Cub with Hydraulic oil in the motor

[69ranger]

Hello,

another Cub question..

So I am familiar with failed seals in the Hydraulic pump failing and letting oil into the engine. I know of a cub with this, problem, and possibly other issues caused from this failure.
Currently the engine is way over full, and there is a knock coming from inside, that sounds like a rod or other bearing knock.

The tractor does not belong to me, but a friend. So the question is... If the oil was drained and replaced and the seals fixed what are the odds that there is no permanent damage to the bearings? I think I know the answer, having worked on lots of engines in my life..
How durable are these cranks? Could a person roll in some new bearings and check clearances? Or would the crank likely be ruined?

Also what other parts in the upper end may have been damaged? I have a good crank, that could be used, but of course we are looking at the easy way out.
I am not sure if it has to have a crank, if the work to fix will be worth it, and the tractor may just get parted out? I hate to see that, but some die, so others can live on. If it goes this way, what are parts cubs worth?
I know a lot depends on the condition of the Front Bolster, other cast iron parts, and other considerations. Just a ball park figure, if you can?
It seems to me, that cubs in my area are getting harder to find, and higher in cost? Any one else think that this is the case? What are prices in your area like? I'm in Kansas..

$400-, ball park figure for a parts tractor. That's just for the tractor. Attachments/implements will add to the price.

Someone will have to disassemble and measure the engine to determine repairs.

I think that I am going to pull the crank out of the broken motor block that Dad has, and check it for roundness, and see if its usable. I need to do that anyway, so no loss.
If the crank that we have, is good, and the rest of the tractor is in decent shape, we may swap it out, as a winter project, and save it from death.
Lots or work, but not a lot of money to fix it, if new rod and mains would get it going.
The tractor has got a 42 inch mower on it, as most of the ones that show up around here do, so not much value there.

I think in Dad's stuff, there are at least 2 and maybe 3 woods 42's in the back of the shed, that he had no use for. As Dad got older, he bought cubs to keep implements that he used all the time on, and just swapped the battery from one to another. Sickle mower on one, disk plow, cultivator, and blade on the others. He has 5 total, but never got the last one in usable condition before his health failed him. All of them are just sitting now, in his shop waiting for some one to give them attention. For some reason Dad never warmed up to the 42 inch mower.
I think they are kind of hard on the PTO, if used harshly, but I use mine all the time.

A lot of thin hydraulic oil mixed in won't help evaluate what you have. I would start by doing an oil change then see how it runs and what the oil pressure looks like. Three quarts of oil is a pretty small investment to get a better picture before going down the path you are on now.

I would use the tractor for parts. Also, I would borrow Dad's Cubs and implements.

I will see what I can talk the owner into. The tractor is not really my deal, as I am just helping with it thus far.
Sometime I may get a chance at it, if it proves to be too much, and was why I was looking for a rough value. I hope it dont come up for adoption before I get the cash set aside for it. That may take a little bit..
Dad's tractor stuff is sitting and has been for about 4 or 5 years. Dad has Dementia, and it makes him mad if anyone messes with his things.
After he passes, hi stuff will be up for grabs.
He and if fixed up a couple of these together, and I will probably take one of them. Maybe a few pieces of equipment as well.
I will probably addopt the Red 64 model that he and i restored together. He has a pretty good yellow 75 model that the motor is pretty worn in. Might over haul that one an keep it if my siblings dont want it. I am about the only one who cares about old tractors, so there wont be much competition.

I will keep you all posted as to the cub with the knock turns out.
