1970 Beetle Drivebelt check, adjustment and replacement

*Drivebelt Check/Inspection* Do this before wasting money for a good belt...
First, check your drivebelt for these conditions: streaked sidewall, glazing (white crap on the belt), fraying (the inner part of the belt is corroding perpendicularly to the belt itself, inside to the outside), oil soaked (no comment...), cracks (no comment...), cracks (similar to fraying, only worse and deeper), tensile break (basically, a section of about an eighth- to a quarter-inch break where nothing else is that bad), separation (what a part of the belt splits from the main part of the belt anywhere).

*Adjustment* Use a flat screwdriver to hold the pulleys from the slot at the top of the belt system.
Use the washer rings that are on the front of the pulleys on the bolt to tighten or loosen the belt system. More washers will loosen the grip and distance of the belt, where reciprocally less washers tighten the pulleys together and tighten the belt. Easy, right?

*Replacement* Do this if your drivebelt has the damage listed above, or any other damage not listed that you think may impair the safe operation of you vehicle.
Do the steps above to take the nut off of the bolt of the belt system on top (in case you forgot or are lazy, use a flat screwdriver placed at the top of the belt system in the slot to stop the belt system from turning. Once you get the nut off, pull the washers (if not in use) and the first half of the pully off; place in a safe place. Remove the old belt, and put the new one on in its place, placing the top of the belt on top of the pulley on top. Replace the removed pulley part then the washers, then place the nut back on and tighten by hand, then tighten by ratchet or adjustable spanner. Make sure that the belt is tight enough. If not, remove the washers and the first have of the pulley and place one of the washers onto the bolt between the pulley halves to tighten, or remove one to loosen it; replace any removed washers onto the bolt so that the nut holds them in place (so you dont lose them). Done.

Good luck. And as before, I am not responsible for any damage done to your vehicle for improperly replacing the drivebelt or other parts that need replacing.
