Here's some pics of a NOS Caterpillar D4 tool kit I added to my collection a while ago. Most of the tools Cat used were provided by other established tool makers, the double end wrenches are almost always Billings with the Caterpillar part number stamped on them, some of the other odd wrenches are Armstrong and Vlchek also carrying Cat numbers, the grease guns were either Lincoln or Alemite, the track grease pumps were Alemite, and some of the special parts like the fuel injection caps and the feeler gauge in this set actually just have Caterpillar on them.

I remember seeing this box of caps & plugs for our 7U machine, ... back in the '70s. Now I'm afraid I need to replace the head gasket and worried about getting dirt in the injectors. The probability of finding this box isn't very high. My parts manual shows some 4-caps for the injection pump 2F2989, injectors 5F2807, and 8-plugs for the lines- 2F2990 with a solid filled triangle next to the part with a footnote showing shipping & storage only. Are these the parts in the "do not open" box? Is there a part number for the full set?

I just entered these numbers on the local Cat dealer's online parts order web page. The first part doesn't show. The second is in stock at $0.50 each, the third is also in stock at $0.21 each. It seems like the first two caps ought to be interchangeable.

Thoughts & comments from the experts?

Some shops have the correct caps for a particular manufacturer. Most places the mechanics use plastic caps as they are cheaper and more easily replacable in cases of lost, damaged, loaned out and not returned. I use plastic caps on most Injection systems I work on.

Toby,

In the first photo there are two sort of "T" shaped tools in the upper right hand of the pic with what looks like pins laying next to 'em. My question is what were they used for? They look more like hood latches than anything else.

drawbar stops.

hhydro,
not a x spurt but,
The alum.plugs and caps have been replaced with plastic using the same part #.The caps in the box are two heights.

Check the threads, I believe the caps and plugs are regular -06
(3/8" nominal) 37 degree JIC flare fittings (9/16"-18 tpi)

That's what I found when I picked up the parts using the number from the 7U D4 parts book. They were yellow plastic caps and plug, but the caps were all one height. The caps go on the injector and pump while the plugs go in the nut on the tubing.

Thanks
