Hydraulic testing

Hey fellow mechanics what is your go to hydraulic testing equipment for diagnostic of any sort of issues I found some on Amazon but that’s some small lines compared to what our units have lol.

But in the mean time can you help me on an issue we have a combo vac truck with a blower actuation issue. It’s on a 2020 kenworh T800 the set up is a west tech vac not for hydravacing. Anyways the issue is it takes forever for the blower to get working specially when it is cold out. Today it took the blower 30mins to kick in. We had switched out the control valve off the side of the Dan foss pump but didn’t do anything. As we were told it has little orifices that could be preventing oil to get through. So would the issue be in the drive motor for the blower or possibly the relief valve which is the lever operator this Brannon hydraulics company is calling it. We use MV22 Hydraulic oil!

 

It’s MV22 we use it in everything all of our vac trucks use it. Even in the shop over night it will take a bit to fire up also. Which it shouldn’t

 

It was -42 with windchill in high level here!

oh perfect maybe you’d know the issue. Ha we’ve always had custom vacs never really an issue for blower wise, but this west tech is a different breed. We use MV22 oil. Sorry I just edit my post to add that. It has a manual 18spd. PTO has been rebuilt! Pretty sure pump is fine cause all the other Hyd side of things work Hoist, pressure washer, roper, but the PTO does sometimes stick in and won’t disengage for a bit.

I’ve never posted pics before but will try I will maybe look into those companies all we have local here is a Gregg’s. I found some kits on Amazon may give it a try!

 

No id have to contact westech on that I’ve tried getting one before but there not the best to deal with unfortunately! As they want to send their mechanic 10hrs north to work on this. And also told me it’s the blower which I highly doubt cause when the blower kicks in it’s the best vac we have.

 

Here’s a few pics il get few more

 

This is the actuator that activates the blower….. not sure what valve u refer to.. the pump is a Danfoss. All I know is dont have that email from way back when we bought the compensator valve from west tech. With the model and all. The motor is a Roxroth

Relief pressure settings are manually controlled with the lever operator. Mounting flanges and a lever position lock are also include
