Chevrolet transmission bearing numbers

Maybe the attached scans are of use for anyone wanting to make there own gaskets (please check size on normal paper first before using actual gasket paper!).
The brown coloured gaskets are the ones I made myself on gasket paper as suggested by Grant. The black ones are the ones that came from a set I bought (can't remember which supplier it came from).

I actually used the homemade ones, and ordered a set as a spare....just so I could continue with the gearbox.

Please note that there is some difference in the gasket for the prop shaft side between the ones I made myself and the one available commercially. The one I made myself was actually copied from the one that came from my gearbox when taking it apart.

Hi Alex

I've been using a similar method to produce gaskets. My method is to scan into my computer at High Resolution either a new gasket or in the case of smaller parts putting the actual part on the scanner and scanning them. I then send the image from the computer to the printer which I load Manila Card Stock in and print out a nice full size gasket. Spray Permatex High Tack Spray on both sides, with two coats it saturates the card stock.

Your method of adding a ruler to the scan is a good double check on the size that the computer, or printer is not trying to out think us and re-scale things. Your PDFs are a good add to the MLU knowledge base. Have you already cross posted to the How-To heading?

Nice thing about this approach is you need a gasket you just go print one. How are you punching the holes?

Hi Phil,

I am using a variety of hole punches; a set with larger diameter punches in a red case as shown in the attachment, and another cheap Chinese set for smaller diameters. I am actually using the same set on rubber and canvas webbing as well....which works OK so far. Just make sure you are using the punch on a piece of soft wood, thick rubber or a cutting mat to protect the cutting edge from damaging.
Larger holes in the gasket are either cut by hand or done using the ball peen hammer method.

I always start with the holes and than cut the inside and outside contour of the gasket.....that works best for me. Doing it the other way round can lead to very thin areas in the gasket, or even cutting the gasket in half, if you punch the holes just a bit off.

Have you already cross posted to the How-To heading?

I have only added tips from others so far, but should make some updates anyway

Yes, the function "scale to fit" is killing with this sort of stuff....it's easy to miss and your print may look 100%, but may actually be 98,7%!
