Subject: [Fot] Different Tr3/4 sleeve design

 

I've been thinking about the tr tractor motor sleeve/liner for a while -especially after a liner  cracked during a race.  
Went to the drawing board (autcad) and put some of my thoughts in a digital cad  format.  

The owner of  LA sleeve cleaned up my drawing a bit and I am glad to see that the project is completed.

 

Some comments - some surprising.

1) each liner is about 200 gm lighter than stock. The liner is shortened to be the same   Dimension as the depth of the pocket in the block. 
2) it is substantially stiffer than stock and holds machining tolerances much better.

3) the .040" groove is .035" deep to accept a .040" wire. (Square wire or round)

4) the wire groove on the surface may not need a wire -as the edges on either side  in the groove impart an increased unit surface pressure on the gasket.  The gasket will dimple into this recess and lock. 

5) there is only a single flat on opposing liners.  My understanding of having multiple flats was to rotate and hone the liners during engine/tractor rebuilds.  

6) cooling efficiency not tested.
