    Default Our new D4C 40A dozer

    Hello,

    First post. Last week we just got ourselves a 1961 D4C 40A. Been sitting at least 15 years. No batteries, a squirt of ether and pulled about 6 feet and she fired right up. Loaded it up and took it home and put new batteries in it and replaced most all of the fluids, filters and a grease job.

    My first time on a older D4, had a Allis HD10 a while ago and ran D7G's in the Army.

    Anyway, it had new sprockets etc, not too long before it was parked. Fine machine. Did a little dozing today.

    Only on issue so far, no (does work sometimes) turn right going forward. Left forward, right and left reverse work great. Apparently brake not working right for turning right going forward. I bought and received the service manual, so I will see how to adjust accordingly. Give it a try anyhow.

    And, I have a picture of a short shaft that comes out of the back of the cylinder head, which has a nail (?) in it. It turns a quarter turn, but we have no idea what it is or for. Any help would be great.

    Thanks,

    That thing at the rear of the head is a compression release. Very handy thing. I like the heavy duty radiator guard actually I like the whole machine. Charlie

    Thank you for that information. Will so some research on that.

    Its an old Michigan DNR machine from the U.P., hence the cage, etc. It had chain boxes and a guard with hoops for hanging cables on the back that was smashed that I took off. Now one can get to the fuel drain and shut off. Not sure how they would have done that.

    Thanks again,
