GMC 1962 - 3/4 t - Long bed - 305ci - 4 speed

[Sponge]

Hello,

I'm Dylan and I recently purchased a very nice GMC truck.
It has its nice patina, imported from California, 3/4t, long bed, 305ci V6, 4 speed SM420.

A very nice truck which is quite rare where I am living, in Belgium, Europe.

I'm now waiting for my insurance; getting the license plate then on the road!
I'm planning to do a good maintenance in the following weeks: oïl, coolant, brakes, rear axle and transmission.

I'm planning to leave it as is, stock, no mods at all except a radio I think.

Thanks


Dylan

Welcome Sponge from across the pond!

Nice truck and cute kids. Dig those chrome valve covers and kool to see pics from abroad and the neighborhood too.

[TJ's GMC]

Welcome! And super glad your leaving the v6 in there. To many people take these perfectly good engines and dump them for sbc's. Glad your another in the crowd keeping it. :ok: Dig the chrome valve covers!

[Sponge]

Thank you guys.

I agree, chromed valve cover isn't nice but keep in mind it is quite hard to find stock GMC valve cover with gasket over here.

I would need to find used one with a set of gasket in order to keep the stock look but not on my priority list for now.

I'm discovering this beast because here it is a big truck, way bigger than my familly car in length and width hey hey...

I also noticed the water temp gauge doesn't read anything, I put the wire to ground and Nothing so either the wire is cut somewhere or not connected or worst thing, shot water temp gauge.

The speedometer doesn't work but the cable is there so got to check if the gear cable isn't cut in the cable housing or it is worst or not.

Other than than, check this out, for the radio, the previous owner trimmed the radio opening so I'll suffer to find something fitting into this....

I think you might have read us wrong. lol Dig the chrome valve covers means we Like them. haha It's rare having chromed ones on a v6. :thumbsup:

[bigblockv6]

The chrome valve covers look great:thumbsup:, don't worry to much about a total stock look under the hood, I had my valve covers chromed on my 68 K2500 and wouldn't have it any other way,:upyes:

Got it. My mother language is french so I understood to dig a hole and dump those valve covers in the hole ahahah

You guys and your slang!

:bump5:

[Funky61]

If you burry them I'll dig them up and keep them. Have you seen the Plaid vale covers?

Yes I've seen but not my style.

Question for the expert; according to the VIN, it is a 1500 and I've got 8 wheel lugs front and rear.

Should I assume I've got a Dana 60 at the back?

[TJ's GMC]

1000 was considered a half ton

1500 and 2500 were 3/4 tons.

Should be an Eaton H052 or H055 I think. I don't have a 62 manual.

[bigblockv6]

!500's to 66 were 3/4 to so it would be a Dana 60. 2500's to 66 were 1 ton and those would have the Eaton rear Diff:ok:

That's interesting, my 60-61 manual states the 1500 came with an H055 with the option of 4.10 or 4.56 gearing. I was under the impression those were Eatons?

[bigblockv6]

It may have been a heavy duty option, I've seen them with 60's as well.

Which 1500 series? P1500 (Step Van) series did use the Eaton rearend. As far as I can figure out and what I've seen the majority of 62 1500 series pickups used the Dana 60.

I'll re-quote,

Model 1000. Standard SM318 trans. Standard Axle H035. Ratios 3.07 and 3.92 available.
Optional trans 177 CA HYD. or SM420.

Model 1500. Standard Trans SM318. Standard Axle H052 Ratios 4.56 and 4.10 available.
Optional Trans 300GH HYD and Sma420.

Model P1500. Standard Trans SM318. Standard Axle H055. Ratio 4.56
Optional trans. 210U HYD

Model 2500. Standard Trans SM420. Standard Axle H072. Ratio 5.14
Optional Trans 300GH HYD.

That's what the 60-61 manual says anyhow.

[bigblockv6]

It's also saying Model 1000 with HO35 rearend? That's odd because it's pretty much common knowledge all 1/2 ton 1000 series pickups came with the Dana 44. I guess we will only know if someone out there with a 60-61 GMC 1/2 or 3/4 ton pickup has a Corporate GM rear rather than a Dana 44 or 60:banghead:

This manual is a reprint so it could be chevy and GMC mixed. lol Heck, my 64 Chevy C20 has a H052. My 66 C10 has a GM 12 Bolt.

Then it's most likely not correct! Figure 60-66 1000 series Dana 44 and 60-66 1500 series Dana 60:ok:

[GMCDAC]

Welcome from South Dakota! Even though this is from a 10 year newer GMC, a Dana 60 still looked like this I believe, except cleaner and less rusty! I also "dig" your whole truck---LOL! The experts here may correct me, but did you know that the grill GMC logo appears to be 1966?

[WDShaffer]

Photo of correct grill letters attached. It took me a while to find them (and a while more to spend $$ on them). At least you have a GMC hood, I was not so fortunate.

I'm gonna email you a picture of the axle under my 64 GMC. lol I'm curious now. haha

That's what I've got, so a Dana 60.

For the oïl in this thing, Something like 75w90 GL4/5?

[James]

From the research I've done, if it is a Dana 60 there will be a number 60 on the back side lower right web below the right axle tube. here is the picture of my rear axle.

75W-90 or 85W-90 will be fine. :thumbsup:

Took a gander under my 64. It's a Spicer or Dana 60 or dern close to it. I think in 60-61 they used the Eaton and in 62 they went Spicer/Dana. I need to get my 64 manual ordered.

[Clarke]

My '62 1500 has a Dana 60. Several years ago I pulled the 4.56 open carrier out and put in a PowerLoc 4.10.

I'll disagree:pullinghairout: with you on the Eaton axles being used on 1/2 and 3/4 ton trucks. I just talked to Jake Groby who has a 1960 GMC that he restored that came stock with a Dana 60. You have to remember Canadian model GMC trucks were basically rebadged Chevrolet trucks and all the running gear was identical to Chevrolet trucks, while US versions mechanically were different as night and day. Your reprint manually is most likey derived from the Canadian version.:ahhhh:

Those nice center caps I've got, is it standard in US? Any good reference on Amazon?

[AZKen]

Do I see a 56 Chevy? Parked on the street? Very nice!

It is a limited slip with a 4.1 rear end ratio.
The oïl I bought is AP GL5 75W-90. Do I need additive?

[Sponge]

Few pics...

No worries, I bought the appropriate oïl for my rear end.

[Sponge]

I did a big maintenance work on this bad boy and I'm almost at the end.
I cleaning the electrical wiring, removed the radio, check almost everyting and it looks great.

I need to fix my speedometer thing and it should be alright....

Few pics.
