K321 reassembly
 

I have started to rebuild the K321 putting it back together today. I have the valves in, camshaft and governor gear, etc. My questions is am I going to have trouble matching the camshaft to the crankshaft and get it in time. What I read briefly in the Manual shows how to put it back together using the balance gears. I am leaving those out of the reassembly.

So, what are the suggestions to be sure its in time when I put the crank back in matching to the camshaft.

I had been waiting for some warm weather, now its here, and I'm anxious to hear it run again. I have lots of jobs for it.
Thanks for the help

I would assume just matching up the timing marks on the cam and crank per the manual.

Oh yeah, no fair. I am still saving my pennies up to get the crank done. Can't put mine back together until then. Oh but when it finally starts up.:biggrin2:

Dave, Just match the timing marks on the cam and the crank like the manual shows. It's much easier to line them up without the balance gears.

Thank for the info, I really hadn't read that close enough about putting it back together. I was getting tangled up with the balance gears, and wasn't seeing the marks on the crank and camshaft. I see the mark on the camshaft, the crank is not right here with me at the minute. I also see the "C" on the camshaft.

K321 block
 

I started to rebuild a K321, only to find the block cracked and a chunk broken off the bottom of the cylinder wall.

I got a second block, had it bored and when I started to assemble it with new parts, I find an extra hole for something in the block. I am attaching a picture of it, its a hole with a couple threaded screw holes. I will have to cover that in some fashion, otherwise the block is the same as my old one.

What was this hole for, possibly an oil filter? Its the round hole to the right of the camshaft cover.

There is no oil pump so would not be an oil filter. I am thinking possibly a fuel pump maybe? Hoping someone that has seen a block like this will know. I have never seen one like that.

That hole is for an external fuel pump there should be a factory cover that will bolt in its place to cover the hole

Fuel pump block off
 

Ok on the fuel pump. My old K321 does not have a block off plate on it. I looked real quick when I discovered this hole. I can't believe I hadn't seen that until now.

We'll its a cinch I got to have the plate. This is one time duct tape just won't do the trick.
Thanks a bunch guys.

Didn't think I had one on mine either. But you can see the boss where it would have been.
