How to read 620 VIN numbers

[Datsun Parts]

I need some help. There are a few starting variations of the VINs on a 620, what is the difference?

 

KHL620

HLG620

PL620

 

Standard cab, Long Bed, and King Cab I thought? Help Please!

[datsunaholic]

No.

 

This only applies to 620s:

 

If the first letter is a "K", it's a King Cab.

 

"H" and "P" are engine codes. In a 620, "P" is the L16 (72-72) and L18 in '74. In Nissan terminology "P" is an uprate engine (No code was a J13 engine, not used in the US in 620s). "H" is for an L20B engine.

 

"L" means Left Hand Drive. No code means right.

 

A "G" following the drive side code means long wheel base, which only applies to the longbed (both the King Cab and 4-door had LWB frames, but did NOT use the "G" chassis code).

 

In the US, only one code was used from '72-74: PL620.

 

In '75, 2 codes were used: HL620 and HLG620.

 

In '76-79, 3 codes were used: HL620, HLG620, and KHL620.

 

There also was a code for cab/chassis trucks which I can't remember. You'd see that on trucks that had unit-body campers or other specialty bodies, although many of those were actually regular trucks with beds that were converted.

EHL620TUA and EHL620TUVA were the only two Cab Chassis codes used. Calif. and non Calif. They only came with a 4spd and none sent to Canada.

Wow great details. The last question is the frame stamp on the trucks. I thought it was on the frame right near the alternator, is that the case of all models?

[72 327]

Yes unless like my truck DMV or Highway Patrol moved the VIN. Mine is now in the door jam and nothing in the engine bay.

What are the numbers after 620,(PL620xxxxxx). i was reading that the first digit is the build year, but what are the rest. I want to find out if my truck was originaly an automatic. It had a four speed when I purchased it, but the wiring harness is from an automatic. I want to know what rear end I have.

No way to tell from the VIN what transmission it had. Nissan didn't start adding option codes to the VIN plate (as separate entires) until 1980.

 

However, if you have a non-stock 4-speed (such as a 71-series) which was used in 74 and beyond, it's a better possibility that it was an AT-Manual swap. Also the gauge cluster will be different (M/T ones had a kickdown switch, AT ones didn't).

[butcherboyjc]

Thanks. Whats a kick down switch?

[datsunaholic]

The kick-down switch was just a little switch in the speedometer that told the carb to go to idle when below 5MPH or so. It engaged the BCDD cut solenoid on the carb, vs the Automatic which used the inhibit relay on the fender (controlled by the transmisison). Only way to find it is to look for the wires coming out of the speedometer, because the switch is inside it, though the amplifier was mounted externally on the back of the cluster.

Hi gang.

 

Have a 620 instrument cluster. I believe it's an older model. Came with my truck as extra, but mine works just fine. This is collecting dust.

 

Would like to sell fast so please make an offer.

 

PM or email me via the link.

 

Thanks!

 

 

Is that the amplifier? The square box on the back of the speedo.

[datsunaholic]

Yes.
