W109 300 SEL Heater Lever Replacement

Sunday's all day project: installing new heater levers to replace all four of the existing broken ones. I followed this great article http://w108.org/articles/heaterlever1.pdf and used all factory parts from MB Classic. While not for the faint of heart, the work was manageable and I only encountered a few hiccups along the way. The biggest issue was replacing the seals on the heater valves, one of which was leaking. The article mentions marking the valves to make sure they're installed in the same position before removal. Sadly, they didn't mention that the valve stem position is the crucial item, not the retaining ring. Took about a half hour to figure out the correct position during refitting. However, the levers all work great now and everything is functioning as it should. I left the aftermarket radio out in preparation for the original Becker to be reinstalled. MB sure knows how to make things complex!

Nice job!

It's been some years since I've done a set of heater levers and valves, but I do recall that it wasn't a pleasant job. What's nice is when you're finished and how nicely they work compared to the way they had been previously....

Thanks for the encouragement! It is definitely a satisfying conclusion to have the levers and all associated items working.

I'm about to initiate having that done...I emphasize, 'having it done' because I just don't have the touch to get it done on my own....So my independent will tackle it. Your link will be on his screen . Thanks for sharing your journey...

Good luck with the replacement. That link and article were invaluable to do the work. I ordered all of the parts mentioned using their newer numbers. I should have also ordered clips for the cable ends. I don't know if the part numbers didn't cross over correctly or if they simply weren't mentioned in the article. Who do you use as your mechanic in NYC?

Nobody in NYC.... I have a guy up in Massachusettes that handles my work.

If you know the part #'s for the clip ends mentioned, please pm me....
