Not sure what the end game is for this but it's too good to let go. It's got some issues but is largely original. I'm going to start with a gearbox for axle issues and penetrol treatment to preserve the patina...

Good looking original there.  Definitely worth the effort of saving.  

Some touch ups here & there and you'd have a great rig.

Agreed 100%

Lots going on today other than tractors but I'll get some of it done...

[ineedanother 2,175]

The drain plug is stripped so no draining the ATF but I did manage to get the good hub off and that axle looks fine. 

[ineedanother 2,175]

I forgot I could drain the case from the bottom of the motor, 3 quarts of clean ATF. Pulled the pump and motor to make it more manageable from a weight perspective. Found a nice comfy nest of insulation and nuts in with the controls. Got the gear box off and will get the frame cleaned up but everything looks good and solid. I would really like to have a roller again today but my old self is close to done getting up and down off this floor.

[ineedanother 2,175]

Well, it's a roller. I really could have had it all back together today but too many other distractions and no ATF on the shelf either. Tomorrow's another day...

[ineedanother 2,175]

I have power. Converting over to 10-30 so need to drain the lift cylinder and have a list of other things to address but this was a big line item 

[ineedanother 2,175]

Needs a good bit of attention elsewhere, to be expected being a '73 with no records and not much known about its history. Someone has been pumping grease into it but the fuel pump leaks, most of the wiring is original, I can't tell yet if the head has ever been pulled and doubt that the valves are in adjustment by the way it runs...stuff to do  I'd like to pull the balance gears but I've got other priorities and no tasks in mind for this one. We'll see how things shake out, it might be worth a couple hours to go ahead and do that while I'm this far in.

Eliminating or replacing the grenade gears will be a mandatory maintenance procedure here from now on. Period.

I don't have a K341 to comment on, but on my Bronco's K321 (same crank), the increase in vibration was not nearly as bad as I feared it would be. It's definitely there, but knowing my engine is now safe from window making is easily worth it. 

 

I won't install another Kohler with the balance gears still in there. I like these old engines too much to take the chance.

I've read a lot of threads regarding the balance gears and have never seen anything related to data about engine wear or other justification for them. If main bearing wear or something else significant is impacted one way or another I might have more of an opinion but I can't see how a bit of vibration at some engine speeds would be worth the risk of "venting the block" as it has been so eloquently put. I'm definitely leaning toward removing them from all of mine.

My understanding is: 

The balance gears were engineered back in the 60s to quell vibrations at upper end RPMs. 

 

On the engine I personally removed the gears from, the vibration above 3400 RPM is too much for the BATTERY. 

I just kept the top at 3300. 

Yes - I do understand that the Sundstrand is rated for 3600. 

 

It doesn't mow, snow blow, or run any other implements, and I don't tax/work/stress the engine much by plowing snow. 

My experience and research shows me that the way I'm operating this machine is just fine. 

 

Modify YOUR machine at YOUR discretion. 

ALL of mine will be gear deleted.

I've had issues in the past with the #3 phillips for the screen on the flywheel. I've soaked these for a few days and hit them with the manual impact. Four for 4

Niiiiice. 

 

That manual impact driver was a recommended purchase by the folks here on Redsquare several years ago when we restored my 1974 C160-8 Cinnamon Horse. 

EXCELLENT purchase.  

Whack! To tighten. Then loosen. 

Repeat. Remove.

And they're cheap...although the phillips tend to be stronger on the better ones. Great for 3/8" sockets but the phillips driver tips on these are priceless IMO.
