I recently had engine work done and decided to swap in a new bell housing since the old one had a broken ear. I'm using the same clutch assembly as before. The problem is that the flywheel now rubs in the 4 o'clock and 6 o'clock positions. The six o'clock position is quite tight.
Shouldn't it rub all the way around? Are flywheels not perfectly round? Could the machine shop have dropped the block and slightly bent the crank; I can't see any visible wobble? Thoughts?? Edited by dgregg - 17 July 2019 at 7:26pm |

You said you swapped bell housings. Were they exactly the same? Flywheel on correctly? Pictures may help too as we may see something that you overlooked. |

Flywheels are perfectly round, but not so with the bell housing they turn in.
Later Jeeps, beginning with the CJ3A had a different bell housing to accommodate a larger flywheel and clutch. You didn't say what year Jeep yours is, but I see a 48 CJ2A listed at the bottom of the post. I have a late production 48 CJ2A which was built with some CJ3A components, haven't checked the bell housing yet, but it was built on a CJ3A frame, has the later style steering box with the horn wire coming out the bottom instead of the earlier brush assembly. An earlier bell housing would have the problem you describe if installed using the later flywheel. Is is possible you have the later flywheel? This can be determined by counting the teeth, or measuring the pressure plate. |

More info is needed:
What flywheel/clutch/bellhousing/starter combination did you start with? What combo are you having trouble with? Four o'clock and six o'clock inside the bellhousing, or on the flywheel? The late, 129 tooth flywheel won't work with the MB/CJ2-A bellhousing, and the MB/CJ2-A starter won't work with either the late bellhousing or the late flywheel. Also, the late starter won't work with the early bellhousing or the early flywheel. BW

I used to fool around with old VW beetles. When installing a later, bigger engine in an older beetle there were issues with clearance of the flywheel to transaxle bell housing. We would just grind them out where needed, and that was sometimes interesting because these are magnesium which when ground into dust can go up like gun powder if a good spark hits the dust.
I don't know if you could clearance one of the older bell housings to take a later flywheel, but even so you may still have an issue with the starter. At least they aren't made of magnesium. So, count the teeth on your flywheel, and that will tell us what you have. If it is the later 129 tooth, you will need to find a later bell housing.

Berrettajeep,
I have had this jeep for nearly 20 years so you may have seen me. I have the only red flat fender around Rootstown. Flywheel on correctly? It would seem the tapered bolts would guarentee alignment and I did alternate studs and gradually torque the studs down.

which flywheel? I'll go and count teeth after dinner. The starter is the same one that I used previously with this flywheel.

4 and 6 o'clock looking at the bell housing. I'm using the same clutch/flywheel as before the engine work. I'll count teeth after supper.

I count 124 teeth on the flywheel. It does rotate, but scapes the bottom of the bell housing. Maybe a little grinder work as old pappy suggests?

Could you take pics of original B-housing and the replacement? Also the starter. Does the pressure plate rub? Does sound like the wrong B-housing.

You could change the ring gear on the fly wheel and the Bendix gear on the starter to match. All the flywheels are the same diameter and the difference is in the ring gear. Jim

WeeWilly, I believe the starter and flywheel match as they are both original to the jeep.
Thanks for he suggestion.

Well, pictures were supposed to show up here.....
Anyway, both bell housings are identical. What I wanted to show was that after examining the grease pattern of the old bell housing, I can see that the flywheel cleared the 6 o'clock and 4 o'clock positions by no more than the thickness of a sheet of paper. ( There is a layer of grease coating the inside of the housing and it is very thin at the problem locations). I'm going to try to releave about a mm of metal at these locations with a grinder and hope for the best. Edited by dgregg - 18 July 2019 at 2:08pm |

dgreeg,
I ran into a similar problem 25+ years ago. In my case the flywheels tapered bolts hole had been drilled out per some service bulletin and replaced with non tapered bolts. This allowed for the flywheel to be (by mistake) installed backwards. The bell housing and everything else bolted up fine but the ring gear contacted the bell housing along its teeth inside. The fix was to turn around the flywheel and reinstall it the proper way.
Probably of no value to fixing your issues but perhaps it will save others a few minutes of wrenching at some point. Stev |

It is fixed now. I definitely had the right bellhousing. It had the half moon cut-out and a round cable entry, just like the old one. I found that it was also rubbing just above the starter opening. I used my angle grinder and was able to gain the clearance on the troublesome spots. It was a strange problem though.
If anyone has this problem again I would suggest painting the inside of the housing so that you can easily see where the paint was scraped off. Thanks to all who replied and offered their suggestions. Don |
