My friend just brought a 2003 52 meter Schwing and he has a problem with the PTO. Now this is the situation, the box doesnt have a serial number or model number and he needs a diagram for it. Any help its apreciated.

Thanks

You can go to www.fabcoautomotive.com and down load parts and service manuals for most of the case used in concrete pumps

Thanks. Now i just need someone that can tell me what model should this pump have.

Eithe a 143 or 270 split case were used on these trucks.

call Schwing, they can look up the pump file and tell you exactly what type gearbox is in your truck
