Chain and Sprocket Job

[Mustang]

Time for chain and sprockets for Mrs.Mustang's Steamer ...............

1. You will need the following items :
    Torque wrench
    assorted spanners and sockets
    New front sprocket  (Sprocket specialists  in CA 30 bucks )
    New Chain  ( Dennis Kirk  approx 100 bucks )
    New Rear Sprocket ( Dennis Kirk has JT steel rear sprocket for 60 bucks )
    A chain breaker and rivet tool for the new master link .
    4 quarts of oil and a new filter



2. Get the rear wheel off the ground .

This works and of course so would a center stand


3. Drain the oil and put the new filter in while you are down there .



4. Remove the left side footpeg / kickstand bracket . The big Torx bolt has a nut on it , you need a 19mm box end and reach up by the rear shock .


Look at the rust on this chain it was time !

5. Now you can remove the shifter and pull out the three bolts holding the slave cylinder to the sprocket cover . Gently pull the slave off and let it hang out of the way .  


6. Now remove the sprocket /oil fill cover . Now you know why we had to drain the oil !



7.  Have your lovely assistant stand on the rear brake pedal while you use a 36mm socket and remove the sprocket nut  ( yes they are super tight usually )



8. stuff a rag in the crankcase and clean off all the crud , doesn't have to be spotless or pretty just get rid of the road grime and built up chain wax or lube .
As you can plainly see , Mrs. M doesn't use that PJ1 in the first photo very often .
That's why we're doing another "chain job" already  

Now would also be a good time to check or replace the swingarm chain slider and the rub block .
9. Using the motion pro tool break the chain (or remove the master link ) most chains will be "endless "

10 .  Remove the rear wheel and install the new sprocket . Then put the wheel back on .


11 . Now unless you bought a chain that was 114 links make your 120 link chain be 114 links , using the chain breaker .  Install the new chain and use the rivet master link that came with chain and your motion pro chain riveter .
assemble the rest of the bike the reverse of disassembly and adjust your chain , should be about 1 1/4 inch free play with wheel off the ground .
Have a cold one , you are done , and it only took about three hours .
Don't forget to fill it back up with oil . in a week or so check the chain tension and adjust if needed

Not sure why you have to do all that work...can't you just pop the front sprocket cover off and slip the new one on???



 

(I think if she's going to let you do maintenance on her bike it's only fair that she let you modify it!!)

Nice write up, btw - thanks!

Nice tutorial.  I just changed mine and used an EK Sport Quadra 530SRX X-Ring Chain that came in 114 Link version for $95 from bikebandit.

But I reused the gears (I know, I know) and it turned out that I had to cut the chain down anyway because the gears on the bike weren't stock.

Could you just lay the bike down on the right side so you wouldn't have to drain the oil?  Just curious.  I'll do it the way you said as it is time for an oil change anyhow.

Thanks for taking the time to write a How-To.  I linked this thread to Steamer Wisdom.

Absolutely , you can do a sprocket job and save the oil , just plug up the hole in the crankcase with rags to keep 'stuff' out !

Doesn't have to be leaned over much either .



My Steamer getting chain and sprockets in Los Angeles , CA right in the middle of a road trip ! :shock:

Hey Mudhen..

What sprocket cover did you use and could you tell me a bit more about the cover mod, that looks slick..

Cheers,
Greg

Crazy Ted....
I thought you dropped out of Tigers about 3 years ago ....

Glad to see you're still around....

[CrazyTed]

Yeah, I got hit by a drunk driver at work and wasn't able to ride for a long while.  I'm back now although I'm dreaming of a Rocket 3 Touring edition.  The old Tiger is still going strong although I'm hearing weird noises from the drive-line so I'll be pulling the cover off.  Guess a chain and sprockets will be coming soon.

[CrazyTed]

Well, what a surprise.  Leaned the bike over and took everything off.  The front sprocket looks almost new still.  Come to find out the bottom chain slider is gone and the chain is running on metal.  Makes me feel better.

I used an XRs Only cover for a CRF450.  Hmm...that company name doesn't seem to fit them anymore.

Just used my dremel and cut the cover apart.  Cut around the clutch pushrod part, and cut the sump piece off.  Then I used a really cheesy rubber push plug in the sump hole and made up a little bracket that bolts the CRF cover to a now-unused top hole for the old cover.

I'm no Mustang I'm afraid...it's an extremely cheesy hack job...like the rest of my 'mods'.  But it allows me to switch between my street 19/48 setup and my off road 16/53 setup without having to drain the oil or take off the footpeg bracket...

Just take a metal saw and cut that damn sprocket cover in two parts.



You will need some liquid metal to close the hole of the oil filling funnel.



And while you are just handling with a saw: How about a little window to easily control the sprocket wear?



After that you will only have to do four screws to access the sprocket.



Fell free to copy...

Fer!

Stupid Germans always make stuff look so easy.

:lol:

I've got a spare cover...I may take you up on your offer and copy that!!!

[CrazyTed]

Man, it's so simple it's perfect....
