Where can one get a set of main bearings for the CX or is there an alternative part one can use?

You will have to try Honda dealers.



Why do you need them?Are you talking about,"Main" bearings or Big-end bearings/shells?



Also update you profile with the year and model of your bike and your location as it will affect the answers.

Nope, the 2 main crank bearings, I have the conrod bearing shells, that was easy enough to get.



I'm replacing everything as the engine is completely in pieces so every seal and bearing is being replaced, from the engine to the frame. Bike is 30 years old now, 78 000km and the stator and CDI are shot so, have replaced with the GL stator and Ignitech ECU. Bike should be good for another 30 years.



Just trying to see if there is an off the shelf car part I can use, and old mechanic said there are guys who machine out the casing and replace with roller bearings but I want to avoid that, want to keep the bike stock standard with all original parts from the OEM.

Just did thanks



So far I have sourced all my parts from the UK, USA and Netherlands, local is a waste of time as the market is very small in South Africa.

If the white linings of the Main bearing shells are good I wouldn't bother changing them.They rarely go and don't receive the hammering that Big-end shells get.If you think about it crank just sits balanced in them and rotates and never gets the ignition impact that big-end shells get.



I only know of UK/Euro sources like possibly John Oldfield,



http://www.johnoldfield.co.uk/



and possibly David Silvers



http://www.davidsilverspares.co.uk/



Both would require contacting as they don't always show everything they have).



Also CMS,



http://www.cmsnl.com/search.php?s_name=cx500



You would also need the correct information to get the correct colour coded shells.



Note:both my CX500 engines have been reclaimed from high mileage engines using 2nd hand professionally checked(Yellow pages engine specialists) and machine polished cranks/Rods with new big-end shells but re-using the original Main bearing shells.

Knowing these engines as I do I am 99% certain the Main bearing shells will outlast the cranks most likely 4 fold which could be as much as 600,000 miles as some examples of well maintained CX/GL500s have easily done 150,000 miles on the original cranks and some even over 200,000 miles and still going.



Also I run my engines with a Moly based engine additive to help prevent wear,

NO clutch slip!

Thanks



I've sourced most parts from Davidspares, very nice guys to deal with and CMSNL from the Netherlands, takes less than a week to get the parts to South Afrcia, not even the dealers here can beat that.




I'll try the other guys you recommend.

John Oldfield has to charge a little more as he's only a small family concern but he does keep some really obscure parts and if ever you can talk to him it's worth the money just to chat with him.His knowledge of Classic Hondas/Bikes is remarkable and he's an absolute gent




Remember also for International calls there are some cheap ways of doing it.

Also if you have some decent car motor factors you could always pick their brains and see if there are some car shells for the job.Shells are shells and many are stock items.It just takes time and research to find them and they may have to be slightly adapted.

Would this be a bad time to say that I'm looking for a set of main bearings, black or blue, also in RSA? :(

a reputable engine rebuilder will be able to supply you the bearings you need , even if they have to modify some from another vehicle. Its what they do for a living , so my first port of call would be to the engine rebuilder with the best reputation in your area.

Ye I reckon you guys are spot on.

I have bought the one I 'found' in the UK and will wait for it to arrive, then take it to the engineers and see if there is something that can be matched up to it!
