300+ rebuild

[mowerman]

Well, I’ve made a lot of mistakes of my time if I could go back and do it all over and pick the right routes  I would be signing up for it now I used to hear older fellows when I was a real young guy saying the same thing. I wish we could start over and know what we know now didn’t quite know if they were talking about now that I’m old. I see what they were talking about. sorry Larry it seems to keep going off rail ha ha ha I know you probably don’t care that’s all interesting conversation.

Paul, I would agree with that!

What we don't know is how long we have left. My Aunt is 99 and sharp as a tack, and still active. My friends father worked 3rd shift until he was forced to retire at 65 and was dead before 66. Genetics has a place in it, but is not the total picture.

Oh, one more thing it usually takes me way longer than I figured to do anything. It doesn’t have to be truck repairs. Also home repairs that’s it ….back to Larry.

i bet watching soap operas has a lot to do with it!!  🤣

True no one knows how long is left.My best friend passed away at just 46 of brain cancer 18 years ago leaving a beautiful wife and 3 great children behind.On his death bed he made me promise Id live life to the full.So if its tomorrow or 20 years time thats what I intend to do......

My excuse for slowing down other than my age is in 2022 a pickup pulled out right in front of me when I was riding my spider motorcycle I was doing about 40 mph. after two weeks in intensive care and two weeks in physical therapy I was able to come home in a wheel chair I had a fractured skull, bleeding on the brain, broken nose, broken jaw, knocked out a good share of my teeth, broken shoulder, broke all my ribs on the left side they stuck them back together with a mesh and screws, punctured lung, broken hip, broken a lower bone in my back I was told when the medics got to me I was more dead than alive I can't lay down I have to sleep setting up

What HE SAID!  I am feeling every trans and drive line and main bolt I have ever torqued  every day! Every joint hurts ! I think it lowers the motivation some what !You Got to just over look iT If you want to get stuff done ! Ignore it and power thru! 4hrs at a real slow pace is about all I can tolerate these days! Count ourselves  lucky were still able to do this stuff! Could be alot worse!

Thanks all for the stories.  

Here is some Saturday updates.

Carrier bearing bracket:

1/2" plate welded to fit.  I don't have any fab shop available since buddy retired and business was bought by new company.

Due to slight misinformation the shop put the bolt pattern on centerline of my bracket, instead of a couple inches behind so I had to zig zag a bit.  No worries, it will work.  Just had to cut and paste it a couple times.  Took a few tries to get it tacked in proper orientation before welding solid.  I can't reach truck with welder, so had to use digital protractor and guesstimate, then tack, reinstall and see how each piece fit.  Couple times and it was dead on.

Now to drill for the four holes to attach to existing cross member.  I have driveshaft angles all worked out using online calculator.  I will need to roll pinion down from 5* to about 1*.  This frame was from a short single axle and the driveshaft was short and aimed up.  Now I have to go 120" and it has too much angle to get there.  When I had the third box in, it wasn't an issue because it had a short driveshaft.  There are a couple shims to pull but not sure if that will get me down.  I may have to cut torque arm and shorten a touch.  Time will tell, that is for another day.

I got the cruise control cable all remade and hooked up.  Should function as well as before.  With the Z bar reverser I had to extend the cable to get to the block side and around to pull.

It used to have a bracket on head of compressor and pulled on pump arm.  This pump works back asswards and so has to reconfigure it.  Luckily a std throttle cable fits it.

Exhaust downpipe:

After picking up the correct clamp, a short piece and a SS 90* pipe I was able to fabricobble it into one piece and it aims right down to my existing pipe that runs down under the truck.  I just need to weld a 1/4" npt bung for my pyrometer.  Will do that at work Monday as I need to use SS and TIG it.  I only have mild steel Mig at home.  Don't zoom in on the welds.  They aren't pretty (my buddy would have made it look like jewelry but I wanted to do it myself).  Thus I put some black paint on it.  Ya, polished SS, it was what they had.

Driveshaft sorta hanging in place.

It will get wiped down after carrier bearing hanger is installed and then put some paint on it.  Damn that thing is HEAVY!  Even in two pieces.  I put it up one piece at a time.

 

I purchased steel Friday for the clutch linkage contraption.

New revised sketch.

It won't criss cross now.  I am using the longer arm from the old Mack 5 spd(fits perfectly) and gets me down and away from transmission better to allow linkage clearance.  It is the larger circle, the smaller is the arm I am building for clutch pedal.  The item to lower right is the Z bar and it lays out the motion and travel I need.  It is a plus to be an "engineer". 😆. I am nothing of the sort, but can draw shit.

I will work on cutting pieces out for some machine work this coming week.

Progress.......baby steps all around.

Excellent… my god that thing fights you all the way …. It must be some how related to my DM … excellent progress  … where did you find the correct exhaust clamp????

Heater hoses look like they need to be moved. too close!  I ran into a "heat problem" with a wiring harness I thought was far enough from the turbo/exh. It was, except when pulling a grade in the summer. Heat shield came to my rescue. I had much more space then you have there. I thought it wouldn't be a problem but I was wrong.

Absolutely.  Once I get the pipe installed I will be working on a heat shield and tying the hoses up.  It wasn't an issue with the 237, but this manifold tilted the turbo outward more and creates clearance issues.

Bob, I got the clamp at Mack dealership.  It was in stock?  Strangely enough.
