APE manual cam chain tensioners are designed to replace the automatic and hydraulic tensioners on high performance engines.
The automatic adjusters can back out when the throttle is closed suddenly at high rpm.
This allows the cams to go momentarily out of time, and can result in bent valves and/or serious engine damage.
Hydraulic tensioners have a tendency to put too much tension on the chain guide under high rpm and the resulting high oil pressure conditions, resulting in premature wear.
Both problems can be eliminated with the installation of the APE manual tensioner.
No matter what the engine does, the cam chain tension will remain constant.
An APE manual cam chain tensioner is a must for any kind of performance riding.
APE manual tensioners are CNC machined from billet alloy to exact tolerances for perfect fit.
PRO SERIES
APE introduces the Pro Series manual cam chain tensioner.
This new tensioner is designed for the racer who frequently adjusts his engine.
The easy-access socket head adjuster screw is perfect for tight spaces.
The interior o’ring design ensures that repeated adjustments will not eventually flatten the o’ring against a jam nut.
APE'S Pro Series tensioner features an internal o’ring and custom-machined adjuster bolt.
The bolt is broached with a 4mm hex.
Most Pro Series tensioners come with mounting bolts and gasket (or o’ring, where applicable.)
