I need some help with my ‘67 beetle.
Description: I was at a stop light. When it turned green, I attempted to take off when the beetle made loud bang and the car lunged forward. The sound was not like a backfire but more like something giving way. The engine remained on. I could feel the clutch petal still working, and it seemed to go into gear. However, the engine would not engage the tranny in any gear—including reverse. When I press the gas, I only rev the engine. I cleared the intersection and coasted to a friend’s house.
Current situation: I assumed it was a clutch issue since I could not access any gear. Once the new clutch came in, I took the engine down and removed the clutch. Here it is:
to my eyes, it looks good—almost exactly like the new clutch in the box!
For reference, here are pics of other parts:
Everything in the drive train seems solid. If the clutch is not the problem, what could it be? _________________ Proud owner of a ‘67 sedan daily driver! |

Pull your rear drums and see if the splines that engage the axles have stripped out. With a stock open rear differential, it only takes one to strip out for the car to be unable to move under its own power.

Yes, this is also unfortunately too common, from poor quality drums and/or axle nuts not properly torqued and secured with large cotter pin. _________________ 1970 VW (owned since 1972) and 1971 VW Convertible (owned since 1976), second owner of each.

VERY interesting! I was already planning on changing the drums, shoes, and cylinders. It’s a good thing I already have the parts! Hopefully, that will be the issue. _________________ Proud owner of a ‘67 sedan daily driver!

Do not purchase drums from rock auto as they more than likely will be out of round. That was my experience with them...just sayin. _________________ Volkswagen: We tune what we drive.

Stripped axle splines has my vote. Shake your clutch plate, if it sounds like a maracas with the springs rattling, you need a new one _________________ Daily driver: '69 Baja owned 44 yrs - Plan B: '81 Rabbit Diesel LS Deluxe - Plan C: '72 Ghia

I wanted to provide a follow-up to my original post here. The problem was stripped axle splines in my rear drums. Ah well! At least she now has a new clutch!
While she was garaged and off the road, I replaced brakes and drums all the way around. The brake pads did not need it, but I went ahead and replaced them to go with the new drums. It was then that I discovered that the front driver side brakes are a different width than the rest. These are narrow and will not fit the wider brakes found on the other 3 wheels. After replacing the drums, the narrow brakes barely fit inside! To add to my confusion/frustration, even adjusting the cylinder, the brakes grab, making it hard to turn the wheel manually.
Unfortunately, I now have absolutely NO brakes in the pedal! I tried to bleed them, but I broke off the bleeder screw on one of the front cylinders. Each bleeder screw required a different size to bleed the brakes and I got fed up and used pliers to bleed them. (Good thing I already purchased new cylinders!) Like most things I’ve discovered, various parts were used to keep her on the road through the years. I should not be so surprised at discovering just how patched together this car’s systems are! (Did I mention it appears to have been cobbled together?) This is certainly a labor of love!
Follow up questions to my “new” brake issues:
-How would I rule out master cylinder concerns? Would I need to go ahead and replace the cylinders at the brakes then try? I was able to successfully bleed the rear brakes, so SOMETHING works right!
-The front driver’s side brakes are narrow. It will not accommodate the newer, thicker brakes. Will I need to replace the rear face plate to get the new brakes to fit? _________________ Proud owner of a ‘67 sedan daily driver! |
