crank seals
Typical...rebuilt the top end 3 months ago & now the crank seals have just given up! Can they be extracted & new ones installed without having to split the cases? The bottom end/mains etc all seems fine but if the motor has to come out & split then it`s just aswell i rebuild the bottom end while everything`s apart, trouble is money is a little tight at the moment

I have seen plenty of bikes that have had their seals replaced and not needed crank bearings plus gave many more years of service. Hell, the seals on my 200 started leaking which is why I planned my rebuild. When I pulled it apart the crank bearings were still in excellent shape and the same with rod big end and all the bearings/bushings in the transmission. All it really needed was the crank seals. Yes, I bought all new everything but I sure could have saved a bunch and a lot of hassle if it was an easier to service design.

I have seen a thread some time ago where someone milled off the stops and tapped some holes for some removable stops to be attached so you could remove the seals from the outside. I have yet to see a leaking crank seal that didn't have a bearing with excessive play behind it. Seems silly to change the seals and not fix the cause of the problem. I'm not sure what qualifies as "plenty of bikes" or "years of service". Either way, I don't buy it.

So, you're calling me a liar? Really? Have I ever given reason to doubt my word? Please don't start acting like the A-holes over at DirtRider where you are the only one who is right and all others are idiots, please.juliend wrote:I have yet to see a leaking crank seal that didn't have a bearing with excessive play behind it.

BTW, "Plenty of bikes means" more than three IMO. Also, "years" means more than one year.

took the flywheel cover off today & noticed a tiny bit of oil in the housing so i wiped it away then fired the bike up...she started ok & began to idle without any problem...i sprayed some carb cleaner in & around the flywheel & the rpm did not increase?? also i inspected the gearbox level & it dosent appear to have dropped (i will change it & inspect for fuel contamination) i will take the bike for a small ride then remove the flywheel cover & inspect again...could my seals have dried up a little while the bike was sat about,now after the bike is being used again they maybe on the way out or perhaps they may begin settle down again??

Not at all man. I'm just stating my experience, nothing more nothing less. If you've had better experience with main bearings than me, that's great. I honestly think it's a VERY good idea to change the main bearings any time you are replacing the seals, that's all.SS109 wrote:So, you're calling me a liar? Really?

OK, I'm glad what I read is not what I read it to be. Don't scare me like that!
