Yikes....
Better get on the stick asap.
Thanks, Benzmac.
I see that you sell the 14mm wrenches.

Do I also absolutely need the "holding wrench for valve spring retainer (615 589 00 03 00)" ? Looks like it will make the job easier if working solo.

Also, will the two 14mm valve adjusting wrenches and the above holding wrench work on all the 61X engines ?
Want to adjust both the 617.912 and 617.951 engines...
