New Product: Triumph Twins Camshaft Bushing Reamer Kits
Replacing camshaft bushings on a vintage Triumph twin is a very simple task to achieve
With some basic tools (MAP gas, drift and mallet) you can successfully remove and install new cam bushings into your vintage Triumph twin
Sounds simple right? - not quite
When replacing and installing new bushings you must make sure that the opposing bushing is inline and properly sized slightly larger that the camshaft journal of the cam that you will be using
Cam bushings are usually made undersized and must be sized after installation using a hone or reamer
Failing to line ream or hone your bushings could cause premature engine wear or worse yet.. engine failure
How can you prevent engine failure?
Engine failure can be avoided
Unfortunately, sometime things do happen, however, don't let a missed step be the cause of your engine failing
We now sell a new camshaft bushing tool kit below which will allow you to ream and properly size your fresh camshaft bushings
