45 2N Plunger that connects to the Control Arm Yoke is Bent

allenlane · Dec 4, 2017

Can't really tell from my shop manual how difficult it is to take out that plunger rod inside the control spring. Has anyone ever straightened one? Are they easy to bend in the first place?

If the plunger inside the draft control spring is bent you will, no doubt, find considerable damage to the mechanism inside.

Uh Oh - How do you bend one? I would think you would have to back into to something(compression) pretty hard to bend it. Doesn't appear you could bend it by pulling on it (tension).

hink about it.....if you were plowing an hit a rock, that will be compression on the top link.

The most common scenario is driving into a significant depression, e.g., ditch, gulley, etc. with a lengthy implement, e.g., rotary cutter, disc, etc., connected to the three point with a rigid top link. When the trailing part of the implement contacts the ground, the rigid top link compresses the spring. Enough force will damage internal components.

Removing the yoke will be the most difficult part due to fine, rusty threads. Heat yoke with a rosebud to break the rust bond. Don't crank too hard on the yoke or you will mangle the connector link.

You could straighten the plunger but as Dean pointed out, their is likely more carnage inside the lift cover. Used, original lift parts are plentiful. Tear it down to see what you will need before shopping for parts.

With the introduction of new parts, a lift realignment will be prudent.

Are there any other problems you need to address while you have the lift off?

Bill called it. Getting the yoke off was tough. I really don't want to take the lift cover off now if I can avoid it. It appears that I can reach the bent section of the plunger with a rose bud without taking the cover off to straighten it. At most I'll be doing some mowing, no plowing so don't really need the draft control. What is the worse thing that can happen if I try to straighten the plunger with heat without taking the cover off?

Give it a try and keep your fingers crossed that nothing broke off and fell down into differential or PTO shaft.

Don't heat the plunger more than enough to straighten it and don't quench. Let it cool with ambient temperature.

Very easy to straighten the yoke with a torch. Was able to pull it out enough so torch flame was never inside the housing.

Glad it worked out for you - How does the lift respond?

Well good news and bad news. Good news is lift raises fine, but it will not lower. Is it supposed to lower without any weight on it?

Bad news is that I'm guessing while that plunger yoke plate was loose, water got into the hydraulic system. I pulled out the Hydraulic dip stick before picked it up, and only saw hydraulic fluid. Also guessing the tractor had set for so long that the oil was sitting on top of the water. Now that I've been running the tractor the pump has mixed it all up.....now looks like mustard ! Not good.

What is the best way to get all the water out of the system? I'm draining it but doubt I'll get it all.
