rocker shaft removal #1, #4

Hey guys

In the middle of cam replacement...first time... - 930 to SC. All rockers and shafts are out except for #1 and #4 exhaust. Easy tap out for #2 - 5 ..no issues.

Not enough clearance against cam housings to tap out from back to front through bores for #1 and #4. I was able to push out #1 and #4 intakes opposite way with a little leverage using socket and shortened hex key. No problem.

#1 and #4 exhaust are tight. Any ideas...or do the the cam housings have to come off for clearance and then tap out back to front.

You have to rotate the engine similar to dong a valve adjustment. If you don't, some will come out, others will not. It you rotate every whatever degrees, like valve adjustment, it will work beautifully.
I think this is your problem I hope.

Thanks for the post runner. Not the issue. Rocker is unbolted and adjusted loose. Nut, collar, bolt are out.

Bummer, take a blunt end shaft and use a hammer to nudge it out? Be carefull you don't want to damage the wall/bore. I'd leave the bolt in it. If it breaks those parts are replaceable.

Did it. Same way as #1 and #4 intakes. Used a spring puller to catch the inside ridge of the rocker shaft and pull....carefully....with the shaft of a screwdriver through the puller handle and levered against one of the valve cover studs. Pulled into valley between #4,#5 and #1,2 and popped out.

I wrapped the tip of the puller with shop towel for grip and minimizing damage. 2nd pic shows the orientation on #4 exhaust. (popped the shaft back in for the pic rocker was out from before)
