Coulton Posted May 9 Share Posted May 9 Anyone know the Mack part number for the kingpin kit for the Type III steering knuckle. It has the needle bearing on the top of the kingpin. I assume for the FA505 front axle. When did Mack switch from a bushing to an upper needle bearing on this kingpin? What application of axle was this used on I know the B used it but did the R model. What vintage of axle? Quote Link to comment https://www.bigmacktrucks.com/topic/74139-mack-kingpin-part-request/ Share on other sites More sharing options...
Freightrain Posted May 9 Share Posted May 9 I think my FA517 axle has that pin. I have to dig out receipt and see what the part number was. I did the pins 22 yrs ago. I have all the paperwork in a folder. 1 Quote Larry 1959 B61 Liv'n Large......................
