Manifold grease fitting

[birddog10]

So I've got a new exhaust manifold for my Massey 35 and it has a hole on the upper section, for a grease fitting. I'm assuming it's a grease fitting because my old manifold, which is still on the tractor, has a grease fitting in the same place. At least it appears to be a grease fitting (small nipple like protrusion with the end that looks like a ball point pen). My new manifold didn't come with the fitting so I guess I need to buy a new one or just take the old one out and reinsert it. But my question is: "What the heck does a manifold have a grease fitting for?" What needs greased or lubricated? I've asked a few friends who are somewhat mechanically inclined and they are stumped:confused2: So I'm asking the experts on this site for more information
Thanks for any input.

That's where you grease the muffler bearing!

You got me on that one. :confused3: Can't see a reason for it.

Does the manifold look like the one in the link below? If so, where is the "fitting"?

Greasing an exhaust manifold would be the start of a very bad day.

The hole is probably for an exhaust pyrometer to measure exhaust temp, though I've never seen one mounted on a Massey. I'm guessing the previous owner also replaced the manifold, and was at a loss as to what to plug the hole with. Noticing a grease fitting was the right size, in it went.

Can't say I'd recommend greasing it though.

An exhaust gas temperature gauge is all I can think of also. A requirement on turbo motors. I don't think the 35's came with a turbo.

No, it looks like this, in this link:

and the hole in the center, upper section, is where the "grease fitting" has been screwed in.

Perhaps this manifold is common to another engine that does have a turbo?

Put a grease nipple in it and confuse everyone when you ask them how much grease you should put in!:thumbsup:

Put a steel plug in it.
