Buying a c60

[wonslung]

I just found this c60 but the vin has me a little confused. It seems to be a 1968 c50 based on the vin but it's a c60 based on the badge.


I found this on an old farm. It sat for a little over a year. The only issue I can find is the broken alternator bracket. It had a sort of rigged bracket. I'm going to find one at a junk yard tomorrow I hope.



Any info would be helpful. It seems to have a 4 speed transmission with a 2 speed rear. I've never driven anything like this. I'm guessing I do low 1, high 1, low 2 high 2, etc etc.

Yes, that is typically the shift pattern, but with the truck empty, you can probably leave the rear in High, and shift it like it's a 4 speed. 1L is really Low. That looks like a 50 to me, I think a C60 would have spoke wheels.

So the c60 badge on the cab is wrong?

Like Leonard1 said unloaded you can leave it in high and just drive the 4 speed. Look at the GVW a C60 will generally be around 19500. A 60 could definitely still have those wheels that you have, mine does. Looking at your pictures again I see the Gross is 19500 that's the weight on my C60 and I have a GMC 6500 in the yard that the gross weight is20000. Im not sure the 50 would have the 2 speed. Theres a different segment on the site for heavy haules somebody over there can tell you better Im sure.

I noticed a few things about the engine that you should probably fix right away. There isn't a PCV valve (or no breather, if it does have a valve is in the RH valve cover), which could make a sludged-up engine. There's a lot of rubber fuel line. There shouldn't be that much. Also, that Performer RPM intake manifold is designed for a aggressive-cammed, high revving, light weight car. Not the best choice for a Goodwrench engine in a truck.

Dump trucks get battered, Consider age and construction vehicles. the front end could have been replaced with the engine. Long ago I replaced the front clip of my C60 with 1 off of a school bus. Nice truck! needs some TLC.

A C50 typically would still have the 2-speed rear, IIRC.

The reason there isn't a breather and a Pcv valve is that I removed it trying to get it running.

The fuel wouldn't pump so I had a buddy start it while I poured gas in the carb. I just didn't put it back.


I need an alternator bracket. Someone told me I can't use one off of a light duty truck due to the 2 belt alternator. Is this true?

Where can I buy the brackets and mounting hardware for this trucks alternator?

Negative. We have a couple C60/C6500's that have budd wheels and one C7500 with budd wheels. It all depends on what they were ordered with.

Just like the other gents stated, empty you drive in high rear only.
I used to drive a flatbed over a long grade with that same set-up and when loaded to the max+ it was necessary to use all 8 combinations. Shifting becomes second nature after a short while. -Brian
