PROJECT "Father/Son" C-20 Rolling Chassis Build

[ChiefRocka]

BTW....the Notch is complete.....

-
Back on the rear ends.....
-

-

-
Side by side......

-

-
Preparing to transplant these saddles...making a jig for them....
-

-

-
Also made up this plate for the pinion.....I want this to be accurate
-

[ChiefRocka]

The last few for tonight.....
-

-
I built this jig to hold the pads at correct spacing.....I will place the degree finder on the tubing, and record the measurement. So I can set it up when I transfer the whole thing to the 14-bolt.
-

-

-
I might weld a 'jigger' to the track bar mount, and transfer at the same time...but then again I might not....
-
-
-
-
See ya....

[ChiefRocka]

I am back with a few more pics....The 14bolt has found it's new home. My jig for the pads worked absolutley perfect....check it out...



Prepped the pads...

-
Setup the 14bolt...(I think this axle might of been in a farm truck, not sure)

When Rich brought this frame over, he also brought over a replacement R/S trailing arm...because he thought there might be a problem with it. (the axle was loose, possible cracked arm). Well, it turns out the u-bolt, overtime, had loosened and rusted in place.

So the OG trailing is fine. In fact, there was a huge weight difference from the OG C-20 arm and the replacement C-10 arm he brought. I noticed this when I picked them up side by side. The C-20 is much more stronger then the 1/2 arm. It has reinforcement places welded/riveted at the coil mount location, and 3/4 of the way on the underside. Definately want to use these with the bags !!

Man I had to 'heat & beat' those rusty u-bolt reminents out of the trailing arms....
-

[ChiefRocka]

More rust from trailing arm u-bolts....
-

-
Pads are on !!!
-

-

-
Old Housing...anyone need parts ??

-

Got her home...
-

-
CarLifts and Forklift make a great Team !!

Last few....

Hey John,
U da man! That looks great!

We need to be chosing a paint scheme soon for this frame.
Rich

[ChiefRocka]

I think we both know whats gonna be the color of this frame !!!!

Unless something has changed ?? Anyway, we will surprise the rest of these guys here later.

Actually, I still have to weld in some crossmembers, shock mounts, hardline mounts, rear valve mounts, etc, etc.

Also, what are we doing for a link ?? A panhard, or a custom Watts link off of that 14 bolt ?!?!?

Later....

[Reject]

looks great! got any more updates?

[ChiefRocka]

Thanks...yea its coming along. I'm working on the shock mount location and track bar.

I think I will reuse the stock panhard bar mount (frame side) and possibly make a new axle mount. Not sure. I want to make the panhard as long as possible.

I dont think a Watts will be neccesary here.

Pretty much rounding third right now.

New pics soon !

[ChiefRocka]

I took some mearsurements and ordered the KYB's for the rear. I ordered the 'gray' shocks as the 'white' shocks I believe are way too stiff for this application.

Also I plan on mounting the stocks at the rear-end, straight up and down, which is the most efficient way.

Here are some mock up pics of the rear valves and different tank fittings:

-

-
I thought the trailing arms would be the perfect area for the valves !! (JK)
-

-

-
This way of mounting the valves makes for a strong and sanitary install...
-

-

-
DARN IT ENOUGH ABOUT THE VALVES ALREADY !!!
-

-

[ChiefRocka]

-
-
I needed to use one of the plugged ports on the tank for fill...so what I did is drilled a hole thru the chassis, and used a Parker (of course) swivel 90. Other wise I would of had to use a Tee fitting at another port....not so clean.

Valve mounting:

[rcrahn]

Hey Chief....That's super clean!
Making progress! Keep up the great work!

[ChiefRocka]

You Got It !!!!!!!

[ChiefRocka]

Last night, I just finished plumbing and clamping all the lines down....wired the compressors, and airred it up for the first time !!!

The air system work flawlessly !!!

Pics should be up tonight....

All that is left are the front/rear shocks, track bar, and rear brake line.

Today, I will be installing a Fab-Tech 6 Incher on my buddys '05 HD....

Later

[ChiefRocka]

Here are the PICS finally....pushed it out in the sun on Saturday....

I have all the lines secured with clamps and tie straps. (white tie wrap are for the mock up....for the final we will use the pink ones)

Sorry multiple pics there....Back in shop for some wiring.....

All the valve wiring harness' terminate here at the left rear corner of the cab...
-

-

-

-
I was able to use the rear shocks up front....it ended up being a perfect fit as the shock were shorter. Upon reassembly (after powder-coat) I will shorten the lower cups 1" inch. There is plenty of shock travel left.
-

-
I hooked up a temporary guage...as you can see these 380's were max'n and peggin the tiny guage....
-

-
Extended...

-

-
I like this pic...reminds me of hydros...
-

[ChiefRocka]

Preppin for more welding....
-

-

-

-
These custom pieces of 1x3 lumber represent the bags at halfway...(aprx ride height)....trying to mock-up the panhard.....
-

-

-

-

-

-
The panhard might not work as I would like.....might have to go Watts...
-

Later....

[rcrahn]

ChiefRocka,
That's rocks!
Very clean and tidy.
I like it soooo much.
Go for the watts, just let me know what/if you need in the way of parts for it.

Thanks ironbutt.....

Here are the pics of the rear shocks mocked and working.


I tacked on a piece of 1/2" plate on the side of the notch...so I could drill and tap....
-

-
The stock lower mount was re-used and moved forward one hole on the trailing arm. I think it will be welded to the trailing arm.

Locating drill point...

The shock are working perfect...plenty of clearance.

I am going to drill and tap extra holes for adjustment location of the upper shock mount. This top hole is to be used if we ever go with a 'canti' set-up in the rear. The hole we will be using is actually going to be 3" lower...this will allow max lift with the bags in the stock location (the way were running it)

[Frizzle Fry]

Well done. I may have to go with longer rear shocks and move the lower mount to the arms on mine. What are the rear shock specs?

Just got in from a long Thanksgiving.....These shock were a perfect length and compression for the bag travel (8")...I will get you the part number shortly....

I should be starting the Watts tommorow....

Later

[PrerunnerRob]

Trucks looking sweet dude! I'm anxious to see how you build the watts link, how are you mounting it to the axle?
