[QUOTE="SkidRoe, post: 99703, member: 3290"] Glad to hear you got it fixed. Good catch on the pintle seals, I sure would have overlooked that one. One thing I do notice about my 440b is that if it sits for a while, it is like the gear pump loses it's prime. It is regained again within seconds as soon as you start it, but it takes a few minutes of use for the air to work its way out of the system again. The place that you notice it the most is in the boom lift cylinders - they will be a bit jerky for the first couple of times that you lift the boom. I have never really labeled this as a problem, more of just an idiosyncrasy of an older machine with a bit of wear in it. Cheers - SR [/QUOTE]
