Lower bearing fitting: loctite or grease ?

leszazas · Jun 15, 2011

Hello, I'm changing my lower bearings on my Tracer VP as I received a new warranty swingarm. By the past I have put some Loctite (the one made specialy for bearing fitting) and heat with a heatgun when removal needed.
But what is Intense policy ? Shall I grease them instead so maybe they can sit in place easily ? Maybe Loctite put to much stress on them as the bearing or "blocked" in place ?

Any advice will be appreciate !
Thanks

Hi,

You shouldn't need the Loctite unless the bearings are a loose fit, which they shouldn't be. I normally put them in as they are, as most bearings will have a light coating of oil or grease to stop them rusting anyway.

I wouldn't dream of putting a heat gun anywhere near any of my bikes either!

I have a quick question, how did you get the old bearings out? i need to replace some on my parker and dont want to damage the frame or anything, is there a pecific way or an easier way than just brute force?

To dismount the bearing I'm using a tool called in english a "blind bearing puller". It expend INSIDE the bearing and has a weight on it to pull out the bearing FROM IT CENTER. I don't like to PUSH OUT the bearing from the inside with something like a small tube or screwdriver because you are putting alternative pressure (on the left, the right, up and down) and your bearing come out of the frame unsymetrically which can damage the frame bore hole.

I finally decide, after receiving an advice from Intense staff who I here thank greatfully, to use just a drop of bearing loctite in the bore of the frame itself.

As I see it, there's a tremendous amount of "bending" forces apply to the lower link to resist lateral flex from the rear of the bike and as the width of the the lower link is small (and the bearings too are small) the bearing would naturally like to pivot in the frame bore. Of course the pivot axle should prevent this beacause it put lateral pressure on the bearing, but loctite will help.
Heat gun require to dismount, but without any problem

Santa Cruz recommends loctite 680. I just did mine and used nothing. They should fit pretty tight and shouldn't move.

I just used a screwdriver from behind. I really needed to whack the crap out of them to get them to budge. I wouldn't recommend that if you need to re-use the bearings, but if you are replacing them, whack away. Just be careful that your screw driver doesn't slip and gouge the frame. It sounds barbaric, but it worked fine, and I know others do it this way as well.
A blind bearing puller is better, but they are pricey.
