[Complete] John Deere 110 "Sub-Compact Tractor" Build [2018 Build-Off Entry]

OUCH!!!!!!

Looks like water were in there. You should take the Engine apart again, take out the piston, and hone the cylinder. Then remove all the buildup with a wire wheel, lap tha valves, put everything together, remove the rust off everything before reassembling it, check the injection stuff, if everything works correct, and lube up the cylinder, try to fire it up again!

Personally i find it hilarious.

So W, what now?

Bet that kohler doesn't look so bad now, eh?

Oh the Krahper would need soooo much more, and be way less powerful.

Yeah I guess that's the plan.

You have a strange taste of jokes.

I guess fix it. I'm too stubborn to go back to that Krahper.

Oh dear. Must have sat outside for a while. I wouldn't take the piston out, try rubbing the cylinder with very fine emery cloth to get rid of the rust and clean the carbon off everything first to see if it starts. Try using a blow torch in the air intake when you try to start it, should help ignite the diesel. Clean out the injectors too.

No I would definitely take the piston out. Might as well hone the cylinder evenly and get a nice even crosshatching on the entire cylinder wall, then it'd be like starting with a brand new engine.

The water damage sux man.  Doesn't look too bad.  Keep up the determination, get it cleaned up (honing, etc..) and try again!

I think that water damage should actually clean up pretty well.  I'm still pondering what might be going on with the injection system as to why it didn't start.  You might want to dissassemble or troubleshoot that too.

He should just put a p7100 in it lol

Play nice.

He did say that it was spitting diesel out of the exhaust, so I assume the injector is working. You can buy an injector for these engines for cheap if you need to.
If it's putting diesel out the exhaust that means it's not being ignited, so using a blow torch as I said earlier would help to ignite the fuel. Possibly didn't ignite because of the rust/water in the combustion chamber preventing the fuel to burn. Or the compression isn't good enough to ignite the fuel by compression ignition.

Linky no workie....

Does sound like a compression problem.

What were the valves lashed at?

so whats it mean to hone a cinilnder, are you sanding it or something?

I think of it kind of like a rough polishing of the cylinder walls to make them geometric and take out abrasions and debris and some scratching and scuffs. Done with a special tool.

It's a form of grinding that can take a glaze, pitting, or scoring out of a bore and leave a crosshatch that'll help with compression.

Wonder what kinda shape the rings are in with a bore like that

Cross-hatching plays a big part in cylinder and piston lubrication. Basically a good hone job would make it like starting eith a brand new engine. I doubt that cylinder is the reason it's not starting though, maybe warming the air up like Matt said would help 'er out.

Yep, I'm going to.  Thanks!

I don't think it was the injectors, it was probably the standing water in the cup of the piston.

A guestimate, I couldn't find specs on it.

Tore it down tonight.






I bet I have the ONLY 7 horse Yanmar with DIRT in he bottom of the crank case.  Must have gotten in where the drain plugs weren't.

Well, I guess I'll do some valve work and hone the cylinder, reassemble it, and try again.

That gate swings both ways.

Couldn't see the piston well. How were the rings?

Yep! The Yanmar needs to be rebuilt!

I wish I could help you there, but I spent my last money on Murray Widebody.

Really good, surprisingly.

LOL thanks but I can afford it. I have enough money, I'm just a stingy old miser. lol

Good deal, should be able to clean it up nicely.

gotta get er going before these flood rains stop. you wet down in texis? i wold be really bad off if i did not live on a summit.

Yup!

Heck no, it's dry as a bone down here. All the creeks have dried up, no rain for months, the grass is all dead, starting to lose a few trees.

Got the engine torn apart:



Will have to order some parts, then I'll get it all together again. Also need to buy a torque wrench.

What are you buying for parts?  I'm guessing rings.

Now that you have that crank out you better get it turned down.
