R 75 KV6 2.5 AT: no locking pin hole found

[Tonimacaroni]

Dear Rover specialists,


While working in a Rover 75 KV6, 2.5 with auto transmission, I came up with some 'timing belt' related questions; I hope somebody can help me.


Both heads were off (HGF) and fully disassembled, for machining the (warped) head surface and to re-profile the valves and valve seats. So the floating cam gears were off.

My question is related to the correct timing belt fitment. FYI: I do have the required timing tools (including a crank pulley locking tool) and I'm very familiar with the procedure I found in old Rover 75 forum threads plus OEM instructions. (I really did study a lot..)
Unfortunately the primary crank timing gear came of together with the pulley, without the crank being locked in 'SAFE position'. So I missed the change to make my own markings. I did not know that this would be required...



1)

I did not found any 'locking pin' hole in the AT 'flywheel', so I'm not able to lock the crankshaft in the so called 'SAFE position'.
(FYI: I did found the correct? holes in the engine 'clutch' housing)
- does anybody experienced the same?
- is this an AT issue?
- is there an alternative option for locking the crank (in the 'SAFE' position)



2)
The 'oil pump housing/primary gear' timing marks do not correspond at all with the 'SAFE' timing marks (arrows) on the secondary belt pulley and plastic cover combination.
Is it true that the marks on the oil pump and primary gear are 'left overs' from the old KV6 engine? (and should not be used!!). And what crank position do these (old) timing marks refer to?



3)
What does the 'SAFE position' mean in real crankshaft position units. Is the 'SAFE' position the TDC position of cylinder 1?
Does anybody has a 'piston position picture' for the 'SAFE crank position?


4)
How to lock the crank in the 'SAFE' position?
Wat I mean is that I can put the crank in the 'SAFE' position by using the 'SAFE' marks on the pulley and plastic cover, but then I have to take of this pulley and the 'accessories plate' in order to install the timing belt. Without crank locking pin, the cranks moves easily while installing the new belt...



5)
Just to be sure: the correct timing is achieved when the 'SAFE' crank timing mark corresponds with the 'SAFE' timing mark on the plastic cover, AND both cam gear sets at the back of the head are 'aligned' at 3 o'clock and 9 o'clock position, using the marks on the gears (and/or using the tool)


Thanks in advance for (accurately) answering my questions.


Cheers Ton
