Where can I find a cork+rubber radiator gasket?

Postby vfrf2 » Tue Sep 06, 2016 6:20 pm

For a 52 Cub. I've found a few cork gaskets, but no cork+rubber ones. If anyone could point me in the right direction for a source it would be much appreciated.

Thanks.

Rob has you pointed in the right direction. I don't know if TM's is rubberized. You could call and ask. That being said, what they sell works fine. You could also get material from an auto parts store and cut/punch your own.

I can vouch for that. I've had theirs on since this spring with no issues. I personally believe if it wasn't quality, TM wouldn't sell it.

If you're concerned about it, apply a thin coat of RTV sealant to both sides of the cork gasket. I've done that and had no leaks whatsoever.

Just replaced the radiator...purchased everything from TM. Sprayed copper coat on both sides of gasket and bolster. No leaks so far :)

Change in plans. I've decided that I don't want to wait, so...I picked up some cork/rubber gasket material and a set of Harbor Freight hollow punches (for cutting the bolt holes). There are a few gaskets that need to be replaced anyway and I plan to make as many as I can on my own. The investment in the punches is well worth it. I've had good success with making my own gaskets in the past, so why not have a go at it on my Cub? The key is taking your time.

This was actually a bit more than just changing a radiator gasket. Here is my experience, after doing a lot of research here I decided to tackle it. My original one has suffered from the frozen bolster syndrome along with a few leaks in the radiator itself. To make a long story short, my first attempt was a complete failure. But, the important thing is to learn from it, move on, get it done. I pulled the new ebay-purchased radiator off and threw my straightedge down on the bolster's mating surface and found a noticeable hump. I milled it down manually with a series of files and a couple of hours of time invested. I made my own gasket with Versah cork/rubber gasket material, put a real thin layer of rtv blue on it. One thing, test fit everything before you slather your rtv, or sealant of choice on to it. Whatever you do....don't overtighten the gasket! I can't stress that enough. I threw down too much pressure on the cork gasket during the new radiator's first install. Squished out the sides, it was hideous. Anyway, I learned from my mistakes and hope to pass on a bit of what I had to deal with. I have a very small crack in my bolster just above the crank hole that needs to be addressed. I'm thinking about trying the JB Weld route that some have had success with.

A couple of other notes. Chase and clean all 18 bolt threads. Get new bolts and washers. you'll save yourself a lot of trouble. You can get kits, but I just got mine at my local hardware store. You'll need 4 x 5/16" -18 x 3/4" bolts for the corners of the radiator posts. 14 x 5/16" - 18 x 7/8" bolts for the rest of the radiator.

I always hear horror stories about bolster to radiator gaskets. I pulled my radiator to check for leaks while I was working on the mechanical end of things and picked up a cork gasket from a local guy that has a lot of old new surplus parts.

When it was time to fire up the cub for a test run I installed the gasket dry knowing it was coming back off later for paint. I figured if I had a small leak or two no big deal on a rebuild test run. Surprisingly, not one leak.

It's almost time for a final installation after paint. I plan to use spray copper on it then. It will probably leak like the devil then, haha! I think for the most part people trying to over tighten things on this part.

Just my 2 cents.

GS 1411 calls for only 20 ft lbs of torque. If you're not using a torque wrench it would be very easy to over tighten. My wrench only goes down to 25 ftlbs, so thats what I went with and it worked fine.

Thanks for the torque spec. I can use that piece of information later. A have a wrench that goes down to 16 lbs. I used my lowest setting calibrated feel the first time. I'll check to see how close I was to the 20 lb. nominal when I pull it back off just out of curiosity.

The thing about it is, if you do research here on your own before you get into it, it's a much easier task. If you have a straight, crack-free bolster, a radiator swap or gasket change is a relatively easy undertaking even for someone with basic mechanical skills.
