Rebuilding my Triplex

[Freightrain]

I'll work on PT 3 tonight.  Not sure it will get uploaded until tomorrow night.  It takes like 2-3 hrs to edit and save and 2-3 to download.

[Freightrain]

Ok, the third and final video is uploaded.

haha thats quite a run down,thanks for that,,,all your gears look new,,bob

[Freightrain]

Well, it is back in the truck.  Nothing hooked up, but it's in there.  I will get on it tonight and start the long process of getting everything back off the floor!

You'll have to learn to shift all over again, if it is anything like when I did my cabover. Everything tightened up and changed the arm movements needed.

i had not thought about that,,,reminds me of the first time i drove a 13 speed road ranger was used to a 10 speed,,,,and i was only 20 lol.....grind grind grind,,,took a while

I still need shift towers.  Now that I have them mounted, there is still plenty of slop in the handles.  Nothing much I can do for them, I have been into them years back.  Pins are worn, shift ball is worn.  But that is for another day.

Empty spot in garage 

 

I forgot to get the frame mounts cleaned and painted, so that is next but have driveshaft in, shifters on and a few other misc things attached.  Once underside is done then I will get fuel and air tank back on so I can set truck back on the ground.

Same Rustoleum gold I used on engine but this stuff sucks big time.  No gloss, scratches off really easily.  Oh well, nothing a bit of motor slobber won't cover 😟

[seyser]

That looks really good! Nice and clean.

[mowerman]

not much you can do with rattle cans,,,,its usually just quick and easy,,,,nice neat work,,,,

[mowerman]

and everybodys garage looks like that after a big job,,,,i can cludder up mine just pulling apart a lawnmower,,,bob

Can you put a oversized pin, and weld on the shift ball and round it down and smooth it, i have done that in the past. Terry. 

[Freightrain]

I think that is what I did before, I know I had to weld the pins in.

I found a shifter on eBay, has Mack pt no. but not sure what it fits.  Looks like correct mounting.

Anything made by man can be rebuilt or remade by man esp if he has access to a machine shop to do so! 

I'm betting you'll come up with a viable solution.

I finally had a chance to watch the video's 

I have been a tad busy of late

Fantastic job on the rebuild, great stuff all round and hopefully it will give many trouble free yeara of operation 

The oil pump plunger should sit in a eccentric or out of round doo hickie and pumps in and out as the shaft rotates 

On my 12 speed someone had sealed it up with aome RTV silicone sealant crap that oozed out on the inside and broke off, then this crap got pumped through the oil galleries and eventually got stuck on the sliding dogs 

Required a complete disassembly to fix 

And I think my box was dirtier than yours, what a mess

Great work and a really impressive job you've done

I looked at the shifter that was on my 5 spd that came with the 300+.  It is the same mount.  I think I can just purchase new ones and cut the handles off and reuse mine.

Rebuilding them is a moot point.  The sheet metal pocket the ball sits in is worn, the ball is worn, the pin is worn.  Too much crap to deal with for what it is, if I can make others work.

Well, last night I buttoned up everything, including getting the floor back in.

I found a leak in the transmission, seems one of the side bolts I left out in the rear box must be a through hole as it seeped fluid when I had the truck running the other night so I siliconed the bolts in and need to wait for that to set up before running it again.

I also did a whoops the other night.  I installed the air start tank before moving the fuel tank so it is stuck behind the truck and no room to wiggle it through with the air tank in the way.  I put the tank up on the rear chassis and once I pull truck out I will install the tank.  Luckily it runs off the driver's tank.

 

I should be able to test drive it tonight?  Weather is good, roads relatively clear.  We will see.

[Freightrain]

It's mobile again ....

 

Needs a really good bath, but it runs fine.  Shifting was a bit tough at first, then it warmed up and shifts better.  It was always a bit snug when first out but the compound was really stiff.  Seems much better after 1/2 hr of driving.  It's quiet and handles don't wander around anymore.  My Jake switch is outta whack since I had removed the clutch pedal.  I need to get under there and line it back up.  It will work once, then not again.  Simple fix.

[mrsmackpaul]

A great result, all these older types when in good order are pretty stiff and shifting has to be slowed down until the oil warms up a bit

I think them three holes on the side were for handbrake bracket.  terry

Sounds plausible.  Can't believe one of them was a through hole?  Kinda dumb.  Though the two holes for the "filter cover"(that oil trough/magnet) are through on the passenger side.  I'm not sure I used any RTV on the threads?  One is just damp but not a serious issue.  I may just clean that area and apply a dab of RTV on the surface(threads just below the surface) and hope for the best.

Hats off Larry that wasn’t incredible how fast you got that done 

[Freightrain]

Thanks.  I just kept picking away at it.

Imagine if I had a clue what I was doing???

[mowerman]

[Freightrain]

Car transmissions are easy.  You can carry them around.... 😆.  I can do a Ford Toploader in my sleep.

Yes, even rattle cans throw a lot of spray I like the blue myself but I’m also a Ford man ha ha just put it back in and run the piss out of it let us know how she does …. Bob

Awesome job Larry! Looks great. And as far as the spray paint goes,..

had to go out and get Roman and Belle. 2 kids were walking by so I had to grab Roman before he decided to bite their shoes. 

Anyway, where was I- oh, spray paint. I got a little agitated in the Walmart store a while back when I went to pick up a can of appliance white paint. Not to paint an appliance, but that's what we used to paint our wheels with back in the day. And all the spray paint was locked up, you couldn't touch a can of any of it. There was a button there on the wall and a sign that said "Push For Help". So I pushed the button to summon help several times, waited around about 10 minutes because I wanted the paint, but no help ever arrived. So needless to say I got pissed, threw all my other items down on a counter that nobody was at anyway, and left. I went to the hardware store and got the paint, probably paid twice as much for it, but oh well.

Somebody told me me later that it was locked up because kids were "huffing" it to get high. But when I went back to the Walmart store I actually saw somebody who worked there and told him the story, and he said they locked it up because people couldn't just go by the color on the cap, they had to spray in on something. He said they would ruin $600 worth of merchandise spraying a $6 can of paint to test the color.
