OhioGuy89 4 #1 Posted January 16, 2015 Hi folks, so I was trying to start my 520-H earlier, and it makes a whirring noise when I turn the key to start it. Sort of like a vacuum. I've got a video of the sound and I'll see if that works. If not let me know so I can post it somehow.https://vimeo.com/117007795 Share this post Link to post Share on other sites
stevasaurus 23,274 #2 Posted January 16, 2015 Sounds like the starter Bendix to me. It is first turning and then extends against the flywheel with out engaging. 2 Share this post Link to post Share on other sites

Dirtdog524 61 #4 Posted January 16, 2015 I believe it is time for a new bendix or starter Share this post Link to post Share on other sites
stevasaurus 23,274 #5 Posted January 16, 2015 (edited) The shaft the Bendix spins on could be dirty. You can pull the starter, spray the shaft with brake cleaner and lube (I think) with dry lube...graphite. Some NAPA's used to be able to check your starter and/or send it out to be fixed.

OhioGuy89 4 #6 Posted January 16, 2015 Ugh. Oh boy. Does replacing the starter mean taking evrrythhjg apart again to get to it? I just finished piecing it all up. Boo. Share this post Link to post Share on other sites
Tristan Wilson 117 #7 Posted January 16, 2015 sounds like a dirty bendix or a week battery my onan on my welder does that when the battery gets low Share this post Link to post Share on other sites
stevasaurus 23,274 #8 Posted January 16, 2015 (edited) Well, that is a little different....maybe. Did the tractor start before you tore it apart?? Did you have the starter off the engine?? It could be a low battery (check that first), it could be a shim under the starter to line it up better...if one was there before, could be a bad ground keeping the starter from getting all the juice it needs. Check battery and grounds first...then you will have to pull the starter. it did sound weak in your video. If you do a search in "Engines" and in the "Electric" sections...type in "starters" a number of topics come up...some of them for the 520H.

OhioGuy89 4 #9 Posted January 16, 2015 It started befoe I tore it apart, no problem. I'm gonna charge the battery again and hope that's it Share this post Link to post Share on other sites
boovuc 1,090 #10 Posted January 17, 2015 If it isn't a battery issue, the starter comes off without tearing "everything" apart. Pretty easy in fact! Share this post Link to post Share on other sites
Save Old Iron 1,571 #11 Posted January 17, 2015 Before you tear anything apart, measure the battery voltage AT THE BATTERY TERMINALS while cranking the engine. If the battery dips below 10 volts, strange things can happen at the starter. 1 Share this post Link to post Share on other sites
Save Old Iron 1,571 #12 Posted January 17, 2015 (edited) If the battery tests OK , measure the voltage drop from the positive battery lug to the power terminal of the starter.. Make the measurement while the starter is cranking. Good wiring will show very little voltage drop (less than 0.5 volts). Poor wiring will show several volts dropped and therefore slower cranking. You can perform the same measurement on the ground wire from the battery to the starter case. This process will allow you to tell if the poor connection is in the positive wiring or the negative ground wiring.

OhioGuy89 4 #13 Posted January 17, 2015 Just tested the voltage drop at the battery terminals while cranking. A very low drop, about 0.5 Share this post Link to post Share on other sites
KC9KAS 4,744 #14 Posted January 17, 2015 Just read a post on another forum...Guy got a GT that "needed work". He put the battery cables on CORRECTLY, and the thing fired right up......Are your battery cables connected + to solenoid and - to ground? Share this post Link to post Share on other sites
OhioGuy89 4 #15 Posted January 17, 2015 They should be, but I'll double check. I never touched the cables on the solenoid. Share this post Link to post Share on other sites
ericj 1,579 #16 Posted January 18, 2015 what was the voltage, check the voltage on the blue wire at the starter when cranking you need 12 + volts to get the starter to crank properly what year 520 is it, it does make a difference eric j Share this post Link to post Share on other sites
OhioGuy89 4 #17 Posted January 18, 2015 The voltage was around 14.3 I believe. The 520-H is a 1992 model. Here are some photos of the wiring to the starter. Everytting looks fine to me. What do you guys think? Share this post Link to post Share on other sites
OhioGuy89 4 #18 Posted January 25, 2015 Bump. How would I test the voltage on that blue wire? Do I have to remove it from the starter in order to get my multimeter clip on? Share this post Link to post Share on other sites
ericj 1,579 #19 Posted January 26, 2015 you can pull the blue wire and hook up your meter and try to start it and see what the voltage is. eric j Share this post Link to post Share on other sites
OhioGuy89 4 #20 Posted January 26, 2015 Ok. Good deal. So it would be the positive clip to the positive terminal on my battery, and the negative clip on to the end of the blue wire? Share this post Link to post Share on other sites
ericj 1,579 #21 Posted January 26, 2015 no negative battery wire to meter and positive lead from meter to blue wire eric j Share this post Link to post Share on other sites
OhioGuy89 4 #22 Posted January 26, 2015 Ok. So I just had it backwards. I'll check the voltage Share this post Link to post Share on other sites
OhioGuy89 4 #23 Posted February 21, 2015 So I got some bad news. Ii finally broke down and took the tractor to the local place that works on them. I just didn't have the time to get the work done, plus I've been a bit sick of getting stuck in my driveway with no way to plow. Turns out the con rods are broken. I'm not sure how it could have happened though... Share this post Link to post Share on other sites
JackC 617 #24 Posted February 21, 2015 Both connecting rods broken? Not likely. Maybe the guy want to buy your tractor cheap? Share this post Link to post Share on other sites
OhioGuy89 4 #25 Posted February 21, 2015 Maybe. Although I know they don't buy used equipment outright there. I mean, I did turn the flywheel the wrong way once to make sure things turned. Could that have broken something? Share this post Link to post Share on other sites
