You should have no trouble finding the needed parts. Several forum members offer used parts for sale, just post a wanted add on the VINE forum. Here's a link to Ken's guide "tool" for center drilling head bolts. http://farmallcub.com/phpBB2/viewtopic. ... 41&t=65687 If the link does not work, look for my recient post on "tips for removing siezed head bolts" for more information. Not a difficult repair, just time consuming. BTW, I would love to have a project like this but I suppose two is enough for now. Good Luck! Stan

Before you spend any money and before you drill out the broken head bolts.

Mic the crankshaft. See if it needs to be turned or polished.

Mic the cylinders and pistons for condition and fit.

Opinion. Cheaper to purchase a good solid running engine.
I have an excuse. CRS.

All the fasteners are listed in the parts book. Look up a part and the associated bolts and washers are specified in the text. Some fasteners, like head bolts, are special and you get a part number instead of a dimension. I buy grade 9 bolts from McMaster Carr for head bolts. 3/8"-16 x 3 1/4" for the long bolt and 3/8"-16 x 2 3/8" for the short bolt. I cut my bolts to the exact factory length if they are too long, otherwise threads protrude into the coolant.

Your local auto machine shop should be able to get all the engine parts you are missing.

I have a drill jig for drilling out broken head bolts. All you need is 2 threaded holes in each row to bolt it down. I used 1/2" shoulder bolts to attach to the block. There are also moveable hardened drill bushings that can fit in each hole that need to be drilled out. One is smaller and the other is .312 that is the tap drill for 3/8-16unc. Also there is a .375 bushing to guide the tap. Cutout in bar to clear the oil filter area. If you need it let me know. I will not be using it anymore. I made it on a mill so the center spacing are correct.

With help from this group of folks you can get it repaired and running they are very simple and rugged machines. Your hours of pleasure after it is running will far outweigh the pain of getting it back in shape. Ask for help and you will get expert comments, enjoy.

Holy cow, that's fantastic! Let me see what I have got for sure, and I may take you up on that! :thanx:

It's really neat that even hauling it home I got a lot of positive comments from people who saw it. I've got a little diesel Mitsubishi motored Satoh tractor I use for utility work around the house and nobody gives it a second look, but an old Lo-boy Cub gets people talking. I live in a rural area so tractors are all around me (house is surrounded by a bean and corn field).

Took a closer look at the motor this morning.

First, it looks like I have maybe only 6 broken head bolts and the rest are just full of mud dauber nests.
Second, the starter and generator are labeled 12-volts, so it has a 12V system already.
Third, it looks like the interior of the motor is pretty clean, no big piles of goop.


I have a question about the valves. I'm looking around and finding a complete valve kit for the motor. But they don't seem to show the retainers. I'm used to there being a valve spring, a cupped-washer looking retainer, and then the two c-shaped keepers that fit the groove in the valve shaft and lock into the retainer.

Where do I get a valve kit with retainers?

post a wanted ad in the Vine for the retainers. They also had valve rotators too, for the exhaust, if you don't go with hardened seats. Try Hamilton Bob, one of our sponsors.

Hamilton bob's kit doesn't seem to have the retainers either. Shouldn't there be a round cup-washer - the retainer- that fits on top of the valve spring that the keepers fit into?
