Hey guys. I have a BPUxxx reversible plate compactor that I've sunk a bunch of $$ into lately. trying to get it running right again. It needed new bearings on the rollers (where the weights are) but I the shop that did it for me orgianally gave it back to me without it working correctly... wouldn't move. I took it back and after another month or so they still hadn't looked at it. I pick it up today tore it down at our shop and put it back together this time it now works great... just reverse from what it should. IE to go forwards you now pull back on the control lever and to go forwards you pull on it. I'm at a loss for how to fix this. All the shop was supposed to do originally was change the bearings... no one around here knows how to work on these big tamps since none of the contractors seem to buy them expcept me. the biggest thing i could rent while mine was down was a 300# unit and mine is a 700#... took forever HELP!
