ROCKER ARM ASSEMBLY PROBLEM

Keep at it, it`s probably just "krud" buildup on the shaft. Lay every piece out so you can put everything back on the shaft in the same place. When re-mounting the assembly to the head be sure to use a thread sealer on the short tower bolts, otherwise oil will eventually seep past the threads and oil will puddle around the spark plugs..

thank you very much sir. i overhauled a 1940 engine several years ago and had no problems. i thought maybe the Buick engineers have changed things since then. would it help to apply a little heat to it?

The front (OOPS, 2nd tower has a set screw on top. Be careful with the heat, towers are not steel.

Yep.  The towers/pedestal is aluminium. It needs to become warm, to expand, while the shaft stays as cool as possible. A little twisting around the shaft ,back and forth, goes a long way

i have a 1952 Buick engine 263 Ci. inline 8 cyl. i started to disassemble the rocker arm assembly and ran into a problem right at the start.

i can not get the alum.pedestal to slide off the shaft at all. can someone please tell me what i am doing wrong?

just pull a rocker arm back against the spring let it go and it'll snap the stand off.

Try it ...you will like it. :) 

 

Worked for me way more than once. Kind of intuitive.  An in line spring driven weight (hammer), guaranteed to strike the tower squarely,  with a repeatable impact force  and just begging to be used. Easy peasy........................Bob
