  • PBL drive belt different lengths??

    Good morning all. (well it is morning here)

    Can someone tell me if there is a difference in legths between the 70 and 30 PBL elevator drive belts. I was working last night in an undisclosed location and the rear roller shaft was grinding into the kickback. My first thought was that the retainer for the bearing was no longer any good so i went to change it and it was fine. It wasn't until i had a really good look and noticed that the drive belt was loose. I replaced the belt and low and behold no more grinding. Now the place i was at had 70's and 30's at one stage and i am thinking that someone might of put a drive belt from a 30 not a 70. This is not a major drama i am just very curious if there is a difference.

    If you are talking about the carpet drive belts that also turn the PBL lift then these are your measurements. The 30 machine used an A133 (or 133 inch) belt. The 70 machine uses an A112 (or 112 inch) belt.

      <font size="2" face="Verdana, Helvetica, sans-serif">Yes, tinpin, that is correct.

      Be careful though...the last few orders from AMF for these A112 belts were from belts made in Korea. They are a little too long and cause the carpet to run slow due to insufficient tension. The springs on the belt tighteners (new style) couldn't even help as they were almost back to non-stretched size. I had 2 leftover belts I got from a local distributor, belts made in USA, and work great.

        for 70's there are 112 and 114 inch belts. 114's are suppose to be for pbl/humpbacks, tho 112's can be used, just can be really tight, and vice versa for 114's in some machines

          Can you help me with a part number for the A-114 belt. I just replaced a PBL belt in my place and the belt that came off it was an A-114. I tried to put the A-112 belt on and struggled big time. 2 inches does make a hell of a difference. So no doubt I will need to replace the A-112 belt. Is it possible that it should be really tight? these are some questions i need answering.

          Thanks

            I think the part # is V000-022-099-AA this is a vantage part # but it is a A-114 I had the same prob. at one of the centers I take care of all of there spare belts were A-112 thay were replacing a lot of rear roller bearings and roller brackets because the belts were way to tight.I hope I was some help.
