Overview

BC410-H Alternator

The BC410-H is the original high-performance spline-driven alternator that mounts on a standard vacuum pump accessory pad. It may be used either as a primary or a stand-by alternator for a nominal output of 20 to 30 amps, depending on engine RPM. Designed for many hours durable service, the BC410-H features a dynamically balanced rotor, heavy-duty sealed ball-bearings, 2 internal cooling fans, and a special “shear section” designed into the drive coupling.

The BC410-H is externally-regulated, and may be used in either 14 and 28 volt homebuilt aircraft using our LR3C-14 (14V), LS-1A (28V), or SB1B (14V or 28V) Controllers.

Measures 4.6” (diameter) and 6.0” (length), and weighs 5.75lbs. The BC410-H will clear a stock tachometer cable on Lycoming engines, as well as B&C Oil Filter Adapters.

NOTE:
L-40, BC460-H, BC410-H, and BC462-H alternators require external regulators - use: P/N 07-06742 (LR3C) for 14V Primary, P/N 07-06786 (LS-1A) for 28V Primary, P/N 07-03461 (SB1B-14) for 14V Standby, and P/N 07-03462 (SB1B-28) for 28V Standby.

B&C BC410-H ALTERNATOR SD 40AMP HOMEBUILT

July 31, 2021

Perfect replacement for an older SD20 that was installed in the aircraft. The alternator actually has higher output at a lower RPM than the one it replaced.

Well built Alternator that actually fits on the vacuum pump drive mount on Lycoming IO390. I bought the slightly larger model BC462-H but it did not fit, it interfered with standard oil filter although it also said it would fit on that same accessory pad. Turns out it only fits if the optional 90 degree filter mount is used. Now trying to get refund on the BC462-H.

Q&A

Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician. Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Q: Will this alternator fit on the rear of a Rotax 912 engine?

Both the SD-20 and the SD20-S will fit Rotax 912 and 914 engines on an available vacuum pump accessory pad. It should be confirmed in advance, however, that the engine in question is equipped with the necssary vacuum pump drive gear (some may not). Eligible pads on Rotax engines turn at a ratio of .54 to 1 of engine RPM.

Q: Is the SD-20 alternator still available? Should it be replaced by the BC410-H?

Per B&C the SD-20S looks to be the BC425-H now.

Q: Whats the difference between a BC410-H and a BC410-I?

The BC410-H is for experimental aircraft only. The BC410-1 is for certified aircraft.
