Gasket materials

[sam.coll]

Hi team, long story short I have a Emco FB2 gear head milling machine that has a small fluid leak from the gear box, I’ve stripped and cleaned the machine and would like to replace all the gaskets, being that I’m in Australia spare parts are hard to obtain so have decided to make my own. Just wondering what would be the best gasket material to use and in which thickness? The machine is lubricated with hydraulic fluid (Shell Tellus ISO or equivalents) and all the mating surfaces are in good condition.

Any help is of much appreciation

Cheers
Sam

I don't know if it is appropriate for your application or if it's available down under but I swear by this stuff.

They call it "rubber-cellulose." It's that dark gray paper looking stuff. It's integrated with rubber to give it strength. Very commonly used for a wide variety of automotive applications.

And then there's neoprene integrated cork. It won't take as much torque as the paper, but it will absorb surface irregularities better than paper.

Biggest issue you need to know is the proper thickness the gasket needs to be to account for end play on any shafts that may go into the end cover.

Do you have a photo of the old gasket you removed?

I'm sure you have auto parts stores or industrial supply companies down under. They sell gasket paper, both rolls and flat pieces.

How thick was the gaskets you removed? That will tell what to buy.

Heck, you can even use a cereal box in a pinch. I know of a F600 farm truck with a cereal box gasket in it's axle shaft flange. After 35 years, it still isn't leaking.

This right here.
Also for gaskets thqt dont matter thickness ive never had a problem with Loctite flange sealant. Or something from garlock.

I wasn't even going to mention the cereal box thing because there would inevitably be a internet gasket snob who wasn't worth my time to argue with, but since you did first, it works great and I have done it many times, never a failure.

be sure and get a cereal box whos content is high in fiber.......

as for gasket material its hard to beat 3 bond stuff.When cured the stuff is almost bulletproof

Been using it for years on motocross bikes (center cases) ect... along with my trucks.

I opened the gear box on my wood/metal Rockwell/Delta bandsaw because there was a paper gasket that was leaking gear fluid. I was having trouble getting a replacement and I called Delta parts. They said forget about it and use automotive silicone gasket sealer. It has not leaked a drop for a lot of years and is known to work with the petroleum based fluids. Any Permatex or Loctite sealer should work fine. It is sometimes called gasket maker.

I agree with several other posters that a liquid gasket maker is the easiest way to go. I recommend Dirko HT It is the sealer that Stihl uses for all of its engines
I have never had an issue with it other than being somewhat expensive.

Thanks for the suggestions and advice. I ended up going with Klinger C-4400 gasket sheet in 0.8mm thickness, should do the trick. Away for work at the moment so unable to check the machine. Also sourced new bearings, O rings, seals and circlips. Hoping to have it rebuilt next weekend when I get home.

Only picture i have on phone:

 

[Shehzada]

Yes....that will work. Good luck

My son's lawn mower wouldn't run, I disassembled it, starting with the carb. I told him he needed to get a gasket using the model & serial #'s. He didn't.

This past week he asked me to 'come get it,' he said he didn't need it as they are going to use a lawn service. Probably a good use of his time, they have two boys ages 5 & under.

It wouldn't start, but it had spark. I removed the carb, no replaced gasket, no form-a-gasket.

Necessity is the mother of invention. I grabbed a 12-pack beer carton and cut-out a gasket, after comparing the cardboard thicknesses from what was in the recycling bin. The cereal box, the cracker box, the pasta box were all assessed, and found lacking compared to the beer carton. Of course I had to empty the carton to use it, which required some beer consumption.

Gasket done, installed, made sure the carb passages were clear, adjusted the choke mechanism and the advance to work w/o binding. Fired it up, cut the lawn, came back inside and had a beer. My little buddy oversaw the work.

Becks, that's imported. I hope you set the caliper to metric.

It used to be imported from Germany, and when I started drinking it, that would be West Germany. Take a look at the lower-right corner.

Being owned by InBev, which I believe is the world's largest, now it's made domestically in the 'good-ole-USA.' I don't think I can really tell the difference between the German and the USA Beck's products. That would be an interesting thing to do, maybe some day.

Sometimes I do switch to mm. I was measuring some motorcycle carbs last night, and used the metric button for that. I used the Imperial system/fractions to make this gasket.

I have a decent micro-brewery within walking-distance, Titanic Brewery.
http://www.titanicbrewery.com/titanic/

The oldest in Miami. Their brews are all good, I tend to like a stout, but will try anything. I usually ask for a sample size at a new microbrewery, and order it if I like it. Our son got me a stainless steel growler this year, so I can enjoy the draft of my choice at-home.

So our imported beers are made in USA and our USA tools are imported.

It seems the OP has it all covered, but here is my opinion.

Repairing all kinds of gears one has to pay attention if gasket thickness is issue. Bearing pre-load can be an issue. It all depends.

However, if not, and this is often the case; there is absolutely no reason to waste time making gaskets with all the liquid gasket compounds available. I have probably done it thousands of times already.

Sure if I can get original gasket with relative ease I do that. It's quick and later repairs are usually easier. In many cases I can't since I live in Iceland and we import all kinds of machinery from all over the world. Frequently the junk I am working on doesn't even have any kind of dealer or indeed anyone locally who supplies part for it so next original or even after market gasket is many days and thousands of miles away.

Yes our shop has some gasket material for special cases. Thankfully I hardly ever have to mess with it. I kid you not - there are several air compressors currently supplying air @ 150 psi with the cylinders and cylinder heads sealed with High temp RTV done by yours truly. Originally it was just a test on a small compressor, to save the weekend and to see if the RTV could withstand the temp and the pressure - it did! Next one was more serious based on evidence from the first one - and so on.

In my 30 years of experience, making gaskets for great many things is a complete waste of time and inferior method compared to good liquid sealants. For some reason many people disregard this method.

Big mistake.

Most if not all automakers now use elastomeric rubber liquid gasket material to seal up their engines on the assembly lines these days. This speaks volumes about their reliability and longevity.
