A maintenance guide for loose bearing wheels that were thankfully on theier way out in the not too distant future. It may look like just an illustration, but they provided an address to order bulk copies of the flyer. Looks like they used stamped and fabricated Bahne trucks as the model. The Pacific International Skateboard Association (also called Pacific Skateboard Assoc ) was the first organization of skateboard manufacturers.

MAINTENANCE and ADJUSTMENT of your LOOSE BEARING WHEELS

For safety and performance, your loose bearing wheels need periodic cleaning and maintenance. First, the wheels must be removed and set aside because some common household solvents may damage, or dissolve the Urethane and plastic parts of your wheels. As you remove each wheel hold your skateboard or truck over a large bowl or bucket to catch all the small parts and so none of the bearings are lost. After removing the lock nuts, D-washers, if used, outside race cone nuts, and bearings,set them aside to soak in a small container of solvent or cleaning fluid. Using a paper towel, clean the metal races in each wheel. Also clean the axle threads and the inside race cone nuts still mounted on the truck. It is inconvenient and unnecessary to remove these parts for routine maintenance.
After cleaning and inspection of all parts, re-assemble and adjust your wheels. First, make sure the inner race cone nuts are firmly adjusted; locked in position against the axle housing. Then re-assemble one wheel at a time as follows: Place the wheel on the axle, without bearings. Install the outside race cone nut on the end of the axle – leave it loose. Now hold the truck so that the axle is up side down and wheel you are assembling is on the bottom held on by the outside race cone nut. Drop eight ball bearings into the metal race of the wheel. Press up on the wheel to trap the bearings between the inner race cone nuts and the metal races of the wheel. Carefully turn the axle over and drop eight more bearings into the outer metal cone race of the wheel. Now adjust the outside race cone nut just enough to stop the wheel from spinning freely. Now install the D-washer, if used, making sure that the concave side of the washer is against the race cone nut. There is a slight arc to this washer – if the concave side is not against the race cone nut, your wheels will be difficult to adjust and will not hold their adjustment for very long. Now install the outside lock nut just enough so that it is snug against the D-washer. Then use your socket wrench or skate wrench to back up the outer cone nut and lock it firmly against the D-washer and lock nut so that the wheel spins freely and true. With a little practice you should find a quick and effective way to adjust your loose bearing wheels. Repeat the process for each of the other wheels and you’ll be ready to skate.
