Here's what you do.... a guy on pirate 4x4 told me about these:
he said "...looking at the pictures and your cluster gear you will see snap rings
betweem 3rd gear and the counter gear( that the big gear by the way).
This is where the problem is. the bevel cut third gear while meshed puts
a strain and torque on the snap rings and wears them and eventually
they break. because movement can occur against the snap rings the fix is
simple , remove the countergear from the shaft and discard the two
snaprings and replace with a sleeve. (pictured) it occupies the area
outlined in yellow. This simple fix was designed by "Tourist Auto" in Salt
Lake City,They have been in the manual tranny business for 75 years. They
were extrememly helpful when I walked into their shop . There phone is
801 -364-5743. They sell the sleeve for $7.50 . You will need to tell
them what tranny you have by examining the trannsmission bolt holes and
tell them wether they are threaded or not. (they can explain more) I
guess some years were two of the holes wre threaded. Now that I think
about it though I dont think this matters unless you are doing a total
rebuild.(rebuild kits with bearings were$190 I think..."
anyway im swapping in an sm465 and adapting to my dana300, then putting in my 350.. so if you have any tips or know of where to get a cheap sm465 to d300 adapter please let me know.....
