Saabdriver Posted October 20 Report Share Posted October 20 Anybody that can share some light on this I will be most grateful. I have a 1981 Cota 349, well I think I do ( engine number 51M18349 ), I bought it as a rolling chassis and the engine in boxes. So far I have gone through the Montesa parts manual and found all the missing bits with the exception of 2 parts. Now these don't appear in the Montesa manual one usually gets online, and the difference seems to be my front sprocket is of the splined type and not the usual taper fit with a locking nut. To hold the front sprocket in place there is a sort of sprung cup and a clip which sits in a groove on the end of the output shaft. the clip on mine is broken in two pieces. The cup is tatty and I would like to replace that as well. Now as I don't know the part numbers I don't know where to start looking. I have tried the usual parts suppliers here and in Spain but nothing looks like what I am after . Was this system of securing the front sprocket used on any other Montesa models perhaps ? Many thanks in advance, Quote Link to comment Share on other sites More sharing options...
mcman56 Posted October 21 Report Share Posted October 21 (edited) What you are describing sounds a little like this but Honda did not buy Montesa until later. TL250 Edited October 21 by mcman56 Quote Link to comment Share on other sites More sharing options...
Saabdriver Posted October 21 Author Report Share Posted October 21 Thanks for the suggestion. It would appear that the same system is used on the 360 Enduro model. I have found the part number and ordered said part. Sadly the.only supplier was in the USA so postage is eyewatering ! Thanks again for your suggestion. Regards. Gareth.

cleanorbust Posted October 26 Report Share Posted October 26 Glad you've found a solution, even if it's costly. If I were you I'd just be glad you're not lumbered with the taper fit sprocket type, which are usually an absolute swine to remove after several years of being seized in position!

Saabdriver Posted October 27 Author Report Share Posted October 27 Yes I have heard many horror stories of taper fit sprockets. I watched a Spanish youtube video of a 247 rebuild and saw what a struggle it can be Thanks for your comments. Regards, Saabdriver 1 Quote Link to comment Share on other sites More sharing options...
