Ok fellas I am diggin into a 3 prong coil...pics of my progress so far on the 2 prong below. I dug away alot of VERY VERY hard epoxy with a dremel cutting lines in the epoxy and basically using a rug knife and small screw driver to dig and pry the stuff loose.

Any one have any ideas on where to find the positive terminal in this sea of impossibly hard epoxy?:00000060:

Now where do I dig on the 3 prong one?

Ironically, I haven't had the personal pleasure of having a Suzuki coil crap out on me yet, my experience was with other brands.

As for your early 80's 2-legger coil (1 magnet on the flywheel), this person over on GW did the aftermarket transistor retrofit on their p/n 80-1990 ~Toro has since superceded the 80-1990 with the 17-1529~ and has this to say;

As for your 3-legger coil (2 magnets on the flywheel), used since 1985 I beleive, the transistor module should be under the pronounced "bump" on the coil itself, just center of where the high tension lead enters. Another option someone did was removing the coil itself off the iron core and replacing it with another ..off a B&S or Tecumseh if I remember. Anything to avoid Toro's $200+ extortionist replacement cost on this bugger.


All this is assuming you've already tried "baking" it back into service, albeit usually temporary service ?

Toro actually mounted these transistors externally with a separate wire lead to the coil, on their snowblowers that used this same 47P engine. Guess they thought the heat and vibration was much greater on them due to the enclosed engine on these units. Probably a good idea to do the same for the aftermarket transistor on your mower, place it out in the airflow, while still protected.

Viking could we use the snowblower coil and flywheel on the mowers?

I'll check into the retrofitting the iron ware from another coil these coils look very close to Briggs.

Sure can. Many of the 47P parts off the CCR3000 (and CCR2000 I believe) will interchange.

http://www.partstree.com/parts/?lc=...R+3000+Snowthrower,+1997+(SN+7900001-7999999)

A few will not - carb, muffler, starter ..mostly from the engine being tilted on it's side in the snowthrower configuration. Actually, it looks like the recoil starter is the same functionally, if not visually.

Sorry to veer off topic but does the CCR3000/2000 have a cast iron flywheel? Would this mean you could run a 47P on a non-mower machine, i.e., without a blade?

 

[viking427]

Never owned a CCR snothrower, but yes, I believe it does have an iron flywheel. Snowblower applications use a cast iron flywheel to maintain the required spinning mass & inertia for smooth running/idling, where the mower engines use an aluminum flywheel with iron magnets imbedded in their perimeter - and the steel blade provides the needed mass and inertia.

Yes, you can use the 47P (or any engine for that matter) for other applications. Some folks build small generators out of mower engines and use a heavy iron pulley or sheave to provide the mass/inertia.

Hmmm, wonder if adding an iron flywheel would help the 47P plow through some 5 inch tall Bahia.

That's cool, thanks for the info. I really like these engines and have some "ideas" in my head.

I am going to try the coil and flywheel swap (froma snow blower) on one of my commercial mowers-as another alternative to epoxy mining. Once I can get the epoxy clear without destroying the inside of the coil it will be nice and we'll have multiple solutions for dead suzuki coils.

I have emailed the people who said they did this on Garden Web but I have yet to get a response fromt hose that claim they've been able to do this...:dunno:

..just wanted to add a few more links to discussions on the 47P coil failing problem and transistor modules (both aftermarket "Nova II", "Mega-Fire", etc. and the factory Toro "Xstar"). Toro used the module on their CCR2000 model 38180, 38181 and Im sure other model Snothrowers as well. Good to know the 47P coil heat-fail issue isnt specific to just the mowers
