75 (flywheel) hp @ 2000 rpm for power shift, and 75 hp for direct drive @ 1900 rpm for D330 engine.

Got it, thanks
Everything I have says 65 hp on the D330. Changes to 75 hp on the 3304 and I suspect with the D330c also. What specific model and s/n?
78A 5716 direct drive

I’d like to know what horsepower my 84J is as well; 22xx serial number? Turbo with LOTS of power. Thanks.![]()
The entire 78A series is 65 hp D330a.
The 84J 1525-up is a 78P series 3304 engine at 75 flywheel hp.

OM, My information came from Caterpillar Track-Type Tractors D4D/D5/D6C catalog/brochure FORM AEO21118, not sure of year. Early 1970's maybe?
Specs page says D330, However it does state on page 7, We've increased the hp of all three tractors (D4D) 75 flywheel up from 65. Would that possibly mean the D330c engine?

Sounds like it, it was in 1972 that the D330c 4-3/4" bore change occurred.
Ok, Thanks.
