This old D7 pipelayer had sat for 30 years until a young club member (the guy in the black shirt) brought it back to life. At present, he is missing the 3 loose blocks (boom hoist, boom point + hook block), and only has part of the counterweights. Predecessor of the 572. The casting numbers on the hoist don't appear to be CAT numbers, so it was probably built before or just after the Trackson merger. The rear end whine has been diagnosed by an old CAT guy as ring gear, not finals. Since the machine won't be worked hard, it will probably be left as is. It is quiet in reverse. At the National Pike show, Brownsville PA, May 18, 2008.
