The fun continues. After tearing apart the Plane Power AL12-EI60 and ND -2130 I thought I would turn my attention to the B&C LX60 Alternator. Here's a picture -- hello gorgeous, what secrets lay within, I wonder?
The B&C appears to be a clone of the ND 101211-2950, 101211-2960 (DAN2017, DAN2029), and WAI 12651N, to name a few. However, the stator and SRE are clocked to 3'oclock, which puts the B+ terminal on the bottom side in a Lycoming installation.
1. The Drive End (DE) and Slip Ring End (SRE) brackets contain Koyo Brand bearings - 6202RMX and 6002RD, 35mm x 11mm x 15mm and 32mm x 11mm x 15mm respectively. No expansion compensation in the SRE.
2. The DE Bracket is of unknown manufacture, clone of the ND DE 101211-2950 bracket.
3. The SRE Bracket is also of unknown manufacture, clones of the ND SRE 101211-2950 bracket
Additional details - the O.D. of the DE and SRE case halves is 106.5mm.
4. The regulator is a clone of the ND 126000-1800, manufactured by MobileTron; model VR-H2005-60. B&C has reworked it's internals to bypass all functionality. It's just along for the ride
5. The rectifier is a clone of the ND 021580-3030, of unknown manufacture. It is comprised of a mixture of 8 diodes, 4 35A, 4 50A. The length of the B+ post is <31mm. There has been work done to remove the B+ connection to the regulator and make use of the external regulator.
6. The brush set is a clone of the ND 021620-2010, of unknown manufacture.
7. The stator is glued into the DE bracket after re-clocking. It is a clone of the ND 21100-2860, 50A. Unknown manufacturer.
8. The rotor is a clone of the ND 011200-5420. It has undergone quite a bit of balancing -- Almost every prawl (12) has some amount of material removed. The fans are pitched the same as the ND -2130 Toyota rotor, which is different than Honda and Plane Power.
9. B&C fabricated an additional bracket that bolts on to the SRE for a more stable mounting.
...and it's painted (not anodized) in gold...
My impressions -- The B&C is just another ND clone alternator with the weakest part of the system moved elsewhere (regulator). The castings are nicely done and finished and the machining is good, everything fits well, and operates smoothly. Like the Plane Power, the bearings are upgraded (NTN, Koyo) over the run-of-the-mill versions. Given the amount of balancing work done and the upgraded bearings, I can understand why B&C hasn't had the SRE bearing cavity issue, and other failures associated with vibration as the Pre-2020 variants of the Plane Power.
-- Post Script --
I'd like for the hive mind to weigh in and see if y'all might be able to figure out who manufactured the brush holder and rectifier.
The part number and date codes stamped on the brush holder and rectifier are very unique -- someone must know who does things this way.
e.g.
JT064-53
YY22B26
CT080-1
YY22B21
Cheers all!
