We purchased a Yale Forklift in need of loving care and serious repairs Have replaced brake assembly, Fuel pump and tires. Are rebuilding inching valve. Problem now seems to be with the Transmission. moves in reverse but no movement forward. We believe we need to replace clutch plates and/or pressure plates, but unable to find any numbers on the transmission. Hoping someone has worked on the 2 speed auto transmission and can tell me where to look. Trying to get correct clutch pack rebuilding kit. Any ideas?
