    1976 620
  1. Thanks again, going to buy the bearing right now.
  2. So a little scuffing is normal....OK, that's good to know. I haven't actually driven the truck with the 5 speed in it, only shifted the gears with it on jacks very slowly to make sure everything works.....knowing that, would you still recommend I stick with the collar that came out of it and just replace the bearing?
  3. I have been following this thread and quite a few others on release bearings and transmission swaps. The above chart with sizes is very helpful however, I have a couple questions that I am hoping someone can answer for me......first off, I have a '76 620 with an L20, 225mm flywheel/clutch and a 5 speed out of a 280. When I recently pulled the engine to replace the rear main seal, I noticed the pressure plate "fingers" had small score marks on them and figured this was because I had the wrong collar on the release bearing. I don't have the old transmission anymore so can't swap there. Went to the local autoparts store and gave them 30501-N1600 (225mm after '74) as referenced in the chart above which referenced SKF N3052 Bearing Assembly. When I compared this new bearing to the stock one I removed from the 280 transmission, the overall height is the same, however the collar is longer on the new one.....so long story short, my question is this; Why would the collar on the new bearing be longer but the overall height the same? Does this matter? Would anybody happen to know how long in mm the collar for a '76 620 4 speed is? Or lastly am I just totally out to lunch and not understanding the concept of a release bearing?? Thanks in advance!
