Assembly number

• PV305

Roller count is the only check that matters

The five roller and six roller builds of these dozers use different adjusters, and the same model number was built both ways, so counting the bottom rollers on your own machine is the check that decides this purchase. Five rollers takes the shorter PV300 assembly with rod AT36391. Six rollers takes this one with rod AT113396. The 450, 450B, 450C and 450D have no six roller listing at all. PV305 is an aftermarket assembly number rather than an original equipment number, and no collapsed length is published for it, so measure against the unit you remove if length matters to your repair. The recoil spring is listed separately in this family, so confirm what your repair needs before you order.
