D4 STEERING CLUTCHES

4G     6G    7J    2T    5T     6U    7U

The old D4 steering clutches, from the 4G/6G series, the 7J, 2T, 5T, and 6U/7U series originally used the riveted on lining style of friction discs. We can convert you to the bimetallic style friction discs and eliminate a lot of your steering clutch problems. We highly recommend converting to the bimetallic driving discs vs. the old riveted on lining style discs. This is an update to the earlier style clutches and cuts down on the possibility of frozen clutches and gives increased life and higher coefficient of friction to your clutches for a longer period of time.

Instead of using 8 friction discs with the riveted on linings and 8 steel separator discs, you will use 12 3F5504 bimetallic discs (sintered bronze) and 12 steel discs for each steering clutch. No other changes are required in inner driving drums or brake drums. You can, in most cases, re-use your existing 8 steel discs and merely add four more new steel discs to go with the 12 sintered bronze bimetallic discs needed for the conversion.

     NEW  !!!  BRAKE BANDS AND HEAVY DUTY LININGS

 D4_BRAKE_BAND_3B620+3B619+3B618_WOVEN_LINING_CAT_D4.jpg (279686 bytes)   NEW BANDS  !!!Sometimes your brake band is worn or rusted out so thin that it is no longer usable.   Sometimes it has some subtle bends,   slightly out of shape, or has wallowed out rivet holes or rusted out boltholes.  Often, if you followed service instructions for brake band removal, you probably destroyed one or two sections!!  This makes installing new linings difficult.   They almost always have broken off carriage bolts or bolts so old that they are no longer trustworthy.  We use a newer style of brake linings for these brake bands.   

For complete NEW 3 PIECE brake bands with the new style linings and all new carriage bolts, $267.00 ea  These will fit the early R4 AND D4 models 4G, 6G, 7J, 2T, 5T, 6U (early) and 7U (early) crawlers. (3 pieces, ONE EACH OF 3B0618, 3B0619, 3B0620)

IF you only need to replace one section:  If this is the case we will break up a brake band set and sell one section @ $115.00 but you will also need to replace the linings on the remaining sections so that you get equal lining height and distribution of braking force.  The linings for the other two sections with rivets has a cost of $62.00 total for both sections. TOP 3B0620 CAT_D4_BRAKE_BAND_UPPER__3B0620.jpg (235538 bytes)  MIDDLE 3B0619 CAT_D4_BRAKE_BAND_MIDDLE__3B0619.jpg (244482 bytes) LOWER SECTION 3B0618 CAT_D4_BRAKE_BAND_LOWER__3B0618.jpg (244199 bytes)

It is often easier and less expensive to just replace all 3 pieces @ $267.00

THIS TYPE OF LINING IS PRIMARILY FOR DRY TYPE BRAKES. THE BRAKE LINING KIT, INCLUDES RIVETS, LINING, AND THE HARDWARE KIT (BOLTS AND NUTS) FOR ONE COMPLETE 3 PC BAND ...........$84.00   We also have complete set (8 carriage bolts, nuts and washers) of hardware for bolt replacement of your old band hardware @  $15.00 per set
HEAVY DUTY WOVEN LINING WOVEN WITH BRASS STRANDS, DESIGNED FOR REPEATED USE IN SEVERE CONDITIONS, ABLE TO WITHSTAND HIGH TEMPERATURE USE (400 DEGREE)WITH MINIMAL LOSS OF COEFFICIENT OF FRICTION.  THE MATERIAL IS ALSO GOOD IN SOME OIL TYPE APPLICATIONS.   (IT SHOULD BE GROOVED FOR BETTER PERFORMANCE IN OIL APPLICATIONS)

The lining is easier to work with and you can even change position of rivet holes if necessary to compensate for bad rivet holes in the band.  This style of lining elminates the possibility of breaking, cracking, or chipping like the molded style linings which are brittle and must fit the perfect curvature of the band.   It is often tough to fit the molded linings to 70-80 year old brake bands without damaging that style of lining.  Getting proper clearances is even harder!

CATERPILLAR FLYWHEEL CLUTCH PARTS

Caterpillar made periodic changes to the cast flywheel clutch pressure plates and backing plates.  Over time most of the early plates have been cracked/worn and replaced with the latest update 2H6776 and the 2H6777 (2H8380) cast plates.  If have the updated versions, you are in good shape as you only have to replace the casting that may be broken/worn/warped or no longer usable.  If you have any of the earlier castings and have to replace one of them,  you will have to replace both the front and back castings with the later castings.

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.
