qd wheel bearings

[I Rea]

Hi have dismantled the rear wheel on my mk2 sq 4. Removed the brake drum and combined sprocket. Wheel bearing in brake drum. On the timing side there is a bearing. On the drive side of the wheel should there be another bearing. I found a bearing retaining ring behing there is no bearing but there is a spacer that looks like it is there to locate a wheel bearing.

There are only two ball bearings in the whole rear wheel/brake assembly.
There are two spring steel retaining rings. A small one which locks the brake side, stub axle, into the brake side ball bearing; and a larger one which locks the brake side ball bearing into the brake hub.
There should be a grease retainer between the larger ring, and the bearing. Cheers, Chris.
