Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hello, welcome to Just Answers. My name is XXXXX XXXXX I would like to help you with your question
There is often a stator as well as a regulator on this engine. Check the side of the engine block and see if there is a box with some wires going into it from the engine, and then back out to the wiring harness. (usually around the dipstick area) Check this and then get back to me with the number of wires and their colors and we can go about checking out your charging sytem
Well I cannot do right now.. Maybe tomorrow.. Will that work?
What am looking for?
that is fine. I should be on tomorrow at some point to check. I will find you a picture of it.. just a sec
is this on a mower with an electric clutch?
It is troy bilt garden tractor with a tiller in the back.. About a 1996 year
does the shaft come out underneath?
It dose have electric clutch for the tiller..yes on the shaft..
The picture is the same as the one I got,,
this is a common style here. the wires coming from the engine are from the stator. you should get over 28 volts of a/c current from those 2 wires.
the box is the regulator. if the regulator goes out, then it can stop charging as well.
I have tested the two black wires from stator, and no voltage!
oh ok.. I did not realize you already tested them.
The stator is located underneath the flywheel. You will need to pull the center grass shield offThen remove the shrouding on top
there are something like 6 or 8 bolts holding the shroud on. and you will have to take the fuel pump loose, shouldnt have to disconnect the fuel line though. there are a few under there as well.
Will have to pull the engine out of the unit to do the job? and should replace the stator and regulator at the same time? How much will this cost you think?
if the shaft comes out the bottom of the engine, then the flywheel and stator are on the top, so normally you do not need to pull the engine.
I can do one in about an hour, so that part depends on the mechanic and labor rate. stator and regulator together probly cost around $100
and I would likely replace both just to be on the safe side.
If you feel up to tackling the job I can go through the rest of it with you. It is not really that difficult, just time consuming, and you need a few common tools
yes, am planning to do the job, and I got all the tools..How do get back to you?
you can get back to me through this question. Would you like the rest of the procedure, or are you wanting to wait until you are doing it?
Yes, why don't you give me the procedure just case I cannot get hold of you.
ok no problem. the grass screen in the center, then the shroud around the top.
after you take the shroud off you can see the flywheel and the two ignition coils (one for each side)
sometimes you can to it without taking the coils off, but i normally take them loose just in case.
then you pop off the flywheel, it is held on by either a bolt or nut
taking the flywheel off is not hard, but there is a procedure. you take the bolt/nut loose, and then thread it back on about 1/3 of the way. take a pry bar and put it under the edge of the flywheel and the block, and while pulling up on the underside of the flywheel, hit the bolt/nut with a hammer. It should pop right up. **now when doing this you want to just get the outside edge of the flywheel with the bar, if you go in too far you will be pulling up against the stator and you dont want to do that.
this is a very good video of a guy taking a flywheel loose. its on a push mower, but the basic idea is the same. link
once you pull the flywhee, the stator is underneath. should have 4 bolts holding it to the block. look at the way the wires are run out the side and behind the starter, sometimes you have to loosen the starter to take the wires out and run the ones for the new stator.
A few tips when putting things back together, put a drop of locktite on the bolts for the new stator, and on the flywheel bolt as well. make sure and torque down the bolt for the flywheel, you want something around 60#'s. if you have an impact that should do it fineon the ignition coils, take an index card, or a business card and put it against the coil legs, bring the magnet around and let the coil go to the magnet with the card in between. then tighten the bolts for the coil. this will set the gap for you on the coils.
so is that it?Also do you have any knowledge on Bolens hydrostatic transmissions.. I have a leaking axle seal, and it looks like you have to disassemble the whole unit just to replace the seal..
that is the process for the stator. Not too bad a job.
Well thanks for your help..
have not hat much experiance on the bolens hydro unfortunately. I could try and find you a breakdown if you have the numbers from the machine, but would not be able to do so until monday..
I can get you part numbers for the charging system if you have the rest of the model info. may be handy to have.
I have a breakdown already, but hate the idea tearing the whole down just to replace the seal!!
yes, send me the part# XXXXX you have them.
The only one i have been into was on a craftsman, and I had to split it to replace the seals on the axles. there was a groove that the seal sat in, so it was the only way to do it.
ok part numbers.
the regulator should be 691185 ebay, and the stator should be 696458 ebay
the links should pull them right up on ebay. otherwise, most lawn mower shops should carry them
Are these new or used?
it will give you a list, on electrical I would not recommend used
So they are new?
it should specify. If you havent used ebay before, you can go to partstree.com. and just put those part numbers in the search box. I use them all the time and get good service, and the parts would be nes.
Well you have been a great help.. I will tear into it in the next few days..
Can print all this info up?
I think you can. I know it switches to a different format after you accept, and it should let you go back and pull our conversation back up.
are we done..
if you are satisfied with my help, then you can hit accept and it will finish it up. *If you need anything further, you should still be able to get back to me even after you accept the answer.
