Difference in Staters

Postby bud29376 » Tue Feb 26, 2019 4:11 pm

What would be the difference in a starter for a1950 - 1951 and a starter for a cub made during 1952 - 1954?

Also how about the International cub starters any difference?

All the same until you get to the 12 volt
There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

The starter is the same

The lever for the starter switch is different in 1950 at SN 128799 which also charges the pull rod

short http://www.tmtractor.com/new/el/347fp.htm later above

Hi,
There were 2 model numbers of Delco 6 volt starters used.
1109603 was used first, up to Cub serial number 128798, and originally had a sheet metal switch, with the long arm, for the rod.
1109611 was used beginning with Cub serial number 128799, and had a cast metal switch, and the short arm for the rod.
This info is from an older Cub parts manual, TC-37D.
The 2 starters look the same, like was said before.

The 12 volt starter is different, it looks different, and has no switch on top , and uses no pull rod.
12 volts began at Cub serial number 224401.

Below are pages from the Cub parts manual, showing the starters, if you need them.

If you were thinking of putting on a 12 volt starter, Jim Becker has said on here that a 12 volt starter probably won't fit on a Cub made for the 6 volt starter.
IH changed the block to make room for the 12 volt starter. They are bigger diameter, and there isn't enought room on an original 6 volt Cub for a 12 volt starter.

Isn’t the only difference the water outlet has an indent in it?

No, there is also a difference in the curvature in the block at the base of the oil filter housing to accommodate the larger starter on the 12v cubs.

No, the R8 block has a different casting shape/location for the oil filter housing for the 12v starter to fit. BTDT.

Along with the switch change, the field coils of the starter were different. I never tried swapping them, but assume they will. You probably would want to swap them as pairs.

As already stated, the 12-volt starters have a larger diameter. The block and elbow were both changed for clearance. The hardware that holds the lid on the oil filter also changed.
