Sorted ? the internets a wonderful thing. Thankyou everyone. Cheers Mark

Are they on the internet or phone based ?

Has anyone ever had any made, mine are de-laminating and to be honest are knackered. Keep looking for good 2nd hand ones but none popping up so considering getting some made but the cost (looks like £350/400) is seriously putting me off. Cheers Mark

Yes i have one front fork with corrosion ☹ have considered getting some yokes made but will price them up first. Its been a strange dismantle as some parts have never been apart but as its a 76 and has so little wear or damage its amazing, will enjoy the rebuild process once i get a bit more organised and save up a bit. Cheers Mark

The rust was a little worrying but its light and there was quite a coating of oil with it, there was water in the gearbox and clutch so yes i have quite a rebuild on my hands (first montesa too) the marks on the crank make me think it has been apart but many many years ago as it truly was difficult to dismantle (the barrel studs were quite a quest - and the base gasket was an original) but theres virtually no bore wear and the piston is like new(std too) So possibly it was either rebuilt years ago or its never been apart and the marks are a mystery. Searching for fork yokes too as one is very badly corroded which takes me back to the water issue, but wheel rims/frame etc have no corrosion. Cheers Mark

You bloody star ??????? thats brilliant news. Doing little jig ??

My conrod had sideways movement of over 3mm, is this normal. Clymer manual says .4 to .5 of a mm but the book does stop at 75 and i have 76 mrr. Is it spaced into position by little end ? I did run/ride it a short distance before dismantle and it ran smooth and quiet so unsure whether it need replacing or not. Just seems very odd to have such movement but nothing seems amiss apart from this 3mm sideways movement. Has anyone any ideas at to whats amiss. Engine didnt seem to have recently if ever been apart, bore+piston in excellent condition just wear on one gear, barrel nuts were very difficult to remove giving me the impression it had not been apart. Hope someone has an answer for me. Cheers Mark

Found one in the USA £20 ?

Will try and find it, when i go back im going to try n barter. Im not paying 65 its nuts ?

Was in a 2nd hand shop iin cornwall but was £65. Nearly dropped to the floor and left it, but going back down in 3wks so hope its still there

Have possibly found a clymer manual that covers up to 75, i have a 1976 (51M3194) and before i buy it as its not cheap, does anyone know if theres plenty of cross-over from 75 to 76 so that crank/gearbox etc specs are useable. Cheers Mark

My 1976 348 now currently dismantled, anyone with a manual please give me a shout, i need settings/torques esp crank. Dont want to replace rod and bearings if its in spec. Piston/bore didnt seem worn when i stripped it but piston would twist around 1 to 2 mm. Cheers Mark

My piston rotates like this around 1 to 2 mm , is this normal. I cant find any tolerance specifications for the crank/rod/piston

Currently dismantled awaiting steady restoration.

Thankyou ? had a quick peek thru and some things look different to mine (gearbox gear,s) but good to have. Cheers Mark

Thankyou ? will look him up. Need one gearbox gear as its worn at base of teeth, but need lots more inc bottom fork yoke.

sadly links not working lineaway ?

if you can find it Basil id love to buy it/borrow it, and quite happy to pay the postage. cheers Mark

just starting to dismantle my 348 (1976) and im unable to find a manual, were English ones ever available ? need one gear for gearbox too but that's only the beginning, bike is now in a million parts in my garage and its going to get expensive I can tell. Anyone in west Yorkshire with lots of knowledge would be good too. cheers Mark

have just bought a Montesa 348 Malcolm Rathmell replica, needs total restoration so in the process of dismantling, and hope there's lots of information available here as I've yet to find a manual, going to enjoy this restoration. cheers Mark
