Thanks for reading,I have a gardiners slx22 that I use on a daily basis approx 6 hours a day,the pole is seven months old.
When do you need to change the shims ?
What are the benefits of changing the shims ?
Advice appreciated as I want the pole to last
Many thansk
There have already been many good replies to this thread
From a mechanical point of view the shim helps reduce friction on the action of the levers and reduce surface wear on the cam on the lever and the cam bed on the clamp body. It does not actually improve or affect the clamping action of the clamp on the section below.
Why do we have these shims on the clamp mechanism as no other mainstream clamp has them?
This is because they help keep the movement and action of the lever arm smooth and easy during the whole life of the pole. A modern pole/clamp body can stay in service for 3-4 years and so will attract a lot of wear. This will show as grooves worn on the lever cam and the cam bed on the clamp. This negatively affects the smoothness and ease of actuation of the lever. These self-lubricating shims keep the action as easy as possible for as long as possible.
Why change the shims?
On a clamp where the shims are wearing replacing them will restore the ease of lever actuation which will improve the feel and use of the clamps. This can quickly restore that 'new clamp' feel to older clamps.
What it will not do is improve the clamping strength of the clamp any more than adjusting the bolts up would. However with worn clamps adjusting the clamps up tighter without replacing the shims will result in stronger action but the levers will become progressively harder to operate which will negatively impact your interaction with the pole.
Whilst it is not essential, replacing the shims every 6-8 months will make the clamps easier to work with.
