Chev CMP PTO design and use

[Adam Godwin]

Hello Gentlemen!

I’m Adam, from Australia, and I’ve been reading the forums for quite some time now.

I am thoroughly committed to buying a Chev C60L, when I’m fortunate enough to find one.

I have questions about the PTOs on these vehicles, and hope I’ll find some advice from you clever chaps.

I used to have a ‘73 F350, with a PTO driving a hydraulic pump.
It ran a loader crane, and although useful, it was quite noisy.

I’d like to use the PTO on the CMP to power a hydraulic pump, to run a small crane, water pump, compressor and generator.

What is the the range of operating revs for the PTO’s on CMPs?

Are the PTO gearboxes of straight cut or helical gearing?

What sort of horsepower can be transmitted through the PTO?

Are these PTO gearboxes suited to intermittent use, or continuous duty?

Are these noisy units, or can they be tweaked for quiet operation?

It’s possible that I’d use the compressor, pump or generator, for stints of half an hour.
Is this too much of a demand on these PTO gearbox units?

Looking most forward to any advice!

Thanks very much, fellas.
