Cats Forever
Speaking of the D315 engines, I can notice a lot of difference in the horsepower and sound of my 112 3U (1949) and my D4-7U (1950) particularly the RPM's. 112 much higher pitch.
Thanks OM.
Old Magnet, footnote # 12, I assume* must be the break between 955C and 955E at 12A5793? that's good to know the rack setting are different. Thank you.
*yes I know...

1st-1.34 2nd-1.85 3rd-2.72 ?? is 5th 5.37? is there no 4th? i guess there is another lever that makes reverse Hi/Lo?
Phildirt put the shift pattern just above where he wrote "I mostly see...." There's only one shifter, and instead of a fifth gear, it has LR and HR

"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."
