TDC 'timing bolt' to crankshaft pulley perkins 4108

[pcatterall]

My manual suggests that there is a bolt into the timing cover which can be screwed out and located into a hole in the rear of the pulley.
There is no such bolt on either of the 2 engines with me now. Although I have marked the pulley and case at TDC it seems like a useful idea to have.
I have no idea of the size of this bolt or where I can get one. is this common practice on many engines?

Section K2 in this manual any help? ... At least there is a picture of the timing pin so you know what you are looking for.

Thanks for that. The pic confirms what I could see on the diagram. My engines just have bolts holding the timing case. I guess that one of these is replaced by that 'special' bolt ( I forget the name of those long headed ones) I guess that when tight it clears the pully and you would have to slacken it to move the pin at the head into the hole in the pulley back. It sounds like a special bolt I guess.

Dunno about common, but the Perkins Prima have holes to use pins to line things up for the timing belt. And the Ford 1.8TD I had used a special bolt put in the side of the crankcase to stop one of the webs at TDC.
