bent front bar on Jinma 204

You can use a tool called a Pickle Fork or Ball Joint Splitter but if there is a rubber boot be careful not to damage. You can also just put the nut back on half way or so and then use a piece of hard wood like oak and place it on the nut to protect and give it a wack with a hammer. Be careful not to damage anything. This should loosen it up then remove the nut and it will fall out.

That worked got it off - was able to straighten some - but not completely - think it would need heat to allow that - was able to get to the point to slowly get it back into it's house - big red doesn't like being outside. The rod and the ball joints look pretty rough - my guess is that I have whacked it before and the snow finished it, so will order new parts and throw them on.
Thanks everyone for all your help - parts source?
Cheers

You know, I had the exact same thing happen to me snow plowing on Tuesday evening. the rod was bent back in a nice even arc and the front wheels were pointed outward.

I straightened mine in place using the little bottle shaped screw jack that comes standard in all the 80's-early 90's toyota pickups. I put the base of the jack against the crossmember for the FEL subframe, and the slight curve in the top of the jack matched and held the rod nearly perfectly. I used a small scrap of 3/4" plywood above the rod and below the front dif structure to keep the rod moving forward perpendicular to the ground and not up into the driveshaft cover. I had to go a little past center to get it to stay straight, but it straightened up pretty nicely, and only took me about 10 minutes on the garage floor getting rained on my melting snow I have bent it before on a stump and straightened it in a similar manner. It now probably needs to come off and be replaced.

The ball joints can be a real pain. Be carefull using the hammer on the end on the castle nut, as ALL the hammer force is borne by that cast iron arm in shear(weakest mode) untill the ball joint pops free. The pickle fork is the prefered method as any hammer force applied to the fork can be directed along the length of the cast iron arm in compression which is a stronger axis. The hammer blows will also force the two pieces apart equally like a splitting wedge on a piece of firewood. I don't think I have ever used one that I didn't damage the boot though. I have also had pretty good luck using a small puller applied to a well greased center punch mark right in the middle of the threaded end. I do this with the castle nut loosley in place so it can chase the threads if the screw rod should slip or distort the end of the threaded rod. Once it pops, you unscrew the castle nut and they usually lift right out by hand.

Good luck

It sounds to like the rod may need a little beefing up. A piece of angle could be welded lengthwise to the front or back side to strengthen it against future snow plowing jobs.

I would be leary of beefing it up too much. You get it too strong and something else will break. I would much rather straiten the bar then replace a broken steering knuckle or steering cylinder.

Maybe a guard is in order. I use my tractor in the woods about 75 hours a year logging and have done no damage. I guess I am just lucky.

I sent off an order to affordable - hopefully they have the rod and joints in stock. I checked later and must have nicked one of the threads - so the nut doesn't want to go on. They had enough play in them that I thought I may as well as replace them at this point.
Appreciate the ideas on taking the curve out - I measured the angle and it was 41 degrees so lots of bend.
I like the idea of a guard - I think beefing it up though would cause damage to other parts - I do think I will put a bar inside for a little bit of added power.
As always all of you are great, and made my day a whole lot easier.
Thanks

The first time I bent mine, I was brushhogging. I use the FEL bucket down low as a feeler in the thick brush. I had lifted the FEL up a little to push some big branches out of the way and didn't put it as far back down and a short stump snuck under that was just high enough to catch the tie rod. I was thinking the same thing about a guard, somehow attached to the bottom of the front axle to protect that rod.

I am still not quite sure how I bent it pushing snow. I didn't hit anything as I was in driveways the whole time... I don't think I hung the right wheel up against anything, but I guess it would be possible to bow an already slightly bent/out of true rod with the steering hydraulic cylinder? Left wheel turns, right wheel dosn't, tie-rod bends under compression?

John,we do have all the parts in stock and they will ship out on Monday,please call Jerry at the shop 979-865-4002 to confirm the length of your tie rod,some of the 20-22 hp tractors used a shorter tie rod..Thanks for the business

lol ... I can't believe it.
All you guys who bent your tie rods and I've never bent mine.
Of all the things I've screwed up on my tractor, you'd think the tie rod would be #1. It's obvious I'm much more careful than you guys after all. Now I have broken the tie rod ENDS off before ... 2 times.

They've got Jinmas Rob. I bent the same **** rod within weeks of owning my first Jinma. But our tractors are much less susceptible to this particular issue. I've never struck - much less bent - the steering rods on either of my current tractors. It's the high placement and the front diff housing that protect our pull rods.
