OK I an stumped and need a suggestion. I have replaced Bendix drives before with no problem.
The Bendix gear broke, and I am replacing it. When assembling the Bendix drive to the starter motor shaft, the end (long shaft bolt hole in the end piece) will NOT align with the indentation in the starter drive shaft by 1/2 bolt hole diameter. I am trying to get this fixed for the 4th of July parade. I HATE hitting and forcing a part. Anyone have this difficulty in the past and have a suggestion/ Thanks
I don't know how to fix your problem but have you considered blocking off the starter holes and using the crank?
well, you could just install the starter sans bendix rather than blocking off the holes. That's if you don't get this puzzle solved before the parade. Hopefully it won't come to that, though.
It seems like a straightforward problem. I would compare the old and new drives to see if anything looks different or 'off' about the new drive. Also inspect the starter shaft for any burrs or bends that may cause interference. If there is some slight interference. Try applying a little lubricant to the shaft before sliding the drive in place and see if that helps.
Now that you have the drive off remove the starter and fix the problem on the work bench. It should be easier to find the problem and then remove the drive and replace all in the car. Scott
Jeff has the right idea. Unless you have the blocking plates on hand, it's pretty unlikely you'd get them by Thursday (7/4). If it comes to that (hopefully it won't) just install the starter and bendix cover without the bendix, crank her up with the crank, and you're good to go.
Which way is the hole off? Is it not going on far enough or is it off side to side? If not going on far enough, shaft may be bent a small amount. This will not let the bendix go into the bearing. If not off side to side, spring may be twisted. Are you using 12 Volts by chance? Dan
I don't quite know what part you are talking about. The bolt goes through the drive head which is a separate piece from the gear. Unless it was broken, you could use the same drive head which was on your old bendix. There is a key which goes in the shaft and when the drive head is aligned with the key, the bolt should fit right in. If it doesn't fit, your supplier has made a mistake. Maybe someone in your area has a drive head which you could use.
David : I think your starter drive head # 5019 don't go in the head sleeve # 5021-1/2 .Just turn the head sleeve a little so that they fit.
Thank you all for the advice. Unfortunately with a broken back and shoulder, hand cranking right now is not an option. Since the 12 volt bend ix gear broke, the shaft may have bent
the unit needs to slide towards the ring gear a 1/16 of an inch for the bolt head to line up with eh end hole in the starter shaft.
I am wrong, if key is in the correct the hole can not be off side to side. The key could also stop the head from going on far enough. They (keys) like to fall out. Dan
You are either hung up on a bur or the key cocked as you were sliding on the end of the Bendix. I would pull it off and start over. If you still have the problem, then I would take a small plastic mallet and see if it will tap in place.
Dan and Ted thanks. I am going to dress down the key slightly to see if that is the most probable cause.
Solution to the problem for future reference
The tailpiece, the shaft bearing that fits into the engine by the ring gear, was not fully screwed on and fully seated. Therefore, the assembly would not move in the 1/16 inch required to assemble the retaining bolts.
