Racinbob 11,702 #1 Posted March 8 Switch gears for a bit this morning. Some of you saw the blurb on the starter for my B-80 K-181. It was squawing something terrible and was definitely a bushing issue. I replaced it with an aftermarket. Had a little alignment issue that I fixed and, not mentioned, it pushed the shroud out a bit when it was engaged. Removing the dust shield fixed that. The old starter only needs a quick cleaning and rebuild. So.....on to my next simple project. What could go wrong here? Simple teardown. A good cleaning and I'll have a spare on the shelf. I picked up a rebuild lit on the flea and it kinda looks good. @Lane Ranger mentioned that he had bushing size issues with his. Sure enough. The back bushing looks good. The front bushing is a no-go. Wrong diameter and flanged. I'm thinking the correct bearing shouldn't be too hard to find. But I've heard me say things like that before....................... Anyways, these things are quite simple and as long as the windings are OK should be piece of cake to get back to new condition. I'll let you know about finding that bushing. 4 4 Share this post Link to post Share on other sites
ri702bill 8,940 #2 Posted March 8 The most difficult part is the compressing of the springs and brushes at the same time at assembly. I made up four u shaped sheet metal parts for that... Share this post Link to post Share on other sites

Racinbob 11,702 #4 Posted March 12 @Lane Ranger Lane, you mentioned that you had a guy that you were going to take your starter to. Does he have the correct bushings for the gear end? I haven't knocked this one out yet but it looks like it may be an oddball. Share this post Link to post Share on other sites

Bob I will ask when I take my old B-80 starter to him. missing one tooth on Bendix. (Supposed to be 16) and pretty well worn! Thanks Bob for the washer idea placing under the PTO side of the starter to align my new replacement starter. And taking the motor tin off to see how the alignment fits is also a good idea when placing a new starter on a motor! 3 Share this post Link to post Share on other sites

It didn't like taper shims and grinding didn't seem like the answer either. Make sure you manually inspect the alignment once you put the washer in place. In my case it was excellent. Apparently the bracket didn't get welded exactly right. Our two aftermarket starters were from different manufacturers so . Again, if your starter guy or anybody here knows where to get the correct bushing for the gear end let me know (post #1) I want to save the old Bosch.

Lagersolut 720 #7 Posted March 30 I have 3 old starters here keep wanting to rebuild - one the gear shattered - is there a source for a replacement gear ? Share this post Link to post Share on other sites

I see NOS gears on eBay. Count the number of teeth yours had so you get the correct one. There are at least 2 different numbers of teeth Share this post Link to post Share on other sites
