F61BVA75064
trying to find new kingpins. any help would be greatly appreciated

 

Does it still have the 300 Six?
L = 6,000 front axle w/PS



You probably want the service kit 3111
Maybe axle C7TZ-3010-A for '76 F600 w/6M capacity.
"Pin and Bushing kit (Spindle)":

• Std. -size pin C7TZ-3111-A
• .010" Oversize pin D3TZ-3111-A

Those service kits fit a lot of different capacity axles, so probably a good bet.

From $40 at eBay





Several aftermarket sources

Bear in mind that you will need to finish ream the bushings to achieve alignment and proper finish clearance after pressing them into the spindle, and that very long reaming tool is not one that you can rent at Autozone.

 

F61 = F600 gas, 4x2

B = 300 1V HD six in-line gas engine

V = Kentucky Truck Plant

A75064 = 1976 numerical series, November 1975 production

158 = 158 inch wheelbase

No color code. Note special order truck and it appears door has been changed as the warranty tag is held in place by screws instead of rivets.

F611 = F600 gas, 4x2, 20,200 lbs GVWR

AA8
AA = Black Leather Grain HD Vinyl
8 = Standard Cab, cab and chassis vehicle

3A
3 = Dana (Spicer) model 7231-B three speed auxiliary transmission (Does this truck really have an aux. transmission? This seems wrong. )
A = New Process model 435 four speed transmission.

F3L
F3 = Eaton model 15201 two speed rear axle, 15,000 lbs capacity, 6.33 / 8.81 ratios
L = Ford 6,000 lb capacity front axle with power steering

20200 = 20,200 lbs GVWR

479098
47 = Cincinnati District Sales Office
9098 = Special Order Number.

Could be a typo, could it have been ordered that way?--a 300 six with a 4 & 3 in front of a two speed rear axle? Sounds shifty....

But thanks to @asavage for actually answering your question. Good luck with the kingpin job.

 

its still got the 300 6 cylinder. purrs like a kitten and starts easy as can be, im tickled with it.

 

I don't think its got an auxillary transmission. its a 300 6 cylinder with a 4 speed and chelsea pto.
