I recently purchased this cart and it came with the rear transmission partly disassembled. Does anyone have or know where I can get a manual showing how to reassemble the transmission? I think it is an 08 model, the info plate shows serial number 2010-0334 and manuf. code 20-06-08. If anyone can tell me what year model I have I would also appreciate that info. The cart is a Ruff & Tuff 4X4 Hunter 48 Volt. Thanks in advance for any ideas or suggestions.
