montesa pierre Posted April 30 Report Share Posted April 30 I have a 1981 Montesa 248 Cota. Engine No 21 M 51176. I need to replace the right hand timing case. I have looked at the parts manual and it indicate just a timing cover with a plastic chain guard above the front sprocket. The cover fitted to my engine is the whole length of the right hand crankcase and originally covered the front sprocket. It has a cut out at the front which perfectly matches the rubber grommet where the ignition leads exits. Does anyone Knows what Montesa model this timing cover comes from ?. The retaining screws all line up perfectly and the casing has the Montesa motif on it. Before I remove the damaged part are there any internal numbers that may assist.

dr nosh Posted May 1 Report Share Posted May 1 I think that the cover you describe will fit the earlier 247 models. My 1982 248 looks like this on the drive side Quote Link to comment Share on other sites More sharing options...
montesa pierre Posted May 1 Author Report Share Posted May 1 Thank you for our reply. Unfortunately your photograph show the correct type of timing cover. My cover is the whole length of the right hand crankcase, covering the drive sprocket. I think a photograph of mine would be an advantage to identify it Thank you, Peter Lee (Cornwall) Quote Link to comment Share on other sites More sharing options...
barnesy Posted May 2 Report Share Posted May 2 You may have a 348 cover on your bike that has been cut down as they are the same dimensions... Quote Link to comment Share on other sites More sharing options...
