What mark said is good.

I would add that you could barely do it with a hack saw, due to angle and
due to how long it would take.

Btw, it's very easy to remove the bell housing, and that gives nice fat
access to the shaft if you are going to cut it in situ.

 

One thing I would have minor concern about cutting it in place is fine metal
particles going around and getting into tiny recesses of bearings and pivot
points, like the cross shaft. Would make for a fine grit to wear or jam
things. 

So far I have shortened all mine after removing the shaft from the
transmission.  It's awfully fiddly and even maddening to do sometimes if
it's a difficult one, and I can appreciate the desire to shorten it in
place.

Subject: Re: Cut tranny input shaft while still in tranny? (for engine
conversion)

 

I cut them in the tranny. I use a heavy duty cutting disc in a Dremel,

while someone else turns the shaft. I work a ring cut deeper and deeper

as they turn one CV flange and hold the other still with the tranny in

gear. The shaft is pretty hard and gets hot so I have a rag soaked with

water wrapped around the rest of the shaft and another that I use to

periodically cool the tip.

 

After the cut I use an angle grinder to put a bevel on the edge of the

tip, again while the shaft is turned.

 

The Dremel blade is an abrasive type with fiber reinforcing.
