accelerator motor pulleys

have been having a bitch of a problem lately with 6 and 8 `pound balls not making it thru the retarder. Check underlane track and everything is o.k. Accelerator belts are in good condition and even have been replacing retarder carpets with new ones, but still having problems. Only cure seems to be changing the motor pulley and going to the 2 and 1/16 pulleys, but man they aint cheap.
Anyone done anything special for a problem like this?

Marty:
Think this was previously addressed. not certain what thread, but involved supporting covered wagon with a peice of lane patch material, resting upon cribbing, underneath longditudinal of wagon.
Rest assured, not a problem isolated to you.
Would'nt really want to go to different speeds, unless problem has existed since installation. Very hard to handle 100 percent parameters, much less, in the case of six pound versus 16 pound balls, 2.67 parameters.
NASA dosen't work under those conditions.
The very reason the Manuf. gave up on trying to control above ground ball returns.

Re: accelerator motor pulleys

One thing you might want to try but not practice as an ever day solution is to spread the track alittle bit. Or in some cases pry them together. It usually takes 2 good size pry bars. Maybe this might help. Good luck.

Marty:
One thing I neglected to mention concerning changing speed, I have seen V belts with a small V pulley on motor, used with no problems whatsoever, runs fine on large flat pulley.
Cheaper too.

Re: accelerator motor pulleys

Have not done it myself, but have seen the v-belt arangement at other centers. seems to work fine.

Re: accelerator motor pulleys

am I reading this correct? instead of the 45.00 motor pulleys I could get a v pulley and belt and it runs on the accelerator pulley too? Did find the answer about acceelerator wipes interesting. One guy has been on vacation last week, and the other guy was not changing the wipes. So dirty they were almost stiff. Installed clean ones and didnt have any trouble this morning with 18 lanes of lights balls. Have to keep an eye on this one.

Re: accelerator motor pulleys

I wouldn't recommend going with a larger accelerator pulley because of the added strain on your power lift clutch up front, due to the higher ball speed. Our center has had to replace 2 in the last 2 months for just that reason. Have you inspected the vinyl track insert strips in the subway? Worn or cracked strips have a tendency to slow down a lighter ball. Hope this helps.
