722.118 transmission - rear 4 pronged slotted nut - which special tool?

G'day Folks,

It looks like I might need a special tool to tighten the rear 4 pronged slotted nut on the output shaft of my 722.118 transmission...

In the special tools catalogue on this site and others it lists 2 different types. They are conveniently called labeled as the ones for "the large nut" and for "the small nut" - as I only have one nut I have no idea which nut my nut is!

My nut happens to be a shade smaller than the outer diameter of a 32mm socket ~ so guess it is about 37mm in diameter.

Does anyone know?

Also does anyone know what the torque limit is for the installation of the nut?

Thanks to you good folks (with a copy of the now quite rare ATSG service manual) in advance.

Torque for slotted nut - forgot to say

The torque specification for this slotted nut is

12.0 mkp according to the ATSG manual and this has been confirmed to me by email

118 to 120 Nm

(Conversion mkp to Nm multiply by 9.81 or ten if you are lazy!)

Update

Warning - The information posted above might not be correct

This has recently come to light =>

4-Prong Socket for 722.120 Output Yoke:

The part number could be

115 589 08 07 00


Please note I didn't buy either of these tools as the replacement nuts are 12-point nuts - I didn't see the point in buying another special tool to remove the old nut (if the new one was going to be different).
