slave cylinder

[Jason521]

Quick question. I have my 71 521 pick up. Slave cylinder is bad. I have a 1980 l20b in it. Now do i get the 71 slave cylinder, or the 80 slave cylinder?

The transmission slave cylinder has nothing to do with the model of your engine unless more than the engine was swapped. If the transmission was also swapped, lord knows what slave cylinder you should buy. If possible pull the one you have and take it to the dealer.

I prefer the original 521 slave cylinder. It has a return spring on the slave cylinder that holds the throwout bearing off the pressure plate when your foot is not on the clutch pedal, when adjusted properly.

521s has the hose comming from the front so the hose will clear the torsion bar.

saying L20 doesnt mean anything on this situation.Could have come from a Car a L20.

 

you can view photos on Rockauto.com to see differences. trucks will usaully be the same. car were different.

enter vehicle/year and x ref the parts

 

buy the Jqpan made ones. Last 2 I got were from Beck Arnley made in Japan.

But once stocks dry up most are Taiwan or Italian made ones(lucky to get 5 years out of them)

You want to use a truck one.  521 ones use the spring, 620/720 ones do not.  Hydraulically they are identical.  Both will work, but the old pushrod would have to be re-used if it's not the same length/type as what you have.

Thats about what I got was 5 years. Sucks the one i want/need is the more expensive of them all.
