Title: ENV Manual cross shaft gearbox
Post by: Guss Honeybun on October 16, 2018, 12:49:23

Hi, Does anyone have any information regarding the gear ratios that AC used in the ENV manual cross shaft gearbox ? Also, my ENV gearbox has the code 22CH in front of the remote mount - what does this mean ? Any help appreciated..

Hello Guss
There is a lot of information about maintenance in the hand book, see action magazine if you want to order.
There were three different options of gearbox, ratios below.
                           Top.           Third.         Second.        First.
Synchromesh ... 4.66 : 1.      6.25 : 1.      9.85 : 1.       16.8 : 1
Sports.          ... 4.66 : 1.      6.4.  ; 1.      9.3.  : 1.       17.7 : 1
Competition
Sports.          ... 4.25 : 1.      5.82 : 1.      8.98 : 1.        15.3 : 1

I would imagine that the ratios quoted are through the differential but sadly I don’t have that information. It is commonplace for top gear to be 1 : 1 in the gearbox.

I can’t see anything to indicate what the 22CH would reference.
