 Made a new battery box for my new, spiffy 600 CCA battery.  Just enought room, I have to rewire some lines but its a BIG jump from my 250 CCA.  I will use that for the jd110rf

Heres a video, roughly 5 min.  I tried to talk over everything as to what I have done, minus paint and prep.  Most items are listed on the list uploaded to this site.

 

My last video with the engine running was.....well not worth posting.

 

 

Let me know if you want pics of any items,  and I will post quickly.

Well today was very.......spendy. Although I was able to hook up the manual pto and clean up a bit under the hood. I ended up spending some money on a new starter. It's nice don't get me wrong, but I had a good lesson today.

The starter would engage but not turn. So I troubleshot and decided that it needs some professional help. 145 bucks later I hooked it back up and turned the key. Same outcome, son of a, so I back checked all elec feed to the starter AND ....... Pos lead from the batter had come loos from earlier work. That was the problem not the $145 starter.

So I now have a new starter, a working pto and a nicely crimped pos terminal. Time for bed!

Heres the pto bracket made.  Its a 1" angle roughly 10 1/2" long.  Bolts are hidden behind the mess cover.

Wire alignment

PTO disengaged clearance

PTO engaged clearance.  Its really close.

I could use a smaller dia idler pulley.  This one is 3 1/4" with 1/2 dia shaft.  I have checked surplus, mccarfs and a local machine shop.  I think a 2 1/2" would be just fine.  Any ideas?

Ohhh, my new starter that I didnt have to buy :wallbanging:

 

gallery_53757_710_422659.jpg

 

all because of this wire ( need a icon with a guy getting kicked you know were )

 

gallery_53757_710_704380.jpg

 

 

You know the thing that really has my water boiling is that the service shop didnt call back and let me know it didnt need fixing.  Im sure that due to the loose pos wire, it didnt have a bad armiture, or brushes.  He could have said, nope your starter is just fine.  I would have continued using his shop.  BUT I have a new starter, good preventive maintenance and the glow plugs are next. 
I could have picked up a rear hydro kit, oh well :deadhorse:

I'd solder those cable ends so this won't happen again.  If you can find such a size, a 2 3/4" pulley would do fine.

Will do.

I decided to hook up the tiller today. I could not bog down the engine, just kept chugging.

I can tell the tiller rpm is slower than stock. So I mite have to take the rear pto apart and change to e gearing to get the tiller speed back to normal.

What rpm are you running the engine?  It would be costly to have custom gears made for the pto gearbox.

I will throw some tac tape and laser gauge it.  Im assuming the engine is at 3000 at lease, if not more. 

I have rebuilt the pto gearbox before.  Its not too hard, more costly are the mother deere parts. 

 

Id like to find what the operating rpm of the tiller is. 

 

 

I wonder if I will have to do that with mine


Tim

Not sure.  I went through a bunch of RPM calculations from the drive pulley to the driven and so forth.  The pulley on the engine is as close to what I could get for the space. 

 

Yours might be different.  Either way, fun to tinker and well this project keeps going and going and going :thumbs:

I wouldn't worry all that much about the RPM of the tines on the tiller.

 

The important 'number' would be RPM of the PTO when you are at full throttle.  You want that to be as close to the original factory speed as possible.

 

Some tillers do seem to operate at lower RPMs than others.  I know that the Bolens tillers seem to be a bit on the 'slow' side, but still work just fine.

  I am fortunate enough to be able to change the rpm of my rear pto with just a belt swap and can go from 2015 rpm to 2500rpm and the Bolens tiller does a WAY better job at 2500 than 2000 BUT it likes power :thumbs: !!

Pager450,

 Maybe you can use a bit smaller pulley on the bottom to get the rpm a bit closer ? If you need splines made into a pulley , like say 1"-15tooth you can get the pulley with a 3/4" hole and send it to me . I can burn the splines out on the wire edm easy peasy, or you could have it done at your local fancy pants machine shop that has EDM capacity. It should only take about an hour to do.

The stock JD 400 rear pto speed is 840 rpm. It is the only GT ever made to run that speed.
