  • Pit Board Rubbers

    Years ago, got tired of these damn things falling off. Here's my fix. Never come loose again.
    1/4" bit centered on metal strap.  Try to avoid area that rests on upper frame. Spade bit, drilled to just above strap. Mark new hole, drill 1/4' hole, countersink other side for 1/4 allen bolt. Apply contact cement, wait, then bolt together. Done, won't fall off again.

    There is also a very good replacement from PPP, (Pinsetter Parts Plus). I put their earlier version on, (used a clamp on each end), many many years ago and have never touched them again. They make two heights.

      Anything that improves the original manufacturer idea is AOK with me.

      I gave up purchasing urethane products to shim the pit board. I use pine timber, its cheap, readably available and has similar duro as urethane however it has one benifit over urethane. It won't deteriorate with time.

        In a pinch I've used some kicker strips, even cardboard to keep it working. I'll have to try that instead. I've also seen a complete replacement for the shaker, it's a conveyor belt. I can't remember who makes it, but I saw their promo video on YouTube. Weird stuff.

            That's pretty cool. Any idea what it costs. My guess... if you gotta ask, you can't afford it.

              \Don't think it ever became a selling product.

                I agree HP, yes it seems like some of the urethanes do not have a long "shelf Life". They go so long and then just completely deteriorate or explode,(like my ball wheel roller from another post). I went back and checked mine, they don't appear to be urethane luckily. Pretty sure these were put on 30+ years ago when urethane wasn't as widespread. I've also clamped the the old rubber block, (and front blocks), to the frame with good success. Just grind a shallow groove in the middle for the hose clamp. Once the board is on top of it, it can't really go anywhere.
                I installed a number of the green urethane buckets back in the early 80s, ( I put the date right on the bucket when I install it). Last year they all failed except for one by literally falling apart. They would rip right off the mounting bolts.

                  I never had a problem with urethane products up untll the last 15 years or so. Must be a different formula they use these days. The pit board shims are some of the worst for longevity.
