Identifying F30 versus F60S
 

Some medium wheelbase Ford CMP trucks have turned up locally over the last couple of years. I am a long time Chev C8AX owner and carrier restorer, so Fords are not my forte!

What are the key identifying features to determine an F30 from an F60S?

I have read about size of steering knuckle, size of wheels, inner chassis skin etc, but these vehicles have been in civvie use for probably 50 years so anything is possible.

There are no ID plates remaining, and even registration plates are gone.

Any tips please?

Rob

if you discount chassis size and wheels I think the differences are pretty limited. There's springs - rear C30 has 12 leafs C60S 18 and have helpers, C30 has 4 clips C60S 6.

To quote the MB-C1 manual - "The Model C-30... is similar to the C60-S except for load capacities. The C60-S is equipped with additional rear spring leaves to allow for a greater load."

I assume the Fords followed this pattern. I wasn't aware the steering knuckles were different, I thought all 4wds were the same.

steering differences
 

Thanks Harry

I don't have my Ford manuals handy as they are on loan but I recall there are larger diameter joints, (5" dia versus 6" dia I think), but these may have been an upgrade.

Do F30 have a double skin chassis?

Rob

ah ok, well in my manual under the front axle specs for "universal joint" it lists 5" and 6" but makes no other mention like what they are on. The chassis section is only a page and a half, and no mention of model differences

Differences
 

In earlier production they both had the small steering ends and the small steering box. The larger versions were not introduced to the 3-ton range until later in the war, although I don't have the exact date.

Most of the 30CWT versions have 16" wheels too.

Chassis Depth
 

Can anyone please measure the depth of the chassis rails on an F30 please?

I can then check that against them this weekend.

cheers

Good morning Robin,
It's a beautiful winters morning here in the B O P . I hope it's the same for you in Gisborne.

The chassis depth is as follows: At transfer case cross member 178 mm
rear shock absorbers 120 mm
front shock absorbers 126 mm
According to the parts book some F60s had the light steering box and some the heavy ones but they all had a vaccum booster unit by the master cylinder. F30 did not have a booster.
Even if the booster is missing the mounting bracket and or linkages should be still there if it is a F60s.
Rear spring assembly part no's seem to be the same on all models F30 and up.
Of course F30 wheels were 16" F60s 20".
Hope this is of help.

Regards Terry
