400 gasser cranking problem

Anonymous-0 · Mar 25, 2012

I bought a 400 gas a couple of weeks from an Aumann on line auction, first time I ever bought a tractor sight unseen. When I picked the tractor up it would not start and it appeared that it may have a had a ground problem. After getting it home and wking on it I found burnt wires, no problem I just rewired it, had the GEN & starter tested (they were both wking correctly). Went to start it today and the same problem, turn the key and the starter would stall. Recked ever thing, cked good. Don't know why but I pulled the T/A to the low side tried it again & tractor started right UP, never ran into this kind of problem before. Anyone got any ideas what problems I have ?????? Note: Aumann folks pulled off the the tractor at the auction sight, I drove it before loading it, tractor ran ok, T/A wked as it should,no slipage, no unusal noises all running cks were good.

Is it 6 or 12 volt? I'm guessing 6 b/c of the genny being on it. Did your wires from the battery to the starter post then to the starter get hot? They need to be 00 gauge cable. Well a little smaller is ok. Also check that the starter has clean contact where it mounts. No rust or paint. Or if you can mount the ground wire from the battery to the starter post and see if that helps. If its burning the wiring to the lights and other wires I hope others will chime in. I'm not an expert but thats a place to start.

It has a 12 volt system > gen was converted to 12 volt + grd. I always use welding cable for the battery cables & solder the terminal clamps. Voltage is good on all circuits the only thing not making sense is the starter stalls with the T/A in direct (forward).
Thanks for the reply

You indicated that the TA worked normally when you drove it. Maybe the engine has enough power to overcome a locked TA but starter does not. I have seen a TA lock in low side but when you threw the lever ahead to direct drive it basically stalled the engine if you would not pull lever back again. Take the little cover off top of TA and with clutch pedal pushed in see if you can move the carrier in normal direction of rotation. It should move freely,only one direction though.

My take is that the tractor was on a slight hill trying to roll backwards a tiny amount. With the TA ahead, (and the TA a bit out of adjuastment, or the clutch not down all the way (or some such combination) the act of pulling the TA back moved the engine just a little. Starters jam in the flywheel and engine rotation frees them. Whne it locked up I bet the starter would not even budge the engine. If so, it needs a new style starter drive (no big spring) and the teeth of the Ring gear looked at. If it does it again, the premium test is to loosen the 3 bolts on the starter to see if it unsticks with a hearty click. Jim

It this "pull TA, tractor starts" thing REPEATABLE?

As in, it will ALWAYS start with the TA back, and NEVER start with the TA ahead?

Or was it just a one-time thing?

Well guys found the problem >> The Farmall angel must have been on my shoulder. Something told me to watch the fan. Engine was turning backwards. Has the wrong starter. Sorry about the post I meant to say the engine would turn over on the low side of the T/A, it never started.
Thanks for the replies
