Additional Information

The Muncie 8405/6A Series was designed as a drop-in equivalent to the TG8S-U6807, TG8S-U6808, and TG8S-U6809 PTOs, with the -09 variant covering the 09 speed ratio position. The integral air shift mechanism eliminates external shift cylinder plumbing at the mounting face. Three speed ratios are offered across the series (07, 08, and 09), all sharing the same ductile iron housing and 8-bolt mounting pad. Part number 8405B-09-P3KX is also referenced as 8405B09P3KX and MU8405B-09-P3KX.
