IIRC there are numbers on the main caps.. and an arrow... i **think** number 5 is the flywheel end!
if youve got a haynes manual you can actually make out the number on they picture and which end the arrow is pointing to..
wonder how i know this random piece of knoledge, its because when i rebuilt mine my mum moved all the stuff and muddled everything up! i ended looking in the haynes manual and saw a pic of the engine and happened to notice the numbers!
I havent got a clue what the torque settings are TBH.. maybe somerthing like 90Nm (wild guess )
