Tool Type:

Parts Used:
Press.Sw.4W 3/8In Valve Ul - AB-9063096
Pressure Reducer - AB-9051116
Repair Difficulty:
Medium
Time Spent Repairing:
More than 2 hours
Tools Used:
Screwdriver, Pliers, Wrench Set, teflon tape, new fittings between switch and reducer, vise.
There was not what you would call a problem. the fittings are glued so as not to leak this made them very hard to remove.
Two things to be aware of for this repair:
1. Replace the fitting between the switch and reducer, if I would have known this I would have ordered it with the other two parts. This fitting as are the others are very difficult to remove, the glue and the amount of torque used to install them really contributes to it. I removed the switch from the compressor and mounted it in a vise by the metal part of it to remove.
2. Where the pressure tube goes into the switch there is a release which allows you to remove the fitting the tube goes into, this makes it easier to remove the tube.
But it's done and works great, I'm glad eReplacement parts was available, they had the exact replacement parts and priced very reasonably. I'm gonna have to keep them in mind.

Adjustable pressure reducer knob stripped threads
I found that in order to replace the entire pressure reducer assembly that includes the reducer and threaded knob, that it needed to be removed from the compressor. I found it easier to just remove the old damaged part from the compressor, remove only the new threaded pressure reducer knob from the new part and put it on the old assembly. I did not have any thin open ended wrenches to take the entire assembly off of the compressor. I just removed the old stripped out pressure part and replaced it with just two adjustable wrenches and some channel-locks. Did not want to have to buy any new tools or replace any parts that were not broken. Start to finish less than 10 minutes. Now I can once again adjust the hose pressure.

Adjusting knob had broken off.
1. Took off the pressure regulator assembly. This has to be done to allow room for the adjusting knob as the pressure reducer is screwed in.
2. Screwed on the new pressure reducer.
3. Screwed on the outlet assembly.
4. Screwed on the pressure gauge.
5. Reinstalled the pressure regulator assembly.

Would not turn on
To replace the pressure switch, I removed the parts that do not come with the new pressure switch. I removed the cover and noted how the wires were connected. Then remove the old pressure switch and installed the new one. I wired it the same as the old one , then installed the new pressure guage on it. I then connected the new pressure reducer to the switch, and used the parts from the old one and put them on the new one.

Pressure Regulator knob on the compressor broke off.
Removed the old pressure regulator after first taking off the pressure gauge and the head of the regulator so that it could be unscrewed from the body of the regulator pressure switch.
Replaced in the same way by first installing the new part less control knob and pressure gauge and then adding these two components and finally connecting up the air line on the downstream side of the unit.

    Parts for compressor
    Ordered the exact parts by model for my compressor, delivered in just a few business days and was an east repair! Voss for the parts were more than fair! Will use this for all my needs!

    Perfect fit
    The part fit perfectly as compared to the part I purchased from a major online retailer. It is hard to fit a toy Dingo into a compressor. I also like that one of the repair instructions suggested replacing the double screw and the gauge. Doing that made the whole job much easier.
