clutch parts pictures
Well fudge! I went to the yard today with plans of reinstalling the engine in the boat. This morning ,my friend who owns the yard, had a couple of his mechanics run the engine in the shop. After a total clutch rebuild they wanted to make sure it was good before it went back in the boat. The clutch was great but dang if there wasn't a tiny coolant leak where the heat exchanger slips into the coolant expansion tank.
I'll cut my mechanic a little slack because he did work me into his busy schedule and although he did have the exchanger out to have it acid dipped & the tubes rodded, he never ran it because he didn't have the time.
After trying to tighten the cooler assembly to stop the leak, the threads in the aluminum expansion tank gave up. Out came the antifreeze and apart came the whole newly assembled heat exchanger so a healicoil thread replacement insert could be installed (gotta love those things). Trans Atlantic shipped me a new gasket and I got a new pressure cap gasket while I was at it since the guys said they saw a bubble of antifreeze come past the gasket when the engine came up to temperature in the shop. The gasket was shot when I took the radiator cap assembly off of the expansion tank. I was thinking about replacing the whole cap and neck assembly but Sheri at T A said they would have to build one and it was $150! The old assembly started looking better to me after that quote anyway.
Ahh, the joys of a 40 year old engine...
That's OK. Another couple of days won't kill me and it's so much easier to work on the engine when it's out.
Oh, also, after talking with Todd the mechanic, I found out that we basically have a new clutch! I originally just wanted to replace the seals as preventative maintenance but they thought it prudent to replace the clutch discs. When Todd was in there to replace them, he noticed the shaft coupling was pretty etched and replaced it. Not bad but not cheap. He also checked the oil pump, nothing but 3 pieces...the pump body with 2 "gears" inside that move in an eccentric motion to pump the oil. The gears looked ok but the body was scored horribly. He said it was about the worst he had seen. You can easily see the scored housing in the picture. Again ,not bad but not cheap. Then...geez, I'm glad there's not but so many parts in the thing...then the input shaft had some etching at the spline so it got replaced too. That thing was REALLY not cheap. I think all that was reused was the housing and a couple of washers! I'll be glad when this years preventative maintenance phase is over!
Again, the joys of owning a 40 year old boat. We do enjoy the boat, though. Good thing.
