192 Ford 4 cylinder in a Jubilee - A Risk or Reward?

[Mountain_a]

Hi all,

Let me just preface this by saying I know I may have screwed up, I impulsively buy and it’s an issue I need to fix!

That being said, the engine in my Ford Jubilee failed last year. Head gasket went and developed a crack in the block in a few places as well as cracks in the head. Not sure if it was by me in the past, it did overheat quite severely once when I first bought it, fixed the issue never happened again. But anyways I figured it’d be nice to upgrade the motor since my tractor struggles to bale especially when uphill, and who doesn’t like a little more power?

I figured since it’s my go to tractor, I’d like to get it working ASAP so I wasn’t picky with what I was going to be putting in, whatever it was going to be, I was going to rebuild it before full assembly and it needed to just go straight in the tractor with little to no adapting, so a 134, 172, 192, gas, diesel, etc,. I wound up buying a 192 industrial unit gas for $200. It wasn’t until after I found this could be a mistake.

A 172 already slightly risks damaging the rear of a Jubilee with the extra power upgrade, the 192 really hammers that home as it makes almost nearly double the power.

I’m not sure how many more times I’m going to be using heavy ground engaging implements with this tractor, plowing is going to be very rare but at most, only light cultivation and maybe discing as I’ve since transitioned to no-till. However I do plan to occasionally mow, ted, and bale. Bush hogging, pulling wagons, and occasional loader work is a definite.

Are there any potential upgrades I can do to the rear end and transmission of this tractor? It has a Sherman lo gear as well. I know I may be limited for upgrades but every little bit counts. This isn’t a tractor that gets used every day, I have a very small operation and maybe only a few acres with a couple tractors, maybe 75 hours a year at the very least.

I believe you are overthinking what problems you have. First off it is not clear if you have the 192 in the tractor. Second I'm not a Ford guy so I'm not familiar with any transmission problems that the Jubilee may have. So with all that said, I would go with the 192 and "baby" the tractor when using it in hard pulling operations, e.g. plowing or discing. The extra power should not affect the tranny or rear end when doing light duty tasks such as mowing, raking, etc. To my way of thinking you got a replacement engine at a reasonable price, and according to your post the tractor is capable of performing the tasks that you need done; therefore, I would use it as is. While upgrading the transmission/rear end may be possible, I would lean towards purchasing a bigger Ford or something like a Super 55 Oliver.

Its got the same rear end as every N made its rare to see a issue with those rear ends. Yes you can overpower it I think as long as you don't abuse it life will be good. On those tractors I am not a fan of big tires the tires need slippage big tires and weights counter that.

While it is true that the rear end of an 800 is much beefier than the jubilee, there will not be an ounce more stress on the Jube's rear end unless you go out and get bigger implements, or add a lot of extra weight to the rear to enable pulling heavier tools.

You'll have a tractor with an alligator mouth and mockingbird bird a - - but if you aren't hot rodding it all the time it'll be okay.
The rear axles on the NAAs were their weak point. Keep the big nut on the axles tight and don't over ballast the rear.

I too think if you keep the weight down and stay with normal tires so it can spin if needed then you can not abuse anything.

Mine has nearly twice the hp of your 192. It definitely isn't a daily worker, but, the only thing it does to the drive train with a 6' box blade full of gravel is spin the rear tires.
