R32 AIRCON PULLEY BEARING.

Puller plate info:

Flat bar 50 x 6.

3 - 6mm dia. holes on 38mm PCD.

Photo 1. Remove the pulley centre bolt.

Photo 2. Fit M6 x 20mm long setscrew into centre bolt hole by approx 8mm.

Photo 3. Fit pulley plate using 3 – M4 x 20mm setscrews over centre bolt.

Photo 4. Tighten down on the 3 – M4 setscrews until the clutch plate rises off the parallel spline.

Photo 5. Remove all setscrews and clutch plate.

Photo 6. Remove circlip.

Photo 7. Using a 3 - jaw puller, remove the drive pulley.

Photo 8. The bearing in the drive pulley is now accessible.

Photo 9. The magnetic coil is now also visible.

10. Take the pulley to a machine shop where the peen indentations can be skimmed off with a lathe, the bearing replaced and peened in again.

11. Clean all components taking care to remove magnetised particles using compressed air.

12. Lightly oil the wick dust seal before re-fitting the clutch plate.

13. Assembly is simply step by step in reverse order.

Absolutely awesome diy grigor.

I've got a compressor on my daily driver with a worn bearing.

I'm not sure if it's just the bearing that's worn, or if the compressor is also seized though. It's hard to describe, but the 'rest' of the pulley (the bit that's inside of the free spinning part when the belt is off). Is that part meant to be turnable by hand? or is it meant to be f'ing tight?

Also, how much does it cost for the work to change the bearing? You in sydney and know anyone that does the bearing by any chance?

In addition to the bearing, if it is seized, which is the part that's seized? can that part be changed alone?

The reason why I ask, is because I have a freind who got a compressor reco'd and it was $600. Bit exxy considering i'll need to get gas, blah blah on top of that too.

      @Butters I can't tell you why but the bigger HKS step 2 cams improved low and mid end immensely. Turbos started spooling about 1k RPM less than before and the idle/vacuum was rock solid, it was an absolute thrill to drive, 3rd gear pulls hit 180kmh where previously only managed 160. Conversely, the milder poncoms in there now have a funky idle making it harder to get off the line, drives poorly in lower revs, laggy and makes less power/torque throughout. Feels better after I swapped the EBC but unless I put it on the Dyno again, I can't say how much better.

      Hi Sydney kid   do you still selling spring and blistein shocks for Nissan 260rs? Air any suspension upgrades? Please advice     yudy

      Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.

      @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.

      @Darrel It's so tempting to say e85 is borderline magic. It cools the intake charge, so if you're flirting with the edge of the turbos compressor map it helps dramatically cool down the hot air the turbos are pumping. It is very resistant to detonation so you can crank the timing, I don't really want to say you won't be knock limited anymore.... but you probably wont be knock limited anymore lol. I wouldn't be surprised if you made 20% more power swapping to e85 (provided you have the fuel system to support them, bigger injectors maybe bigger pump etc).
