Re: Wetserbeke alternator woes
Paul, that rear foot needs to be supported, as that front foot is going to be subjected to a huge amount of torque stress. Definitely contact Balmar and let them know that your alternator is being used on a 30B. They can put together a spacer package that will provide additional support for the alternator. The back foot on that alternator is designed to have a sliding rear bushing that takes up the space between the alternator foot and the engine mount. A spacer behind the mount, and a longer bolt that reaches through the rear foot of the alternator (with the rear bushing installed) should support the alternator better, as well as reducing alternator twist and the resulting wear to the bearings and the belt. You can see on your third photo that the alternator is already low in the back as a result of the lack of support. This will just about guarantee that the pulley/belt alignment will be compromised. Not a situation that can be put off.
