     NEW  !!!  BRAKE BANDS AND HEAVY DUTY LININGS

    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 THROUGH #12117) and 7U (early THROUGH SERIAL# 40736) crawlers. (3 pieces, ONE EACH OF 3B0618, 3B0619, 3B0620)

If your serial number is 40737 and above, you will use the later style brake band 8Y6306, also at a cost of $267.00 ea

THIS TYPE OF LINING IS PRIMARILY FOR DRY TYPE BRAKES. THE BRAKE LINING KIT, INCLUDES RIVETS, LINING.  $57.00 
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.

D4 STEERING CLUTCH DIS-ASSEMBLY IN PICTURES

		The "T" bar puller can be used with the center  push-bolt or a hydraulic cylinder.	We have a lot of misc pins laying around but this chunk of steel fit perfectly.
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.	Removal of bearing cage and bearing makes disassembly easier. Don't forget to remove set screws in retainer nut!!	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.	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.
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!	With your spacer underneath to keep your studs in place (shown above) and compression tool on top you are ready to compress the springs.	As the springs compress the end of the studs will gain clearance until the locks are free from the retainers.	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.
Release all pressure and remove compression tool.  You can now remove retainers and springs.	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!		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.
