Commencal Super 4 suspension bearings

stubs

Just stripped down the suspension on my Super 4 and ordered some replacement bearings from BETD http://www.mountainbikecomponents.co.uk/

Thought I would post the sizes and quantities needed in case anyone else is thinking of doing the job

You need the following

4 x 608 rs for the rocker links
2 x 6804 rs for the left non drive side swinging arm bearing
1 x 6904 rs for the right drive side swinging arm bearing

All this comes to £31 delivered

The drive side swinging arm bearing was actually fine but the 2 non drive side bearings were knackered seized almost solid with rusty gunge coming out of the seals. All the rocker link bearings feel a bit crunchy and are on there last legs.

Thanks very much for that as I was just about to commence the same job on the same bike. As a matter of interest how long did yours last? Mine have done nearly a full year now and I was going to replace as a precaution.
PS I replaced my Scandal with the 4.2, great minds etc.

My bearings have done a year and I worked it out the other night about 2,000 miles which isnt bad for original bearings. Especially when you consider all the mud it has waded through and all the washing that entails.

Removing the swing arm is a bit of a struggle as the axle is a tight fit in the bearings I had to plane a piece of wood down till it fitted through the bearings so I could wack the axle out.

Removing the bearings from the rocker links is easy you just need a couple of sockets (22mm and 12mm I think) and a vice to press them out. The swinging arm bearings are a different matter I used an M8 nut and 75mm M8 bolt, a selection of washers (the big repair washers are handy if you can get them), a 32mm socket and an offcut of 20mm MDF .

The right hand drive side bearing came out easy using the bolt, washers and socket.

the left hand non drive side was a bit of a mare there are 2 bearings in there and they had rusted so didnt want to come out plus there is a line of weld right were you want to put the socket which means the socket is at an angle which is not good for pressing out bearings. This is where the MDF came in I cut the MDF so that I could use it as the bearing press anvil. It took a lot of fiddling with a hole saw and a file till I got it just right. When I had it right the bearings popped out easily.

I assume all this is the same on the Super 4.3 lads ?

I'll make a note of this and order in about 9 months

Little tip if you can get 'em is to go for polymer injected bearings for applications like this. Instead of grease, the entire airspace is filled with a heavy oil impregnated polymer material (so it can't wash out or get contaminated with grease etc) - not cheap but I love zero maintenance......
