Guest ratchethack Posted July 15, 2005 Share Posted July 15, 2005 the boss on the pawl arm in the machine WAS THE EXACT SAME SIZE as the replacement arm I bought to be swapped in56215[/snapback] Dan, what size is that? Link to comment Share on other sites More sharing options...
Baldini Posted July 15, 2005 Share Posted July 15, 2005 Dan, just cos it's a replacement part doesn't mean it's the correct replacement part! like Ratchethacks asks....what size is that? Guzzi have a service bulletin out about these breakages acknowledging incorrect sized boss - says replace spring & pawl arm. Measure it first tho!

KB 56229[/snapback] Sorry for the late response, out of town for a few days. Yes, measured with a digital caliper, both bosses were the "correct" 15mm. I put the newer arm in anyway, hoping for better luck. Dan Link to comment Share on other sites More sharing options...
dbdicker Posted July 18, 2005 Author Share Posted July 18, 2005 OH my. You guys are GOOD. Apparently, I got a replacement arm with the same dimensions as the wrong stock arm. I think I ordered the part mentioned in one post for the replacement arm number: 04 23 52 01. There is another part number referenced in a different post: 04 23 51 01. Perhaps the number I used referenced the old, stock, wrong arm? I did not think to measure the boss of the new arm and my mechanic mentioned in passing that they were the same size. I NEVER thought that they were the same (wrong) size! But they are. Well, back to the drawing board. I'll order a new correct arm, wait for this spring to break and do it again. Or maybe, I'll just do it again...........why wait for it to break. Bugger. Link to comment Share on other sites More sharing options...
Baldini Posted July 18, 2005 Share Posted July 18, 2005 ....both bosses were the "correct" 15mm... ....they were the same size......the same (wrong) size! ..... Confused??? You bet!!! Dan, my understanding is that the correct spec pawl arms carry same, original part no as wrong spec ones: 04 23 51 01 KB Link to comment Share on other sites More sharing options...
dbdicker Posted July 19, 2005 Author Share Posted July 19, 2005 I got the 'wrong' part no. from a poster here in the forum, it's been forwarded to the FAQ page and put into this now wrong post on part numbers. Letter to Al: change the part number in the FAQ! I got it wrong!) I'll order the correct part number today. Feel like a dope. Link to comment Share on other sites More sharing options...
dlaing Posted July 19, 2005 Share Posted July 19, 2005 So, which is correct, 04 23 51 01 or 04 23 52 01 ? EDIT sorry, I re-read the posts. So, 04 23 51 01 is the correct one Link to comment Share on other sites More sharing options...

dbdicker Posted July 19, 2005 Author Share Posted July 19, 2005 OK, new update. Called all around the US parts guys; MPH, Harper's, Motointernational. Apparently, the part number IS NOT sufficient to insure you get the arm with the 15mm boss. There are still old arms floating around with the wrong 16mm boss under both part numbers: 04235101 AND 04235201. I spoke to someone very knowledgable of the problem in Seattle at MotoI. He is now trying to find out how to deliver me a part that is sure to be the correct 15mm size. He measured the boss size of a part he had on the shelf, number 04 23 51 01, and found it to be the incorrect 16mm size. As you know, I ordered a replacement arm 04 23 52 01 from Harper's MotoGuzzi and received another fresh arm ALSO with the incorrect 16mm boss size. HOO BOY. Love them italian bikes, eh? They really SHOULD HAVE done a recall on this....................... Link to comment Share on other sites More sharing options...
gh67 Posted July 19, 2005 Share Posted July 19, 2005 They really SHOULD HAVE done a recall on this....................... 56386[/snapback] What is also unfortunate is that the average MG dealer that primarily focuses more on other bike lines (I don't consider the ones you mentioned "average") still just replaces the spring from parts stock and doesn't even know of the boss replacement. I've already had one bad experience like this when mine broke the first time. Link to comment Share on other sites More sharing options...
al_roethlisberger Posted July 19, 2005 Share Posted July 19, 2005 I have updated the FAQ with this new, but confusing information al Link to comment Share on other sites More sharing options...
dbdicker Posted July 21, 2005 Author Share Posted July 21, 2005 OK, listen up, let's hope this is the LAST post on this issue. Todd Haven at MPH cycles in Houston has solved the arm problem at least for us in the US. He pulled the parts list from an 02 V11 and the pawl arm had the incorrect part number: 04 23 51 01 He also has pulled the parts list for an 04 Ballabio and confirms the new part number for the correct, updated, 15mm boss arm: 01 23 51 30. Both have the same parts number for the offending spring. IT IS NOT NECESSARILY TRUE THAT IF YOU ORDER THE OLD PART NUMBER THAT YOU WILL GET THE NEW 15MM BOSS. There are old arms floating around as well as new ones with the old part number. ORDER THE ARM USING THE NEW PART NUMBER: 01 23 51 30. Todd has done a few swaps of 02's using the new arm and it has solved the trans spring problem. OK, let's hope this closes the case, at least for replacements. Meanwhile, I have spent over $300 replacing my arm with another FAULTY arm and will have to do it again, at some point, for another couple of hundred. If I didn't love the bike......................
