While adjusting the valve lash on #5, something must have been on the threads of the adjusting screw and jammed the nut. In the process of getting it undone 4 of the threads now look pretty sad!
I can try to buy a file to clean it up, but it might not hold like it should when tightened up.
Does anyone have an old spare rocker arm adjusting screw & nut for setting valve lash on a 239 OHV. I would think it would be the same in several versions on the heads and rocker assy's used in this size block.
I went back and looked at all the screws on the rocker assy's...found 4 more but figured out that these screws are just old and brittle. The edges of the threads are chipping off and getting into the nut threads. Last rebuilder
should have replaced these back then.
Now... since I obviously need a full set of 16 to fix it correctly, does anyone know who sell these. The block is 239 OHV with #EBV (CF foundry) and the head is EBV- 6090-A.
Carpenter's doesnt list my year specifically and no other book I have shows them at all.
Does anybody out there know where these can be found ??
Thanks for the advice guys...complete rocker assy. replacment is a good idea but not in the wallet right now. I was able to clean up the bad screw threads nicely and found that most of my problems were in one of the nuts threads. I then found a nut in my stash of parts that had very good threads but was twice the size of the original nut. Worried about any problems with putting a heavier nut on one rocker (probably woudnt notice in running) I ground the nut down to the original' size and it fit very well. Adjusted all valves and now onto the next ...and the next...and the next...
you know what I mean!
