JBugs - 1971 VW Super Beetle - 009 Distributor Replacement:

Video Overview:

We've had one of our employee's cars sitting in our shop for awhile now and as it is the midst of the summer here in Phoenix, it 's not like he would have been driving it regularly. We had some free time in between other projects and videos and now that fall is just around the corner we figure we might as well get some work done on it. So after replacing the stock carburetor and getting the 009 distributor that was in the car properly timed, we pulled the 009 distributor out so we could install a SVDA (Single Vacuum, Dual Advance) distributor that comes with an electronic ignition. The SVDA distributor is far better suited for driving than the old 009 distributor. Plus, the electronic points set up works considerably better than the old points and condenser style ignition with less maintenance.

0:00 hi I'm Sam with jbugs.com 0:02 we're going to swap in a vacuum advance 0:04 distributor in place of a double 09 0:06 mechanical distributor 0:12 I prefer a vacuum advance distributor 0:14 especially on Street driven cars as they 0:17 just 0:18 operate much more smoothly with less 0:20 hesitation than a mechanical distributor 0:24 a mechanical distributor like we have 0:26 here are intended by Volkswagen 0:28 originally for industrial applications 0:30 like a sawmill or like a sump pump or 0:33 like a dredging pump where the engine's 0:35 either going at an idle if it's just 0:37 being warmed up or out to Full Throttle 0:39 at operating speed they weren't intended 0:42 to be used in places like a street 0:45 driven automobile or you want a smooth 0:47 Advance depending on the RPM and the 0:49 load that the engines under so as early 0:52 as the 1950s Volkswagen actually 0:54 switched to a vacuum advance distributor 0:57 for a smoother Driving Experience Distributor removal prep 1:00 so before we start 1:02 we're going to do a couple things before 1:03 we ever pull out a distributor we're 1:05 going to identify which one of these 1:06 wires goes to the number one cylinder 1:09 back here now as this is a double 09 I 1:13 know it's already set up I know that 1:15 this wire is number one so if I was to 1:17 follow this wire here 1:19 and look at 1:21 back here 1:23 I can see when I pull on this one 1:26 that wire goes there and goes there so 1:29 now that I've identified number one here 1:32 I'm going to turn the engine over 1:36 to this position and actually just 1:38 happens to be we're 180 out 1:41 so before I ever pull the distributor 1:43 out I'm going to put it at number one 1:44 good some good compressions 1:50 good compressions again 1:53 all right now 1:55 we know we're pointing at number one 1:58 and we know we're at top dead center 2:01 based on our notch 2:05 in the engine case right here 2:07 so number one 2:09 top dead center 2:11 additionally some Distributors not all 2:14 we'll actually have 2:16 a small scribe mark 2:19 on this top ring 2:21 to indicate the number one spark plug 2:25 so now the Distributors at top dead 2:27 center for number one 2:29 we can pull this guy out 2:31 foreign 2:35 like so 2:39 what we've got here is a mechanical 009 Distributor information 2:41 distributor this is actually a jf4 zero 2:44 two three one one seven eight zero zero 2:47 nine 2:48 zero zero nine is just what we've 2:50 abbreviated it to 2:51 Volkswagen did use other Distributors 2:53 that ended with double a nine but those 2:54 Distributors also had a vacuum advance 2:56 unit 2:58 so a double 09 is a centrifugal Advance 2:59 distributor and to visualize that if I 3:02 hold this shaft 3:04 at the bottom 3:06 the rotor and shaft can spin forward a 3:09 couple of degrees 3:11 this is the centrifugal Advance the 3:12 faster the shaft spins 3:15 due to the weights and springs inside 3:16 this will actually Advance or the 3:19 timing based on the centrifugal speed 3:22 this pertronics distributor 3:25 also has 3:27 that same 3:29 centrifugal advance 3:31 like the 009 3:33 however 3:35 it also has a stock style vacuum advance 3:38 and we'll demonstrate that right here 3:42 thank you 3:48 so you can see this plate here 3:50 [Applause] 3:56 actually moves 3:58 independently of 4:00 the distributor so we've got 4:02 a single vacuum 4:04 and we have two different advance so an 4:07 svda or a single vacuum dual Advanced 4:10 distributor additionally this 4:12 obviously we've got two wires coming out 4:14 as opposed to the one single wire here 4:16 this has an electronic ignition 4:19 whereas this is your old 4:21 points and condenser distributor so 4:25 tried and true pretty solid but a much 4:29 more common and much more 4:32 reliable system now with our new Distributor installation 4:35 distributor 4:38 we can remove the cap 4:42 and rotor 4:46 and if we look on this distributor here 4:49 we do not see an indicating mark telling 4:52 us where number one is so like I said 4:54 wherever this thing happens to land at 4:56 this point 4:57 nope 4:58 nope 5:00 nope 5:04 there we go all right 5:07 so as we see old number one used to be 5:10 here 5:12 now number one's back over here 5:16 and at this point I can 5:19 rotate this distributor 5:22 wherever I want 5:28 but for ease of use and adjustment 5:33 this is about the best place to put this 5:35 to indicate number one 5:38 I'm going to punch 5:42 this distributor 5:46 so now 5:49 we have an indicator 5:51 to tell us where number one is 5:53 now I'll note that we're still at top 5:54 dead center and number one 5:57 so from that point we can go ahead and 6:00 put on our distributor cap 6:02 after pulling that off 6:06 putting our dust shield back in place 6:11 reinstalling the rotor 6:16 and 6:17 get reinstall 6:18 our distributor cap 6:21 noting that lines up with that guy way 6:23 down there 6:25 and like I said all right 6:30 a couple things from here Spark plug wire installation 6:32 we need to get our 6:33 spark plugs on 6:35 and our firing order conveniently is 6:37 cast right into our alternator stand 6:39 this is actually an original German Zoom 6:41 photos one four three two 6:44 one 6:46 four 6:47 three two so we go one four three two 6:52 so we know this is one 6:54 and if we were to spin the engine we 6:56 know the distributor turns this way so 6:57 this is one four three two 7:02 make sure everything is fully Seated on 7:05 our wires there we go beautiful and our 7:08 last is number four Catching mistakes 7:11 I got it backwards did you see that oh 7:15 I was still thinking this was number one 7:20 so even though 7:22 I've done this before I still mess up if 7:25 you get the firing order wrong 7:28 if the engine happens to start it's 7:30 going to run poorly 7:32 it might backfire 7:34 it might not even run at all 7:37 so let's pay attention and do this one 7:40 more time 7:41 and this is number four 7:45 so I had our plugs 90 degrees out 7:51 now 7:52 the last wire left is our coil wire 7:57 now we've got two wires to hook up to 8:01 our coil before we hook up these two Checking coil resistance 8:03 wires 8:04 to our coil 8:06 we're going to check the resistance on 8:07 our coil to make sure our coil is 8:09 compatible with our electronic ignition 8:11 so we are looking for three ohms of 8:14 resistance 8:15 between our positive terminal and our 8:19 negative terminal now note I'm going to Important wiring notes 8:21 pull that up out of the way 8:24 our old green wire 8:27 was hooked up to the negative side of 8:29 the coil 8:31 note that we have a black wire 8:34 and the black wire going to the positive 8:36 side of the coil really important note 8:38 that we have a black wire 8:41 and another black wire 8:43 going to the positive side of the coil 8:48 these are hot wires 8:51 a lot of people see this black wire and 8:53 this black wire 8:54 and take this wire and plug it in here 8:57 to the positive side 9:00 what you've done 9:01 as soon as you hook up 9:03 the red wire to the opposite side which 9:06 wouldn't have any other wire there if 9:09 you hooked it up and try to start it 9:11 you've just fried your electronic 9:13 ignition 9:14 so green and brown are two common ground 9:18 colors from Volkswagen black and red are 9:22 both hot wires from Volkswagen 9:25 so just our two wires by themselves we 9:28 have 1.1 ohms of resistance for just 9:31 these two wires so we have to add that 9:34 to 9:35 what we get on our distributor by going 9:38 negative side 9:40 to positive side 9:44 we get 4.2 ohms 9:47 so we know minus that 1.1 1.2 ohms that 9:52 the wires have this is a 3 ohm coil 9:55 and it is compatible with our electronic 9:58 ignition now we've got 18 feet of wire Distributor wiring 10:02 that needs to go 10:04 six inches 10:07 now 10:09 we can go ahead and crimp on 10:11 the two terminal ends 10:14 that come with the distributor 10:17 however 10:18 if we look at our coil 10:21 we can see our positive side coil 10:24 has three posts 10:26 and it already has three wires we've got 10:31 our positive circuit running to our idle 10:34 solenoid and the choke 10:36 we've got power from our ignition switch 10:38 and fuse box 10:40 more specifically the ignition switch 10:41 this circuit is not fused going to 10:44 provide power to the coil and then on 10:47 the back side here 10:49 we've got power to our reverse lights 10:51 so we've got three terminals that are 10:53 already taken up 10:55 we need to plug in another positive wire 10:57 you can pick up some piggyback 10:59 connectors like this here this will 11:01 allow you to plug in 11:03 two wires 11:05 onto one terminal 11:07 our idle solenoid from that terminal 11:10 along with our power terminal here so 11:12 we've got those two wires 11:14 I'm going to plug on our piggyback 11:18 over here 11:21 and I'm going to plug in 11:23 our power wire 11:25 on one terminal 11:27 and our solenoid on the other 11:31 all right now that'll give me 11:33 this terminal in this terminal four our 11:36 positive wire and our negative wire 11:45 we'll strip off 11:47 just about a quarter inch 11:51 we'll crimp them with this 11:57 and 11:58 double check that we have a secure 12:00 connection 12:01 this is the positive side with all the 12:03 black wires positive side of the coil 12:05 has the black wires 12:07 looks weird but we're going to plug in 12:09 the red wire 12:12 the black wire is going to go to our 12:14 negative side 12:15 if you happen to have a tachometer in 12:17 your car it will also be plugged into 12:19 the negative side 12:20 most Volkswagens 12:22 don't necessarily have attack so there's 12:24 probably not going to be anything on 12:26 this negative site moreover if your car 12:29 was running before 12:31 the green wire from your distributor 12:33 would go to the negative side so if 12:35 nothing else where the green wire was is 12:38 where the black wire goes the red wire 12:40 goes to the other terminal 12:42 now the only thing we have left to do is 12:44 to hook up our vacuum from here 12:46 before we hook up our vacuum we're going 12:49 to set our Max Advance on this 12:51 distributor without the vacuum hooked up 12:53 so we're going to keep 12:55 our carburetor plug 12:58 and we're going to time this thing Max 13:00 timing we're going to set it 32 degrees 13:02 just like we did with the double 09 13:04 and then we're going to hook up our 13:06 vacuum line to our carburetor and we're 13:08 going to take this thing for a spin 13:10 negative clip we're going to clip onto a 13:13 good ground 13:14 we're going to take a positive 13:16 right off of our generator 13:18 which won't actually provide Power until 13:22 the car is running and charging and our 13:25 inductive sender we're going to clamp 13:27 this around 13:28 the number one spark plug wire well this 13:30 is number four so this is number one 13:31 back over here 13:33 this is just going to sit around the 13:35 wire 13:36 like so but again we're going to do that 13:40 on the number one spark plug wire 13:43 back over here so that hooks up our 13:45 timing light 13:47 at which point we can go ahead and get 13:49 this thing fired over 13:51 and get our initial Advance set 13:53 I want the distributor clamp tight 13:55 enough 13:56 or I can spin it easily enough 13:59 but not loose enough where it just spins 14:00 freely as this car hasn't been started 14:03 today first thing I'm going to do is hit 14:06 the accelerator pedal to open up the 14:07 choke 14:10 one pump 14:14 we know it are generally white oil 14:16 lighter on just good safety keeping to 14:19 make certain that we know everything's 14:20 working as far as our indicators 14:27 not well timed but it was running here's 14:30 the fun part is when you're doing this 14:31 single-handedly 14:32 [Music] 14:33 it's not starting and running turn it a 14:36 couple degrees 14:40 [Music] 14:43 that's not working 14:45 turn it back the other way 14:49 that's our 14:50 little turn it about there see what she 14:52 does there 14:57 [Music] 15:04 we're getting nothing there 15:07 it was running better the other way 15:09 in lieu of everything else it's always 15:11 good to have an assistant 15:13 to crank the engine over Finding and correcting a fuel leak 15:16 go ahead 15:18 oh hold on hold on hold on 15:21 I just noticed 15:23 we've got a little leaking fuel here 15:27 so 15:29 before we continue much further 15:33 I want to see what's going on here 15:37 so we're going to 15:40 [Music] 15:42 nip the chip 15:46 hope we've got a new 15:47 fresh segment of rubber 15:52 good and tight 15:54 now just because it hasn't started that 15:57 well and when it did start 15:59 it wasn't running that smoothly I'm 16:01 gonna go back and double check the 16:03 firing order make certain I didn't screw 16:06 up because guess what 16:07 I've done it a couple times so we're 16:10 going to give another try with our handy 16:11 cameraman cranking the key while I turn 16:14 the distributor to get our initial 16:16 timing set 16:19 [Music] 16:50 foreign 17:01 foreign 18:25 foreign 18:51 now that we've got our timing set 18:53 and we've got our carburetor readjusted 18:56 to a about an 800 RPM idle now that it's 18:59 warmed up we should be able to just turn 19:00 the key 19:02 and it starts right up 19:06 perfect 19:09 now we're going to tighten our 19:10 distributor clamp fully 19:13 and we're gonna hook up a back of mine Installing vacuum line 19:17 we're gonna Purl 19:19 our vacuum from the side right there 19:25 and this will go down 19:27 to right here 19:28 and 19:30 just because we want to have some extra 19:32 for 19:34 future 19:35 shortening if need be 19:38 we'll give it a fresh cut 19:41 and 19:43 like so 19:45 our vacuum is hooked up 19:47 disconnect our timing light 19:50 all right Pre-test drive inspection 19:59 good starting 20:29 pulled off to it 20:38 let's take her for a spin Test drive 20:46 [Music] 21:09 gusta mucho 21:16 [Music] Final inspection 21:41 foreign 21:47 well with that 21:50 we can call this card done 21:53 one more thing but I'll probably do that 21:55 in a short I don't like that shifter 21:57 we'll probably swap that out to 21:58 something else but 22:00 anyway otherwise 22:02 with the new carburetor and our new 22:04 electronic distributor with vacuum 22:06 advance 22:08 this car is ready to go 22:10 and his owner can go enjoy it once the 22:13 summer cools off a little bit out here 22:14 in Phoenix 22:15 thanks guys take care 22:19 [Music] 22:27 well I'm Sam Mebane and I'm here to say 22:29 I love working on Volkswagens every day 22:33 that's a wrap
