Sullivan Hi-Tork starter

my starter is one year old and the one way is starting to slip. I have been putting tri flow on it. Thursday I was breaking in my new ys 91sr and it was not starting very well. the sullivan start wand (shaft and one way)was so hot you could not touch it. any suggestions

Call Sullivan.

Run it on 16v-18v instead of 12v

So if it's already slipping, how is increasing the voltage going to help?

I am using a 18V l-ion makita battery setup. voltage is not the problem. I did try two batteries yesterday. both with the same outcome.

Higher voltage for the over-heating
- - - less like to stall and pull excess current

Clean/replace the one-way for the slipping.

Loosen the glow plug,that will lower the compression and starter should be able to turn it. When it starts tighten it back up.

was so hot you could not touch

Not good, did the starter have a strong smell to it. If it did the starter is more then likely toast.

Damn that ground is hard!

Don't hold the start button that long! The starter should NEVER get that hot. A better battery will help.

If you are drawing from a typical hobby store gel-cell pack it probably can't deliver the current you are looking for. Go to the local discount store and get a lawn tractor battery or spend the money for a higher voltage setup. Also make sure you have low impedance connectors.

I don't have a 90 but I have started several with my Sullivan Dynatron. It boils down to how strong is the battery source for me. I tried starting a gasser (Zenoah G26) with my Dynatron hooked to my truck battery, no go. hooked up two basic gel-cell batteries for 24V and it spun the gasser like it was an OS-32.

...yep...

Looks like you need a better starter too then. I use a hobbico 180 starter and start g38's with it and a g-62 once it has been ran and warmed up. I just run 2 7.2 volt 1500 packs works fine. Now if everyone read what the OP said his one way bearing is getting hot not the starter. Clean the one way out and try it. if it still gets hot replace it.

Always amazing how many post away w/o even reading the thread.

I just installed a new sullivan shaft and one way.Guess what? It fixed the problem. Tuesday I will ship this one back to the manufacture.
thank

glad you got it sorted. I have found when a oneway starts to slip I clean it with some carb cleaner and let it dry good it will work again. But I have seen them no matter what not work right.

OK Ace Dude, I did read the OP. The part about the starter being so hot he couldn't touch it. That's where my response came from... perhaps YOU are the one that didn't read the thread.

Mutt - my post was to show that higher 'voltage' helps the starter turn over bigger engines. Your solution of a 180 with twelve cell power which is likely over 16V fully charged just adds to my point. Whether a Dynatron is a better starter vs the 180 is not the point, higher voltage make a BIG difference.

...yep...

I have said it before,
The only problem with 12V starters is that people run them on 12V.

You need to get over that initial start up torque and get the motor turning. 12V has a hard time doing that.

I use a TorqMaster-90 on my YS-91 with 16 cells CP1700
- - - works just fine - - - for years - - -

You still didnt not read what the OP said. You still do not understand what was asked.

and the one way is starting to slip

That is what was getting hot NOT the motor. so your idea of more voltage does not apply here. He needed a new one way bearing or clean out his old one not more voltage. For once I have to agree with acedude interesting concept.

Start shaft slipping?

Hi Stupineer;
Using Triflow seems like a contradiction, Oil for lube on the shaft when engine is spinning faster than the starter and teflon when you need grip?
Use ATF.

Starter shaft problem

I just got mine back from Sullivan, The problem was the oneway bearing was actualy slipping inside the body of the setup, not bearing slipping on the shaft. Needed to be pulled out and re glued in the starter wand. that fixed it
they said to go easy on the lube as it tends to cause the problem.
