Your Generel Over All View Of The Tensile Freewheel

Recommended Posts

You have to service Enos more often than open bearing freewheels usually just because the grease from the sealed bearings tends to ooze out onto the pawls, 'specially if you lube the pawls with a spray-lube such as GT-85. You basically just clean it all up and check for any cracks or problems with the pawls. With high engagement point freewheels, the ratchets tend to be shallower, meaning that you're basically putting more pressure onto the pointed tip of the pawls. I've sheared a few Eno pawls in the past 'cos of this, so checking it out every once in a while is a nicer way of finding out than having an almighty skip and then hearing the Grind of Death from the freewheel chomping through the shards of metal in there.

To service it, you simply take the crank arm off your bike, undo the lockring, remove the upper set of caged bearings, lift the driveshell off and then you're left with the pawls, springs and the lower caged bearings just sitting there on the freewheel body. Take them off, give them all a wipe down, lube it up with either something simply like GT-85 or maybe Finishline wet lube on the pawls and springs, then reassemble it. Getting the driveshell back on and holding the pawls down can be tricky, so I usually find that placing the little shims that sit underneath the lockring on top of the pawls and springs (so they're held in their carriers so they don't pop up and out), slide the driveshell down, then just use an allen key or screwdriver to push each pawl under the driveshell until you've worked it all the way round.

It sounds hard, but when you're actually doing it it's really straight forward.

You don't need to do it that often, at all. If your freewheel makes any funny noises it's usually best to just strip it down and give it a once over, but like I said, with an open bearing freewheel you don't really need to do it all that often (Y)
