> **2d8.** Explain skateboard maintenance (cleaning, adjusting bolts, and replacing parts).

A well-maintained skateboard is safer and more responsive. Your counselor wants you to explain the three maintenance areas: cleaning, adjusting bolts, and replacing parts.

### Cleaning

**Bearings.** Bearings collect dirt, dust, and grit that causes grinding and slows wheel spin. To clean: remove wheels, pop out bearings, remove rubber shields if present, soak in a dedicated bearing cleaner or isopropyl alcohol, agitate to loosen debris, air-dry completely, and apply 1–2 drops of bearing oil before reinstalling. Never use WD-40 on bearings — it is a solvent that strips lubrication.

**Grip tape.** Grip tape loses effectiveness as dirt builds up in the abrasive surface. Use a rubber grip tape cleaner (a stiff rubber block) to scrub the tape surface — this pulls dirt out of the grit. An old medium-bristle toothbrush with mild soap and minimal water also works. Allow to dry fully.

**Deck underside and trucks.** Wipe down with a dry cloth. Remove caked mud with a dry brush. Avoid soaking any wood components — water degrades the deck laminate.

### Adjusting Bolts

**Truck tightness (kingpin bolt).** The kingpin controls how responsive the trucks are to lean input.
- Tighter kingpin = stiffer trucks = more stable at speed but less turning response
- Looser kingpin = more responsive turning but more wobble at high speed

Adjust with a skate tool (3/8" socket on the kingpin nut). Changes of a quarter-turn at a time let you feel the difference before adjusting further. Beginners typically benefit from slightly tighter trucks; advanced skaters often prefer looser for trick responsiveness.

**Wheel nuts.** If a wheel is wobbling more than normal or not spinning freely, check the axle nut tightness. Tighten if loose; loosen slightly if the bearing is being compressed.

**Hardware bolts.** Check hardware before each major session. Loose truck bolts cause the truck to shift under the deck, which feels unstable and can cause falls.

### Replacing Parts

**Wheels.** Replace when wheels are worn down (smaller diameter, flat spots), cracked, or have chunks missing. Different setups for different skating: harder wheels (99A–101A) for smooth park/street, softer wheels (78A–87A) for rough pavement or cruising.

**Bearings.** Replace when cleaning no longer improves spin quality, when bearings are visibly rusty, or when the wheel rumbles during rolling.

**Grip tape.** Replace when the grit is worn smooth in key foot zones (front foot area, tail pocket) or when the tape is peeling from the deck edge.

**Deck.** Replace when the deck is cracked, has significant razor tail (the back tail ground to a thin point), or feels dead/soft underfoot (the wood has lost its stiffness from water or repeated impacts).
