Last night I was within 15 - 20 minutes of wrapping up my alternator replacement job when I overtightened and snapped one of the two hose clamps that connect the Y-pipe to the plenum.

Local hardware and auto parts stores only have the standard 1/2" wide stamped hose clamps. One of the auto parts guys called my broken clamp a "heavy duty" clamp because the slots in the clamp are not the typical stamped slots.

For any of you that have broken or replaced these clamps - where did you get replacements?

Thanks,
Trevor

 

how about dealer?

are you talking about the Y pipe to the TB... those are not heavy duty... on the contrary they are only 3/8th thick... take one off there should be a size stamped on it... like 80 to 100. and thats in mm.... go to Mcmaster-carr.com and order one... but if thats the case just go to the dealer...

 

Woops, didn't even think of the dealer - good thought.

Yeah, it's the Y-pipe to TB. The 3/8" width is part of the problem - most of the hardware store clamps in that diameter are 1/2" - 5/8" and I wasn't sure those would fit. If I recall correctly, the rubber tube / coupling between the Y and the TB has some slots to keep the clamps in place.

 

Success! How about this for service - my local Porsche dealership didn't have the part. I told them that I knew it was a 70 - 90 mm clamp with a 9mm band. Apparently, the parts guy called around some local shops and found one for me! Hopefully I'll get everything back together tonight.

 

told u...lol

I get them form Mcmaster-carr.... they have the same German ones for the all the clamps... turbos, etc etc...

 

I was seconds away from placing an order with McMaster-Carr before I found out about this solution. MC is great with shipping - I can order as late as 2p or so and get stuff next day. I love that place ...

 

This just happened to me this afternoon, same job - alternator replacement. I was 30 minutes or less from having the job finished. I didn't have a spare car to go to the dealer, so I'll go tomorrow and hope they have one.

 

Yup..McMaster Carr rules...buy those clamps by the bag, and everything is always delivered the next day....

 

This was my first time taking stuff off the top of the motor. Porsche loves clamps and clips!
