Wico X question

Were can you get your magnet recharged for a Wico X magneto (or maybe it's a magnetic rotor??? I'm not sure what it's called).

It's the magneto on our B John Deere.

Thanks if you can help.

Would Rudy Calin in northern MN do this? (Figure I can't reach him today.)
 
Meisch brothers garage by altura may be able to fix it I got a cap from them years ago Joe died a few years ago but his nephew Charlie took over and he says he learned to fix them from his uncle.
 
I am kind of with Kent on this one that is one mag I would look for other issues with. What is it doing and why do you think it needs a recharge?
 
It can be recharged by being put into a strong magnetic field. I just sold my magneto magnet charger that was made for the job. Note that magnets certainly DO lose magnetism over time when assembled in the magneto. Magnet will lose around 1% every 10 years. So a mag from 1950 will have lost 6-7% if it was never taken apart or subject to a lot of shock. If you take a mag apart and take the magnet out - it will go dead very fast unless you stick a "keeper" on it.
 
I have a very good magnet charger. I would bet someone hooked it up to a battery which demagnetizes them.
 
Wicco x mags do not require recharging under normal conditions. However if someone has connected electrical power to the mag it may have been magnetically discharged, this is according to Wico service and instructions & parts list form S421W.
Hope this is of help
 
jocco,

Our JD B just doesn't want to start quite right... nor run as well as it used to.

Tried different hotter/deeper spark plugs - which did help it start.

But he's had this tractor for about 38 years. Since he initially rebuilt it way back then, it has always started with 1 or 2 tries and always ran great. He's done other work on it over the years, and had something done to it last year (I think it was the head - but I'm tired and just can't remember right now... he is not available to ask).

Anyway, it just won't start right, nor run quite right. I think he recently cleaned the carburetor. Not sure how much he has messed with the magneto right now - but I'm pretty sure he has worked on that in the past too.

He's usually pretty mechanically savvy... but just can't put his finger on what the issue is this time.
 
If he's getting a nice blue spark from the mag, I would think the mag is OK. I do have a small magnet charger that we could try. Could it be a carburetor issue for the bad running? Maybe a road trip? Ron Mn
 
Ron,
I'll have to ask him... should have made sure I had a better understanding, before posting here.
Perhaps a road trip. :)
 
I really doubt your problem is the magnet. I buy and sell about 40-50 magnetos every year. I have yet to find one that had a magnet so weak it wouldn't work. Ninety percent of the time they just need a good cleaning and new points. They throw spark like crazy. I have had one or two magnetos that the magnet had come loose on the shaft and turned just a tad. This will cause them not to work correctly.

I would start with new points,condenser, and coil. Make sure it has good spark plug wires with copper wire core.
 
There is a good Mag man in the north metro. SLP or Fridley. He comes to junk show and exhibits. I'll try to get his number.
 
We had a magneto shop next to our Deere dealership in the 60s and 70s. Standard procedure when rebuilding a mag was to recharge the magnet. Anybody who sells an old mag as "rebuilt" and not recharging is not being thorough. It used to be a pretty routine practice. When the old guy died at the mag shop (Oneonta, NY) - I bought up his tools and inventory. Wisconsin engine parts and Fairbanks Morse and Wico mag parts. First time I tried to use the magnetizer - I did it with the magnet still in the mag. BIG mistake. It magnetized the impulse dogs and made them stick.

I don't have the stuff anymore. I just had my magnet recharged in my Wico XH mag by a mag shop in Maine.
 
Here is what my magnet charger looked like. Note that I recently needed an extra mag for my Oliver Cletrac. Somebody stole the old one. I got great service from Mainely Magneto. Great service and nice people to talk to.

If, he has had the head off, and say less than 150 hours on it, has not retorqued the head, this means, when it does start, and warm up, heat expands, and first thing to be effected is valve lash gap.
As it heats up, gaps tighten, and it will get to the point of not closing valves.
It'll pop out carb, or exhaust, or both.
Run a cold compression test, then get it started and run a hot test. I bet that you will find the psi readings to be off.
Check this before spending on a mag.
 
Weak magnets will affect starting and make a harder start but once running may not have an effect on performance that much.
 
Thanks.

I know the magnet being weak, did make a difference on our Farmall Regular. But the guy that recharged it, is no longer in good health.
 
Call up John Brillman and he will sell you a spare Magneto. I always keep a spare for my JD L and IH Cub
 
Points now days are not of the quality they were 20-30 years ago. He may try pulling 400-600 grit wet and dry sand paper thru the points and then a clean dollar bill thru them to remove any sand residue. Look at them close if they have white or black dis-colorization on them they are not making good contact and that's very important in a mag. Also does it have a good snap/click when turning engine over past LH impulse or no. 2 cyl.
