Rolled my EX3200 and need help

[Car Doc]

I will mention this again I will stake my reputation the crank being bent also! I believe you could at least check it with the head and the one rod/piston out by turning the crank and watching either the ring gear or the balancer for radial and lateral runout with a dial indicator not going to be easy to set up but now is the time to check it!

The ring gear edge of the flywheel is farthest out from CL so will obviously show a greater deviation than the balancer and also probably easier to set up a dial with either the starter out or maybe there is a side inspection plate like mine has.

I believe you may "feel" the bend also when turning it. good luck

When I said I have seen cranks so bent you could feel it in the clutch pedal I was serious. it doesn't take much lateral runout to wobble the flywheel pretty bad and generally cause engine vibration. I hope its not but good luck on it!

Hello all. Car Doc made a good call to confirm the crank condition while everything was accessible. I rotated the engine by hand several times with a dial indicator on the harmonic balance and another on the flywheel hub. Expected to see several "bumps" due to normal inconsistancy of paint and metal. However, I was very happy to see that the front only varied ".002" and the rear .0015". The cranks spins very freely with very little pressure required to start the spin and no areas of resistance during a rotation. I was only able to put a tiny "wiggle" dial indicator on a small portion of the main crank journal and it showed less than ".0005" movement. I have also inspected the rod bearings from the removed piston and there is no visible wear. The cylinder wall is in excellent condition without any signs of piston skirt contact. I originally ran the motor for almost 3 hours after the rollover (having hoped early on that there was only oil in the exhaust) and never felt any change in the clutch pedal.
Tonight I will pick up the new parts and begin reassembly. I will let all know the end result. Thanks again for everyones help!

Even with a fully charged battery (I have to put mine on a charger every other month or so beings I work a 21/21 day rotation and don't run it some weeks home), mine won't turn over with out the decompression lever down. Kind of a weak starter setup, but I'll never have bent valves from it being too stout.

My tractor will sit for months and start fine, well i guess i always use the decomp lever? Now that i said that in the next few weeks when i go to the farm i will ahve a dead battery in the tractor that i will have to jump! :laughing: Seems like everything with a battery is going bad this year!

Clemsfor. Batts, have a very finite life. My boat batts, are at the 10 year mark right now. Yep replacing them will be a pain in the wallet. 8 golf cart batts, and I have a computerized charger and never taken them down below 50 percent. They just die, so time to get a new one.

Im thinking i need to get a battery for my truck its been weak for a year or so. It wouldnt crank e weeks ago and it was cause of corrosion, cleaned the terminals and good to go till last night and it wouldnt crank, got a jump at the gas station and when i got home 30 mins later it did. The connection is bad casue the acid that coming out the battery!

Hi all. A quick update on the EX3200. Installed the new connecting rod and reassembled the engine on Friday night. Saturday morning I was SAFELY moving dirt again. Here are 3 pictures to show the smoking tractor, the #2 exhaust port and the bent connecting rod. Thanks to all for your help!
