, then crosses over the pto, if he has been front mount chipping that could be full of chip and pushed the pipe down toward the pto, this could be the problem

 

 

i would check there first, ha ha. it just came to me as i was typing lol
