WD starting problem

My boy and I were working on his 49 WD getting it piped for 2 way hydrols. When he was done with that, he tried to start it with the starter. No go. Tried different batts, no go. Hoked the cables up to the pk batt. No go. Tok the starter out and laid it on the fot board. Hooked the vables up again and it turned over.

Today, I tried it al again. No go. Sprayed the starter after taking it out and the surrounding ring in the tractor with carb cleaner, then wiped both off. Sprayed locking bo0lt. Put it together and tried to start it. No go. Noticed the batt cables were bad, especially the neg cable. Hooked the pk jumper cables to it, the neg on the frame, the pos onto the brass bolt on the starter. No go. Hooked the neg to the molding on the back of the starter. No go,.

Whats next?
 
I like to start mine using the hand crank, just for fun. Three quarter turns and she fires right off, if I have remembered to turn the gas on. Just one notch on the throttle and choke only on the coolest day.

But, are you saying that yours will not turn over with the starter? If so, then remember to lock the foot clutch forward to take the hydraulic pump and wet clutch out of play. There is a lever to lock foot clutch out.

Can you roll engine over with hand crank?
 
Just because it spins off the tractor does not mean it has the power to spin the engine over. Good chance the starter is on it way out but the only way to be sure is have it checked by an auto part store or other such place to see if it is drawing to many amps
 
I know u probably checked it but make sure u have a very clean and good ground?? Thats seems to be the main issue when your problem occurs
 
Got it started. The NEW NAPA battery the boy got was positive ground. Changed it around and it started fine. OH and I also put better cables on the battery.
 
It's a common problem. That's why I like hand crankin. Once you learn which way to pull, you never have to worry about it again.
Glad that you got your mag problem figured out.
 
6 volt or 12 volt??? If 6 volt is came new + ground. If 12 volt and has an alternator on it bet he smoked the alternator
 
are you saying the new battery was charged backwards from what was marked on the plastic case?

batteries are not listed as positive or negative ground.

ground is determined by what post of the battery is common to the chassis
 

Some people even believe that a starter rotates in the same direction whether +ve or -ve ground, 6V or 12V. Where do such ideas come from?
 
can't make general statement on starter rotation and ground polarity unless you know about the field.

series fields menas the starter will turn same direction, no matter what ground.

voltage potential 6v or 12v, just means a 6v starter turns faster.

then you get to the permanent field motors.. IE.. magnets. those motors will reverse with reverse polarity
 
EVERY starter I have EVER worked with spin the same way weather positive or negative ground. That is why it is so easy to switch them to 12 volts and negative ground for an alternator
