flywheel locked

ok. how exactly do i get the rotted part out that is still screwed in to the block? should i drill it out somehow?

back to the other problem....

got the starter off to check the bendix gear? looks fine and turns over when not attached to flywheel. removed flywheel coverplate and tried to get it to spin, no dice. removed plugs and sprayed that anti rust lube stuff down there maybe it will free up...

Is it possible for the transmission to lock the engine? How would I check regarding that possibility?

more info? I have no idea what I'm doing, and I probably broke this engine. I took a picture of the pipe that corroded off the block. what other pictures would you like? Seriously.

Stay cool. Do you have a temp gauge? If so what was the temp when the engine stopped? After it stopped did you try and crank and it did not fire? If so, then water could have backed up and flooded/ seized the engine. Is there absolutely no movement when you try to turn the engine with the hand crank? A-4s are very resilient so give use all the info you can, do a replay of the event. Easy for me to say but some little detail could be the key. Continue to soak the pistons/valves with MMO.

Trumps....as Dan said...cool out for a bit...we'll get it back. We need succinct and precise info...easy, brother.

Remember, it's a sailboat...as much as we love Atomic4's, it only helps us get to our destination. The boat is still good with a (temporarily) broken motor..

Replay the events of the delivery and try to relay to us what happened...we'll help you figure it out.

FYI...I am the solution to Trump's issues. I did not realize that Benny was reg'd on here, but the boat that I have been working on is the same one that he was referring to. I AM an engine guy (although no sailor by any stretch of the term,) so we have partnered to get this beast on the water. To date, the lower bearings were seized on the original engine. I believe that he had sailed her without opening the cooling system, but that was before my time, so I cannot directly comment. I DO know that the crankcase was full of what we engine guys refer to as mayonnaise, so I suspect that something cracked as well. He couldn't afford the cost of me line-boring and rebuilding. Regardless, old engine out, new one in (courtesy of a member on here in the classifieds.) At present time, he and I are off to play disc golf. Later today I am hoping to align the engine and rewire the electronics for the starter and alternator. I still need to track down graded bolts for the coupling, which is made more difficult by the fact that I can't find the original three bolts. Also, the original alt was a one wire delco, and the new is the two wire motorola. Should be a snap though. I will probably source the indigo ignition kit as well as a new fuel pump, given the issues previously stated with the current pump. In the meantime, Benny will be pumping a fuel ball.

H3 - that is an interesting turn of events.

You can get some mayo in the crankcase by cranking for too long during a non-start incident..it backs up the hot exhaust section and goes downhill from there.

Someone here knows the coupling bolt details. I can hunt them down if needed. I want to say 3/8" fine thread x something like 1.75", but that is off the top of my head, sitting at work.

Plan now is to get her ready to sail, and I'll rebuild the original A4 in my spare time, then swap it back in and rebuild this new one as a spare, or maybe sell. Dunno yet.

I tried searching forums for the bolt specs, but couldn't find 'em, so if noone chimes in, please lemme know when you get home. Thanks!
