35' spindles

[ford35lh]

I am in need of a pair of spindles for a 35' pickup.

Ford parts book says 35' 48-3105/6 spindles are
different than 36'-37' 68-3105/6 spindles.

Are 35' spindles the only ones I can use ???

If that is so, how can I tell the difference.

Here are the main differences; but '36 spindles will work using the thinner later nut. The longer '36 steering arm will slow the ratio a little making steering a bit easier.

[ford35lh]

Is the length of the threaded portion the only way to identify the 36' ???
I don't have a 35' spindle to compare.

Any other ways to identify either spindle ???

[V8ER]

'35 spindle has 5 3/4" long threaded arm to the face; '36 spindle has a 5 1/2" long threaded arm to the face. '35 right spindle arm is 1 1/2" between holes; '36 right spindle arm is 2 3/16" between holes.

I took my 35' truck apart about 40 years ago and all the parts were well
organized and stored. Eight years ago I had to move and everything got
stuffed on every empty shelf and nook or cranny.

Sorting thru the pile of newer drums and hyd.backing plates I found a
pair of spindle,drum,brake assemblies that had been cut off an axle.
They were hydraulic and it occurred to me that these were from my truck.
I cut them off as I had heated the axle too much trying to remove the
spring perches.

Pictures show the complete drum/spindle assy. The spindle without drum
and backing plate. The spindle with only NOS drum mounted.

The spindle measures 5.5",the cotter key passes thru the nut easily.
The other spindle has the arm holes 2+ inches apart,so these must
be '36 spindles.

For some reason they put these spindles on my truck when the
hydraulic brakes were installed. The hyd. brakes were an upgrade
that was never finished as the rods were still on the rear and no master
cylinder was ever cobbed onto the frame when I got the truck.

Any idea of the vintage of the drums and backing plates ???

Lincoln brakes

If they all fit together that's probably quite a desirable setup. The Lincolns are an upgrade over the standard hydraulic setup due to them being self energising.

Meant to mention that the spindle in your picture is not a '35 spindle, as the bearing is below the axle boss.

Maybe a few more pictures of one of spindles by itself would help ID them.

A picture of the rest of the axle and wishbone may show that other parts were also changed.

It may be entirely possible that that is a Lincoln spindle AND axle, especially when you consider all the built-up yuk that appears to be in the way of any "recent" swapping. DD

^^ Yeah, I was thinking along the same lines.

I will get a picture of the spindle later today.

It is becoming apparent how the Lincoln parts got on my truck.
There was a short lived car club in town,back in the early sixties.
They were sponsored by and worked on there cars at the
local Lincoln Mercury dealer. I found this truck in the junkyard
behind the dealer around 1968,but it took 5 more years to get it.

Mart,, what exactly is the mechanical explanation of self energizing ???

[Mart]

I'm not sure if I used the right expression. It's the later (better) versions of the drum brake where the Cylinder pushes the front shoe, the front shoe pushes the rear shoe, and they use the forward motion to help wind themselves "on". You get more bang for your buck.

The following might help a little:




When the driver applies brake pedal pressure at the master cylinder, fluid disperses to each wheel cylinder. The curved top ends of each shoe fit against the round anchor pin. As the pistons move outward in the wheel cylinder, the shoe lining contacts the drum. The linked shoes attempt to rotate with the drum. With the vehicle traveling forward, the rear shoe stops against the anchor pin. Backing up, the front shoe stops against the anchor pin.

The obstructed rotational force now redirects, pressing the shoes outward against the drum. This additional force, referred to as “self-energizing”, is beyond driver input and hydraulic pressure. When self-energizing force can apply in either direction of rotation, the system is called duo-servo.





As the vehicle moves forward, the self-energizing force is greater at the rear shoe. To keep lining wear even, the rear shoe’s lining is longer and sometimes of different composition than the forward shoe. With a shorter lining on the primary or forward-facing shoe, self-energizing force is slightly less when the vehicle moves backward. Since the vehicle does not back up at high speeds, braking is sufficient in either direction.

Have already established that its not a "35.
Its 5.5" long

Here are photos of just the spindle.

What I think was mounted on the OP’s truck were ‘36 Ford spindles (verified by him above^) the Lincoln backing plates are the so-called “deep” ‘39-‘40 version with ‘39-‘48 Lincoln hubs and ‘40-‘48 Ford drums.
This combination of parts is a direct bolt on with no modifications needed, only the ‘39-‘40 backing plates have the small 3/8” holes and the same bolt pattern to fit the ‘32-‘36 spindle with no adapting necessary, and all the Lincoln hubs have the same, correct offset to work with original (or repro) ‘40-‘48 Ford drums.
There is the possibility that someone adapted Lincoln spindles, so be sure to check the king pin inclination on the spindles you have. The Ford KPI is 8* and the Lincoln only 4* so the Lincoln’s will give negative camber requiring bending a Ford axle to correct that.

Hi see my add here on Parts For Sale 36/37Ford spindles & 40s backing plates front and rear. The grease shields are included I also have a 39 peddle setup that is tight 150.00 and original master cylinders and wheel cylinders. You can get me at 440-280-0059 or [email protected]. Thank you Jim T.

I just realized that the thrust bearing is under the axle in the photo, wouldn't that mean those are in fact Lincoln spindles? A '37 and later Ford spindle measures roughly 2 15/16" between the yoke to allow for the thickness of the bearing, but the '36 and earlier Fords are only around 2 1/2" and use the thrust bearing at the top of the spindle. Make sure you check the king pin inclination.

Do any of you have a photo of a 35/36 front backing plate.

No two ways about it...that is definitely a hydraulic Lincoln b-plate. DD
