[QUOTE="KC743, post: 71572, member: 10199"] Need ideas. I am doing an overhaul on a 1989 743 that came with a V1702. It sat with exhaust uncovered, engine got filled with water, froze and cracked oil pan. Purchased a V2203 upgrade with intake to oil pan and mounts switched to fit. During shipping, the freight company damaged the engine. It fell on its side and crushed the small pallet it was on. Replaced fuel pump, throttle brackets, oil filter, small things damaged as it fell on the intake side. Installed and upon initial start up it had a strange noise. Turned off and double checked oil etc.. Started it back up and moved machine a little. I then raised arms all the way up, on the way back down I heard a critical noise, lost hydraulics and shut down immediately. I tried to restart but the new starter just spun like it was a stripped gear. I removed starter and it was perfect. Felt the teeth on the flywheel and the flywheel moved. I pulled engine and all 6 bolts holding the flywheel on were snapped with clean marks. I am assuming the freight company used a forklift on the rear fan when putting it on another pallet. Has anyone ever had this happen before? I tested the hydro pump by putting a pipe wrench on it and turning clockwise, it turns with no sounds, play, stutters anything. Feels tight with perfect splines. Any suggestions would be greatly appreciated! [/QUOTE]
