Thread: AMK compressor Repair Kit

I decided to change the desiccant, O-rings and exhaust valve solenoid on my compressor today. It's done 180,000km but the desiccant showed little sign of degradation, one of the filters may as well be new and the other a little dirty but definitely not blocked. I'd be surprised if I couldn't have gotten another 100,000km out of it. but I went this far so changed it all anyway.

That desiccant looks more like molecular sieve than the conventional silica based stuff. Interesting.

the desiccant I replaced it with (from 4x4AirSeals) looks essentially the same only larger beads - they say to be less obstructive but presumably less surface area means less effective.

Hi Macadamia,
The compressor and mount assembly is much easier to refit if you slot the top mounting hole in the bracket horizontally and start the bolt before fitting. The bolt will then support the whole assembly while you get the 2 bottom bolts in.

I’ve read that a few times but I had no trouble getting it back in. It was easy to fit the bottom two bolts then fiddle the top one into place and tighten with a ratchet spanner.

Depends a lot on dexterity I suppose. I read about it in another post so did it, found it made the job quite easy.

For the AMK compressor the bracket doesn't need to be removed from the chassis.
Simply undo the 4 compressor mount bolts collecting the springs and washers then slide the compressor rearwards and angle it out.
Remove the hose and electrical connections first, of course.

Could I ask a part number on the valve solenoid?

The suspension error I'm getting is about not venting quickly enough - the compressor itself is definitely pumping up very well, my mechanic is pretty sure the problem is the exhaust valve (or solenoid - is there a difference?).

My GAP IID is telling me it's a Hitachi compressor, but I gather that doesn't necessarily mean that's what is actually on the car?

Are the black plastic parts of the compressor different on AMK and Hitachi (and Dunlop etc) or is it just the motor/compressor itself?

What's the chances there's a good person on the forum with a changed out valve body they're willing to part with? (he says on knees with hands clasped)?

Thanks in advance...
