Help me?....

I usually use a length of cord or small diameter rope.
Make a mark on the rope, white nylon is nice, run the rope around all the pulleys bringing it back to the pulley where the mark is, make another mark in line with the first mark, then, using a tape measure, measuer the distance, mark to mark.
That should get a mighty close to what You need for length.
But then, I do believe that the multigroove belts is measured in metrics.
You will need a metric tape measure or else convert inches to metrics, a computer and a search engine really helps in such matters as that.
I dont know if You ever got a introduction thread but, welcome to thetruckstop.

Thanks really appreciate it. First diesel. It's got a dump bed on it didn't come with air and vacuum pump isn't even hooked to any vacuum lines anywhere. Lol

Does it have a turbo master attached to the side of the turbo charger ?
It will be a spring loaded affair hooked to the lever that hangs on a shaft out the side of the turbo.
If it is just the vacuum actuator without a vacuum hose then need to determine if the vacuum pump is actually functioning. A vacuum gauge will tell how many inches of vacuum it is pulling. If it is pulling less than about 25” of vacuum then a new pump should be installed. I may be wrong on that number so wait until someone with more know posts in.
A turbo master can be purchased or built and installed, a boost pressure gauge will be required to determine that it is not over boosting if using a TM to control boost.
If this has a belt driven hydraulic pump then there will be no standard belt fitment that could get the proper unit. Every manufacturer had their own system of attaching the hydraulic pumps and they would vary.
So then it comes down to, if You want to run the vacuum turbo control system or the TM and remove the vacuum pump, that will have a factor in what length of belt You will need.
If there is no control device hooked to the turbo, the fuel mileage will greatly suffer and it will pour out black smoke, that will contaminate the engine oil and excessively wear on the engines bearings.
Not a good scenario.
 
Welcome to the forum! are you deleting the vacuum pump or has someone already done that and you need to find the correct belt?

I looked up by application and it shows a 1010k6 with ac (100.9") and 1020k6 without ac (102") iirc you just go 1 inch shorter to eliminate the vacuum pump, but I have also heard that without the pulley there, the belt will flap around across that long stretch where the pulley was.

Then add on if the hydraulic pump is belt driven with an A/C type clutch drive.
 
My advise would be get every belt that may work and return the ones that don't. Unless someone here has the same year truck and did the same thing no one knows. Speaking for myself.

I put an hydraulic pump on my engine, it went from 101"? to 108.5? It was trial and error. :)
