What blind bearing puller for small (8mm ID) four bar linkages?

As about, anyone know where i can get a small blind bearing puller to do seat stay bearings on FSR bikes?

Thanks

rawlbolt or similar. proper blind bearing pullers cost ££££

You shouldn’t need one. In between the bearings is a threaded bar that the clamping bolts screw into. Screw a long M6 (or M8) bolt into this and tap it, and it should push the bearing out. Then do the same from the other side.

Do not wang it with a hammer. Tapping should be enough.

Reassemble with lots of grease to help waterproof the bearings from the inside

^ genius!

ithankyou. 😛

This works well if you don’t want to spend too much

On a related subject I’ve got a blind bearing puller set but the collet for 8mm has bust. Anyone know where I can get a spare?

How well does the rawl bolt work?

Very well.
I used to use them for changing wheel/swingarm bearing on my MX bikes.
Drop the bolt into the bearing, tighten it up and just tap the bearing out.

Like the idea of the Rawlbolt method but can’t seem to find a Rawlbolt with the correct width for an 8mm ID bearing, 12mm seems the smallest size. Anyone know if smaller are available?

Yes – usually availbale in much smaller sizes

Pierre I emailed the manufacturer (franklin) of mine, as mine came with a bent collet, but unfortunately the answer was not cheap (for me anyways):

Part No. 19762 15-19mm BEARING EXTRACTOR 913D cost price £ 29.75 + vat – carriage paid witin the U.K

EEK! I only paid £50 for the puller…

Yes – usually availbale in much smaller sizes

Hmmm, I should have looked at not just Rawlbolt – Loose Bolts as their hole diameters are 12mm min. Still got to be pretty narrow though and the bolt itself will probably have to be M6. Time for a trip to the local DIY store.

Excellent tip Del…worked a treat: http://singletrackworld.com/forum/topic/sooooo-hemlock-owners-any-tips-to-shift-these-bearings

You can also Hydraulic blind bearings out, great for small needle roller bearings like Crankshaft spigot bearings (Where the gearbox input shaft runs on a RWD car gearbox)

Pack the void and the centre bore of the bearing with grease.
use a shaft in the centre of the bearing
Tap shaft through bearing
Shaft acts on grease
Grease being non compressable, forces bearing out from behind ;o)
No risk of damage that way either 😉
