Cargo Weight.

Postby jungerfrosch » Tue Apr 29, 2014 5:53 am

I just picked up a '65 320.

I see in the manual there are three different cargo weight capacities, U, UN, and UP. How do you tell which one it is? In the manual I see there were different trans and axle ratios, and different springs and wheels.....is this the only way to tell or is it labeled somewhere?

My truck seems to be a UP, based on the spring configuration and the very old 600-14 tires, I haven't checked axle ratio yet. Springs and obviously tires can be changed though. I can't even imagine putting 2000lb in my truck though.

Check VIN on car, trans, engine..etc. That should lead you in somewhat of a correct direction.

Hey! Original bumpers! Funny added hood ornament.

Does it currently run?

Jungerfrosch,
Congratulations. Neat old survivor '65. Should you ever change your wheels/wheelcovers, and consider parting with the hubcaps, I'd appreciate a shot at them.

No, it's currently not running, the engine is free though and I'm hopeful that it won't take much.

I'm planning on keeping it stock so I will be keeping the hubcaps, sorry. I was actually wanting to find some replacements as a couple of them are rusted through in spots...but from what I've seen It looks like I will be repairing them.

jungerfrosch,

First welcome aboard! Truck looks nice. My one '65 had some aftermarket greyhound hood ornament from a Ford or Lincoln that was properly removed and then ceremoniously smashed with a sledgehammer and ran over a few times.

A few weekends and you'll have it running. Their pretty simple to work on and contrary to some parts are available. You just have to know where to look and what's compatible from other models.

Weight capacity - that's a good question. I have several little 320 and each one has a different spring count, difference in spring thickness and bump stop bolted to the frame. Somewhere I read the difference, let me do some digging.

In the mean time let us know if you need any assistance.

cheers,
Li'l Truckie

jungerfrosch,

Found the Spring thickness and count to answer your question. So here is a couple of screen captures from the 320 Service Manual put into a jpeg for you -

enjoy

So then the only difference are those things mentioned in the manuals; tire size, rear spring configuration, and trans and rear axle ratios?

The frame, axle and front suspension are all the same.

That's my understanding.

I'll snap some photos of my springs with a mm ruler and post later this evening as I have a few different combinations.

But seriously, a little 320 hauling 2000lbs of cargo, I can't imagine :rolleyes:

Well here's a combo photo of my 320 rear leaf springs.

Image

Should be easy to ID the 320-U with only three leaf springs.

But as for the UN and UP, I probably should have taken better pictures and pulled out the micrometer and measure each leaf spring. Without a doubt the bottom spring is 12mm. However, the other four are a little to close to call in these photos. I'm guessing these are all the UN with each spring at 4mm as I do not know what the rubber helper is?????

Should the rubber helper not be on the leaf spring assembly or is the manual mean the top bump stops? No idea at this time.

cheers,

Here is a picture of my rear springs. I rotated it and cropped it so that it would be easier to read the measurements. This is just ahead of the axle on the drivers side. It looks like 1 12mm, 2 6mm, and 2 5mm to me. I think it is interesting that the UN actually has heavier springs than the UP, unless they are somehow different other wise.

Is this the same as what your trucks have, or is this the "helper rubber" they refer to?

Tad,

I have the same rubber bump stop on the one I think has the thicker 5mm and 6mm springs. So is this the rubber helper the manual is talking about? I'll check the manuals again.

Just a heads up. This rubber bump stop makes bleeding the rear brakes a pain in the butt. I finally just cut a 7/16 wrench down to size for this job.
