Is there any part numbers for a 5 speed?

[dastunboy61o]

I was wondering if theres a a badge number for a 5 speed team used in the 620 datsuns I came cross one Im gunna nab it up and may swap my 4 gear trans out.

[datzenmike]

There was a 5 speed badge on the back of the bed if 5 speed equipped. '77s had them

[dastunboy61o]

I came across one that might have had a 5 speed in it which it had a 5gear head knob on the shifter I'll have to look on the back of it again

The plate number I snapped

[ggzilla]

That's from a 1977. The 1977 model year for a 620 started sometime in 1976.

 

I wonder why there are two dates stamped on it? 1/77 and 12/76?

[dastunboy61o]

That I don't kno. I was ripping disk brakes off a 83 720. The spindle and all came to look more at this truck. So I asked myself if it had or has a 5 speed which would be better then the 4

 

I bet they made it in 76 called it a 77

[ggzilla]

Practically all cars/trucks made in late 1976 -- Fords, Datsuns, whatever -- were 1977 models. The model year traditionally starts in October, but for same model even earlier, although sometimes later.

 

You can buy 2013 cars now. Even though last time I checked it was still 2012.

It's werid like that it seems like there a year ahead lol

 

I have a dodge charger stamped 11/75 came out in 76 tho

[datzenmike]

The first 5 speed was an option on the '77 model year which could have a production date of as early as June '76. The shift knob may say 5 speed and there may be a badge or a decal but after 35 years, anything could have been swapped into it to keep it on the road.

 

The best way is to identify the transmission yourself by looking at it. A four speed will have a narrow rectangular cover plate held on with 6 bolts and have a small round breather vent on it. It is located on top of the tailstock several inches forward of the shifter.

 

 

 

The five speed will not have this.

Thank you that's really helpful would it be a direct. Bolt up to my 74 dastun with the l18 would have to change out the fly wheel and clutch plate ?

[datzenmike]

It should bolt right into a '74. To be sure measure the length... it should be 31.5" long, same as the 5 speed. Use your release bearing collar that's attached to the clutch arm on your 4 speed. They should be the same but just to be safe. The collar is matched to your L18's pressure plate and should be kept with it. Pull the old bearing off and replace it now. Sure as shittin' it will start making noises next month if you don't, and that means taking the tranny out for a $20 part. Yes spend the money on a good one.

 

[datsunaholic]

No. You would not need to change out the flywheel, in fact you already have the rare 225mm 5-bolt clutch IF your engine/transmission is original (or at least your flywheel is). Either way, doesn't matter, just use the throwout collar from your EXISTING setup, not the one from the donor (it should be the same, but sometimes isn't).

 

Identifying a 5-speed: Only surefire way is to look at the transmission. Having the 5-speed sticker on the tailgate isn't a sure thing. The dataplate will not give any indication; they didn't ID the gearbox on the dataplates until 1980-81.

 

Oh, and the reason for the 2 dates is that the truck truly has 2 manufacture dates. You have the date it was built in Japan, and the date it was "assembled" in the US. It was a way to get around the "chicken tax", which is a 25% tarriff on light trucks imported into the US. By doing final assembly (bolting the beds on) in the US it didn't qualify as an import, until that loophole was closed in 1980. Which is why all light trucks for the US market are built in North America now unless shipped in as CKD units.

[datzenmike]

Doug's right the L18 standards had a one year only 5 bolt 225mm flywheel not found on any other vehicle. All other truck and car 5 bolt flywheels are 200mm.

 

[dastunboy61o]

So it would be a rather easy swap then when I do this ? Keep a few parts off my old trans to throw on the 5 speed in turn check the fly wheel for the 225 spacing ?
