8" Wheels

Blue Loctite (McMaster P/N 1004A12) is recommended on all bolts that thread into a tapped hole.

Step 1

Slide Pneumatic Wheel Hub Adapter onto the Pneumatic Wheel Hub. Align the slots for the tube stem in both components.

Once the hub adapter in installed, rivets may be installed to hold the adapter in place. The recommended rivets can be found on McMaster (P/N 97519A098).

The hub does not need to be riveted to the hub. The wheel will still function without the rivets.

Step 2

The Pneumatic Wheel Hub will com with the screws and cover plate pre-installed. Before attempting to install the tire onto the hub, the cover plate needs to be removed.

Be sure that the tube is in the tire before trying to put the hub in the tire.

The tire will be a tight fit onto the hub. In order to help with installation, spray the area with a soapy water solution where the tire and hub contact each other. This should help the tire slide on much easier.

The stem in the tube needs to go through the slot in the hub. Also it is recommended that the stem faces towards the cover plate to make filling with air easier.

Simple Green is the recommended spray to use.

Step 3

It may be hard to get the tire to sit fully on the hub due to it wanting to spring back off.

Once the tire is on the hub as far as possible, get all six #8-32 bolts started. Work around the cover plate and tighten each bolt a little at a time until all bolts are tight.

Be careful not to have the tire pinched between the cover plate and the edge of the hub.
