Sorry for the late thanks but top info Thanks all

Thanks cleanorbust... I was only afterr the sizes as john lee motorcycles is 200 yards away from home and Charlie said get me the sizes and by us a pint an ill sort them for you lol ... I've just ordered the main bearing thanks again. Pinion a problem then?

I'm about to split the crank case on my 1974 247 montesa would anyone know what seals and size are needed and should I replace anything else while its apart..

Thanks thinking about would it be better to buy a matching pair of crankcase as I thought back in the day they got built as a match pair or would it be better just to get my original one repair?

Gents thanks for all your feedback, Shaun I have the engine out now and will strip it down over the weekend (should be tiling the kitchen but hay!! ) and check all is in order over the rest of engine, need to replace the l/h crankcase so will check as I'm going along. Anything unusual I should look out for when splitting the case ?

I have acquired a 1974 ish 247, it has a part of the crankcase missING between the magneto and the kick-start which I believe is a common problem. When I was in the process of removing the flywheel I took the other side crankcase cover off and found this inside. Before I start pulling stuff apart could anyone enlighten me where it might have come from.. Thanks Ian

Hi Just got a 247 Montesa and new to classic trials, the old girl I got needs a bit of loving and would value the help of more technical people then myself. Ian
