Maybe an optical illusion but in the first pic I can see a curve in the belt where it leaves the small pulley.
If so belt is too loose. Not sure why it has a problem turning if you tighten it but keep working on it to get it right, that compressor will be much better than the direct drive ones.

Droog u are correct mate this belt is a dunlop belt i went to Pilot Airs service center in Sydney shortly after i bought the compressor i took in the old belt and the bloke who served me took the money than said he had to go down the road to get the belt he came back 20mins later with this belt, pilot air has 2 factories 1 street apart so he may have gone to the other factory but i must say this belt is quiet stiff from day 1

It makes a surprising difference.

Comp is running a dunlop match vee belt i just went out to the shed to check the play between pulleys its about 15mm possibly 20mm i read the recommended is 10-12mm so i think the compressor may be fixed
I will first try to tighten the belt the tinest movement if that fails i will get a can of that magic
This is my first electric belt compressor my only other belt compressor was a hafco 100L honda petrol powered compressor and that thing i could run a dust gun at 90psi continously for as long as i wanted so u can imagine when i hear my little pilot air compressor it just sounds weak like no omph to it

Looking at the video and the picture the belt sorta looked like it was a blue colour, which if it is then it's most likely a kevlar belt which are stiffer than your average black rubber belt and unsuitable for an air compressor. (kevlar belts do come it some other colours). You shouldn't need a cogged belt unless the motor pulley is 3" and below. The belt is definitely too loose, all the same I would try another belt as it sounds like it's too stiff if the pulleys won't turn when it's tightened.

Go with a new belt. Full V section, gives more contact area.
Make sure the pullies are in line. Use a straight edge.
Don`t over tension the belt. Too much load on the motor or comp bearings will damage them.
CRC belt grip, great diagnostic tool. For multi belt setups it was great for spaying some on each belt until you find the noisy one. Handy but not a long term solution.

Forgot,
Can you take a pic of the motor drive pulley looking down into the V section. The belt appears to be sitting low in the pulley, might be worn after years of squealing.

The compressor is finally fix and works awesomely finally lol, i had to jamb a piece if 50x50mm alloy in between the motor and pump to push the motor a part to get the correct tension on the belt, i ran my hose directly to the tanks outlet no extra fittings or joints just strait to a barb fitting i put a new fitting on the end of the hose and everything is air tight except there is a very tiny leak from the one way valve where it screws into the tank i need to address also the copper air delivery hose was originally bent when i bought the compressor and yesterday i kinked it more than bent it back a little and it put a small 1mm hole in a crease it only leaks when it is filling up can i use ordinary electrical solder? i tried to use one of those fan dangle low aluminium welding rods to fill the hole but its crap
also think my pulley on the motor is worn will upload pictures
time to fill up a tank from empty is 3mins 15sec, time to top up a tank from cut in to cut out is 1min, i get 25 seconds of free air thru a air duster gun at full 145psi
i changed from PVC 3/8" hose to 1/2" high quality thick but soft air pressure hose
loving life now have a awesome air compressor now i just need a air receiver for more volume for when i sand blast

Glad to see you got it going.
Try some solder on the pin hole.
Before adding a receiver tank try out your sandblasting set up. The tank will give more run time but will require more fill time. Frustrating to say the least.

Here is that little hose pinch fitting that i had to fabricate for the pilot hose fitting made on the lathe i first tried to make one from a mig welding tip but the brass was to soft in the lathe so whizzed it up out of a 6mm bolt
Loth the lathe
The other picture is the delivery hose and pulley

Hi Gazza, Guys,
It looks like the belt has been riding on the bottom of that pulley.
Indicating a worn belt or a worn pulley or both.
As far as the nick in that copper tube is concerned a cooks torch and cored solder. Give it a good rub with a scouring pad first to get it clean. Or Bakers fluid on a cotton bud. Don't let bakers fluid get inside the pipe though.Best Regards:
Baron J.

Have to agree with BaronJ, looks like its rubbing on the bottom of the pulley.
From one of mine you can see the bottom and a small section of the sides are untouched.

The outer of the belt will not always sit this flush with the outer of the pulley but should be no more than a couple of mm inside. Yours does sit a fare way down inside the pulley.

I have got away with machining some out of the bottom of a pulley before. Just a temporary fix until I could find a new pulley.

By the looks of your pulley to mine mine is well worn I'm also assuming if the smaller pulley increased in diameter it would increase the pumps rpm is this right?

Increasing size of small motor pulley will increase pump speed, but will also increase motor load and can cause the motor to stall or cook itself.
Also need to check the recommended rpm for the pump, too fast will cause excessive wear.
The top of the copper tube looks like it has been twisted and will have weakened it, I woul get it replaced, simple job with a plumbers flaring tool.
What is you intent with regard to blasting? Blasting requires lots of air, and I mean lots. You may be disappointed if you intentions are much above small parts.

The pulley looks like it's ~3mm into the V.
For a 100 mm diameter pulley that's about 6% smaller so the rpms will be 6% higher, for a 1440 rpm motor that is about 86 more RPM, probably not going to make a lot of difference to the compressor but its still worth fixing for other reasons discussed.
