Yeah that's definitely my next step. Currently brushing up on the service manual and trying to plan to remove the head. Either that, or I found a super low hour D1105-T for a good price so I could always just swap that in

Dang it man I'm sorry to hear, yeah definitely sounds like the route I'm going down. I found a d1105-T with around 200hr for $1500 and I'm very tempted to just grab that and drop it in for the couple extra horsepower but still entertaining trying to rebuild this one. It does have 2500hr though...

Just an update to the thread, I believe I got my valves adjusted properly, manual specs .007, lowest i had was .008 so i got it there and then gave it the slightest turn then tightened. Added my truck battery in parallel and she's definitely cranking faster/harder but still acting the same. Very...

Another great write up with great advice. I really appreciate it, I'm about to head out there now and try to start checking a few things. Definitely will keep the thread updated

Is there any possibility that could be due to valves needing to be adjusted? When I had the valve cover off and cranked it to make sure all rockers were moving, I was getting puffs of smoke around the rods as the motor turned over.

Awesome I really appreciate that write up! Definitely made the procedure easier to digest. I'm getting ready to head out there and get started on the troubleshooting for today. I'll definitely keep the thread posted if I make any meaningful progress haha

I did not, I'll be honest this is the first diesel I've tried working on and it's been a heck of a learning curve. The first time I tried reading the procedure I got confused because I think you're right that it's supposed to overlap a little and that threw me off. I'm going to reread that...

Yeah that's a very good point. Mine does the same where it's basically double duty when starting. My battery is dropping to right at 10v during cranking, which the manual says 9.7v and up is considered acceptable but im going to add my truck battery in parallel to see if it helps

You're right, I forgot to mention I have tried that once or twice. I will remove the small wire from the starter so I can turn the key to the start position, then after 10-15 sec I'll use my power probe to supply the starter 12v control to get it spinning. Seems like it makes a little difference...

Yeah definitely my biggest concern there. It's also, atleast according to the hour meter, a high hour machine so it's probably due for a rebuild. I'm just waiting for the adapter for my compression test kit to get delivered at this point, trying to see if I missed anything stupid along the way.

Yeah I'm hoping for the best but expecting the worst. So when I first got the engine freed up I didn't have a starter delivered yet so I did crank by hand to get all the liquid out of the cylinders, I also had glow plugs and injectors pulled so it had plenty of room to get the liquids out so Im...

Gosh I wish it had a decompression knob but I didn't see anything in the service manual for this model. As for the glow plugs, sadly it has a glow plug controller that only runs them for 7 sec, then reactivates while cranking. I'm not technically using a battery rated for cranking an engine so...

Yeah you definitely might be right, still waiting on that stupid m8 adapter to get delivered since the kit I got only goes to m10 glow plugs for testing. And I have a Groundsmaster 7200, she's got pretty high hours so it could be time for a rebuild, I did pull the valve cover and all...

Here's a video of the engine cranking over. https://youtube.com/shorts/XoOcN1ufjQE?si=8p3sTMwOtkDUrcKG I usually will kick the key to the first position which lights the glow plugs for like 7 sec, then it also re-engages the plugs the whole time the keys turned to "cranking" so they will be on...

Hey everyone, I have an older Toro Groundsmaster with a Kubota D1105 engine that I can't get to start. I've made a lot of progress and feel like I'm so close but just won't catch. I received this mower in a trade, the guy claimed he got it from an apartment complex that upgraded after the...

Oh and to answer your other question, if I keep the key turned, it'll crank the motor all day, but as soon as I let go and try to crank again, if it lands in the wrong spot, it will just click.

Thank you all for getting back, finally had a chance to dive in today and here's what I found. So electrically, everything is solid. Had some brand new 2/0 welding cable I used for testing/bypassing everything. Main lug voltage @ starter is only dropping like a half volt. Upon further testing, I...

Thank you both for getting back, I'll definitely reach out to the seller to see about warranty. I'm assuming the starter must not have been rebuilt right, or has a flat spot somewhere, that'd explain why it works one minute, but not the next.

Thanks for the reply, but trust me I've tried, I've gone as far as running a fresh power and ground straight off the battery, then using my power probe as the 12v signal bypassing ignition. Sometimes it will work if i hit the starter a few times with a wrench but I usually have to fully remove...

Hey all, long time reader, first time poster. I recently picked up a Toro groundsmaster 7200, has a Kubota d1105. It has a litany of issues I'm chasing so I'm sure I'll be asking more, but here's my current problem. The motor was missing the starter when I picked it up, I ordered a new starter...
