With the information on this site and responses to my previous questions my machine is in lots of pieces!

As I suspected, the right steering clutch and the main clutch were in very bad shape.

I have the following questions:

The red arrow shows links that are missing (broken off) from the attach points in the yellow circle. 

 

It appears that the cotter pin may not have been installed. The broken off pieces were in the debris in the bottom of the case. 

 

I think the links broke off when they impacted the bracket that holds the lubrication “cup.”
Could someone post a picture of this bracket so I can bend it back to the proper alignment. 
The shaft to the right of the yellow has about 1/4 inch of end play. Is that normal?

 

The next two pictures are from the gear shift mechanism. I studied the parts diagram but couldn’t determine the part numbers, could someone tell me the part numbers. Any idea if they are available anywhere?

 
  
 

The last two pictures are of the track tensioning bolt.  It has so little thread remaining that it will not adjust the track. Does anyone have this part available?
 



I’m also looking for a source to get all of the gaskets and seals I will need for reassembly. Is there a source or will I need to cut my own?

Thanks,
Chad
 

Gaskets are mostly available from Cat, Olson's gaskets is a good source also. Try Florin tractor or General gear for parts. Cat has a surprising amount of parts available also. BMR on this forum has a lot of parts and is great to deal with. I have a d2 parts tractor and might be able to help you out

There's a bushing that goes in the transmission housing on the clutch shaft. You can just drive the new one in from the top and let the old one fall down the shaft.
That bent arm with the yellow arrow is part of the interlock to prevent shifting when the clutch is engaged. The rod with the spring at the back of the clutch housing attaches to it. It should be pretty obvious where it needs to be when you try to hook them together.

I think this should cover most of your shifter

The D 4 6u I have had the same broken links, found wear in clevis's, pins, holes, clutch collar was allowing to much movement forwards of the clutch yoke and would hit the adjusting assembly where links attach, replaced clutch plate, filled and drilled clevis's and holes, new pins, new collar (fixed the slack in system) to reduce travel forwards to stop the clashing yoke and link corners.

Thank you for the picture if the inside of clutch housing.

Can anyone advise the reason for the D2 clutch dragging or not releasing? My machine drags to release the clutch occasionally (cold or at temp), a touch on the foot brake or clutch brake sorts it to release fully, seems a regular theme.

Hi John,

Thank you for the tip I shall check out how clean it is next time I need to adjust the clutch.

Cheers

My track tensing bolt/nut wouldn't tighten my track up---I added a couple of nuts behind the adjusting nut to get to good threads on the bolt
