Hello Members   Anyone here give steps to bushing rocker arms. Main  question  is how to get ID of rocker bores  out to  to new bushing  (if even available) OD. Honing seems like it would take forever.  No machine shops around here do it, can't even tell how.to do it. Thanks

Check with Rocker Arms Unlimited. They do excellent work.

Send to Ted - he may rebuild them

Although Ted Eaton and Tim McMaster are among those quite capable of rebuilding your rocker assemblies, it's not likely either will have the time to do it anytime soon. Ted and Tim are pretty much working alone. Tim said that he will not take on any new work for the rest of the year, and Ted is farming out work, particularly heads. Unless you can find a competent shop that's local to do it, you should at least give Rocker Arms Unlimited a call. They are located in Anderson, CA, just south of Redding.

Thanks for replies. Not wantiing  someone to rebuild,  would like  too know how  it is  done. Building a fixture or jig to hold  arm for boring and reaming?

Send an email to Ted (eatonbalncing@yahoo.com). He is at Bonneville Speed Week, so he probably won't reply until next week. I've never done what you're attempting, but it might be a bit technical to accomplish from a distance. 

if you can find some  one with a older  valve  refaced they should have a attachment to reface rocker at contact aria(rocker to valve stem. then use a brake hone to clean up the shaft bore. for sure the rocker shaft will need replacement. then you block off the spill tube bymakeing a screw tp go threw rocker stand(tap the hole to take5/15 coarse thread. the set screw will  block the spill tube hole as well alight the rocker shaft  to line up  oil in. while rocker shaft is replaced make sure valve seals are all intact
most of the time  the rocker shaft is junk.(you must be sure lots of oil is coming out spill tube
ther is plenty of drain holes to handle the flow from rockers.
the rockers fastest from spill tubes  will show the most galling.
I have performed this procedure on a number of cases. with spill tubes  not blocked rockers  at other end don't get much oil. if headed  have bin off and new style gaskets  used you don't need tin spacers as they are the same thickness  as the new style head gaskets, so geometry of rockers is now the same as the thin head gaskets

Ok, this is going to be very hard to describe but let's try. I have done this and rebuilt a set of high ratio rockers for a spare motor I have and they came out very nice. What I did was made a jig to mount rockers in the lathe. The jig is a round stock about 3" in dia with the center cut out to about 1.5" or so. Off of this base I welded on a "post" with a hole for a bolt, you mount the rocker through the adjuster hole. I'm going to try to post a photo ( hope it works). Also from the round base there is a bolt and a nut that is used to adjust the rocker so it is perpendicular to the lathe center line. Now, if you install the round base in a 4 jaw chuck, you can center the rocker's bore where you want it and cut away. be careful centering the bore as the wear on one side could throw you off here.  

Nice one!

Thanks 1946  any chance of putting up a pic of rocker mounted in jig.   As I understand for  each  rocker  it must  recenter  /realigned every time a different one is mounted?
