Oh, it isn't the alternator, it's the regulator. Now I understand.
I've seen a few different regulators rewired into these and they seem to work ok with some rewiring.
Other than the splicing, what is wrong with your regulator. Is the unit charging ok?

The regulator is charging OK but I want to change it . The way my regulator looks I can expect problems so I want to have a spare.

So if you have any informations , please share.

Thanks.

Found this :Regulator Rectifier Tecumseh 610749, AM102596, 610749 (http://www.ebay.com/...480bf4a&vxp=mtr)

Bought it , hope in 10-12 days I'll receive it .

 

Meanwhile study , study , study for tachometer connection. Had to buy another counter frequency meter . The old one just fell down from the engine while measuring .Dead !!! :wallbanging:

 

Keep in touch .

Aw, that's bad. Sorry to hear you lost your meter.
Good luck on the regulator.

Read a lot and done a lot of tests .

From the ignition coil couldn't have a good signal .Found out that the tachometers instaled in trucks and cars take signal from alternator , point "W" .So I took signal from one of AC alternator wire.
T01.jpg

The tachometer has a push button for settings that sets from 1.0 to 10.0 in 0.1 steps .Don't ask me what this do .With setting 5.9 it works .I have to take the MF outside to make extensive tests .My wife is not happy with me reving the engine indoors. :cowboy_shooter:
Made the "calibration" with my old laser tachometer .Here is another problem . The gases from exhaust are interfering with the laser beam and give me sometime wrong readings . So again I have to take it outside .
T02.jpg

A little test :


The hourmeter is working.
I think I'm on the good way .

One more thing . Call me stupid :hitting_self_roller: but after watching the video with tachometer I had a revelation : the ampermeter shows a number with "-" when it draws current and without "-" when the battery is charging .
I see that at high revs the voltmeter shows 14.5V . Is this normal ?
And I put about 2 litres of gas in the tank and the floater is working too .

Keep in touch .

If you rev up to 2500 or so, does the voltmeter go higher. I think 14.5 would be OK as long as it doesn't go much higher.

Thanks for the update.

After all the work you've done, I agree, change out the voltage regulator, while

you're at it.

Looks like volts are running a bit high, for the rpm's  you where at.

 

As for this.....

.My wife is not happy with me reving the engine indoors. :cowboy_shooter:

 

Don't you guys have shopping malls over there? :D  :D

@IamSherwood

We have a few malls but my better half is not much of a shopping addict . I had to pay for my "tractor madness" with a 12 days 5 stars all inclusive stay at seaside abroad . :boo_hoo:  It was much , much cheaper to send her shopping.

 

 

I installed the implement drive clutch pedal . I didn't had the original spring so I had to make an adaptation .

Ped1.jpg Ped2.jpg

I don't like how the pedal pulley sits . It seems that is a litle inclined .Please take a look and tell me if this is OK.

Ped3.jpg

 

Brought inside the tiller I started 2 years ago for my homemade tractor . It was to heavy to lift it by hand at my old tractor.Now I have power lift !

 

T1.jpg T2.jpg

T3.jpg T4.jpg

 

and some pics. from the beggining of construction.

t01.jpg t02.jpg

 

Have to make the connection from the implement pulley and the tiller pulley .And obtain at the tiller a 200-250 revs/min .

 

Keep in touch

I think if you move the crank pulley out a bit it will line up better.

That tiller looks great! It will be fun to watch your progress on it! I don't have any experience with an MF 12, but do you think the engine will have enough power for that size of tiller?

I think the pedal piece may be bent slightly. It is also possible the crank pulley is on to far, but check the drive belt for alignment, that will tell you for sure.

Didn't had time to post what I've done in weekend .

Found some pulleys in store , don't like it very much becouse are made from aluminium .But I think will work .
Made a kind a gearing plan . Hope my knowledge from school and what I found on the internet are good .
Gearing.jpg

My reasoning is that if I have 1.000RPM at engine I will have aprox 250RPM at tiller . Please , if someone is better than me at this post an opinion.

I pull out the implement pulleys ensemble and reverse it . The bigger pulley is outside . Pull out the smaller pulley and put a even smaller one - to gear down .
Fu1.jpg Fu2.jpg Fu3.jpg
Fu4.jpg Fu5.jpg Fu6.jpg
The rest you can see in the drawing.
Made on the lathe a spindle for the second ensemble .
Axel1.jpg Axel2.jpg
Have to make the bearings housing from the blanks.
Hope it will work .

And I made a test with a 165kg weight (360lbs):


Keep in touch .

I came up with the same final RPM result, using this calculator.

Well actually 251.79
