Stock Rocker adjustment

[viper15]

Can anyone tell me how the stock rockers get adjusted for preload. I have not taken it apart yet. Not even sure what the look like. are they like the gn?

They are different than the GN which is rail mounted, the TTA uses stud mounted rockers due to the center bolt valve covers on the fwd heads. Not sure on the exact pre-load as it depends on the courseness of the stud threads, probably 1/4 to 1/2 turn after zero lash, but need to check Spec Manual, can check when i get home as I have a TTA Factory manual at home.

They are stud mounted but are not adjustable.

I yorque my stock rockers to 44 ft/lbs on sock heads and flat tappet cam and lifters. No problems for me.

Thats the answer I was looking for. Thanks

Yep the factory instructions calls for 50-65 Nm (so 44 ft lb is in the middle) and your done.

There is no adjustment on hyd lifter's however i soak them in motor oil for a few hrs.

Aren't these a fancy version of stud mounted rockers! Never seen them mounted the way these are..but hyd lifters are normally adjustable by setting the pre-load/lash..unless they are like the GN or the TTA with these spacer deals in there in place of the fixed mount rail/shaft. This way makes them a no brainer, never had to mess with the rockers on any of my TTAs before, guess I'm missin out
