I don't believe new ones are available, if they were I'm sure they'd be a ridiculous amount of money. If you do change the bolster (I would in your case) it gives you a great opportunity to check/fix things, like the front seal on the engine and seals in the steering assembly. ...which by the way is a slippery slope, once you start "fixing things" where do you stop???? :lol: I ended up rebuilding the engine "while it was apart"! ...and I should/could have kept going. Going from front to back I chose to stop at the rear main bearing. Maybe this winter I'll start at the back and go forward ...or maybe not! :D

Hello,

I cleaned off the surface of the front casting and found some more troubling signs:

1. The front surface where the radiator bolts on has a pretty good wrinkle in it. As I mentioned, it was welded in the past and it's probably done.
2. On that front surface, I noticed a faint line that appears to be another crack
3. On the inside of the casting, where bosses are cast in place for the blind tapped holes for the radiator flange, one boss has one side that has cracked away leaving a path past the threads. This is where I think the leak started showing.

So it looks like I'll need another front casting and I'm probably going to replace the radiator as well. So here are my questions:

1. What's the best way to support the tractor while removing the front casting? It looks like the front end is supported by the underside below the steering gear. I'm assuming I probably need to bolt to the bosses on the side of the engine rather than place blocks under the oil pan.
2. Since I'll be pulling the steering gear apart, what seals and other items will I need?
3. Is the front crank seal pretty much a pull and replace job?
4. As far as sourcing a new casting, I see Steiner has one but it's around $360. Are there other sources? I'm in the Atlanta area. What's a decent price on a front casting?
5. Any other tips or tricks?

I'll be looking through my PDF manuals as well, but it's always good to ask before tearing into something.

Thanks again,

Kyle

1. You can support the front of the tractor with either blocks under the engine, have the engine supported from overhead (sling load), or by bolting braces into the torque tube. Any way you go, use caution!
2. There is a seal on the bottom of the gear box, a seal where the shaft comes in, and two gaskets. Replace them now if you have oil leak issues. There are also 4 bushings in there. So if you have slop/play in the steering, check them out as well.
3. The front seal isn't really a "pull and replace" job. It isn't too bad, but special tools and considerations need to be taken before jumping into this one.
4. Place a want add on the forum. You'll get a few hits, if someone doesn't contact you first.
5. Since you have to pull the hood, drain the fuel first. Have a couple saw-horses handy to set it on. Replace the governor spring while things are open and easier to get to. Oil the fan housing.

Check out the "how-to" section for threads on topics you've asked about here. Many good ideas and tips can be found there!

Just to clarify, you do not need to pull the crank pulley to replace the bolster.

you do not to take the front pulley off

But if the front seal leaks it is the perfect to take care of it. Otherwise, definitely leave it alone.

Hello,

Thanks for all the responses. My main concern when pulling the bolster is safety and properly supporting the tractor while the bolster is off. Since the rear wheels will still be on, I shouldn't have the issues that are shown in the picture with the tractor tipping - pretty scary. I'll probably build some type of support cribbing to hold the front end up. The tractor is in a pole barn type building with doubled 2 x 10 rim joists so I'll probably use a strap as well just in case. I think I'll leave the crank seal alone. If it leaks at all, it's very slight. I'll check out the wanted section for a bolster and see what comes up.

You could surely use the 2x10's provided there isn't too much load on them already. Splitting stands might be an idea/option. Here are a few possibilities:

Hello,

I welded up a jacking bracket to lift the Cub so I can remove the front end. I've got the two ends of the tube sticking out so I can place my jack stands under it once it's jacked up. I just need to get some more boards since it's on gravel.

Shoot, he sent me a message and I missed it. Well, I picked up one of the ones from Steiner, so it looks like I'll be a test subject. I'll keep you updated on how it goes. Will I need an impact wrench to get the original bolts off? Also, how much torque is used when reinstalling them?

I also picked up a new radiator and gasket along with gaskets and seals for the steering box. I can tell you that the Steiner casting already has a bronze bearing installed for the steering gear shaft.

I did some checking in the specifications PDF file and it looks like the torque is 150-170 ft-lbs. Is that correct?

Thanks,

I don't think so .. that is way too much. More like 35 ft lbs.
