Gotta pick the minds here in HEF again...I have an '80 CK, C model w/extend-a-hoe. The boom won't lift high enough to even begin engaging the travel lock. I have to roll out the bucket and push the boom up with the extendahoe until I can hit the boom-down to grab the lock. When I release the boom, I can push the pressure off the lever, and then ease it down until it gets to that (i'll call it slack, or sag in the cylinder pressure) point and then it free-falls until the pressure builds (about 2-3 ft at the top of the boom) and bounces in the cylinder while it bucks the machine at bit. definately seems like air in the hydraulics, but I would have thought it would purge that out after cycling a few times. It's dangerous at best, but it can't be godd over time jerking the machine around so much.
Any knowledge? symptoms? cures?
