Good morning all.
Well, i have been wrenching on that Crawler for a week now, was able to figure out the puzzle that is the Shawnee loader assy… first thought was to rig it & pull it off whole, nope!
Arms come off, then fender towers have to be tilted just rite so as to come out from under the tracks. At first thought i was going to have to split them, Grrrr! Gotter done. Boy has she had some hard use & not much love or grease!
Drained engine oil, (2) 1/8” pieces of non metalic, non magnetic something? & (1) sliver of metal, & about a quart of h20 & alot of sludge! Tore oil filter apart, nothing in the pleats. Engine does roll over, so thats a plus. Going to drop the pan, when it stops raining… then radiator etc to get ready for extraction! Just thought i would share, i know im weird, but man do i love this stuff!!!
Have a great day!
Any comments & or suggestions are always welcome.
Shanon.

Ok, will do tootsd1, thanks for the tip. Im in north Idaho by the way, i like to call it my paradise!
Udate on the 56 420 5 roller 4spd.
Pressure washed!
It is now in its own custom built Crawler shed.
Ready for more trouble shooting.
Next is pull & check, plugs, valve/rocker box,
& oil pan.
Along with a million other projects….
Go easy my friends.

Hello from the great state of Idaho!
Pulled the valve cover/ rocker box, looks good, clean, oily, springs, push rods, look good, when turning fan blade they go up & down. Pulled plugs, forward jug, sooty, but all there, rear jug, wet, oily, but all there.
Next is drop pan & inspect, will have boss lady turn fan so as to be able to hopefully see or hear any issues.
Lavoy, if it did indeed spin a bearing, is there a possibility that i might be able to feel or see any play?
Or will it require a tear down to find out?
Something else i found that im not sure i mentioned is the exhaust stack was completely closed off tite with a piece of steel that i had to ram a form stake against a bunch of times to beak it free, that probly didnt help! Yikes!
More to come, have a great day!

If you can fel play, they are really shot.

Ok thanks Lavoy, fingers crossed!
I did find that the exhaust/intake manifold is cracked in the back side of the Y, just like my 58 was.
So, with the exhaust pipe completely blocked, & manifold cracked, it probly sounded like it blew up!
But hope it did not. We will see…

Good morning all.
I have a quick question to whom ever would like to reply.
Where the frame bolts to the final drives, the frame is counter sunk/concave to fit the 1” convex nut.
They have all come loose, & at first looked to be wallered out, but are not after further inspection with readers & a good light!
They are grade 5 & look to be fine thread,
Getting to the point.
Should the fix be, #1, red locktite & rattle gun?
But can the grade 5 & fine thread handle that torque?
#2, get grade 8 fine thread bolts, & locktite? Or,
#3 get grade 8 coarse thread bolts & nylock nuts & locktite?
Dont want them to ever come loose again!
Thanks in advance for your input & help, it is greatly appreciated.

[theshanmand1!]

Well, according to my cheat sheet.
Grade 5 @ 7/16” bolt can take 54 ft lbs.
So, they are going to get a thorough cleaning, a good dose of red locktite & 60 ft lbs.
If that doesnt feel like enuff, i will go to the next level that is 78 ft lbs.
Ok then.

Do NOT replace the acorn style nut with standard nut, it will not work, stuff will start moving around. If the original studs are intact, replace the nuts, torque to factory spec, and just check the periodically.
