<VV> CORVAIR CAM GEARs

[N2VZD at aol.com]

i agree with all of this , plus i like the gears with the safety ring. i  
was buying them from federal mogul years ago with no troubles ever on the few 
i  installed. Clarks has them now.
 i put the cam in the freezer overnight, heated the gear in my shop  oven 
then they go together "snug"
i do about the same when installing guides in heads, i keep my guides in  
the freezer.
the old reclaimed built in oven is just right for 2 heads.
ps: make sure all surfaces are very clean , including the inside of the  
holes.
also , study how to support the gear before the actual moment. i put one  
together for someone that tried it with not correct support that broke his 
new  gear.

Timothy,
 
Proper procedure (IMO) is as follows:
Freeze cam with key and thrust washer installed.
Heat new gear to around 400 deg F.
Quickly press gear in place (where it bottoms) and HOLD it there until  
assembly returns to room temp.
Thrust washer should be held tight and not free to rotate around  cam.
Never never install a gear a second time no matter how good it looks.  
(i.e., ALWAYS use a brand new gear)
