Gasket Material

Mtjohnso · May 25, 2015

I have an orphan dozer (Windolph) that gaskets are not available for.
The area that needs the gasket is the cover for the bull gear. My initial
thoughts are to take a piece of roofing felt (15pd) and a ball pien hammer and
start tapping away. The area is about 18 by 20 that the gasket will cover.
Have not seen that large a piece of gasket material in the auto stores.
So what material is recommend for this? What would you use?

I would probably just order the correct gasketing from a place like McMaster Carr. They probably have 5 or 6 different kinds of useable gaskets.

I think roofing felt would work just fine. Cut 2 right away. You are bound to tear one before you get it on.

I use roofing felt for gaskets with great results.

poster board makes good gasket material .

Roofing paper will rapidly deteriorate in an oil environment. Underlayment paper for wood flooring would be much better. Using a thin coat of #2 permatex on both sides would improve it. Following is a commercial gasket paper source. Jim

Never thought of roofing felt, that should work, also if you get it super clean you can use the silicone sealer like all the car engines are put together with, after it dries you can trim it off with a razor knife and you can't tell it was there.

I'm with Janicholson--do you really want to go through all that work putting it back together only to have it leak again? Roofing felt isn't designed as a gasket material, especially for a difficult application like this. The link below is a high-strength oil-resistant sheet that would work much better for your application. 30" x 30" will run you about $53, but you'll be able to use the center for other gaskets and it's a whole lot cheaper than a teardown.

Get a tube of gasket maker called Right Stuff. It is some really good gasket maker. Spendy but worth it.

The only time I use paper gaskets anymore is if I need one where it shims a bearing. Otherwise I use Permatex aerobic gasket eliminator, or clear silicone.

x2 on poster paper,used it for years

Right.

And I've seen a lot of half arsed mechanics do more harm than good by slopping everything full of silicone. I rebuilt one Buick V6 engine 'cause someone had slopped so much silicone on the intake gaskets that the water passages were plugged. And I once was on the losing end of a situation where some idiot used silicone instead proper gaskets on the valve covers on a Chevy 6.2 diesel. He left a half inch gap on the bottom side so oil almost ran out in a steady stream. Do you know what it takes to pull the valve covers on a 6.2?

There's no substitute for the proper factory gasket.

I'm with Goose on this one. If it had a gasket from the factory it should have a gasket again. I have seen a heater hose fitting plugged with silicone and an oil pressure gauge line plugged with it and I was the culprit both times. Today a tube of silicone goes bad before i use it all.

6.2 and 6.5 used silicone for valve cover and oil pan gaskets from the factory.

Spook · May 25, 2015

(quoted from post at 19:19:22 05/25/15) 6.2 and 6.5 used silicone for valve cover and oil pan gaskets from the factory.

Yup, but it was applied by a computer controlled robot arm. You couldn't do as good a job by hand in a million years.

Napa has gasket material in rolls of differants sizes. I just looed it up and they have a roll 18"x50 yards . They may have smaller rolls if you talk to them.

Dan Richardson · May 26, 2015

When you say 'cover' I assume you can pick it up. If this is so take it to a shop that makes gaskets. I've done that several times with head gaskets.

moresmoke · May 26, 2015

That why I prefer the Permatex gasket eliminator. Like any mechanic work silicone requires the proper technique. It has its place. Nothing to plug up in a bull gear.

Billy NY · May 26, 2015

If the bull gear is in a final drive housing, like a typical component on many track type tractors, you really need to seal it up, if it leaks, it can also take in water or foreign materials, more so in wet or immersed conditions. I have used Napa gasket materials many times over the years. The link below may also be very helpful.
