Massey Ferguson To-35

James Madison Ag dep. · Feb 24, 2014

i am looking to convert from a 12 volt generator to a 12 volt alternator on a 1955 TO-35 Massey Ferguson. how would i go about doing this?

If you check the archives there are a good number of diagrams for using the Delco 10SI like what Chev used in say a 1980 Chev pick up. Simple 3 wire hook up and your done.

If you still want the tach to work get the alternator for a late MF 175 or 180, some AC tractors had the tach drive too. You will need a seperate voltage regulator though with either alt.

will the original belt work? or do i need to order one?

First step is to procure an alternator. Most people go with a Delco with an internal regulator, fits mid 70's-80's GM products. You will also need the wire harness plug, available at the auto supply.

You will need to fabricate a lower mount. The reason you need the alternator first is to get the pulley alignment right. This is essential, take careful measurements, use straight edge, whatever it takes to get a good, solid, straight fit.

The wiring is simple, search "Delco alternator wiring" under images and you will get the diagram you need. You can reuse the "GEN" wire from the generator, just move it to the "BAT" terminal of the alternator, disconnect the other end from the regulator, then disconnect the "BAT" wire from the regulator, and splice the two together.

You can reuse the "field" wire from the generator, it will connect to the "1" term of the alternator, but remove the other end from the regulator and series wire a 15 ohm resistor or a 12v instrument lamp to the ign side of the ignition switch.

The #2 terminal will simply jump to the
"BAT" terminal.

Original belt may or may not work, depending on your mounting setup, and the pulley diameters. Get everything set up first, then measure how long a belt you need.

Just for your info. The early 70s delco alternators where external VR systems. It was 74 or 75 when they switched that is why I say an alternator for a 1980 Chev pick up that way you do not confuse the auto parts guy LOL

i have a MF TO-35 that i want to put a 12v alt on mine also but i notice that the existing belt is way too fat or wide for the pulley. can the pulley be changed out ?

most of the time the pulley off the generator will fit the alternator may have to space it on way or the other as to accommodate the fan

Yes, you can put the generator pulley on the
alternator. Just be sure the spacer behind the
pulley is right before tightening the nut or you
can break the housing, bend the pulley.
