D6 STEERING CLUTCHES

The D6 steering clutches ( D6 4R, 5R, 8U, 9U) and D6B 37A and 44A are the same design as the later D5 model machines, using the same inner driving drums, same bimetallic friction discs, same steel separator plates, clutch springs, and even the same brake drum and brake linings! Twelve (12) bimetallic friction discs and twelve (12) steel separator plates are required for each clutch pack. Unless severe damage has occurred, you often have to replace only the bimetallic friction discs. This keeps your costs down quite a bit. I would highly recommend that you check your brake bands at this time, unless you just enjoy pulling wrenches. All parts listed below are new replacement parts, non oem.
Brake Band relining kit $42.00 per clutch (a band is 3 sections, the price includes all rivets and linings for one complete brake band)

These bands will fit the D6 AND D6B DRY TYPE CLUTCHES FOR THE D6 MODELS 4R, 5R, 8U, 9U, 37A, 44A .
The part numbers for these bands went through quite an evolution as did the bands.   The early bands, for the model 4Rs and 5R's and 8U and 9U's did not have any reinforcing plates at the joints.  When the part numbers went from the "B" part numbers to the "F" part numbers, reinforcing plates were added to the "6F" and on all bands thereafter.  Upper Band P/N's 6B7484->6F6285->1M0547->8E7624  Center Band P/N's 6B7352->6F2686->8E7622   Lower Band P/N's 6B7241->6F2687->4M8766->9P0740->8E7625

WHEN REMOVING YOUR STEERING CLUTCH..........IT IS IMPORTANT TO RIG YOUR LIFTING SLING ON THE BRAKE BAND
PROPERLY TO PREVENT DAMAGE TO YOUR BRAKE BAND (CLICK HERE FOR INFO)
  This excerpt from a 1955 Service Magazine
is a reference for the D8 steering clutch but the principle is the same.  Do not damage your brake band!

CAT_D4_STEERING_CLUTCH_DISASSEMBLY2.JPG (186223 bytes) CAT_D4_STEERING_CLUTCH_DISASSEMBLY3.JPG (191597 bytes)
The "T" bar puller can be used with the center  push-bolt or a
hydraulic cylinder.
CAT_D4_STEERING_CLUTCH_DISASSEMBLY4.JPG (186527 bytes)
We have a lot of misc pins
laying around but this chunk
of steel fit perfectly.
CAT_D4_STEERING_CLUTCH_DISASSEMBLY5.JPG (181703 bytes)
On a D2 or a D4 the clutches
are pressed off end of bevel
gear cross shaft.  On
D5 D6 D7's you press off a tapered splined stub shaft and flange.
CAT_D4_STEERING_CLUTCH_DISASSEMBLY6.JPG (185380 bytes)
Removal of bearing cage and
bearing makes disassembly
easier.
Don't forget to remove set
screws in retainer nut!!
CAT_D4_STEERING_CLUTCH_DISASSEMBLY7.JPG (188198 bytes)
When you press down on the compression tool you want something to keep the studs in place so get a spacer to keep studs from dropping when you turn the clutch over.
CAT_D4_STEERING_CLUTCH_DISASSEMBLY8.JPG (190987 bytes)
You can use a press like we usually do but unless you do a lot of these clutches a simple piece of all-thread is all that you need.  Anchor it through your work bench or table.
CAT_D4_STEERING_CLUTCH_DISASSEMBLY9.JPG (192568 bytes)
Place compression tool and add a washer to disperse the pressure over the face of the tool.  Otherwise you can end up with a concave tool!
CAT_D4_STEERING_CLUTCH_DISASSEMBLY10.JPG (187226 bytes)
With your spacer underneath to keep your studs in place (shown above)
and compression tool on top
you are ready to compress the springs.
CAT_D4_STEERING_CLUTCH_DISASSEMBLY11.JPG (177407 bytes)
As the springs compress the end of the studs will gain clearance until the locks
are free from the retainers.
CAT_D4_STEERING_CLUTCH_DISASSEMBLY12.JPG (185189 bytes)
Remove all of the locks and be careful not to lose any!
When you put these back in you apply grease to the locks
keep them in place.
CAT_D4_STEERING_CLUTCH_DISASSEMBLY13.JPG (184208 bytes)
Release all pressure and remove compression tool.  You can now remove retainers and springs.
CAT_D4_STEERING_CLUTCH_DISASSEMBLY14.JPG (182223 bytes)
Now is time to check measurements on springs.
if any are shorter than the others by 1/8" it should be replaced. It is probably a good practice just to replace them due to low cost and the labor involved if you have to go back in there again!
CAT_D4_STEERING_CLUTCH_DISASSEMBLY15.JPG (186083 bytes) CAT_D4_STEERING_CLUTCH_DISASSEMBLY16.JPG (188792 bytes)
Now you can remove all the parts for inspection of discs and components.

Minor rippling on the inner drum is fine.

Make sure stud holes on pressure plate are not wallowed out or worn too far below the surface.
