Hello everyone - since we are in lockdown - with lots of free time at hand - we decided to document some of the work we are doing, in this case a cultus's gearbox overhaul / re seal etc...
I don't have pics of every step of the way but will try to explain in detail. nonetheless, this is not a tutorial - use this thread at your own risk. thanks
so - we start by removing this chamber, you need 10mm/12mm Ts for this operation:
which leads you here:
moving on, see the labelled picture below - you need a flat faced pin to push the pin lock in (it comes out the opp side) marked YELLOW
then you need to undo the hex bolt marked PURPLE, it has a ball inside keep these safe. many more balls to come yet.
the light blue marks are circlip locks, which need to be removed to remove this fork with gear and synch assy.
Marked in green is a 27mm nut which needs to be undone. I use a impact gun for this job, if you dont have one you can shove a piece of wood between the gears to make the nut loose.
once you're done you should see something like this:
Also, please note that the assemblies are neat and clean - this is because we didnt actually take pics during disassembly. I'm just using the pics we have to explain.
this is it for today.
once you have removed the entire 5th gear assy, you should see a needle bearing as shown in the pic below: - mark its top / joint - this will make sure you put it back as it was. if you look closely, you can see the white markers
next is to remove those philip head screws 6x and the case plate - there is a bearing shim (marked green ) underneath the plate make sure to keep it safe (it may or may not be re-used, depending on the bearing play) - to end up like this:
