MK5 Crankshaft Pulley for two belts

[Peterr]

Crankshaft Pulley for two belts, “V” and “Grooved” for AC

[MinorMatt]

Thats not an AC pulley - its a non AC one. The power steering is driven off the front Vee.

Aircon ones have 2 plates for multi vee belts - the AC belt is a 6pk one

The AC compressor doesn’t have a V belt

I believe there are two versions.

This uses two V belts

My MK5 looks like this and I want to mount the compressor. I have the proper bracket. Just need to figure out how to add the belt. I intend to use the compressor to fill a rear mounted air tank to about 8 bar for painting. This has been done before with the same compressor and works great.

Yes you can see the 6PK belt drive on those. No V belts

This uses two V belts

Thats an aftermarket PTO rather than aircon. Common for ice cream vans with soft serve. There is a shaft that come out and drives the machine in the cab

[Peterr]

PTO means? 6PK means?

[MinorMatt]

PTO is power take off - typically engine driven with an electric clutch to drive a shaft or hydraulic pump.

6pk means a poly Vee belt (the flat type with lots of grooves) - with 6 grooves. The other one is a 4PK - 4 grooves

Thanks! I need to figure out how to attach the compressor and add the correct pulley. I already have power steering. The options are to change the crankshaft pulley (only V belts) or change the compressor pulley (which currently has a 6 grooved belt) to a V belt which may be the easiest option.

[MinorMatt]

Im sure I will have a crankshaft pully with the inner 4 groove belt and the single V on the outside.

I got rid of the ones with the 6 groove when I sold all my aircon stuff

[Peterr]

The compressor has 6 grooves. Don’t know if it can run with a 4 groove belt. Wouldn’t be critical since the compressor is only occasionally running. (Photo is of another engine where I removed the compressor)

[MinorMatt]

Ok,

So you need the type with the 4 groove belt (alternator, water pump etc) and a 6 groove for the AC Compressor... (not the type shown in your pic).

It appears you are looking for part no 1042771 or 1050620

I've looked and I can't find one at any of my normal sources
