1966 D6C Powershift Won't Shift to Neutral - Linkage Adjustment?

The skids/shoes/training wheels on the D2 D4 sized machines (toolbar blades) are generally on left/right sides directly behind the blade and slide in/out with adjustment pins. That looks like it is directly in the center of your C frame. Someone with blade attachment literature/library? can ferret out what that is. JM

That almost looks like a ripper pocket someone added on. Maybe they set it up to pin a shank for use without a blade or if it measures proper, you could slip a detachable foot on it(a wide one). Nothing in my 7A book that I dug from the shelf.

That almost looks like a section of track rail that was welded on to the frame. The multitude of snow blowers I was associated with had "shoes" to help carry the weight of the blower heads. They were simply plates of steel with beveled or upturned ends so that did not catch the pavement. They were held by recessed plow bolts. You could simply fabricate a "shoe" and attachment so they could be easily replaces as they wore. On a dozer, I really do not see a need for shoes. Deas and others can certainly provide better insight. -- cts

if the blade creeps down it can be that the cylinder need a set of seals. if the cylinders get hot that can be a sign of them bypassing internally.

it is better to strip them and rebuild before they get real bad.

it can also be issues with the pump or the valve bank but do the simple thing first and rekit the rams.

There are 4pm these “brackets” under there. I will get some better pictures.

I have been looking for the seal kits a little and have not had any luck. My cylinders have 4J3569 on them. I have found the seal kit part number 7X2664. But this Fits Cylinder Numbers: 5J8172, 5J8173. I suspect that since mine was made in Japan that the cylinders have different part numbers than the models made in the US. I am going to measure them and see if I can make any progress that way.

Having the Japanese made dozer is proving to make things a little more challenging.

Hi, Jprice1101.

I found when I was working on a ranch in CA. that I had to ask the parts people to look under "Classic Caterpillar" for parts for some of the older machines. Apparently the front line parts lists only go back so far. Hope this helps.

Just my 0.02.

Original cylinder group for that machine would be 4J3456.

I would like to thank everyone who has provided me with their knowledge and insight!

Hi, Folks.

The 'elephant's feet' pads for holding the 'dozer blade up weren't bad when all you were doing was spreading.

How-wevver, they were a TOTAL PITA if you also want to do some digging with them installed. My advice would be to get used to controlling the blade without them. Learn to let your eyes and the feel of your favorite rump steak on the seat tell you what the machine is going to do next and use this information to help you work the blade to keep it where you want it to achieve your goal. Handz-on experience is certainly the best way to get good at this.

Just my 0.02.
