Engine Work - Update

[ricky racer]

I've re-bored Cub engines that measured better than yours. Of course what you do is up to you. I would have an engine shop inspect your crank and offer suggestions.
Myself, I don't think you'll ever regret the money spent on doing a proper rebuild once it's done. I know I haven't, even though money was tight at the time. If the rest of the tractor is good and worth saving, it's probably worth doing a complete rebuild. You're fortunate that you have the skills to do a good job and will only need to pay up for the parts and machining.
Shop around for costs at area engine shops. I found a big spread regarding quoted costs. I made a post "Cost of Engine Rebuild " last year. I'm on my phone and can't copy a link to the post. It might help you decide if it's what you want to do.

a valve kit is to cheap not to replace the valves and guides, around $125 for it, has guides,locks and valves

tst, Eugene, and Ricky: I appreciate your advice. Will start searching for an engine shop this week.

As a side, I’m a little disappointed in the shop that “rebuilt” this engine in 2009. Had they done a proper job, I wouldn’t be faced with this now. This was my first tractor back then, but even as a novice, I remember not feeling great about the way they did things. BTW, they’re no longer in business.

Thanks again. Will let you know what happens…

Yea it clearly was done wrong it it had engine work back in 2009. You probably don't even put that many hours a year on it. That's terrible to only get that many years out of a rebuild. That said unless it was in something worked hard and many hours a day or week.

Not wanting to hijack Stanton's thread but what is the consonance on hardened valve seats? Oil pump,cam and lifters? Are new ones available or do you have to reuse?

[tst]

valves seats are available, they were part of the block, so the old ones milled out and new ones are pressed in

I share those thoughts as well. No, very, very few hours a year. If that shop treated other engines the way they did mine, then I can see why they're no longer in business.

That's why I like to do my own engine assembly. I have to pay someone do the machining but I double check every thing and take my time assembling the engine making sure everything is correct and within spec. Well, that and I'm cheap and don't want to pay someone to do something I can do....

I don't like to pay someone to do something that I can do as well.

That was what the owner of the machine shop advised me. "Time is money," he said. "Anything you can remove from the block will be saving you money."

Delivered the block, crank, cam, valves, and pistons to the machine shop yesterday. The owner has a '58 Cub, so he's familiar with them; also remembered me from last time when I had him deck my head on the AV. Nice guy.

Will let ya'll know what happens.

You're very lucky, Stanton, to have a good shop near you...and especially fortunate that the guy knows the Cubs! It makes a difference.

True, but still expecting this to cost an arm and a leg. We’ll see. Said he was several weeks behind; a lot of work to do.

In the meantime, I need to remove the posthole digger from the ‘48 and put the plow on.

[Eugene]

6 to 8 percent annual inflation. What every the cost, it will appear to be very cheap in a couple of years.

Good attitude Eugene!!

Yup. Invest in tractors or other tangible property. Money siting in the bank is worth less and less every day.
