|
|
Now that the weather isn't so nasty, my 65 project is finally moving along again.The pans are in and the chassis painted and now I need to think about reinstalling the transaxle. But before I do I am wondering if I shouldn't do more than just change the fluid. The car was a daily driver before I started the restoration. It ran great and had no problems shifting, so I don't think anything is wrong. That said, I'd feel like a fool if I put it back together only to have to take it out again because I neglected to take care of something a 50 year old transaxle would naturally need.
I do think putting in a new clutch would be smart, but because my car was converted to 12 volt I don't know what to buy.
thanks in advance |

Sounds like the engine is out so it should be easy to see what flywheel and clutch setup you have. Post a photo.
These transaxles are pretty robust and if they were never ran low on oil they will last a good long time. There's really no "user-maintenance" things to do except change the oil and the rubber axle boots (make sure that if you have split replacement boots on there, that they are installed with the seam off to the side and not straight up)

While the tranny is out, check your motor mounts and the rubber boot the clutch and accelerator tubes go thru as they exit the chassis.

All of the above and...
...check to see if the shift detent plugs are still in the trans and in good shape. They were made of plastic and totally fall out causing an oil leak when they get old like these have...
If they are still there, test their integrity by probing gently with a sharp pick to see if they crumble or flake apart. If so, you would want to replace them now when the trans is out...

There is also a fourth smaller one in the lower part of the gear carrier housing, have a look at it too for same reasons....

I'll look over those plugs and bushings this weekend. I did think about a new nose cone, but not about just that bushing or the ones for the torsion bars. The accelerator cable sheath seems ok.
Here is a pic of the clutch. Whoever modified it to 12 volt used a clutch made in Brazil. I want a new one from Germany if possible, though I don't know what to order.

That brazilian Sachs is pretty decent clutch.
What havent seen mentioned is the input shaft seal... Another must on 50 year old transmission. _________________ ✠Miklo✠

Whilst you have the gearbox out, why not also change the input shaft seal? I always do, and helps prevent a contaminated clutch in future. Plus change the starter motor bush, which is a piece of cake to do at this stage, and costs little or nothing to do. |

Remove the starter and clean all the mating surfaces where it contacts the starter housing. Clean all the starter electrical connections and the wire contacts. _________________ Roads Scholar &

Also grease up those surfaces to keep oxygen and thusly corrosion for as long as possible. Dielectric grease or bulb grease are best. _________________ In Stereo, Where Available! |

2nd gear synchro? That's the first one to fail, since it gets the most use. But if you don't remember grinding the gears while it was running, you might pass on it. Only hard part to replacing it is the Belleville washer you have to compress to get the snap ring on or off the shaft. |

before you re-install tranny, use a wire to clear open the breather hole near the top. it is often clogged with grime. a clogged breather can cause leaks at seams/seals. if you want, clean up the case and paint it, the magnesium case is pretty reactive to chemicals an salt, a coat of paint will help reduce corrosion. a nice thin coat of matt black would look good and be protective. _________________ Help Prevent VW Engine Fires, see this link.....Engine safety wire information

Being an old thread, I'm afraid no one is looking at it. But if so can anyone help me find the location of the breather hole near the top mentioned? Thank you I have a 71 Super Beetle. |

Starting on the right side of the image above.
First section is the nose cone.
Second is the gear carrier, I think!
The breather hole is on top of the gear carrier section. That is if my memory serves me correctly.
See the correct answer below. _________________ I have learned over the years.

Thank you SNRF61 for the picture of the breather hole location.
While cleaning the transmission out of the car today, I found another mystery hole on the driver's side transmission side cover at the top. There was not one on the other side. The hole was almost completely clogged. and I started to clear it with a pick but wondered if I might be damaging some type of screen inside. Any ideas on what this hole is and if I should try to clear it somehow?
shows the cover plate and a close up of the hole is
Thank you[/img] |

@laststarfighter
That hole is an unused part of the casting and not drilled through. If it were there would be a big trail of oil leaking from it.
