Throwout bearing

[EdwardK]

I just bought a throwout bearing for my '74. The original listing said it was compatible with a '74, but the packaging says only up to '73.

 

Are there any differences between the '73 and '74 clutch throwout(release) bearings?

 

Actually I've noticed a lot of parts only support up to '73 and the '74 parts seem more expensive and hard to find... Any reasons behind this?

 

Thanks guys.

Bearing likely same,did it come with release collar? Thats the only thing that would differ. Maybe someone can look up part# for 73-74 to see if two diff numbers come up.

620 trucks in the last half of 1972 had the L-16 engine.  I think in 1973 they got the L-18 engine, and by 1974 had the L-20-B engine.

There may have transmission changes too, that I am not aware of.

key is waht motor you have and that will tell us close to what you need

But really there was a 5 bolt L18 flywheel that was a 225mm. its rare. if 225 mm then it usues the L20 T/O bearing.

 

 

ck out rockauto.com and they have photos. but best to remove the part to ck

Early '72 (March/April ?) was the first L16 620 (it was considered a '73 model year). Over a year later in Sept '73, making it the start of the '74 model year, the L18 was introduced along with a longer and totally different 4 speed.

 

My info shows all L16/18 release bearings the same through '74 when the part number changed but still compatible with later years..
