Volvo Maintenance Hints for 7xx/9xx - Bill Garland's Nuclear ...

at the local import auto parts store for ~$125. You'll need a puller tool to get the clutch off. The K-
D one for GMs works, and can be borrowed or rented at some auto parts stores. Note, this is
not an ordinary 3-arm type puller. Otherwise the swap is straightforward and leaves you with a
new clutch plate as well. [Another Response:] There is a special tool (naturally) but it just
pushes it off by attaching to the threaded fitting in the hub of the face of the clutch. Once that is
off, there is a snap ring at the front which holds the pulley and bearing on. Tapping on the pulley
will slowly move the assembly off the front of the compressor. Then there are 3 Phillips head
screws which hold the coil on to the front of the compressor. These round off easily so try
tapping on them with a 3/8" #2 phillips bit before trying to turn them.
Clutch Sources. [Tip from Rafael Riverol] Clutches alone may be had from www.
hancockindustries.com. Most suppliers sell only the complete compressor with a clutch.
Rebuild or Replace A/C Compressor?
Diesel Kiki Models. [Inquiry] My '87 700 has a Diesel Kiki a/c compressor that has seized. Is it
rebuildable (by me?) or smarter to just remove & replace? Are rebuilts available? Are they good
as new? [Response: Tom Irwin] In the years I worked in aftermarket I probably bought between
50,000 and 100,000 Diesel Kiki's, as rebuildable cores. What can I tell you... Well, in general
they are CHEAPLY built and not very reliable compared to Nippon-Denso, Panasonic, etc. "Is it
rebuildable (by me?)" No. "Are rebuilts available?" TONS! EVERYWHERE! "Are they good as
new?" Sometimes they are better...the aftermarket KNOWS which components fail and
endeavor to improve the unit. Look for who manufactured it... Murray/Moog, Four Seasons, AC
Plus, are all EXCELLENT rebuilds. ASK the parts guy who makes their private label stuff "Can
the clutch be replaced without discharging the system?" Yes. One last note... Diesel Kiki's, that
were converted to 134a are shit. Since you are going whole hog... get a 134a pump...new
receiver/drier... do it right. 12 is just too much hassle. [Response: Lamar] You can get a new
one for just over $200 at Autozone or Advance. They come ready to use either R-12 or R-134a.
I just replaced one on an 88 740.
