Thanks for all your help, I got it up and running, sounds great! I still have to pull the front wheels off and pack the wheel bearings and check the fluids in the transmissions and such. The bearings are new, but I will need grease seals, luckily I have a parts manual, hoping NAPA can do an interchange and get me the correct seal. Oh, I did operate the hydraulics and they work good, don't see any leaks yet!

Don't know if this will work, but I posted a video of the engine running.

I take it there is no charging system on these tractors? Anyone put something on to keep the battery charged?

There should be a charging system Kohlers have and alternator / stator under the flywheel it would be a 15 amp systemgenerally on the LH side of the engine same side as the starter there should be a spade connector plug with 3 slots 2 wires coming from behind the flywheel / bearing plate they are the ac leads from the stator the other wire is the ignition wire. the 2 wires from the stator go to a solid state rectifier voltage regulator from the VR a single wire goes to the ignition switch. There are a number of VR that work on the Kohlers the older models were mounted on the backside of the dash on the PK and the newer engines had them mounted on the engine blower hosing. heres a couple of pics 1 being the older style and 2 being the newer type

Here's a couple of pics of the VR mounted on the tractor

1 older style on the dash  2 the newer type on the engine on the 2nd pic you can see the wires from the stator

I finally figured out youtube! here is a video. I just installed a new fuel pump, but the filter is not filling up with fuel. I pulled out the petcock and removed the screen, which looked dirty. What do you think, does it sound ok? I don't have much excerience with these little engines, but it sounds like it may not be running quite right.

Yes, I have that on mine, but when I disconnected the battery, it killed the engine. I'll check it when I get a good battery, I'm just using a jumper box right now.

Thanks.

Good Morning, the engine sounds fine to me, the fuel filter many times will not fill full of fuel as long as the engine runs its fine, the engine will stop if the battery is disconnect because it has what is called a battery ignition system it needs the battery for it to work its not self generating. As for charging use a VOM or voltmeter to see what the voltage is with the engine running it should be close to 14 V DC.

Ok, new problem. I did change out the hyd fluid and all was good for a while, but now when lifting the bucket, it gets a little jerky and will not lift much. I'm am thinking the pump is going out, but hoping it is something else! ;) When I filled the hyd reservoir, I filled it to about 4 inches below the vent plugs on top. it would be nice if they had put in some kind of gauge to see where the fluid is at.. Know of anyone who handles these hyd pumps? I haven't looked anywhere yet, this just happened yesterday.

Thanks, I figured that out. I put a battery in and it is charging. It has been running good, other than the hyd problem it just developed.

Sounds like it's sucking air ... (not enough oil) < jerky.

With the cylinders all sucked in ... the oil tank should just have enough below full for expansion.

 

Could also sound like the pump won't pick up oil & prime it's self.

Cycle the bucket up & down many times with no load.  See it the air will work out of the system.

Thanks guys, I will check the belt, double check the fluid level and if ok, run the bucket up and down to max a  few times and see if that helps.

Last Sat I had it out on the back property (woods) and got stuck a few times, had to use the bucket to help get unstuck. seemed to work good then.  I'm going to need it to move gravel around in a little bit.
