Subject: [Mg-mmm] Luvax rear shocks
Message-ID: <BLU0-SMTP78A6E5EA74287386E3BD992BC0@phx.gbl>

Hi Guys.,
Quiet on the MMM chat lines, so here is a question.  I have taken the rear
Luvax shcks apart for KN0389. Look like new inside. I just need to install
new shaft seals.
Question is, what grade of oil is recommended for the shocks? I see TA rear
shocks in Blower says "Shock absorber fluid ". I intend to try Motorcycle
#20 or #25 fork oil.

1972 MMM Yearbook Luvax article says #80 gear oil, seems quite thick for the
small ports in the shocks?

Unless somebody has a better suggestion.

Surprisingly the Luvax shocks came apart quite easilyy after I made a tool
to unscrew the rear cover.

KN0389 is proceeding, two steps forward, one back.

Thanks from Canada, Bob

Subject: [Mg-mmm] PB Crank Flange Removal.
Message-ID: <58985aa3a77f27e65ed19e86e845bb53.squirrel@204.14.90.12>

Hi all!

Figured I'd finish off 2011 by stripping down the PB race motor for
various reasons.

I'm working now on removing the crank/flywheel flange.  After removing the
flywheel, we noticed that the crank nut was loose.  The crank is a Phoenix
crank and there are no provisions for locking the nut.  We have a
substantial puller bolted to the flange using all bolts, yet have not been
able to get the flange loose.

What tricks can be used to break this free?  We've tried a long pipe on
the puller wrench, a large air impact wrench(trying a bigger one over the
weekend), and hitting the puller end with a hammer.

Are the flanges available if this one needs to be cut off?  I'm concerned
about the heat treatment of the taper due to the loose nut and vibration. 
Also concerned that the key has become lodged in the flange somehow.

Thanks!
Jason.

There is a bit of a problem with these flanges, in that the flange can in 
effect fret weld itself to the taper.  An hydraulic puller and a damn sharp 
tap (=clout!) with a 4 lb hammer might do the trick.  I've had this problem 
a few times on Pheonix and other close tolerance taper shafts.  Have you 
tried talking to John at Phx. about this?

I've had this problem with large waste water pump impellers that are on
tapered shafts.  The fix was to use an hydraulic puller, heat the area with
a torch, and leave for the night.  The next morning the impeller had
separated from the shaft very nicely.  I suspect the shaft cooled down
faster that the impeller allowing for the separation.  Before succumbing to
this method, I'd get ahold of Phoenix and make sure you won't induce some
serious warping damage by using heat.
