You get what you pay for like most instances. My work place specializes in Injection molding. The shop that does my motor work is a bit on the higher side, but that is more for the fact they won't cut corners, at all. Do it their way or take it some place else. They will tell you so. With the large drop in shops like it, they can be picky. They are swamped as is, so a lost job isn't hurting them. I have been using them for 35 yrs.

No doubt. Worked in machine shop for 38 yrs. Handy thing to learn.

That's where havng a few reams and test fit and find one and use it for setting centerline. Definitely need to adjust throttle blades when putting it back together so everything closes perfectly. Tom did shoot around the base and didn't note any changes in RPM. I'm still hoping for something plugged in the carb. Time will tell.

301SQ46B was the part number I used.

She has helped me once before so I knew she is capable. An older gentleman came up and assisted her in finding the part numbers. She kinda knew what to do but I am likely a rare bird coming for parts on a 60s VIN. The original parts guy, Jeff, retired. He always remembered me though I only came in about once a year. Another fellow, my age?, is still there and remembers me.

A mill and a ream will fix worn throttle shaft. Press new bushing in, presto, good as new. Changing to different carb would only be an issue of bolt pattern/bore size was odd? Not sure how interchangeable that stuff is back then? Let me know if you want me to help Tom. I can even do the throttle shafts for you.

My local Mack dealer parts counter has gone downhill. Poor girl(she admitted to not know big trucks) couldn't find exh gaskets and fold over locks for a 237. Older gentleman had to help. She was trying but my old VIN didn't help in new system. Told her 2 valve head and she said "I don't know what that is". I didn't critize her, I was very understanding of her situation. Fold over locks NLA, gaskets were $24 ea. Found everything on eBay. 6 Locks $17, 6 gaskets $55.

I think my FA517 axle has that pin. I have to dig out receipt and see what the part number was. I did the pins 22 yrs ago. I have all the paperwork in a folder.

When I hung new doors on my truck I put a sheet of Dynamat on them. Wow...no more tinny ring when shutting the doors. Just a nice thump. I did the floor and the firewall when installing the 237. The short stacks bring more noise in the cab. I have thoughts of making extensions to install once out of the garage to quiet it down inside(and keep soot off the trailer). I don't want to see a band clamp on the stack but I really need to look into it.

After I bought this in 1988, it hasn't seen water but from a hose. If it was cloudy, it stayed home. It's far from perfect these days, but still my original pride and joy. I want to do a full restoration but in today's world that likely won't happen now.

Great first outing. You get used to the "they know me" syndrome. With my near 30 yrs racing the wagon.....everyone knows me.

Over 20 yrs and lots of miles with no issues.

I put a separator filter on the frame next to drivers tank. Easier to spin that on then deal with engine mounted canister. I still have engine canister but don't change it as often.

Same red one that is in the original picture from Paul? That is the one I have seen a few times.

285/300 hp Mack motors are bulletproof as is the 5 spd. Mack will pull down to 1100 rpm, so it drives differently then other big diesels, thus the 5 spd. Kinda slow driving and shifting, but reliable.
