How old is the ball machine? Parts already out of production?Just tried to reorder that part. Their reply was “No longer available and no plans to remanufacture...”. But they would give me 20% off a new machine. Thanks, but no. Going to try a repair/rebuild of this one.
I have the same problem but I can’t find anyone who sells a new detent. Did the bicycle inner tube work?Update on my attempt to repair the detent. After removal of the detent I noticed a small tear in the rubber tube at the inner edge of the steel detent tube. My assumption is that “leak” allowed the tube to fill with air when the blower was on, making it more difficult for the ball to pass through. Removed the tube by untaping the wrap, and removing the outer hose clamp which allowed the steel tube to spring open enough to remove the inner band that hold the rubber tube’s other end inside the detent tube. While I had the rubber out I measured it: appears to be 2.125” ID and 5” long. Reinserted the rubber and stretched it a little more toward the outer edge so that the tear was outside the detent tube and would be covered by tape. After completing reassembly and testing it worked fine. Ran a tub of balls through with no issues. I don't expect the fix to last forever though. So, knowing the concept of the rubber tube and detent fit, I ordered a 16”x 2.125” bicycle inner tube, which I suspect, when a piece cut to 5” long is used to replace the tube it should work fine. No guarantee though, but short of buying a used parts machine may the only way to salvage an otherwise usable ball machine.
Hard to described how the detent is assembled (should have taken a few pix) but its not brain surgery and anyone with a detent problem should attempt this repair before throwing in the towel and buying a new machine.
