Which way does it go?

[Kurtb]

I purchased an overrun clutch for the PTO. It came with a rolled pin but being the mechanical genius that I am I can't find where it goes so what holds the clutch on the PTO?

Also, the thermostat I purchased goes in the upper radiator hose- Does it go near the block or near the radiator? Facing which way?

Gratefully, KB

Remove the grease fitting(s), line up the holes in the ORC and the PTO shaft and shove/tap the roll pin in. Make sure the ORC OR's, then reinstall the grease fitting, grease'er up good and you're good to go.
Thermostat goes in closest to block/head and pointy end goes to radiator. Some put a zip tie on the radiator side to hold it in place.
HTH.

Bill, you're right about the ORC, and that the thermostat goes as near the block as you can get it. I'm questioning your orientation of the thermostat.

It seems to me the "pickup" of the thermostat (that is, the thing that senses the temperature of the water), should point to the block. I think you want it to sense the temp. of the water in the block and open when the block reaches the set temperature, right?

While I've been lucky and have never had to remove or replace the thermostat in my 9N, I assume it's built like an automobile thermostat, which has the sensing device in what I would definitely call "the pointy end."

Am I missing something about the shape of an N's thermostat?

The 'pointy' end goes to the radiator, as I can attest from personal experience by putting it in backwards. See tip # 25, below!

I've never had one out either but the manual says "be sure the bi-metal spiral end is toward the engine".

Hopefully I can figure out what that means if I do have to take it out! :lol:

The older thermostats covered in the manual used a bi-metal coil as the actuator, rather than the "wax pellet thermostats" made today.

On the bi-metal coil thermostats, the bi-metal coil was the heat-sensitive element, and was intalled with the bi-metal element nearest the cylinder head.

On the newer thermostats, the wax pellet is encased in a shiny copper or brass housing.

That is the part that goes toward the head on today's thermostats, since it is the heat sensitive element.

the pointed end on top is the side toward the radiator
