A word of caution on the condensers. Evidently there are two different ones with the same number! Both have the base numbers Bosch 1-237-330-037. One is a short condenser about 18mm x 23mm diameter. This is the one that you need for these mowers. The other is a longer one, about 1/2" longer and is a smidgen wider. I purchased some brand new and found that even though they had the same numbers, only the short ones would work. They have extra numbers on the end for the long and short ones and are apparently made for different kinds of engines. I also bought two Bosch GB550 (the modern equivalent for Bosch 1-237-330-037) and one turned out to be the long type and the other the short one. The long condensers with that number do not seem to work. So a word of caution, don't just go by the number. Make sure you order the short one 18mm x 23mm diameter.
