Installation for E-225. First point: The shaft of the new alternator is 1/2 inch. The shaft of the old 50amp generator is 11/16 inch. So you will need new the nut, gear, sleeve, bushing, retainer and hub for the 1/2 alternator shaft, at a potential cost of nearly $1000. So now this is a $2200 unit but it is worth it. Its such an improvement over the old generator and voltage regulator. These 1/2 parts can be found serviceable on old 35/50amp generators which had 1/2 shafts, maybe for free. Second point: The recommended wiring diagram, which you should use of course, ends up by-passing the original ammeter on early model Bonanzas. So you have to add a supplemental ammeter, another $200 to $500 expense. So now this alternator is a $2500+ unit. It is still worth it. Just be ready with 1/2 parts and a new ammeter
Ordered the kit so I would have everything I needed and it is missing the volt regulator. Very disappointing.

I purchased this alternator as a replacement to my Jasco . Both Plane & Power as well as Jasco are now produced by Hartzell Engine Technology. The plane and power is actually based on a Japanese automotive alternator. I was told the diodes, brushes, etc are enhanced. Overall I am happy with my purchase. The Installation manual could use some improvement. It is not as clera s one would think, there notes over the two page sheets, and you have to decipher what they are trying to convey. The product support at Hartzell is excellent. I am very pleased by Hartzell product support and appreciate their help. In general comparing the price with other alternatives available, I would recommend this item.

Great product. Lacking or erroneous instructions. Says you can use original light if equipped. Also had to call tech support because unit was overcharging and popping output breaker. They said a direct wire from alternator output to sense on regulator is needed instead of the the jumper from the field terminal it comes with. Other than that, the alternator and regulator are quality items.

Bought the kit for the Generator to Alternator Conversion, and it was straight forward, and fairly easy to do. Its great not having to worry about electrical power anymore, especially since we have a Uavonix AV 30 for the Artifical Horizon now., I can turn on the high beams and the alternator will take the load Thanks. only down side its expensive, but what is not in an airplane
Night and day change for my j5 Cub. Full voltage at idle with landing taxi lights, nav lights, radio, sooooo happy. Battery staying fully charged. Replaced my Delco Remy generator and so easy. One evening of effort.
Put this on A C172 with an O-300. It is a great upgrade!
Alternator is great but shaft does NOT match up with original and the gear kit was mandatory. This would be nice to know up front to save multiple trips and delays…

easy installation, instructions were a little vague, but it’s so simple it’s easy to figure out, customer support has me wondering though called a couple of times only got answering machine, left a message, phone call not returned. Product is excellent would have been five stars if they returned the call. Be nice if they gave a sample 337 as so many others do

Please note, Aircraft Spruce Australia'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 Australia 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.
Per Hartzell, "Field current varies with the amount of load requested by the bus. However, we do recommend a 7.5 amp circuit breaker be installed in the field system at installation."
Yes, this would be an acceptable core.
This is 144".
That is not included. It is only needed if you dont have the gear assembly or if your gear assembly is unusable.
The gear is not included. It is 5.6 inches from the flange face to the end and it is 4.2 inch in diameter.
This does not come with the gear, you would need to reuse your gear. We will be updating the photo soon.
The installation instructions do not mention a specific clocking when installing.
You would keep any of the parts you would need for the installation of the new assembly. They will just not take a core back if it is in pieces.
The manufacturer recommends to only use their voltage regulator with their alternators.
Package size approx 6.5" X 7.75" X 11.375 at 9 lbs.
