I have the same setup as Bill. I did go back and forth with installing a 90 degree B&C adapter with the Plane Power FS1-14. Ultimately it ended up being too much of a pain, and the oil filter in its standard configuration is not in that bad of a location for me to deal with that pain and extra gasket in the path.

I do have a 90 adapter and spacer if you are looking for one. I was too lazy to return it and I have not got around to putting it in the classifieds.

Which alternator Bill? If you are using an oil filter adapter My understanding is that spacers are mandatory for clearance.

I just realized that I posted the photos of my old alternator, which was the Plane Power. That has now been replaced with the Band C after the PP failed. The B&C is essentially the same form factor. I am not using an oil filter adapter. It's a close fit, but works. Yes, I have an inline fuse in series with the output lead of the Alternator. I'm sorry, but can't find any photos of the new B and C installation using the 40A alternator. Ill take some photos this weekend and post with some actual measurements if I get a chance.

Here's a photo of my SD-20, which has been relabeled the 40amp from B&C.

This is before I installed the oil filter adapter and hung the engine. I have to modify a ratcheting wrench to get the one bolt installed. It was a pain before the engine was hung and even more of a PITA to get it off after I was flying.

I don't have a copy of a photo of after the oil filter adapter online to share at the moment.

Bob,

So you're saying it's a pain to get the 90 degree adapter installed, but would you also say that it's "worth the pain" of installation? Did you have to modify or grind down anything to the get clearance between the adapter and the alternator housing, either for install or other reasons?

Bill brings up a good point in his write up: If you have the modify the alternator to install with the 90 deg adapter, it makes replacement of the alternator more of a PTIA..

No, I'm saying the bolt that holds the alternator that is located between the alternator and the oil filter is a pain to put in with the engine off the plane. It's even worse when the engine is mounted.

I had to modify a ratcheting wrench to about 3" in length, then it was only able to move a couple teeth at a time. There just isn't enough room to maneuver. When the engine is mounted, you have to do it in the blind.

Once the oil filter adapter spacers are installed, that problem goes away.

I didn't install the oil filter adapter until a couple years of flying. I wish I put it on day one. It's a godsend!

I had no modifications other than the spacers that B&C provided. Now if you install anything else than this model alternator, you need to talk with B&C.
