Are you looking to put a new Harley chain conversion kit on your belt driven bike? Or are you worried about your sprocket or pulley mounting bolts coming loose or shearing off while riding?
Maybe not, but you should be! Stories and photos of sheared sprocket and pulley bolts abound on the internet. Once they start to loosen, the hammering of acceleration can break a bolt, and once it starts, it happens FAST.
Well, you have come to the right place friend. Hugh's HandBuilt 100% bolt-on (no fabrication required!) Sprocket Lock System was created to solve this issue and put those fears to bed.
These American made HHB Sprocket Lock Systems feature a two-piece ring that fully secures your five sprocket or pulley mounting bolts, ensuring they will not loosen while riding. They come in two finishes, tumbled raw aluminum or black anodized. These will work with all Sportster, Big Twin and Tube Frame Buells.

In this video Tim Fiorucci walks you through how easy it is to install Hugh's HandBuilt Sprocket Lock System on The Saturday Sportster 1. This off-road machine needs a beefy upgrade to ensure those sprocket bolts never back up and this sprocket lock system is the ticket. A super easy install and an inexpensive piece of insurance for any Harley-Davidson motorcycle.
HOW TO INSTALL HHB SPROCKET LOCK SYSTEM IN 6 EASY STEPS
The HHB Sprocket Lock System. We chose the black anodized to run on the Saturday Sportster since most of the bike is black already.
STEP 1: Install the back plate of the Sprocket Lock System onto your wheel.
First things first take your rear wheel off your bike and remove your 5 sprocket or pulley bolts. If they are crusty or in bad shape you will want to replace those. With the HHB Sprocket Lock System you will no longer need spacers. The back plate takes the place of the spacers. Remove the 5 button head bolts from the top of the Sprocket Lock and place the back plate onto the wheel, lining up the 5 holes.
Remove the top plate with the 5 button head bolts and place the bottom plate onto the wheel.
Line up your 5 large holes on the back plate with your sprocket and wheel holes.
STEP 2: Install your 5 sprocket bolts.
Install your 5 grade 8 bolts into the back plate, sprocket, and wheel. Remember to use Blue Loctite.
This is a good time to update your hardware if it is crusty. Remember to use Blue Loctite.
Evenly draw each bolt down in a star or criss cross pattern.
STEP 3: Torque down the 5 bolts to factory specifications.
Once each bolt is evenly tightened down, break out that torque wrench and get to torquing. Torque down each bolt evenly in a star or criss cross pattern. Start at a lower torque setting and do all 5 bolts evenly, then do the actual torque spec for all 5 bolts evenly. The book recommends for this year (2003 Sportster 55-65 FT-LBS). Always check your workshop manual for the proper torque specs for your model!
Break out that torque wrench.
Torque down each bolt evenly at a lower torque setting before doing the actual torque spec.
Use a star or criss cross pattern to torque down each bolt evenly.

STEP 4: Install top plate of the HHB Sprocket Lock System.
Take the top plate of the sprocket lock and align it to match your 5 bolt heads. You may have to spin this in a circle to get them to align properly and or you may have to torque one or two bolts a little more to get everything to line up. If they still won't line up, you may consider removing 2 or more bolts and switching their hole locations and try to line up the plate again after re-torquing.
Putting the top plate into position. You may have to rotate the plate to align the holes to fit over the sprocket bolts.
In our case, this one bolt on the right was just a little off and not allowing the top plate to align and sit flush. We ended up torquing this bolt just a little more to get it to align properly.
With that bottom bolt torqued a little more, the top plate fell on perfectly and was flush with the bottom plate.
STEP 5: Install the 5 button head screws into the Sprocket Lock System.
Now that the top plate is aligned with the 5 bolts and sitting flush on top of the bottom plate. You can now install the 5 button head screws into the smaller holes of the top plate. Use Blue Loctite and firmly secure these down. No torque spec on these, just make sure to evenly draw them down in a star or criss cross pattern.
Use Blue Loctite and install the 5 button head screws into the top plate.
Tighten down evenly in a star or criss cross pattern.
Important - Star or criss cross pattern when tightening these button head bolts.
Step 6: Reinstall your wheel onto your bike!
Boom thats it, your sprocket is locked on for good. A slick looking part, and a invaluable piece of mind knowing those sprocket bolts are secure and never going anywhere. Get your wheel back on your bike and go for a ride. Woohoooo!
Looks like its always been there.
A dope part that keeps you riding safe!
