1985 Ski Doo Grand Luxe L/C: looking for help on repairs

Post by GDMCH » Sat, 22 Nov 1997 04:00:00


I have an 85 Ski Doo Grand Luxe with a 521 L/C, single carb. motor.  I ripped
everything out of the front (engine, gas tank, etc.), cleaned it off, and am
putting it back together.  I have a few questions:

1.    My y-pipe and muffler have hairline cracks on them.  The muffler was
brazed once before and I think the new cracks resulted after the brazing and I
doubt it will hold if I braze it again.  I was told that a new muffler was
$350-500, which is unreasonable considering the value of the sled.  I cannot
find a used one anywhere and none of the dealers seem interested in seeing if
something else might be compatible.  I am going to look at some decker pipes
for a 521 tomorrow, but this is a twin pipe as opposed to the single pipe that
came on the sled.  Will this work? Is this a major effort to convert if the
pipes do fit?  Also, I would appreciate it if one of you sled heads knew of a
compatible muffler that was more reasonable in terms of price.

2.     I reinstalled the engine (still looks new!), carb, fuel pump, fuel
lines, etc. and now I am reinstalling the oil reservoirs (2) and hooking the
oil lines back up (I only disconnected the lines to and from the reservoir, not
the ones that are from one part of the engine to the other).  How do I bleed
the oil lines and start it up again without harming the engine?  Also, why do I
have 2 reservoirs on this?

3.     How do I know where the chaincase oil level is supposed to be?  The
filler cap has no dipstick and I don't see any oil level markers on the outside
of the case.

Any info. on these topics are greatly appreciated

Gary,
I'm far from an expert on sleds, but have a few thoughts for you...

For item #1: Have you tried Al's snowmobile parts warehouse in Newport VT?
(802)334-7239.  These guys have yet to not have a used part for just about
any machine (from everyone I talk to).  And they will ship to you (ups takes
1-2 days). Also, you might try Poor Farm Trading Post in Townsend Mass.
(don't have the phone number for them... try information 1-508-555-1212).

For item #2: Ask someone else on this one, however, mixing oil with your
first tank of gas might be a good precautionary measure!

For item #3: I think you fill up the chaincase level until it comes out of
the filler hole... again check with someone more knowledgeable than I...

Empty the chain case and replace with one small bottle of chaincase oil
(about 6 ounces). If it's like my machine (88 Safari 503) the chaincase
should be almost identical.

 YIKES !!!!!   NO  ,  NO, !!!    #1 /   Yes, try a wrecker as
mentioned for the exhaust problem .  
 .. #2 )   The  " Other "  oil tank is the one for lubricating the
Rotary valve intake .
 #3 )   No NO No,  DON'T  fill your chaincase to the filler hole !!!!!
  Use the small bottle from your dealer or fill it till it is about
halfway up on the bottom sprocket . If there is no plastic windo to
look, use a piece of straight stiff wire to slide down to the bottom,
pull it out and lay along side the chaincase to see the level.

This is not true at all and don't do this, otherwise you'll blow up you're
chaincase!   CHaincases are only suppose to have 1 -2 inches *MAX* of oil in
them. Just enough to keep the chain oiled...  Overfilling will cause a huge
build up of pressure when the oil expands and you'll blow all of your seals
and it'll end up costing you big bucks...
Use 80W90 Extreme Pressure Gear lube or whatever you're manufacturer calls
for..
