Gearbox is out

[(RIP) maverick]

So warmer weather this morning and thought might as well attempt to see what's wrong with the bike.
Started stripping untill I got down to the bare minumum of frame, gearbox and motor

 

[(RIP) maverick]

So the offending piece of technical engineering this time around is

Bloomin heck Maverick, hope it all goes well for you.

So the Steptoe team 1-0 congrats!! Luckilly the splines on the gearbox still seem to look in order. Now purely a case of getting the clutch kit and installing it properly

Hey Richie if it does not your'e invited to the first South-African GS bbq mate

The first time in my life I have seen splines stripped off like that and still amazed and My main worry is not getting it all back together again but mentally wondering if this scenario will happen again down the line and how can I prevent it except by selling the bike

clutch

How did you manage not to bend your pushrod with all that extra weight on the back of the gearbox when pulling it off from the engine was it easier leaving the wheel/shaft in place?judging by how dry your splines on the shaft look I would not be surprised if this has something to do the premature wear on the clutch plate splines.If you don't know when the shaft and bevel was last greased I would definetly pull it out to have a look just to be sure,just a suggestion.Andy

Hi Andy, no mate south-africans are just very fekin strong , my appy(Michelle) held the subframe in the air while I pulled the whole unit out with ease (thanks for the tip Neil)

Believe it or not I did grease up every single spline(white spline grease) and bolt(coppergrease) when I changed the gearbox in February before going to Germany. What happened to the grease I would not know??

I will how ever make sure there is more than ample grease and whatever needs to be done on all bolts/splines/washers when re-installing the bugger again.

Thanks for the tips

grease

this is what you want for clutch splines not white paste.

 

[andy malton]

white paste

Your white paste probably melted and was flung off due to the higher temprature produced by being nearer the engine.White is fine for the shaft/bevel because you don't have the heat there!the LM47 has higher melting point.Andy

grease

Available from motorworks about £6 I think,and yes it's bmw recommended.

 

[Steptoe]

what did i tell you, seen it many many times; don't spend a fortune on grease; molybdenum disulphide grease ( Moly grease) big tub about £5 - used it on clutch / drive shaft splines on 100's of bikes over the years ; no need to grease drive shaft splines, thats only on K's; do you want to use my aligning tool , the splines look a bit worn, i'll see if i've a better input shaft you can have;

 

[Mick Fagan]

The voice of experience here!

If you overload the input shaft splines with any kind of lubricant, I'm pretty certain that you'll find, after initial takeoff and a short trip, excess grease will be flung outwards and onto the clutch and pressure plates.

This has the disconcerting effect of making the clutch stick like xxxx to a blanket and then it lets go and all hell breaks loose in the gearbox.

In short, lubricate the male and female splines, just don't overdo it!

Mick.
