Husky VT6299 bogs down @75PSI

by Eddie G
(Houston, Tx)

I have a Husky 30 gal model VT6299 compressor. I let it set up for a time and the check valve froze up. Well I stripped the unit and replaced everything (all new Stuff)

Ran a dedicated line for power.

When I run the compressor it bogs down @75 PSI. I can turn it off before it reaches 75 psi and the unloader will spew.

What am I missing?

I am looking for my ground rod outside the power box to check the ground, my pancake runs just fine.

That it's a 2HP...
by: Doug in your problem, I think.

AFAICT, you need a 5HP.

Change the the motor pulley to half or a bit less than its present size and it'll probably go on up to cut off, assuming the rpms are the same

New pump. "all new"

What's old/original, then?

Is it the original motor? What's the rating on it? Running it 120 or 240v?

How 'bout the pulley and sheave/flywheel?

So, you have replaced the pump with a new one?

I know you replaced it, but do pull the tank check valve to ensure that it's not binding at all. Not likely the issue, but one that needs double checking.

If the check valve is good, as Doug suggests, next check would be the viability of the start cap.

Power good, had electrician run a dedicated line and check voltage, Pump is brand new from Campbell Hausfeld.

I'm pretty sure that's the pump, as opposed to the unit, so the model of the unit assembly might be useful.

Anyway, is the power good? Could be any of wrong voltage, too small wire, or bad connection somewhere, causing voltage drop.

After that's verified, I'd be checking the caps on the motor.
