L134 starters

Anybody got a list of starters that fit an F134 motor?

 

I put this little chart together about 8 years ago.

 

Will the '68 Toyota Landcruiser starter also work with the flat-head 134 engine?

How about the flathead six that is in the wagons and pickups?

 

I don't think the Toyota starter works on the flathead but I have read it works on the F head. I tried the Toyota starter and I believe the sprocket or whatever you call the gear was too small in diameter.

 

You need a 129 tooth ring gear and the large frame starter bell housing which uses 1/2" starter mounting bolts. Doesn't have to be off an F134. Can be off a late M38 or CJ3A.

 

This may have shed some light on an issue plaguing progress on my 57 FC150.. My starter won't engage the flywheel..Now I'm thinking someone installed the wrong flywheel/ring gear combo..

Other than the obvious ring gear variances, are there differences in both the starters and bellhousings for the F head?

 

@jeepermc wrong flywheel may be possible but I would think you would hear a grinding noise. The starter gear may just not be engaging on the shaft in the starter and it may be spinning in place (rusted/needs oil/rebuilt). I tested a starter today off the engine and the little gear spun but did not move toward where the flywheel would be.

 

I had that thought as well.... I've had 3 different starters in the thing though and all tested good on the bench before install. The bendix appears to throw as it should when the starter is engaged on the bench. I think my only option left is to pull the trans and look. I have a "matched" bellhousing, flywheel, and starter that all came from the same f-head motor in the garage from a dead 3B that I may end up swapping in it this weekend. I'm still going to try to determine why it won't engage the flywheel though with the current set up. Thanks for the informative posts about flywheels.. Just what I needed for motivation!

 

If you look closely I give the ring gear cross section dimension so you can measure and determine which ring gear you actually have. The 97 tooth ring gear is the smallest and the 129 tooth the largest and it is possible you have a 97 tooth and the starter drive pinion is not meshing with the ring gear teeth. Since you have three bench checked starters I am inclined to think you have the small CJ2A flywheel which places the ring gear 3/8" further away from the starter pinion. There will not be a grinding to hear with this combination. Just the whine of the starter motor spinning it's drive in free space.

 

That's what I hear. Just the starter whirring away...Anything is possible with this as I aquired it in its current condition and I suspect the previous owner had the same problem since the engine swap was never completed and the starter was left hanging by it's wires when I drug it home. Unfortunately he is gone and I can't ask him... Will update after this weekend and hopefully I can say "success!"

 

isnt there a 9 tooth an 10 tooth starter gear? to correspond with the different flywheels

 

Yep. 10 tooth pinion is for use with the 97 tooth flywheel and the early small frame starter (long open face Bendix) and early bell housing. The overunning clutch drive (kick in style) in the small frame starter used with the 124 tooth flywheel is a 9 tooth and they are only used in the early bell housing. The later Bendix folo-thru drive (key start type) in the large frame starters was 9 tooth and used in the later bell housing with the 129 tooth flywheel.

 

great info thanks! Also are the 6 cyl flathead starters the same as the 4cyl? or are they completly different?

 

Not familiar with the wagons but they list the same 4137 starter as the CJ's with the 124 tooth flywheel ring gears until 1952. Then they use a different MCH series from 52 on with the 129 tooth flywheels. The CJ's use the 6207 and the sixes use the 6203 and 6210.

 

Success!! We swapped out the flywheel this weekend and had it running for the 1st time in 30+ years. It ran really well considering...
