Hello,
I'm working on the engine of my 914 1.8 from 12/73 (L-jetronic). The butterfly of the trottle body is very sticky and I want to replace it. I searched the internet and was not able to find such VW part... Any ideas were to source this part in Europe...? Many thanks. Butterfly partno.: 022.133.141A   Thanks for the replies and shared info... I already took the TB apart and cleaned is. The bearings and seals seem not bad. See below pic what I believe causes the sticking, a ridge has formed over the years. The butterfly sticks on this ridge (IMHO).  So some kind of honing of the bore and a new butterfly...? |

Butterfly partno.: 022.133.141A Have you tried to squirt penetrating oil into the bushings of the shaft for the butterfly? If you do need the take it apart the butterfly screws are flattened in the ends to prevent them backing out. You need to grind them down to not ruin the shaft when they are removed. I doubt the butterfly is the problm unless it is damaged. |
