"Mount the Alternator to the Engine block using the mounting bracket S01-620-4033-01. See drawing S01-620-0008 for mounting details. Drill a 3/8” hole in two of the alternator “feet”. Do not drill out the hole in the tensioning arm on the top side of the alternator as this is a 8mm tapped hole. Make sure the engine and alternator pulleys are aligned by using a steel rule or a straight edge across the face of the engine pulley and checking the position of the alternator pulley. The position of the alternator can be adjusted by adding washers between the rod ends and the alternator “feet” and the rod ends can also be adjusted vertically for angular alignment."
Hope this helps.
One additional note: check if your rodends for alternator mount are good and has clear identification. On the third or fourth SH which I assembled these rodends had no markings and one of them broke like glass in flight after only few hours.
In the pics it appears as though you used 2 short bolts instead of 1 long bolt, which precludes the use of a spacer between the rod ends.
I think two bolts were used in the very first batch of SH kits, back in 2003-2004. This gyro which is on my photos (blue frame) was the very first SH which flew from the Groens kit. I believe the drawing with one long bolt was issued later. Anyway I'm ready to agree with Stan that one long bolt+spacer is more proper setup. BTW this 2-short-bolts setups still serve on two first SHs I assembled - they still live somewhere in Siberia.
Do you know what alternator that was supplied with the kit ?
From my remarks (it was more than 10 years ago) it was AUTOLITE #14597, 45 Ampers
Is the fan important ?
No idea =) I just used that one which came in the kit. Interesting question indeed.
You guys are pretty awesome. I just bought an original SH that already had just over 300 hrs in the build. Alot of parts still left and hours to complete and these diagrams are nothing compared to the actual photographs.
Clearly, I will have to rely heavily on the experience and knowledge of actual builders of the SH.
Thank you all for your time and effort to make Rotary Wing forum what it is. Many questions to follow!
