Title: position of shifting forks
Post by: CHR!S/DVK on July 12, 2011, 13:10:58 pm
i just bought a AB short gears gearbox to replace my broken one, it's a used but good one with a number of replaced parts.

the seller told me to check if the position of the shifting forks under the nosecone piece is correct because the nosecone has been replaced.
i already checked my haynes and vw manual but i only find guides while rebuilding the whole box.


does anyone know what to look for and in what procedure?




this should be the image when the nosecone is removed, with the 3 shifting forks (1/2, 3/4 and reverse)

Make sure all 3 are in the same position, install your cover w/hockey stick. Make sure the stick moves freely, torque nuts. Hope this helps.

VW Terminology 101

The shift forks are hidden away inside the gear chamber.  What you are looking at are not the shift forks.  They are the the shift rods or selector rods.

They can push into the gearbox, or pull out.  To install the hockey stick, push or pull each of the shift rods until the slots in them are all in the same plane.  So the tip of the hockey stick can slide freely between all of them.

Do not use that gasket on that gearbox.  That is the early gasket.  Use the gasket that looks similar but with less around the top bearing.

i think i understand how to check the position of these selector rods, thanks for the replies.


now another issue came up.
yesterday i removed the old tranny and discovered that the length from the edge of the nosecone to the tip of the hockey stick rod (that connect to the shifting coupler) is 2cm longer than on my new tranny.

the nosecone housing itself does not seem different (plus, i cannot find different nosecones in shops, they seem all to be for 61-72).
so it looks like it's the length of the hockey stick, can that be right?

i just receive an advise of a friend who said that the gearbox might be in first gear. when removing the tranny it shortly stick stuck to the shifter rod, that might be why..

If the length of the nose cones are the same, and it's only the length of the hockey stick protruding, then the gearbox is in either 1st or 3rd gear.
Take the nose cone off, then pry out the one shift rod that's not in the same plane as the other 2.
