wheel bearing lock-rings

gortnipper · Jan 6, 2016

I need to find/make a cheap pin spanner to get these off in prep before I pull the wheels. Can someone let me know the diameter and spread of the pins that I need to fit these? I assume the rear and front wheels use the same wrench, even though the lock-rings are different p/n?

Thanks.

Any bearing shop will have for sale an adjustable tool for this purpose. Not expensive.

4mm pins work??

AMF 764AZ-18-40x4 Pin Wrench 41004, hinged, blued, for nuts with 2 holes, with 4mm pins. Working distance between the pins is 18mm-40mm. 150mm in length.

Or 3mm?

Hook wrenches are not correct for the lock rings, its the pin wrenches further down that are needed but at $62.50 the factory tool or an adjustable wench drilled for pins is way cheaper.

Or this from a US seller

Harbor Freight has an adjustable pin wrench for grinder and saw blades. Works great and < $10

4mm is 5/32, and I can get one of the grinder wrenches here in NZ for 5.50. Just need to be sure that pin size will work?

The stock cap holes measure a bit over 6mm.
EDIT (sorry, this measurement is for the disc brake caliper)
