I don't really have that much practical experience with living with a
Convert, although I have wrenched on a couple. I understand that the
charging system can be a problem. On paper, I know that the 'Vert has a
20 amp alternator. Not huge, but a popular upgrade for the 15 amp unit I
used have on my old "T". I wouldn't think that an extra couple of amps
for a pump would be a problem. I think the problem with the Convert
charging system is that the engine revs can be pretty low at normal
cruising speeds. Is there a fix for this? I'm thinking maybe a re-wire of
the stator, improved rectifier and/or regulator, swap it out with a more
modern alternator (newer Guzzi). Or I guess for the custom, put the
Kubota alternator on and belt it to an appropriate speed, like was
mentioned before.
Sorry about all this Convert crap. Just remember, Mike started it <:-).
Hey, what is the rear-end gearing for the Convert? Isn't it way high?
Maybe that is what John's buddy needs for his Merc looper.

i would assume it don't need to flow much - just enough to keep it
circulating through the cooler..i think the real problem lies in the
amp
draw of the pump. with very little amperage to spare, that pump
could drain
the system of juice quick..
which catalog page was that gear pump? - i couldn't find it..

Subject: Re: Convert QuestionsI don't know the specs on the stock pump. I guess the purpose ofthe pumpis only to circulate fluid through the system for cooling, right?Isuppose we could do some testing. I looked in the McMaster-Carrcatalogtoday. They have a gear type pump with Delrin gears and a 12VDCmotor forabout $47.00 I'm not sure how a fuel pump would work, but thisgear pumpwould probably work good on ATF. Rated for 13 fl. oz./min 20 PSIor 63fl. oz./min @10PSI on 200 CPS fluids. Max temp 200 degF. 1.6 ampdraw.huge
For guys that maybe aren't familiar with McMaster-Carr, they are aindustrial supply house. Probably every manufacturing plant in theUS hasat least one of their big yellow catalogs in the maintenance orLoopframe
engineering office. They have a great web site too
http://www.mcmaster.com. I buy lots of MC stuff from them too.tool box locks, vibration mounts, various hardware, fateners ofalltypes. Order online and they ship it fast!much..
