A "G WAGON" OMG

Yes ...definitely spendy...

Gonna have to pass on that one...waaaaaaaaay beyond my pay grade...

Would be cute though.

All fun's and games aside....I am getting into the Cab forward idea though.

Just gonna keep plowing along on the drive train and see what shakes out

Using an Isuzu cab would give things the look of a Pisten bully.

Paint it red and it would really look the part....

I sent Bud a PM

We'll see what shakes

Thanks for the idea......

There has got to be a dead Suzzy out there that needs a home....

More parts slowly drizzling in.

The outer pinion washers for the OC12 showed up and the steering band shaft seals.

With the washers here I can start getting the compensator case back together.

All the rest of the parts are cleaned up and ready to go.....

The original steering shaft seals were very thick with another steel piece in them to act as a rod guide,at the last of our running sprytes with the oc12 differential we double stacked the seals. The hole in the differential is deep enough to do it.

I have no idea the cost of a body but GMC and Chevy had some neat looking snub nosed COE trucks in the 30ís and 40ís Would be a unique look.

Loggah...
Mine was a mess (Entire thing was trashed by the previous crew)

The seals were mashed to hell....likely by an idiot with a hammer.

I can spin up some aluminum guides to fit behind the seal and help keep the seals alive??????

Jim

Those COE rigs will fetch big $$$$$

I am gonna keep my eye open for a Suzy cab forward.

Since they are made as a tilt cab already...will be easy to adapt it to the front of the 2100....

The old GMC COE are cool, but the restoration dudes will be all over anything decent.

OK

Today the diffy compensator went back together.....(HEAVY!@#$%)
I do not have an easy way to lift that beast up on the bench....so put down a piece of heavy particle board on the concrete floor.

Worked down there where it's safe...

That sucker went together quite well.

Greased up the new thrust washers I added to the setup....got them all in.

Timed the skinny pinions and got them in.

Just kept adding parts until the bench was bare (Except the old thrust washers and used cotter pins)

Cut some exhaust tube to be temporary fillers in place of the carrier bearings..

Wanted to keep the drums from falling off.

All nuts tight...just need to get a box of cotter pins and get 12 of those bad boys in place.

The unit turns very free all the way....

This is not my first Rodeo on one of these....just never did this big of one.

Last one I was in came from an Oliver HG (About the same as the C4 used in early Spryte)

Before that I did an OC6 crawler and an OC3.

But this was when I was in my early 20's.


Same game pretty much.....


I am going to be very happy when this bad boy is hanging back in the 2100.

Tomorrow the case gets washed out.

Still gotta order the gaskets from Snow cat Pat....

I can get the gear set back in and the drop boxes on....

Still need more of the 6014 bearings to finish the beast.........


WHAT A MESS THIS WAS.

Happy that it's usable is about the best thing....

A couple pix....

Gonna roll that sucker into a big plastic bag to keep it clean for now

Thank you.....

YESSSSSSSSSSSS

That's what I got planned

Put the bands on the drums....cinch up with a zip tie to keep them from being a PITA while stuffing the diffy carrier into the box.

As the thing is all the way down....this is he way to do it..

The new band material is a tad stiff...

Same stuff, just thicker due to being new..

The old stuff was nearly to the rivets....


GREAT FUN

Cleaning up the drop box covers and the axle tubes this morning

The threads in the drop box cover are in bad shape on about half the holes
Some threads there, but not good enough

Going to countersink the holes from the inside and thread in flat head Allen bolts and locktite them

This will make a very sturdy repair of the area
The other option is to Helicoil them

The tool kit is one I do not have on the shelf

Gotta head to town and get the bolts in a bit

Will post pix later

Had to go to two different bolt companies (Less than 1/2 mile apart) to get the 12 ...5/8"-11 Flat head Allen bolts 2-1/2" long (Full threaded)

Stuck the one cover in the mill and dug up a big azz countersink.

Dropped that bad boy into the inside of the 6 holes that fasten the axle tube on.

Got the holes all ready for the big bolts to thread in.

Gonna wash up the axle tube now (Very grungy with a huge amount of blue silicone on it and nasty goop left from the water oil mix left behind..

Then will come the acid test.....SEE IF IT ALL WORKS.....

Gonna fit the bolts with Nylock nuts and the original washers..

With the flat heads sealed with blue locktite they will not leak oil....



Pictures in a bit....

YES INDEED.

Never had one of those rattle loose.....

Well...
To start with...the previous crew was consistent....and this is not a compliment either.

The fools crammed a standard washer under the bolts that held the axle tubes on...
Sadly there is a spot face in the axle tube that will not allow the washer to seat....

RATTLE THE BOLTS DOWN UNTIL THE WASHER FITS....OMG


The threads were tore up in several holes.

One had a fine threaded bolt run in and it was a bitch to get out....

Cleaned up the hole with a tap as best I could.

The threads ended up a tad out of square....but things fit OK.

PIX

Counter sinking the holes.

Holes done.

Locktite added.

Washed the threads with brakekleen to degrease well first..

All done.

Ready to go back together...


The drop boxes did not come off the same cat either.

One had a soft green paint under the black.

The other one does not have the green paint..

A cat of many colors.

Not a real Gung ho day today.

Got the other axle tube cleaned up.

Both drop boxes are all spiffy now too.

Ordered the gaskets from Snowcat Pat....

His lovely wife got things all handled....

THANKS FOLKS....

Spent more time on ebay snooping out more 6014 bearings for the drop boxes.

Two coming out of Macedonia.....great price too..
One coming from California
One from New York

Enough so far for one box.....

But the prices are averaging about $20 each.....

When ya gotta have bunches...ya got to shop around.

I am not excited about the Chinese bearings...but several of the big name U S companies are getting their stuff made over seas.

I have found so far

MGM Radak
SKF
PEER
BL
A Chinese made one called "Premium" with just the number on it.
NSK
Link belt

Should have more at the post office tomorrow.

Even the local wholesale bearing houses are pretty spendy on the bearings.

The two pinion bearings cost $80 for the pair...The big roller bearing just behind the pinion is more expensive than the other bearings....and tougher to find
The two main carrier bearings $50 for the two

The 8 bearings for the drop boxes are all over the map.
$19...$15...$27 each (Two out of Europe were $54 for pair)

Still watching a couple sellers.

I want to see what the stuff I bought looks like.

If good..will buy more...

Ratty old boxes is fine as long as the goodies are in good shape...

I will be real happy to have the big gear box back together and in the cat...


(1) 6309...Pinion at drive yoke
(1) 1310...Pinion at bevel gear
(2) 6311...Carrier
(8) 6014...Drop boxes
(2) 5210...Axle shaft outer end by sprockets

A metric buttload of bearings...

A note to anyone snooping about to find bearings.

Avoid bearings marked "C3" these are a looser fit bearing (Internal clearance)

The 1310 roller bearing behind the pinion gear is an odd duck.

This bearing needs to be a caged roller bearing and NOT "Full compliment"
The Full compliment is rated at 3000 RPM MAXIMUM (Drive shaft RPM)
The 1310 is available in many prefixes and suffixes.

The one I got is an MS1310EX...This bearing has a inner race with a flange on one side and a side plate on the other side.

This bearing will work in this application as the side plate will be captured by the center tube on the pinion shaft and this keeps the bearing solidly located.

This bearing is good for 5600 RPM....

The 6014 can be had as
"OPEN" no seals or shields
"ZZ" suffix ...both sides shielded with metal shield
"2RS" both sides sealed with rubber type seals
The shields and or seals can be easily pried out/off and tossed to give an open bearing.

The 6309 is about the same deal

The 6311 is also the same game

The prices on ebay are very good...

Just avoid the C3 designation and you can remove the unwanted seals or shields and toss them.

The Japanese and European bearings are top notch as are the US made stuff.

The Chinese bearings are in many cases made to ISO9001 standards

I have not had much experience with bearings from that side of the pond.

I did put a front wheel bearing cartridge in our 2007 Avalanche 4x4
It was a CCCPP brand.

Been in the rig 2 years now and no issues.

Fit and finish looked great....

Guess I am just a tad cautious on the bearings for the cat.

I think the larger bearings in the sizes needed for the OC12 are just fine from the folks in China.

I will not start a debate on the merits of any particular brands.....

The only bearing that is finicky is the 1310 pinion bearing due to the many configurations that it comes in.....

You can get great deals online...just be sure and pay attention to this bad boy...


Hope all the bearing stuff help someone...

I beat my head on the wall for many hours sorting out all the prefixes and suffixes stuff...

Most of it is not a big deal...but some can be....

A pix of the one pinion bearing to stay away from.

These are called "FULL COMPLIMENT" type and will carry a bigger load...but the RPM rating is less due to MORE INTERNAL FRICTION

Just an FYI
I ordered the full compliment bearing by the number only...then got to looking at the bearing when it got here...then asked What is the difference and why.

Reading bearing specs books will make you crazy.....and make ya want to chew the tracks off your cat...

All for now....

Tomorrow gotta wash out the main diffy case and go get a 9/16" hex tool to get the drop box oil plugs out.

The small 1/8" pipe drain plugs were stuck tighter than a bulls azz in fly time.

The hex striped out..

Drilled them and used an easy out.

Re tapped the threads to clean them up..

Will install new hex head plugs there...

The carnage never ends with this cat....

OK

The diffy case finally got the washout and clean up.
The case lid was really grungy too.

All spiffy.

While looking for something in the shop I spotted two screw jacks that likely came from the old square body Suburbans.

These will work great to hold the Compensator case in the center of the bores of the main case while the drop boxes are tapped into place.

I picked up some steel angle that can be used to build a pair of holding fixtures.

The rusty pipe in the one piccy will be cut to length and welded to the angle.

The angle bolts to the top rail of the case and this will allow the case to stand free with access to allow the drop boxes to be fit easily.


A pair of tubes (Not shown yet) will slip inside the compensator case and then rest on the jacks.

SPECIAL TOOLS YA KNOW

I picked up another 15/16" box wrench to modify and make an opposite hand wrench to the one I already made..

This is needed to get onto the very bottom bolts in the drop box.....

(Flat head 5/8" bolt)

These two wrenches are a real help....

Pics of the case.
All threaded holes tapped to clean the threads.

Happily all the holes are in good shape...

I WOULD NOT HAVE BET ANY $$$$ ON THIS ONE...CONSIDERING WHAT HAS BEEN THE NORM...

As the jigs and fixtures come together I will post pictures.

I like things easy....especially when the stuff is heavy.....

Keeping the compensator centered will make getting the drop boxes on real easy.....
with a soft dead blow hammer.....

No steel hammer on this maneuver ....

At present...the plan is to install Allen set screws in the 5/16" threaded holes in the top of the case, then fasten the top using Nylock nuts.

This will save the threads in the case and make a better overall fastening of the cover.....

I may use blue locktite on the pseudo studs....not sure yet.

Best part is the Allen set screws have a hex in them and can be removed easily...
