IH 240 Starter Bendix

Hey folks I'm a regular on the Ford 8N forum, but have a bendix question on a starter for an IH 240 for a buddy of mine.

The gear on the starter has a few broken and the rest worn teeth. Also pretty sure the bendix doesn't move the gear far enough to contact the fly wheel.

Anyhow I have the bendix pulled out and want to replace it as a unit. Cant find any p/n on it. Seems like there are a few different types. Following are some picts.

Found a bunch on fleabay but dont want to waste time ordering the wrong one.

They seem to sell one on this site but dont offer a picture.

Any help is greatly appreciated.

Sorry only one gear that i know of that is in the pict. Is the ring gear something that i am not seeing?

As in the ford 8N's, I thought the bendix drive assy consists of whats in the pict.

Thanks
 
the ring gear is on the flywheel. check the teeth on the flywheel to see if they are still good. you would have to split the tractor to replace the ring gear. or, the gear can be removed and flipped over to use the other side of the gear. i didnt see the pic either on this site store, but you can call them for more info. i have ordered quite a few parts from this site and have always been happy.something to check also, is how far the bendix is traveling to engage the flywheel. there are some shim washers on the armature that set the distance. lay a straight edge across the starter mounting hole on the tractor and measure in to the flywheel teeth . then compare that to how far the bendix on the starter travels. you may need to swap the shim washers on the armature.
 

Thanks for the tip. And yes I have ordered a bunch off this site and have always been more than happy. Unfortunately with no pict I get a bit uneasy.

I notice that there was a black tie wrap, around the bendix see pict 1 and 2. You think it was put there in place of shims?
 
yup, looks like they were trying to stop the bendix from fully retracting. the shims are washers that go on either end of the armature. to get more travel from the bendix, move one of the washers from the end of the armature on the bendix side to the opposite end by the brushes.
 
If you have an "auto-electric" shop near you, they can probably get you one, if they don't have one in stock already. Mine had one... said there are usually several starters that use the same parts. One more thing to check with the owner... has he changed the tractor over to 12V? If he has, that may have a lot to do with why it went bad. This is what happened with mine. My guy told me what happens with a 6v starter on 12 V is the starter spins too fast before engaging, and although it generally works, it can wear on the drive gear and the ring gear teeth. Mine starts 100% better now because along with rebuilding the starter with a new drive, he changed the field windings to 12V. It never started so good as it does now.
 

There should be a number on the starter. Either on a tag that is riveted on, or stamped into the main body. Pretty sure the starter will be a Delco. If you can find that number, order a bendix to match. Your local Case-IH dealer most likely will have it in stock.
 
Dealing with the ring gear is the last thing anyone wants to do. Generally unless it is REALLY bad you can get by with just a new bendix.

Your new bendix may be a "clutch" style which is much better and provides more positive engagement. It will not look the same but if it fits the shaft and has the right size gear, it will work.
 
thanks folks for all the help. It definitely is converted to 12 volt which is probably the reason for the chipped teeth on the gear.

going to try to talk him into converting his starter to 12 V first otherwise the same issues are going to reoccur

Starter drives will all eventually fail. That's just how it is. There are bunches and bunches of older tractors, converted to 12 volts, with the original 6 volt starter, and the starter drive failure rate on those tractors is no different than if the original 6 volt battery was still in use. Just put a new drive on the old starter and go. It'll probably be good for another 10 to 20 years.
 
you are defenitly correct. 12 volts on that bendix
makes it slam extremely hard meshing into the ring
gear. someone good with a die grinder can reshape
those teeth again. i have one w6 tractor out of a
bunch of 6 volt units i have, that was converted to 12
volt. i just hate engaging the starter as it just
slams with a bang. its just not my forte'
 
The washers on the armature are not designed to be swapped to the other end. You will have two washers with a smaller ID. They go one on each end of the armature to limit the end play. The other two washers, one thin and one thick, have a larger ID and slide over the armature shaft to limit the forward movement of the drive assembly. If you replace the drive you have with the newer style you do not use these two larger washers.

Here is a picture of the two different style drives.

Notice the step on the right end of the armature on the top picture. The smaller washer goes against the step to limit end play. The larger two go between the first one and the end of the drive to limit the amount the spring stretches when the drive spins out against the stop collar.
