Weird it must have some meaning.
Other wise why stamp the big D on it, LOL.
I can see it now:
Boss - "My nephew needs a job."
Foreman - "We don't have any open positions"
Boss - "Make a job!"
Foreman - "OK"
Later that day:
Nephew - "What does the D stand for?"
Foreman - "We lost the B punch so we are using the D to mark which side of the pulley goes toward the rear of the car. Get back to work...." _________________ Selling the SB:

my buddies pully just has two V's cut out on the back "engine" side of the pully and no other marks... any idea on which is TDC/BTDC ? We can't figure it out and we need to set his timing so he can get my super he bought from me rollin' the streets again with his engine and this is the last thing needed doing.... He has a 009 dist which I know how to set at full adv. 3500+rpm 28*-32*BTDC but ????? which mark to go by is unknown and I looked the pully over hard and can't find any other marking of any kind _________________ Donate and help me get another aircooled dub to share with you guys www.paypal.me/WhosCare |

How close are those two V's together? Just a couple of millimeters? If so they are probably 7.5 and 10BTDC. |

ok, well this was very helpful. I am having some valve adjustment issues and had some confusio of where TDC was. So now I know. the only question is if the rotor should point exactly to the mark on the dizzy AND the notch be lined up with the center of the case. And if they dont, what to do about it. _________________ If it was easy anyone could do it!

For valve adjustment, it doesn't have to be exactly 100% TDC, it can be a few degrees off on either side and still adjust OK. |

Make sure you have your spark plug wires in the firing order and the notch on the distributor as number 1. |

Is there a dimple on there too, the rounded thingy on the outer section? It should, if it's a pulley made in the early 70s that is. Just compare the dimple to the 7.5 before and 5 after, it's very likely one or the other of those two choices. |

did you ever figure out if the single notch was 5 or 7.5? I have a 74 also and a single notch on the pulley.
I would guess the nothc stands for 5 ATDC and I should set that in the center of the split ccase when timing? |

I'm not sure what the single mark means either... I have a '74 Standard Beetle that has only one mark as well. If no one else answers this, I should be getting a degree pulley soon, & I can match up where the mark is to the degree pulley. Don't hold your breath though, I'm not sure when my Buddy's bringing the Dizzy & Pulley to me. He's over 100 miles away! With gas prices the way they are, I don't see him coming untill he's ready to make the journey... |

Thanks guys for the information about distribuitor advance and regulation of valves, are very utility, for me, hellos |

66 Shorty, my pulley had the 1 mark as well. I pulled it off and matched it to the paper template that is posted here earlier. It ended up being 5 ATDC. |

I hate to keep beating this dead horse but I've put the seeds of doubt into my own head.
I totally understand the difference between the "dimple" and the "v" on the pulley. My only question is, where should the "V" be when looking at it with a strobe timing light. Does anyone have any pics of the "v" in the proper positions?
I mean, if the dimple is TDC, and I'm supposed to be 7.5 BTDC, then the dimple AND the "V" should be to the right of the split in the case, correct? Also, when checking your advance, how far to the left of the split should the "V" go?
Glenn's initial pic shows the dimple on the split which to me, means 0 degrees. And the wheels on the bus go round and round, round and round... _________________ "Unpimp ze auto"

The v would be to the right of the dimple. When you time it statically (engine off), the light would come on when #1 cylinder is about to fire, so the v notch is lined up with the case centerline.
If you use a strobe timing light here's what you do depending on what kind of timing light you have. I'm assuming your distributor requires 7.5 deg BTDC advance.
- With a standard light, at idle, the v notch would line up with the case centerline. A better way to set timing is at max advance. Paint a white line 30 deg to the right of the dimple, then get the rpms up to 3500. Adjust the distributor so the white line lines up with the case centerline. This diagram can help you with the 30 deg mark.
- If you have an advance timing light (where you can dial in the advance right on the light), paint the white line at the dimple (0 deg), and set the light to 30 deg. Then spin the engine to 3500 and line up the white line with the case centerline.
edit: I'm assuming you time your distributor to 30 BTDC at 3500 rpm, typically with vacuum hoses disconnected and plugged, but confirm your setup first. _________________ Mike

Dang....the "v" should be seen on the case split??? That's my problem all along! I thought the "v" would be to the right of the case split. No friggin' wonder.
I have the variable advance timing light so I can also check the max advance timing. _________________ "Unpimp ze auto"
