I would like to answer Bob N.’s points and questions from July 30, 2010, in parts. This is about the John Deere Rectifier/Regulator AM101406
I would like to use the JD101406 Rectifier/Regulator, as in Z09,in place of the Jabiru supplied unit. I understand that this might be a more robust option.
John Deere has consistently offered a bit more
heat-sink performance on their rectifier/regulators
so your substitution is probably a good thing. Do
you know anyone else who has made this substitution
and is flying it?
No.
I had thought that I had read that Bob had recommended this. With more research, I found 21 posts about AM101406 going back to 2001. I find that Bob has said such things as “consider” and “a possible solution”, etc.
However the following items influenced my decision to plan on using the JD R/R unit:
From Matronics:
Here in Australia a lot of people have ditched the std Kabota
tractor Regulator supplied with the Jab engine as they only tend to last 6 months .( although some have lasted years). if you have any elec problem's, the first step is to chuck the old reg and buy another one and also carry a spare on fly aways. Or use a Powermate or some other product that meets your needs
Consider one of the John Deere tractor regulators
like the AM101406. These are heavy duty critters with
hefty heat sinks.
I certainly did not want to think about having to carry a spare R/R when going cross country.
Also from Matronics: | Quote: | | http://home.hiwaay.net/~langford/corvair/dynamo.html |
This person reports 800 no problem hours using the JD R/R however it is with a JD alternator. Following is a quote from the website:
OK, so then I dropped by the John Deere dealer and asked the guy at the counter how many of those he sold…….I asked about the regulators and he said "the only call I have for those is from these guys that are putting them on airplanes".
Also Bob’s Z09 shows the JD R/R (but again coupled to a JD alternator in a Corvair conversion).
With additional research, I decided that I liked the idea of using the JD unit especially if it is designed for use at 35 amps (the Jab alternator is only 20 Amps). Also if the Jab supplied Kabota R/R is fragile as indicated, I would like to use something more robust.
My research also revealed that JD may not continue to be supplying the same R/R as discussed here. See my posting of June 24 2010. It also appears that different manufacturers might build their R/R in the same OEM heat sink. The Kabota looks like it is built in the same heat sink as the JD. And some are built in heat sinks with almost no cooling fin area.
