These pictures show my interpretation of the tool group shown on page 249, Form 3253, D4 Tractor 60 Inch Gauge, Parts Catalog. This tool group is effective with serial # 7U36692.
These tools came with tractor serial number 7U40431.
3B3850 wrench (flywheel clutch adj.) is not used for clutch adjustment on this tractor. 9F3669 wrench is not used as the tractor has Henderson hydraulic track adjusters.
No screw driver 1B7973 or 3B2301 grease gun.
Look closely at the handle on the volume compressor - the decal for high pressure, winter and summer use are still readable.

This post is a supplement to the earlier post on Vintage Caterpillar tools.

 

would you please take some pics of your track adjusters sometime? i have a set that i got in some junk and thought about installing them on my D4
