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.

    • 12+ months passed so they have no obligation to do a warranty claim. It leaked from the rear circuit. Front circuit was fine, but I tried many times to bench-bleed and in-car bleed (wasted 1L of Penrite racing brake fluid) to no avail. Threw my old BM50 or whatever the standard R32 GT-R BMC is, brakes went back to normal. So from my very limited anecdotal experience, I cannot recommend HFM, even though a lot of their products looks good. Just my experience (I have a genuine Nissan BM57 in a box waiting to be installed now).
    • How dare you sell your unreliable Skyline and buy a reliable, Toyota/Yamaha car with a strong gearbox, torsen LSD and Toyota reliability. At least you won't need to worry about oil pumps, big catch can, oil restrictors, blowing off power steering belts, sheering off 3rd gear, failing ABS relays/pumps, etc.
    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/
