Max4 T 20 chain adjustment

[Delduck]

Can anyone tell me how much slack should be in the drive chain (T20 to driveshaft) for a max 4 with tracks

I was always told 1/4" movement in the primary chain from the T-20 output shaft. That's what I did on my Max IV, and I don't have any problems.

Thank you
