How can I tell if my turbo is working on the Mack B75, ENDT673?

OK, thanks gentlemen. I'm about maxed out at 55 and 2000 rpms. Can't keep up with the big boys but I catch them in the mountains. Single od, quadraplex. Emd 673 turbo.

Found r 6.34 on real bogie; does this mean the ratio is 6.34?

Thank you j, this was helpful. I found the numbers are depicted in the tech sheet but it doesn't tell me much. The carrier says CRDP 92.161.66, what does this mean? ron

Kind of hard to do with two rear axles. I'll chk for the stamp.

How can I determine the rear axle ratio for my B75? ron

10/4, thank you, I'll check it out.

Adding spring brakes to my old trailer. Have service brakes only now, what components do I need? Have relay valve on truck (B75 Mack) for truck spring brake: do I need another relay valve on trailer, or what? Simple diagram for a simple man, please.

Trailers do not require insurance in California. Insure the truck with JC Taylor and don't say anything about pulling a trailer.

15 bolt. Need water manifolds also. ron

Looking for heads for '26 AB Mack. Some low-life crack-head stole parts off my truck, anyone have any leads? Thank you. ron

ATHS is not as inclusive or interesting as ATCA. ATHS does not permit any truck on it's cover that is not "restored". Many beautiful antique trucks are out there but the bloated ATHS does not recognize them but they do constantly beg for money for their headquarters. Most issues of the publication are devoted to modern trucks and as such has no interest to me. JMO. ron

I thought only the AC Mack was caled a "Bulldog"; is evry Mack a buldog?

Thank you, Sir, I'll give tem a call. Shipping may be too much for me.
