I haven’t used a machine shop in 40 years but from what I hear like every thing else they are a fortune 

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.

Sure pay to know somebody in the machine shop business I was thinking the same thing …. Bob

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

Bushing are no problem internet search show all sizes with reamers included.

 Trick is being careful on the set up so you keep the shaft centered where it was to begin with. 

 Get the alignment wrong and the throttles will not close properly, or the ports will be in the wrong area to function properly.

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.

Thank you Larry 

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.

Some old carbs wear around the throttle plate rod that goes through the base plate. Makes vacuum leaks there's no fixing 

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.

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.

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.

Bob, I buy my Motorola Droids for $150 from Amazon.  I don't buy through Verizon, that is a ripoff.  Same phone, 2023 version that they want $700+ over 2 yr contract.

The more crap they put in these phones, the slower they are no matter what "G" they have.

I know Verizon has flip phones now because friend has one.  He can't use anything else.  He was trying to use an old analog version until they finally sent him a new phone.  I can text him information but he won't reply.

My newest android kinda sucks.  My older ones were better but maybe because it doesn't have all this crap to make it worse? Ya, autocorrect sucks!!!  I'm fighting to just type this and have to say what I typed.

I enjoy tinkering with my Cub cadets.  Early 70s models.

I want to build a loader for the 127 someday.

Actually the wagon has a alum cell my friend made for it, I installed an aftermarket sending unit for a Ford gauge so it reads properly in the stock dash.  Since the cell is under the car I can't just see in the top, it also fills from the stock filler cap on the side of the car.  If the cell was in the back of the car, I would have to have a panel made to divide it from the passenger compartment for fire safety.  I didn't want to deal with that.  The cell is narrow to clear the wheelie bars.

Only heard of people having issues, but never dealt with it myself. Lucky??  

Yup, didn't think about the voltage regulator that typical cars have on the back of the dash.  It could be dead and cause lack of reading.  I suppose checking for voltage on lead to sending unit would be a good start.  I think it is like 9v?

Nothing to the regulator.  Spring loaded diaphragm against a needle/seat.  The nut on the top is jam nut, loosen and turn Allen wrench CW to increase pressure, CCW to lower pressure.  Don't have to remove it unless you want to.  Depends if you can reach it on the engine?  I've learned to dread leaning over fenders anymore.  Tilt hoods RULE!

I was going to get wagon loaded in trailer yesterday but it was 38* at lunch and barely mid 40s in afternoon.  Too freaking cold to work outside.  Likely take Friday off since it will be near 70s.  Suppose to go to test n tune with Buddy on Saturday.  First time his car will be out in a couple years.
