start from the middle and work to the edges. not from front to back or back to front.
just go
14 10 6 1 3 7 11
. 12 8 4 2 5 9 13
and so on.

Both my Nissan Factory service manuals show the same as MikeSmith wrote. Here is my dodgy pic.

mine says that for the p40, and this is from a proper nissan publication, nissan patrol 160 & 61, publication No: SM4E-0160G0 is that the same as yours? i might just have a bad copy.

Both my manuals are the same P/N as yours. the drawing for the P40 has the same tightening sequence as the L28, just that No 1 starts at the top.
Weird they are different.
