Craftsman 919-152251 - Question on a ABP-446 Pump

by Neil Cunningham
(Hickory NC)

I have a new to me Craftsman 919-152251 Air Compressor.

The pump is leaking between the head and the air outlet.

I have ordered the gasket and just wondered if i need to use any sealant on it or just put it on and snug it down?

Does anybody have any info on this pump; torque settings?

Also does anyone know the high pressure this pump can do? I was under the impression that 2 stage pumps would be in the 175 PSI and this unit is not set that high?

Just curious?

May 3 poster: 175 psi

May 2 poster: same or similar to the head gasket, if you can tell what it is. See ICS post below.

919.175251 with ABP-446 Pump torque spec
by: Doug in

Couldn't find a spec for the 446, but the replacement 4900 pump is virtually identical.

All the bolts into or through that head are 18.1 ft/lb, so I'd go with that for your part.

Good luck.

ABP-446 gaskets
by: ICS

Depends on the material the gaskets are made of. If they are graphite gaskets, no sealer should be needed. If it is paper, and all surfaces are clean and smooth, no sealer will be needed, however, I always like to use a thin coat of sealer on any paper type gaskets as the next time you remove them it will be a lot easier.

Pressure is limited by the motor, probably.

But I'm not finding 919.152251 - confirm model?

And there's probably a torque spec for the head.
