Play in my SRAM omnium cranks ???

I've just installed my new sram omnium crankset onto my Cinelli mash work frame.Its a Std 68mm BB. I've greased all parts as per normal setup. Once I've tightened the non drive side with the Allen key (not with a tourque wrench as I don't have one ) there still seems to be some lateral play .Ive remove the crank arm and retightened it but there still seems to be the same play. I know I need a torque wrench and will borrow one but I've done up the bolt pretty tight .Am i missing something ? There were no spacers in the crankset kit so I assume I don't need any either ?
Cheers Ja

Once I've tightened the non drive side with the Allen key (not with a tourque wrench as I don't have one ).

Get it torqued up properly, allen keys barely have any leverage to get it tight enough.

Ok will do thanks

Take out, grease and in again until there's no play

Insufficient torqage is the only cause of lateral play in SRAM cranks - unless you've done something ridiculous like tried to use a shimano BB.

You don't need a torque wrench - you just need it really tight :) but not too tight :)

Yeah, they need a lot more tourque than you would think to get everything locked down
