Wolf air 50

[jb57uk]

Hi all need some advice Ive got a wolf air apache 50 2hp 50 ltr compressor
its about 6yrs old , When you turn power on (elec) it runs continually also
it will only fill to about 4bar 65lbs ? I have drained tank and looked for leaks=none, It will run on until I switch off power,,,?thanks

Sounds like one of the valves in the pump is faulty. After you switch it off does the pressure decrease or hold? Can you hear air coming out of the inlet?

 

[jb57uk]

Hi Pressure holds and cannot see or hear any air leaks,

 

[rtbcomp]

Is the air filter blocked? If not most likely the inlet valve not closing properly.

 

[jb57uk]

filter clean, what do you mean by inlet valve ?

 

[rtbcomp]

It's in the cylinder head of the pump and is sucked open when the piston moves down to let air in.

stripped head off had a look at cylinder sleeve bit scored

Any chance of some photos?

 

[jb57uk]

In the bottom right is the reed bent slightly? If it doesn't close properly it will prevent a full charge of air entering the cylinder on the downward stroke, assuming it's the outlet valve.

The bore also looks excessively scored, that could be part of the cause.

Hi yes the reed is bent , and the liner is scored, can parts be sourced for this model ?
and is it worth it ?

 

[rtbcomp]

Don't know - doubt it.

The whole Wolf setup is rather complicated, these people may be able to put you in touch with someone who may be able to help.

You might be able to bend the reed back or even make one, nothing to loose.

One-piece, oiless pump/motor; not worth fixing IMO.

You could get another direct drive pump off ebay. That is what I did.
