There has been a modification for the cold store spec machines - its to prevent the hydraulic tank from splitting.
The old filter assembly equipment needs to be removed & then blanked of at the filler neck using the sealing screw.
The new filter does indeed go where the dipstick is located & should be changed every 1k hours.
New parts required are:
7564387 Breather filter
7569405 Connection
7564187 Dipstick
203002 Sealing screw
Ping me a email & ill send you a copy with the info across.
