300+ rebuild

[Freightrain]

Yes, I lost a whole weeks worth of time to get it done and that is a lot of time!!

I stopped at hydraulic store today(not Parker) and started on power steering lines.  Had to order a fitting for suction side (5days Ugh).  I had them make one line, I have to measure up for the other two lines.

Getting close, but still so far to go.

Success!!

I did make a dump truck clutch!!  Two fingers is all it takes to depress the pedal.

It is far from complete but it does function.  Few more things to machine but a HUGE milestone.

I got the floor reinforcement brace across the floor bolted in so I can now cut the removable panel for the new shifter and get the floor installed.

I'm taking Friday off so I can get the last two power steering hoses made and installed and it gives me another full day to work on it.

Yeah, that collects linkage is definitely dynamite. Fantastic work Larry hats off bob

I was also thinking right now it must be right. Frustrating to have to keep going to work in the middle of this ha ha… bob

Ya, I spend all day at work trying to figure out what I can get down that evening.  One week to go.  I need to be able to swap cars around and be ready in 9 days.

 

Tick tock.....

IT MOVES!!!!!

I installed the new pump(another story) and got it running.  I was able to air it up, release the brakes and was able to push the clutch and easily slip it in gear and slowing inch the truck forward(can't go far).  I pushed back down on the clutch and slipped in reverse and backed it up.  Nice!!!!

I released in neutral a few times and pushed down fully and was able to slip it in gear without any clash.  I did it numerous times in forward and reverse.

I then pulled the linkage all off, drilled the pivot bar for a cotter pin to capture the Z bar.  I installed the grease zerk in the bar and put a couple clicks of grease in it and spun it around a few times to work the grease into the bushing.  I then bolted it in for the last time and attached the clutch rod to the transmission.

Now I need to recut the keyway in the pedal pivot rod and finish the machine work.  Install pinch bolt detail and then split the ring.  I need to install the bracket for the return spring.  I am pretty sure I can modify the original bracket and weld it to my new arm to enable the stock spring to be used.

 

Not onto the new pump.  Ugh.  I installed it and the given primer pump didn't work(ya, I knew that was coming).  I installed the old bailing ring pump from my 237.  It still had issues getting fuel up.  I still have the pressure gauge installed in the fuel filter housing to watch.  I finally got it primed and engine as started.  The 20# I pumped up slowly dropped off like before.  I pumped it while running and it went back up to 20#.  Then slowly dropped again.

I removed the return check valve assembly and investigated it.  Nothing wrong I could see.  Sealing surfaces were fine.

I thought maybe I could shim it up.  I had some .010 shim stock and cut a piece and put it back together.  I could pump 30# now.  After starting it would again just slowly drop off.  Less of you didn't rev the engine.  It would idle for as long as you wanted.  I did finally get some heat in the engine and topped off the radiator.

Tomorrow, after getting the other power steering lines made I am going to make a short fuel line and run it off a can and see if it keeps pressure.  If not I am not really sure what to do next.

I tested the Jakes, they work.

After I get the clutch parts in for good, I can put the floorboard back in so I can tidy up the interior and keep moving forward on the front end.
