Hi everyone. Someone asked on a FB page what the horsepower was from a pony motor on a D6 9U?
Dummy me, I had to be the first one to respond and (blame it on age) blurt our that it was 29 HP ?
Which everyone politely said ain’t no way...
So, what’s the correct HP? Any other specifications as to displacement, torque and operating RPM range?
I need to be schooled on this, as I’m still learning too!
Thanks everyone, JM

The biggest pony motor that cat produced was on the D 17000 that I know of.
And that was around 27 hp .correct me if that is incorrect OM.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
