Perkins 4236 crank pulley
Perkins 4236 crank pulley twin but 1 groove A section and 1 groove C section. Splines 170 die and 160 mm dia----fits 4248 as well--also some 6354 early with splined crank---note it is a pulley only and not a balancer--has no rubber insert--but will fit the spline of the 6354.1
