Here's a better picture of the front axle and the power steering fluid reservoir. This one's been converted to power steering.

That's pretty much what I figured. This truck has got plenty of logged hauls that were left in the glove box dated 1998-2001.

I went ahead and took some pictures of the engine for you guys today. I know casting numbers don't say a lot, but there were no engine identification tags on this engine. I was looking for tags behind the injection pump but the block is bare. Can't find any stamping marks like you would expect with a serial number. The E6 in our R model has tags and is very similar other than not having an air inter cooler, what I think is the block casting number was one letter off I think. All the photos I am posting are of the B61 and not the R. My pictures aren't great but they're better than nothing. On another note, what are you fellows referencing asking about 34s and 38's? Wheel Diameter? As for the front axle, I'll take some pictures tomorrow and post them up for you to get a better look at. Thanks! - Colton

Hi y'all, I just picked up an old B61 dump truck. I've been searching for a dump for awhile now and have been waiting for the right one to come up. My Dad and Grandpa ran a R model 300/ 10 speed for along time when I was a kid well into my teens as part of their heavy equipment company. We've still got it but it's been down for the last 5 years or so. I always loved the old bulldog, so I knew what brand I wanted. I usually have a tendency to like messing with older machines, old motorcycles, and old cars. It's kind of my thing and what I'm know by my friends for. As recently as last week my Dad was going through the local and surrounding area on Facebook marketplace looking for trucks and came across an ad for a 1960 Mack B61. He showed me the pictures and I was sold. We went down to Imperial, Mo near St. Louis to look the truck over. It hadn't been started in quite some time and we had fully expected having to do some work on the truck in order to get it running. We pulled in the drive where the truck and to our amazement the owner already had it running! It's got a Mack 300 engine, I think its an EM6, with the Quadruplex 20 Speed trans, and 4.66 rear end gear. Ended up getting what I think is a real good deal on a running driving truck. I'm pretty darn excited to learn how to drive this thing. I've been around heavy equipment my whole life, but this is my first truck, and at 23 I'd like to think I'm lively enough to keep up with shifting that 20 Speed. Any of you vets got any tips for a young guy in an old mack? Particularly on shifting when loaded vs unloaded. I've also figured out why some of you guys carry pry bars in the cab. I've had the shifter hang up in my 56 Chevy before getting stuck in between shift gates, so when the compound lever got jammed up from not squaring off the shift pattern I knew what to look for. Climbed under the truck and got her back in neutral. I've only had it home for a couple of days, but I'll throw some pictures up for you all to enjoy. Bringing it home on the lowboy through St. Louis

I just bought that orange B Model dump that's shown on page 4! She's a runner, 300 with a Quadruplex!!
