Paralever bearing part numbers

[hops]

I've ordered some new bearings to go with the plethora of bits needed to get my GSA back on the road & think I've been sent the wrong parts, unless they've changed design recently.

The paralever bearings on the final drive are graduated on my bike but the new ones from motobins are a uniform size. Number 2 on the diagram

The new bearings are like this

When I saw them on the website I spoke to motobins as they look different and the doris said she'd check my order to see they were the right parts.

If they are wrong does anybody have the correct part numbers please?

The bearing in your picture is the correct bearing

FAG 10-6465A

Don't know what you mean by graduated. Push out the old bearings using heat on the casing and either a bearing puller or some suitably sized sockets and a bolt as a puller.

Heat the casing and press in the new bearings making sure the writing on the bearing faces the driveshaft.

I bet you've just removed the bearing inner race and roller cage leaving the outer race in place

Press out the outer race from the FD and all will become clear...

I've not removed anything yet except the final drive unit itself but I'm sure what was left of the bearing on show had a narrower aperture on the inside edge. Maybe I was imagining things, I'll check tomorrow when I've got some spare time. I also thought the bearings had a sloped face to allow some adjustment, a bit like the brass part in this pic?

The bearing in the picture above is one of those daft bronze bush things that the Merkins get worked up about (although the basic geometry is similar) - yours have tapered inner and outer races with a cage of rollers inbetween.

Take one of the bearings you've just received and examine it from each side. Are the inner and outer races different thicknesses on each side?

Or post a pic of each side of the bearing...

The bearings you have are tapered.
Use your thumbs and a bit of strength and you can seperate the two halves by pushing the roller section out.

Put them in smaller diameter end first.
