I'm replacing the rear wheel bearings on my 1984 XR500R (maybe this should be in the vintage forum?). The Clymer manual says that a special tool is needed to remove the wheel bearing retainer on the left side of the hub. It shows Honda PNs 07910- 3000000 (wrench body) and 07710-0010100 (wrench "A"). The diagram shows a couple screws going through the wrench and into opposing holes on the bearing retainer, then you unscrew the retainer from the hub like a bolt. Anyone know about this? Can the retainer be removed safely without this "special tool." I'm riding with buddies this Saturday, speedy responses will be much appreciated!
