Something you don't see anymore

And that is where you would connect your cable under your gas tank. Governor will work if you do it this way.

Time to meet my son at the bus. Then, I need to dip some nuts in the pool. Engine is done. I can try to post pictures later.

 

[sparkwizard]

I do this with the engine upside down so I have a place to put the rod cap and bolts.

 

[sparkwizard]

Actually, I wear bifocals and it us just easier to look down. P!us, no oil leaks out, any tools I drop fall into the piston, not on the ground.

 

[sparkwizard]

This crank needs to come out before the cam will come out. Line up the timing marks and they will come out together. The head is still on it, the piston is in it and notice the valve lifters didn't fall out on the ground.

 

[sparkwizard]

Now slide the new crank in and reinstall the rod cap. Torque the bolts to 100 inch pounds and reinstall the cam.

 

[sparkwizard]

Slide the cover on and torque the bolts to 75 foot pounds.

Here is where it got interesting. The starter drive from an old 4 horse would not fit on the end of the splined crank.

 

[sparkwizard]

I went in the garage to remove the drive from my rusty stuck junkyard submarine engine. It has been on the floor with automatic trans fluid in the cylinder for a month. Well it moved and it is not stuck anymore. That big pipe wrench did the trick.
I took that 5 horse starter drive to put on this 5 horse crank. It didn't fit either.

 

[sparkwizard]

So I installed the original cup and nut from this engine. The flywheel, nut and key all fit this crank. The shroud wouldn't fit.

 

[sparkwizard]

I removed the nut and starter cup, put the nut back on and used a cutoff wheel to trim the cut the end off the crank. Problem solved.

 

[sparkwizard]

Now it was time to split the gearbox and install it. This piece bolts to that special red side cover.

 

[sparkwizard]

There is not anything fancy inside. No clutches, no little spinning planetary gears, just one big gear with the 3/4 inch PTO on the other side of it.

 

[sparkwizard]

When mounted, it rides around that splined crankshaft. I think the ratio is six to one. I didn't count the teeth.

 

[sparkwizard]

All back together. Time to put it on the power hoe.I plan to pressure wash it tomorrow and figure out what to use for a front wheel. I have 30 at oil for the engine. I think that's what is going in that gearbox too.

 

[sparkwizard]

The tractor wheel needs to come off and be turned around. New chain, pulley, belt and figure out how the belt tensioner clutch was designed to work. This will be fun.

 

[sparkwizard]

Well, after physically lifting it up, removing that WATER FILLED tire, and bolting the hub back in the other way, I gave up trying to get the axel back into it alone. Remember when I said I need to put a front tire on it? Make that TWO FRONT TIRES.

 

[sparkwizard]

This is what I recovered. There was a flat bar welded on one side with a bolt to hold one front wheel. These two square head set screws were sued to adjust the height and width, roughly.

 

[sparkwizard]

This is about what it looked like originally. Pretty primitive.

This is a sweep. It digs into the ground from 1/4 inch to maybe an inch. It pulls weeds out of the ground between the rows in a garden and pushes some dirt toward the good plants. There is an adjustment for it's angle of attack above the blade. This thing will dig trenches with a different blade bolted onto it. The DEPTH of cut if adjusted by the front wheels and the guy walking behind it.
