Paralever bearings

[roddy]

Hi folks

I recently got a 99 GS11 with 47K miles and was going round the usual things just checking it out.

I suspect my paralever bearings have a slight amount of play in them about 1mm of movement at the back tyre when you hold it at 12 and 6 and try to wobble it, with the rear brake on this movement is still there, this is why I suspect these bearings.

my questions are

1. is my thinking right ?
2. if so, is this amount of play ok ?
3. if not, I read in another thread you can adjust these bearings, how do you do that ?

Cheers
Roddy

Steptoe told me on ADVrider still have not done it yet (Scared).

Adjust them - you don't even have to take the wheel off.

30mm socket on an extension bar, through the spokes, undo the lock nut .

Adjust the pivot with a 12mm allen key, on an extention bar - re-tighten the locknut to torque value - 5 minute job

Unless the bearings have broken up

There shouldn't be any play at all. To be honest the chances are the bearings will be grooved if the bikes been run for any length of time with play in the wheel. New bearings are £14 ish each and take about an hour to fit if you have the right kit so it's not worth pissing about hoping the surface isn't shot. My Adventures had play in them at 4K so I fitted new ones as a matter of course.

The dirt may've penetrated them too by this time, so they may be worn. Try to retighten them, it's easy if you don't want to remove them.

The trunion and lock nut are held by locktite 270. You should heat the area to 100 degrees C with a hot air gun before trying to turn the trunion. You are then meant to remove the trunion and clean off all the old locktite from the trunion and the swingarm itself, before reinstaling the trunion with new locktite and preloading to 30Nm then backing off before setting at 15Nm.

Some people don't do this properly and thats fine, but it does matter to the handling and the life of the bearings. Too tight or too loose will cause accellerated wear and poor handling (most noticeable riding along white lines/ cats eyes etc)

There is also a risk of rounding out the 12mm allen key socket in the trunion if it is forced because the locktite is still hard.

cheers for that advice skydiver

I'll look out the heat gun, I assume the localised heat won't do any damage to the surrounding area.

do you need to drain the oil from this area before applying the heat ? (sorry dumb question but new to this engine)

Replaced my Paralever bearings yesterday. Heat gun is good, no damage to paint on the bevel box etc. No need todrain the oil as long as you keep the bevel box reasonably upright at all times.

While you're in there, lever the UJ out of the bevel box & lube the splines as well as the splines on the end of the drive shaft.
