MorrisMe Posted January 1, 2023 Author Share Posted January 1, 2023 engine turns over but the starter is not engaging, so I get to start there with this one. Found a bunch of new / rebuilt / spare parts for this under the seat, great treasure hunt lol. Also discovered that the Mack Dogs for the sides of the hood are much larger that the standard B model Mack dogs? I found a new old stock set of hood "Dogs" for a model B, but they are way to small to fit the hood. Does anyone know where I can find the correct emblems? Are they specific to the B-21 or did they come on other trucks as well? I would guess that they are about 2" bigger then the ones I received.

Mark T Posted January 3, 2023 Share Posted January 3, 2023 I've only seen one of those in real life. It wasn't running and I doubt it would when I saw it. They were something.

It is an amazing truck, the second one is looking good on the path to being a runner, I changed the oil and filters today, (All looked good for sitting so long) and added a mechanical oil gauge in the engine bay, cleaned up the points and fixed some wiring connectors on the coils, cleaned up the starter (bendix was stuck) now it's rolling over nice and smooth. Ran a bore scope to check the cylinders out, everything is looking real nice. Tomorrow new plugs and carb clean up, I will try and post how it goes. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/70785-b-21-fire-truck/page/3/#findComment-519798 Share on other sites More sharing options...

MorrisMe Posted January 6, 2023 Author Share Posted January 6, 2023 Well number two is also up and running, although after about two minutes of running I blew a oil line. My son did take a "startup video" of it and when he gets it finished I will post it. Ran beautiful and smooth once it got fuel. Anyone know which Dog emblem I need to buy to fit the hood? I purchased some B-Model dog emblems for the hood but they are too small and angled up, the hood outline of the Dogs are standing flat and about 2" bigger. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/70785-b-21-fire-truck/page/3/#findComment-520154 Share on other sites More sharing options...
Popular Post mattb73lt Posted January 6, 2023 Popular Post Share Posted January 6, 2023 This is the style it should have, level, flat and rounded. If it is more angular with sharper features and has a more upright stance like the radiator mascot, then it's probably for an R Model or later. 3 Quote Link to comment https://www.bigmacktrucks.com/topic/70785-b-21-fire-truck/page/3/#findComment-520155 Share on other sites More sharing options...

Draggin Wagon Posted January 7, 2023 Share Posted January 7, 2023 Wonder why they have a u-joint half way down steering column? Guess steering box is mounted further forward than B20 thru B60s?

mattb73lt Posted January 8, 2023 Share Posted January 8, 2023 I never realized that they did both the fender extensions and the extended radiator shell to fit that huge Hall-Scott in there. I always thought it was just the radiator shell, but I've never seen one in person or close ups pics of one. Kind've like using B73/75 and B71 parts to fit it in there. I know a Cummins is 6" longer than a Mack engine, so maybe the Hall-Scott is about 12" longer? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70785-b-21-fire-truck/page/3/#findComment-520346 Share on other sites More sharing options...
Mark T Posted January 8, 2023 Share Posted January 8, 2023 Hall Scott is pretty big (one of that model anyway) I've only ever saw one in real life. It was big , sorta like big bore Cat in some respects. An impressive looking engine somewhat like it was ahead of it's time or something. I bet as far as length , an E7 would fit where the Hall Scott would. .
