Don G 1947 Posted June 6, 2010 Report Share Posted June 6, 2010 So here is my problem. I need a gasket about .007" thick for the drive pinion bearing retainer on a 3 speed manual trans. I can't find any gasket material that thin. I need that specific thickness to hold the drive pinion bearing in the proper place. Anyone have a suggestion for me. Thanks for your help.

BeBop138 Posted June 6, 2010 Report Share Posted June 6, 2010 Not sure how big the piece needs to be---would bearing shims from rear ends work? Small sheet brass comes thin at metal surplus outlets--good luck:confused:.........Lee Quote Link to comment Share on other sites More sharing options...
Don Coatney Posted June 6, 2010 Report Share Posted June 6, 2010 I used to make differential gaskets from paper grocery bags. Not sure of the thickness but my guess is it would be close once compressed. Quote Link to comment Share on other sites More sharing options...
pflaming Posted June 6, 2010 Report Share Posted June 6, 2010 Don, you have been around corrugated material. If one went to a corrugator and got a piece of roll stock would that make a good gasket. Grocery bags are probably recycled paper and might crush better yet roll stock might be a bit stronger. Just wondering. I was going to try to use e-flute for my interior cardboard but I think it would absorb too much moisture and eventually delaminate so I abandoned that idea.

Don Coatney Posted June 6, 2010 Report Share Posted June 6, 2010 Thickness is the issue here. Grocery bags are most likely made from re-cycled material but once they are oil soaked no water should affect them. It has been years sence I have used them but I believe they would work as well today as they did then. Quote Link to comment Share on other sites More sharing options...
Don G 1947 Posted June 7, 2010 Author Report Share Posted June 7, 2010 I was thinking about using bag paper, but wasn't sure if it would make a tight enough oil seal, but it sounds like some of you have done that. Do you think I would gain anything if I sprinkled a little wax on the paper and then melted it into the paper with an iron (when the wife wasn't home)? Seems the wax impregnated paper might give a better seal and be more resistant to deteriorating. What do you think? Don Quote Link to comment Share on other sites More sharing options...

What do you think?Don I am slow on getting on line, but like Don C I would also suggest using a grocery bag. Years ago I needed a cover gasket for my oil pump and the only material that I found that both sealed and gave a good clearance on the gears was one cut from a paper grocery bag. Worked just fine. Not sure how the material or thickness of those have changed over the year but they probably are similar enough to the paper bags of yore that I'd consider using them as source material.

John-T-53 Posted June 7, 2010 Report Share Posted June 7, 2010 A good thin gasket material I've used in the past is the cardboard back to a gum-bound paper note pad. Works great alone...and seals better with spray gasket adhesive. I've used this for the axle to backing plate seal and pumpkin seal. Quote Link to comment Share on other sites More sharing options...
Robert Horne Posted June 7, 2010 Report Share Posted June 7, 2010 Most paper, such as printed material, magazines, etc., is .005, and is a compressed paper. Paper bags, newspaper, etc. is a soft paper, and even though a paper bag is often .006 or .007 it will compress very much. For gasket material, some auto parts stores sell thin, about .010, material.

1942cowdodge Posted June 7, 2010 Report Share Posted June 7, 2010 I made one here but its so thin that it disappeared. Quote Link to comment Share on other sites More sharing options...
later Posted June 7, 2010 Report Share Posted June 7, 2010 Try Grainger or any store that sells parts for industry and ask for oil paper gasket material. It is like a grocery bag but comes in different thicknesses. It is made for sealing close tolerance gear case covers and is easy to cut to shape. I used in the Navy and still use it at work.

Don G 1947 Posted June 8, 2010 Author Report Share Posted June 8, 2010 Well, I used .010 brown paper and gave it a little wax by ironing it between wax paper a couple of times. Figure that will compress down to about the .007" I need. Thanks for the input and ideas. Don Quote Link to comment Share on other sites More sharing options...

Robert Horne Posted June 8, 2010 Report Share Posted June 8, 2010 I have used copper and aluminum roof flashing material for gaskets also. These are around .006 Quote Link to comment Share on other sites More sharing options...
rustyzman Posted June 8, 2010 Report Share Posted June 8, 2010 If thickness becomes really critical, buy shim stock from a supply house like McMaster Carr in your thickness and make a gasket out of that. Or alternately, wax paper may even work. Obviously, problem solved on this one, but maybe if needed in the future. Quote Link to comment Share on other sites More sharing options...
