Gates Strap Wrench
The Gates Strap Wrench is a high-quality tool for removing 9-spline and Bosch sprockets simply and efficiently. Gates recommends its own sprocket wrench, because typical oil-filter strap wrenches are not recommended on sprockets.
Why choose this tool?
Made for sprockets. A wrench designed for Gates sprockets, not a general oil-filter wrench.
9-spline and Bosch. For removing 9-spline sprockets and Bosch sprockets.
Simple removal. An indispensable aid for simple and efficient removal.
Never use the belt. Never use a belt as a strap wrench or chain whip – use this wrench instead.
Why a special wrench?
Gates says its sprocket wrench is made for its sprockets and that typical oil-filter strap wrenches are not recommended. The Gates belt must never be used as a strap wrench or chain whip.
Fitting and removing sprockets
The Strap Wrench removes 9-spline and Bosch sprockets. For fitting SureFit sprockets use the SureFit Tool, and for the S550 sprocket lockring the Locknut Tool.

Frequently asked questions
Can I use an oil-filter wrench instead?
Gates does not recommend typical oil-filter strap wrenches for its sprockets; it recommends its own sprocket wrench.
Can I use the belt as a wrench?
Never. Do not use a Gates belt as a strap wrench or chain whip, and do not pry on it.
Do I need special tools for a belt drive?
A belt drive needs far less than a chain, but the right tension and alignment matter. Gates offers tools for checking tension, checking alignment, fitting sprockets and protecting the belt – see the table above, and ask us which ones suit your bike.
