Need Mechanic

[Jaylegger]

1st try uploading a photo. I pulled the head and will be sending to a machine shop. But I had one injector that was loose. If you look at the valves the rusty one was the loose one. Should I be worried about this if so what would the fix be. I have other photos am going to try to piece them together as a photo repair. And thanks for the recommendation on putting the tarp under the tractor it came in handy more then once!!

I'm not a mechanic but did own a Ford truck once so I consider myself more than qualified to answer anything vehicle repair related. I would think the rust in the cylinder would be indicative of coolant leaking into the cylinder likely from a breached head gasket.

I'm in agreement with others. That rust shouldn't be there.You can even see the rust on that piston.. Coolant leak somewhere caused that

Sometimes I just gotta believe in fate...

By the looks of your head it's a good thing you removed it.. now it can be cleaned up..milled if needed and reassembled with new gaskets and everything torqued properly. Have the machine shop check the valves while it's there.... breaking that waterpump bolt just might'a been a good thing.

BTW, I'm leary of making the upper engine too tight without addressing the rings, so don't go overboard seating the valve unless you're prepared to replace rings, hone cylinders, etc.... It could become an oil burner otherwise.

Good luck

Good job on the pics. Thanks.

Use some penetrating oil before removing nuts and head bolts...might not do any good, but take every advantage you can over breaking a head bolt or stud.

I like and use a good one, calle RustReaper. New and very effective. Don't use Kroil any more.

Good eye Cali. was looking at the same thing on the rust also and how it looked to be getting into the cylinder. I'm on my Mini lap top so it's hard to tell.But I couldn't see any signs of the rust on the gasket to the cyl. maybe were the oil is? No doubt have a good machine shop check the head for a Crack if it doesn't show any warpage.Thats IMO. and I'm Far from a expert.I also agree with Irwin also on going ahead and putting rings in it most of the hard work is already done and you will Prob. be good for another 30+ yrs.

Thanks for all the great suggestions. I will have the machine shop check it out. I was also if anyone can steer me toward a replacement for this part. I have a 2 piece exhaust I quess because of the FEL but mine is cracked and hoye does not have a replacment.

I cut the flange off one of mine and got a muffler from tractor supply and a 90 deg exhaust pipe from advance autoparts and welded mine together. Then I used 1200 deg black paint on it. Total cost $35.

That looks to me like the bottom half of the standard $90 (??) muffler that belongs on there. You might measure and see if the standard replacement will fit. Seems to me the loader builder would have allowed space for the standard muffler.

You might find that the standard flat muffler used on smaller Yanmars gives more clearance than the long round one that I think was original for YM1500.

Or just take the tractor to a muffler shop. (after it is back together). They would likely reuse that flange and build you a custom exhaust.

How about this?

The head gasket looks good, it's on the block, and unblemished. That crud had to leak out of the head after removal. I'm guessing the water got in through the exhaust.
