Anti Seize question.

[Tractor Boy]

I have a 2007 Kubota B7800, the problem is my clutch release rod seized up in the aluminum bell housing. I would like to know what type of anti seize or other lubrication to use. I didn't realize there were quite a few different types of anti seize available. Copper, Silver, Zinc, Nickel. None specifically say steel and aluminum application. Unfortunately it is a one time lubrication, so I definitely want something that will at least last till the next clutch job. The tractor only had 160 hrs. and is garage kept.

I don't know if your tractor is exposed to salt air, even though it is garaged when not in use. If so, you can follow what boaters use regarding sacrificial metals for outboard motors. Look up on Google: sacrificial metals chart and study what would work for your application, air composition.
Fluid Film might also work since it leaves a protective film behind to reduce corrosion.
I've used copper and regular anti-seize for years, but am not in a salt water environment anymore.

It's possible that your tractor was exposed to a salt environment during shipping to the states, on the slow boat from Japan....
Once corrosion starts it will continue if unchecked. Most any coating now will help, vs. nothing applied.

All of the anti-seize products that I am aware of and certainly all those I have, are water soluble to some extent and as such, will wash out.

What I use that is inexpensive and sticks like glue is "Wedge Brake Grease", you can get 8oz jar for about $4. Once applied, it isn't going anywhere. It is NOT an effective lubricant for ball joints and other places one would normally use grease, but it works great where component WEAR OUT is not the primary goal.

I have use the regular Anti-Seize on my prop shaft on my boat for years. It has not washed out. Make removing the aluminum prop from the steel shaft a breeze since most changes are in the water and the prop is partially submerged. Should work fine for your clutch.

I like nickle.. but if you are looking at steel/aluminum.. hard to beat zinc..

Any of them will work in that application, as well as many other lubricants.

Zinc is recommended for steel in aluminum.

Tractor,

Aluminum expands when it corrodes, so your problem may be corrosion more than plain old seizing. If any of the parts associated with it are stainless steel, don't use aluminum based anti seize.

Maybe zinc based antiseize or just some kind of marine grease. Or the wedge brake grease that Mod suggested. Maybe drilling out the hole a bit will solve everything.

Blue or Purple Loctite.

I prefer red.

I prefer red.

You need heat to remove fasteners with red. Quite a bit of heat.
