100$ Dation 16HP MTD 990 "Mud Train"

Oooh, I thought you meant spark timing. My bad.

For the valve timing all you gotta do is make sure the marks line up on the cam and crank gears.

well i got a problem, i dont have a dot on my wight. if its on the gear, well theres a bearing over it, i put a few dents in the bearing trying to get it off.

well i never got the bearing to buge and that thing is hard to turn and it clicks alot now. but i have determended that the fly wheel seems to be 180deg off axis for when i wold need the spark. the pistin and valves seem like there moving at the right time. dont know how im gonna get the fly wheel off, i already broke bits of it my last attemopt

only ay I know of would be a piston stop of some kind, you can fill the cylinder with rope, or find a bolt that can thread into the head at the sparkplug hole, but you do run the chance of causing some damage to the top of the piston doing this, I prefer the rope method my self because it does not damage the piston, the only other method I know of is to purposely hydro lock it

im trying to jam the fly wheel up and shock that nut shaft thing off, letting soak in some PB overnight first

well today im going to taclke the motor agin, looks like the rain has stopped. im not jamming the cylinder because i will break the connecting rod.

ok, got the nut off, now the fly wheel is stuck on the shaft. and its rapidly loosing teeth as i try to get it off.

Put the nut on the crank (2-3 turns), spray it with liquid wrench or wd40, and hit the nut with a hammer. If that doesn't work, at least my local AutoZone will loan pullers.

pullers?

Flywheel puller.

If you are good and know where to pry, a prybar and a hammer will work.

well that thing is starting to look like a hick from kentucky, i got pissed and went ape sh*t with my sledge hammer. its missing alot of fins... still wont budge!

Doesn't exactly put a smile on my face seeing an old engine being treated like that.

Oh well, probably time for a Honda clone or something.

Like I mentioned earlier... I wish I was 1200 miles closer.  I would have taken it off your hands.

i got 1 more thing to try today, if that failes then im going to a 12hp cast iron briggs. as far as the 16hp motor goes, i dont care how much i mess it up if i can get it to run agin. i dont see the point of having something that dose not work.

I DID IT, JUST NEEDED SOME OVERKILL!

So this engine had a sheared flywheel key all along.  I wonder how a flywheel puller would have worked on this.

well i have never seen one before, and i probably wont in person.

a little end of the weekend progress update. i got the fly wheel installed with new keystock and that nut back on. it sucked to get on about as much as it did to get off once it broke free. i had to go to a family get together dinner thing, but the time i got back it was 5:30 and i did not have much light left under the trees. i cleaned up the gasket crap between the 2 halves of the motor, and found 2 of 4 bolts and washers. then i threw a tarp over it and cleaned up for the night. its basicly going to be sunset by the time i get off work for now on so i cant make progress on this during the week anymore. so see you guys in 4 days.

oh, damage or not, i think this motor is going to run, and im actually really exited that i have been able to save the stock motor, hopefully the fly wheel was the only problem, and that bearing i damaged dose not explode or something.

I seriously would not run that flywheel after the way it was treated. There's a reason we don't smack flywheels with steel hammers. Did you happen to put a new crank bearing in to replace the damaged one?

i cold not get it off, it still rotates, if it goes i guess i can dremel it out. but as of now im using what i got. also i wielded the broken off bits to the fly wheel back together, shold be relatively balanced agin. for a governed setup i think that is more than enough. i run dinky ungoverned with bits of the blower broken off on 1 side with no problem.

i cleaned up the bottom part of the block alittle before i threw it together.


tomrrow i tighten my bolts, put some oil in it, rap a pice of a rag arround the intake with alittle gas on it, and try to give it some pulles, see if i can get alittle life out of it.


if i get that life i will cut grind and weld if need be something up to replace what i stole from the governor. if i still have daylight then i beginning installing and assembling of the 990.
if i have a successful test drive of the tractor befor or during the weekend im using this paycheck to buy some new tires for the rear.

oh, if i get it running im also cutting off the rest of that rusted out non functional muffler and welding a diffrent one on.

some more updating
