Poly-Locks, not tapped far enough? I'm having trouble with some poly-locks from DirtTrackThunder.com. I loosen the allen head screw on the inside of the poly lock all the way, and then when I goto set my valve lash, the rocker stud starts hitting the allen screw before the valve lash is properly set. These are poly locks for a stud girdle, so they are taller than normal poly locks. So, I sent that set back and get a second set in (I have to pay for shipping), and I can get about 4 of the 16 to work. So, I change out all my studs for a set of stock-length rocker studs. Now, I can get about 12 of 16 to work. I call DirtTrackThunder.com to get replacements for the set of poly locks and they said they can't help me any more. Anyone got any ideas of what I could do to make these poly locks fit? or any ways that I could be making the mistake? I cleaned the threads of the poly locks with a tap, and it didn't help. Any ideas would be helpful. Thanks, Ryan |
Knock the end of the studs off with a grinder. Sounds like your heads didn't get milled down enough when you got them set up for screw-ins & guide plates. |
The heads are Sportsman IIs, and I took the guideplates off because I have self-aligning rockers. |
Anyone else got an idea? I'd prefer not to cut the rocker studs... |

Had the same thing happen with my Summit stud girdle. I ended up grinding a few thread off the top of the screw that goes into the poly locks which allow me to back the screw a little more. I actualy use a dremal and a vise at the time. There was pletty of threads to do this btw. It seem that when they made the poly's they didn't tap the threads deep enough or something. Ron |
