Carpes rubbing agenst BDS

[StunedM]

seem to be having issues with carpet rubbing agenst BDS, brand new carpet (Green carpet P/N 000026756) and new/ rebuilt front roller (carpet rubbing with orignal front roller also), both brackets and pins are in good condition and move smoothly, have inspected the pit also and nothing seems to be out of place. BDS bracket dosent seem to be pushing thr roller towards the deck when the front roller is in place and nothing seems to be binding grinding or grabing, there was no issue with the pit befor replacing the carpet. anyone have some advice? any chance that the new carpet is not straight?

If everything is good in the pit area, I'd try putting a cone spring on the front roller and see what happens. You put the spring on the side opposite the way you want the carpet to go. The spring and washer part numbers can be found in the parts or top parts books

[StunedM]

could you go into a little more detail about a cone spring as i have never heard of a cone spring befor

Is the BDS front roller bracket the correct one? There are 4 different brackets. The BDS bracket for both machines is shorter on the bottom where the spring hooks on. If the OBDS bracket is used on the BDS the bottom of it will hit the cross beam, not putting full tension on the front roller. The old carpet may have been slightly shorter or in such condition that it was able to work and since this carpet is new and nice and flexible, with the wrong bracket this can show up. Are the front roller bracket springs stretched by chance?

i checked the bracket and it moves free and has plenty of clearence but from the moment i put the roller in it has minimal movement. both old carpet and new carpets are the same, the new carpet scrubs agenst the bds wall well over the roller lip

Hi StunedM,

I had a similar problem a couple of months ago, also using a brand new green carpet from one of our Australian suppliers. I'd be very interested to know if it's from the same supplier, because I'm certain the problem was the carpet itself. I suspect the measurements were incorrect on one side, causing the carpet to drift to the larger side.


Mine was running to the OBDS, jumping over the lip on the front roller and scrubbing out hard on the metal kickback. We pulled that pit twice and triple checked/replaced everything; swapped front rollers from another lane without success. In the end I got a pit carpet from a different supplier, put it in without changing anything and away it went...two months now without a problem.

So it has full and free movement until the roller is put in.... hmmm.... the answer is there somewhere.

I just spoke with StunedM on the phone - it seems the carpet he's having the problems with is from the same supplier I purchased my troublesome carpet from. Apparently he also had similar problems with another carpet from the same supplier. I'm putting my money on the carpet causing this - perhaps the seam has been put together too tight on one side or too loose on the other?

[Tablejam]

If the carpet was flipped around and the problems then moved to the other side then I would say your theory has been confirmed.

[StunedM]

theory has been confirmed i rotated the new one and it ran and scrubed to OBDS, found a old AMF green carpet and put it in. can you guess what happned.....? it went straight, so after replacing a carpet 5 times in one day i dont think i will ever order another carpet from Eastern Bowling again

[Tablejam]

5 times.....that's too much for anybody!

[Stoctster]

Thanks StunedM, I feel your pain!! I lost patience after the 3rd time - as much as I wanted to test my theory I simply didn't have time to try flipping it over. Think I'll be giving the supplier another call about the one we bought....was speaking to the head tech from our other center up north and he reported having the same problem with the same type of carpet. Might try to measure the faulty carpet and see what the difference is.....

stoctster we've also had the same problem with those belts. we had about 3 in a row that did the same thing. changed to different belt and problem gone, will never get those belts again

Well that's very interesting - I spoke to the supplier and they said they'd sold hundreds of them without any issue. Doesn't sound like that's the case. Will definitely be getting back in touch with them about this, seeing as it seems many people are having the exact same problem. But you're absolutely right - I won't be risking it buying any more of these belts.....
