I'm replacing the stock front sprocket for my 91 chain drive
sporster. Unfortunately I can't get the sprocket nut off.
I've tried WD-40, liquid wrench, a propane torch, and animal
sacrifices to God -- but to no avail. I estimate that I've
put at least 300-350 lbs torque on the thing. Is this normal?
Do I need to start working out at the gym? Any suggestions?

And yes, I *am* turning it the right way.

Thanks in advance for your help.

Hi Daryl

I just removed mine not long ago and it was from a 93 Softail. I
take it that you are referring to the compensating sprocket inside the
primary chain unit. All I did was to use a power impact wrench I rented
for $20 and it came right off. I tried to turn it by hand but it did not
work because I already had the wheels off so I could not lock it. The
front compensating sprocket has to normal right turn threads unlike the
mainshaft nut inside the clutch which had the left hand threads. I also
removed that mainshaft nut the same way by just reversing the power inpact
wrench.

Actually I was referring to the front sprocket for the *rear*
chain. An impact wrench will be my last resort -- I guess
I was wondering if there was any chance of doing it by hand
and saving the 20 bucks.

Thanks

Well, they do make a special tool for this thing. It costs about $25.
Before I had this tool I used to 1) make sure you got the lock washer
ears bent back. 2) Used a hammer and a punch or chisel on the flat of
the nut to beat it off. A chisel will give you more leverage but you will
have to replace the nut when you are done.

This tool looks like a mushroom. Its got a long hollow shank and the
wide end is flat and looks like a real shallow socket. The whole thing
slips over the mainshaft of the tranny and then over the nut. You got
to leave your rear drive chain on. An impact wrench will work much
better than the breaker bar that comes with it. You can get this nifty
tool from you friendly HD dealer or go to an independent shop and
get one from Drag Specialties. If you get this thing you will have a
lot of new friends.

I had the same problem with a '92 sportster. I rented a 3/4" drive rachet
wrench and a 1 7/8" socket. After blocking the rear wheel to keep the bike
from rolling backwards (the front sprocket of the drive belt is reverse
threaded) the nut came loose after I sat on the bike to get leverage. Maybe
putting on that Locktite 271 was not such a good idea after all....

my friend's '90 has a tiny socket head screw used as a locking device next to
the nut, did you remove it (assuming you have one on yours) ???

I changed my front sprocket and had no problems at all getting it off.
Has it been removed before? if so did they lock tight it maybe.?
Guess I've been lucky on my bike.
I have the tiny socket head screw used as a locking device next to the nut as well.
I did locktight (blue stuff) that when I put it back on.

In my repair manual they recomend loctite 271 (red) for the nut
itself (if memory serves). Since the nut is torqued to a max
of only 150 lbs I'm assuming that they loctite it from the
factory.

In any case, it doesn't matter anymore 'cause I wheeled the
bike down to the local auto repair shop and gave the guy $5
to knock the nut off with his air wrench. No problem.
Should have thought of that a long time ago.

Thanks for the replies

Ack! If you're going to use Loctite on an application like that,
use 242 (the blue stuff)!!!

271 (the red stuff) is for interior engine bolts (rod bolts, for
example) that you don't want coming apart on their own no-way, no-how. You
have to heat the parts with a torch to make 271 give up.

Then there's the green stuff, which is intended for stuff that NEVER
gets disassembled.

I think your memory is faulty. Why on earth would they use 271 on
the nut itself if they're already putting a setscrew in there and loctiting
THAT?

That's how I got my compensating sprocket nut off when I redid
Red's primary, except the gas station guy did it for free. ;-)

What is the correct Loctite to use when attaching a timer rotor
to the end of the camshaft? The service manual says to use
Loctite "Lock and Seal" but I've never heard of it. What is
this stuff?

Loctite Retaining Compounds
- ---------------------------
Notes:

+ The gap fills are all *maximum*. According to the guy at Loctite when I
asked these very questions some time ago, the optimum gap is between 0.001"
and 0.002" (0.002 to 0.004 diametral) for any of theses adhesives.
+ This table refers to the *retaining compunds*, not *threadlock compunds*
+ The viscosity "Low/Med./High" is from the descriptions for each product
+ The '660' is referred to as 'Quick Metal', considered a non-running product
+ If you're using another brand (is there any other ? :) you're on your own.
+ Cure Speed assumes no accelerator is used. Activators/accelerators may
improve the gap filling capabilities slightly as well as ensuring proper/
faster curing respectively. If you need to accelerate it, talk to your
dealer; I don't have any specific numbers.
+ Primers are useful on inactive surfaces such as aluminum, black oxide,
stainless steel and thermoset plastics
+ Remember... *CLEAN CLEAN CLEAN* !!!
