Installing roller bearings in stock rocker arm assemblies...

I learned a long time ago, while involved in various engine development programs to never take any aspect of what everyone else was doing as the right way, or only way. Many time people started down a paticlure path, and rather then back up and regroup, when the results don’t achieve the results they anticipated, they make the rest of the program revolve around their error, and compensate all the other parameters
 
some one sent me one of these a while back , forgot who. I have some offset rockers for the intake only being done ,

Now see thats what I'm talking about . A simple easy cheap mod to eliviate the galling associated from the cast rocker inbedding itself into the case hardened steel shaft.

Question is now..... what bearing was used and was the original trunion turned down or was a new one made OR is there one on the market that can be used for this app?
 
It would be best if you could turn down the trunion so you could do this to a truck that already had wear. If you must buy new trunions it only adds to the cost...

Can't see the pic from work (stupid restrictions)...

I've got a spare set of rockers/trunions and just need some info on bearings to get started...
 
I can get this done , its fairly simple , wished I remember who sent me this part , its been a long time ago.
I have been working on a bushing as well

Greg, thanks for the offer. I may take you up on it. I heard Harland Sharp was making rockers for these but couldn't find them on their site or a few of their dealers? I'll do some more looking tomorrow.

The rest of your discussion on studs, pushrods, springs, and retainers will do no good with me as your parts are already here :Cheer:(thanks to Pure Diesel Power).

Here's a couple teaser shots of the build... too bad such a pretty engine will be going in such a dirty truck :hehe:

do you have any more info on that water pump?
 
it leaks, what more do you want to know about it? :hehe:

some others have had complete failures with little run time as well. I'm getting ready to swap back to a clipped stocker...

I'd be very interested in info on the bearings, mod to trunions, etc

I noticed some significant galling on mine with only 52k when putting in the helix 2. Cylinder 3 was so bad that I couldn't even move it by hand.

WHO LET YOU IN THE GARAGE??
GET OUT OF MY VALVE COVERS!!!!!!!!!!

Just kidding!
For those who want to know they can be had for $14-1600.
 
so 1500 for the broken one in the picture or 2 grand for new ones that will wear out in 3k miles

i thought pro mod was expensive
 
Wear on the lower third of the rocker shafts & rocker levers is common - HPC coating new or unworn shafts is the most cost-effective solution, while machining an additional oil passage into the shafts' O.D. is a cheap way to further decrease wear caused by insufficient oil film... obviously, the oiling system's long time-to-pressure upon start-up is a significant factor.
