Default Parts source for rebuild

I just replaced my PP alt on my 10. I’d like to rebuild the old one to have as a backup. Does anyone have a source and parts number for a rebuild kit?

Thanks!

How do I "register" with Vans?

My PP went out at about 300 hours. Replaced and installed a blast tube.

I talked to Hartzell about my experience at Oshkosh this summer and they confirmed that they will not rebuild a PP alternator. Replace at full price is only option unless still under warranty.

They did say that they have talked with Van's many times and have asked Van's to add a blast tube installation in their plans. To their knowledge Van's has not done this and said any installation without a blast tube will likely fail as the heat build up in the tight cowling installation will cause a failure.

150 hours since the blast tube installation on my new PP alternator and so far so good. We will see.

I have 450 hours on my B&C alternator mounted on the vacuum pump pad. I installed it with a blast tube per the B&C documentation.

Can you post some pics of your blast tube set ups?

.
My (Hartzell/PP) documentation for the PP EI60 alternator states the blast tube is NOT necessary.

Just reporting what he told me. Not sure if he meant the issue was specific to Van's cowling installations.

Also checked my PP documentation for both the old and the new alternator. Neither mentions a blast tube but neither one says it's unnecessary. Also checked the current PP documentation on line at Hartzell. It's the same as what I received.

The installation doc's for the AL12-EI60/C (or B), part #99-9900B & C revision F calls for a 1" blast tube, see page 2.

Document available here:

https://planepower.aero/aircraft-alt...-instructions/

Also, there is a specific blast tube adapter part available for the 70A variant (AL12-70), part # 10-3051.
