Help needed 1.7 puma (Sigma) fit in Sylva J15
I am trying to fit a 1997 Puma 1.7 (Sigma) engine in my Sylva J15 chassis. I came across this bit preventing the insetion into the chassis at the near
side bottom rail (the bit with the joggle downward).
I have looked up the Ford TIS manual but cannot find this part referenced, I am sure it is there just a bit of a needle in a haystack at the
moment.
Questions:
1) What is it for?
2) Any consequences in removing it temporily?
3) Anyone else found this problem?

A pic of where it was on the engine may help 
Looks like some for of sensor to me. Is there any electrical plug on the end?

(I think) it's a detent spring/plunger on a selector shaft (5th gear?). No problem removing it to fit the box as long as you remember to put it
back.

Agree with above, it's a detent plunger. Put it back in once the engine is fitted and you should be ok.

In this case...
The selector shafts have a grove in them, that when moved to select a gear, the spring loaded detent drops into and retains the shaft in that
position. Just strong enough to retain the shaft in position but weak enough to be overcome when changing gear. It's what gives the gearchange
it's nice, positive feel.
Detents (of different designs) are also be used to prevent 2 gears being selected at once and on gear lever assemblies to prevent accidental reverse
selection.
