naichuff Posted April 29, 2012 Report Share Posted April 29, 2012 The montesa manual sayes that every thing is in the R/H casebut you have to use a crankcase puller and soft hammer The parts book only has Honda numbers Both mains are the same bearings Quote Link to comment Share on other sites More sharing options...

caravan_monster Posted May 18, 2012 Report Share Posted May 18, 2012 I'm preparing to replace the mains in my 315 also. Could anyone advise on the following: Special Tools - Looks like I need to buy - a M30 flywheel puller -some sort of clutch or flywheel holder -crankcase puller -crankcase assembly tool I can have use of a press and bearing puller. Have I missed anything ? Can I do without any of these items ? Presumably ebay will be ok to source them, but are there any particular models of any of these tools that are best for price / ease of use ? Gaskets - Is it possible to buy a decent quality complete gasket set cheaper, instead of buying them all seperately from Sandifords ? Neutral Gear - it's virtually impossible to select neutral with the engine running. Is this down to wear ? Is there anything I can do about this whilst the engine is on the bench, or is it just a characteristic that I'll have to live with ? (I understand recommending suppliers is not allowed on this board, but please do PM me if you know of anywhere that can help with the above tools and / or parts) Quote Link to comment Share on other sites More sharing options...

caravan_monster Posted June 19, 2012 Report Share Posted June 19, 2012 Got the job done. Special tools needed are crankcase puller and flywheel puller - I was incorrrect above - the flywheel puller is 32mm x 1.5mm pitch l/h thread. It's an unusual size: this firm can make custom pullers. I don't think there is much advantage to buying the main bearings from an engineering shop - the expensive parts are the seals. Quote Link to comment Share on other sites More sharing options...
