Montesa301 Posted Tuesday at 03:43 PM Author Share Posted Tuesday at 03:43 PM I had it apart again today and it had pushed itself out again. I have heard of people machining a grub screw in to hold it but I’m not brave enough to attempt that! Quote Link to comment Share on other sites More sharing options...
sportsawyer Posted yesterday at 04:46 PM Share Posted yesterday at 04:46 PM (edited) I believe it's the smaller gear (behind the primary gear), which meshes with the kickstart idler gear, that backs out. Mitani has a writeup about it here: http://mitani-ms.jp/info/2013/09/rtl-f-clatch-outer/ It's in Japanese, but my browser did a good enough job of translation to get the idea. Mitani makes an improved part, but it's not clear how they improve it: https://mitani-kobe.shop-pro.jp/?pid=60396201 Edited yesterday at 04:51 PM by sportsawyer Clarification Quote Link to comment Share on other sites More sharing options...

Perhaps something like LOCTITE 270 anaerobic permanent adhesive could help or a strong bearing retaining anaerobic adhesive. such as LOCTITE 638 Edited 3 hours ago by Tr1AL Quote Link to comment Share on other sites More sharing options...
jrsunt Posted 2 hours ago Share Posted 2 hours ago Shouldn’t have come apart like that. A new one won’t be cheap but a 2nd hand one may be worth a try. I would think Richard Allen trials spares would have some. If you’re really stuck I have one on a spare engine. Quote Link to comment Share on other sites More sharing options...

I know who you are and that you are a serious rider on Honda machinery and therefore know what you are talking about but Mitani who have pretty good knowledge of the Honda motors engineering wise reckon this movement can happen in approx 1 year of use. With the amount of torque the motor produces and the abrupt use of clutches in trials sections ,as happens, then an interference fit steel part in a softer aluminium outer part is going to start twisting and enlarging the alloy part in the same way that the rivet holes on the clutch bell elongate in the end and give rise to slop. I am happy to go with Mitanis' view based on engineering. Quote Link to comment Share on other sites More sharing options...

As that is the case you know what your options are so its a closed case. I am talking to myself of course.
