Nothing hard about them, make sure you lube them up and that they are seated correctly on the pushrods. Also spin the crank by hand so that with each pair of rockers that you tension, the piston is on the compression stroke (both valves fully closed), this will ensure the correct tension on the rocker bolts.

There is a bit more to it then that........Even with non adjustable YT rockers. What you have to do is:

Step 1: Turn the engine over untill both the inlet & exhaust valves are closed (compression stroke) on the cylinder you are working on (pull the spark plugs out to make it easier to turn over and go by firing order) Firing order on a Holden 5.0 is 12784563 incase you didnt know.

Step 2: Unbolt & remove old rockers

Step 3: Fit new YT rockers loosely in position

Step 4: Bolt the rocker down slowly while turning the pushrod by hand untill you can just turn the pushrod with your fingers, this is your "0 free play point".

Step 5: Torque the rocker bolt down with a torque wrench to 25 ft. lbs. taking note of how many full turns of the torque wrench it takes to achieve 25 ft. lbs. Now, ideally it should take between one turn and 1 1/2 turns, if its less than 1 turn it will require a spacer between the rocker pedetal & the cylinder head posts and repeat the process. I am pretty sure spacers are supplied in the kit. If its more than 1 1/2 turns then it will need some machined off the rocker pedastal, but this is very uncommon.

Step 6: Repeat process on remaining cylinders.

Which is exactly what I said but in less detail.

Well if he hasnt got instructions he needs a bit more detail........Cant just bolt them down and forget it.

[Not_An_Abba_Fan]

I know, but you just elaborated a bit more.

If he needs instructions, then perhaps he shouldn't be doing the job.....

If he needs instructions, then perhaps he shouldn't be doing the job.....

Everybody's gotta learn somehow.

[Not_An_Abba_Fan]

Putting rockers on isn't like rebuilding a transmission. I understand that people learn as they go, but it isn't that difficult a job. A lot of people tend to over think and over complicate things. I just feel that if this is his first attempt at anything mechanical then he may be starting too high. If on the other hand he has done his own maintenance on his car, rockers shouldn't pose too much of a problem to be needing instructions.

Adjustable rockers are a whole different story.

yeah righto, im a mechaninc and sorry i cant remeber the specs off the top of me head seens i first them on over a year ago.i dont see the problem in asking for them?

[Not_An_Abba_Fan]

A mechanic will know where to get the tension settings from, and how to change rockers. Why ask for instructions on a Commodore Forum? It's like a plumber asking how to change a tap washer.

Torque settings for Yella Terra rockers? And where do you suppose he gets them from?? I would dare say the only place would be Yella Terra! Jeez, someone asks for some info from someone who has done it quiet reguraly and he gets flamed and assumed that he knows nothing!! Some people........
