icewtr Posted October 18, 2011 Share Posted October 18, 2011 So i was in the junk yard sunday and came across a 1974 260z 2+2 automatic. I was searching for another r200 so i looked under this car and I havenever seen this diff or the half shafts before. It had 5 bolts holding in the shafts to the diff and a u joint righ on the piece coming out of the diff. Does anyone know what diff that is. Looked like an R180 but the safts didnthave 4 bolts holding them to the diff. Quote Link to comment Share on other sites More sharing options...
zcarnut Posted October 18, 2011 Share Posted October 18, 2011 R180 from the 4x4 Nissan 720 truck? Quote Link to comment Share on other sites More sharing options...
icewtr Posted October 18, 2011 Author Share Posted October 18, 2011 Yeah that looks like it other than a different stub out of it for half shafts. ? Quote Link to comment Share on other sites More sharing options...
beermanpete Posted October 18, 2011 Share Posted October 18, 2011 The 5 bolts are likely the bolts holding the bearing cover on to the differential housing. All the R180s are like this. The early cars have "bolt-in" output shafts that use a long bolt through the center of the output shaft to hold the shaft in. These versions also have companion flange with 4 bolts that are used to attach the drive axel to the output shaft. The late 74 260Z (mid-year change I think) eleminated the companion flange, the 4 bolts, and the long bolt through the center of the output shaft. The output shaft directly holds the u-joint and snaps into the differential. The "snap-in" type have a spring clip near the end of the output shaft that interfaces with a groove in the side gears (inside the differential). I believe the splines are the same on both types but due to the difference in how they are attached to the differential they cannot (should not?) be interchaged.
