Looking at the following pictures of a just rebuilt 1971 Bus transmission, what do you see that's wrong?

I'll play. The face of the housing where the starter goes is painted. The starter needs that to be clean metal for grounding purposes.

Then why is it that Eric at Transworks says out of 900 transmissions he’s done he’s only had like two complaints? He always paints the starter pad. _________________ Lead Mechanic: San Diego Air and Space Museum

They misspelled your name on the toe tag but I’m with Spike. Was all that paint necessary? Seems like no paint at all would be better or is that powdercoat? _________________ Keep on Busin'

I dunno, I always hit the starter pad and starter face with a wire brush or sand paper to get to fresh unoxidized contact...
though I also often add a Gnd cable from the starter bolt to the chassis.
I really hate starter issues
I'm starting to solder on a pigtail to the Key/start spade as I've had a few of them loosen up on me and pop off. _________________

Eric thinks the starter gets it ground well enough through the mounting stud. He says that an unpainted starter face that’s magnesium will soon corrode anyhow. _________________ Lead Mechanic: San Diego Air and Space Museum

Well the most obvious is that the entire transaxle is painted black. Believe it came from the factory unpainted in just raw metal. That is how I am restoring my ‘67. Want the stock look. |

I am with Eric on that as long as the engine is clean where the D head bolt nut goes on, and the ground strap has a good connection to the nut holding it on too. _________________ “Most people don’t know what they’re doing, and a lot of them are really good at it.” - George Carlin |

The bolt hole or stud hole and threads are wallowed? Because I can't see daylight I'll guess that a stud should be in that hole?

They forgot to paint the cv flanges. Or is it the 1970s vinyl floor. _________________ 1972 Bus 1700 cc Single Carb. But not a progressive.

because that was from the 2 fools that didn't clean the bell-to-engine mount and the starter pad _________________

Well I just spent 45 minutes trying to prove that the pad needs to be clean and unpainted. I measured resistance through the starter both ways with uncertain results.
For me, I makes sence to have the best bond possible but here I am with hat in hand unable to prove it. _________________ Lead Mechanic: San Diego Air and Space Museum

Just makes sense to me that since the starter needs lots of current, you should have as much conductive surface area on the ground side as possible. He should mask that area before painting it. He may know trannies, but he doesn't know electricity. Bet I can guess what Telford would say..... _________________ If you haven't bled on them, you haven't worked on them.

Starter motors can pull up to 300 amps during operation, so it's not like a standard multimeter can mimic that kind of current draw. I think the electrons need a safe and easy way in, and a clean base flange certainly helps that.

I'm guessing the nice clean stud serves as a decent ground for the first 5 years. |

Starter System Quiz
1 - Does a starter need a lot of current? Yes.
2 - Does resistance vary inversely with contact area? Yes.
3 - Do VW starters need the best connections possible to work right, every time? Yes.
4 - Is paint normally an insulator? Yes.
5 - Did the factory paint the starter pad? No.
6 - Did the factory know what they were doing? Yes (generally - see notes below).
So - quiz: should you (a) paint your starter pad, or (b) scrape it and the starter flange as clean as possible? (five points for the correct answer)
Ans: ______
Notes: Q6 is answered 'generally', because if they got it perfect the first time, there would be no need for changes from one model year to the next. _________________ '71 panel, now with FI
