Hi everybody,
here is a little “how to do the Schlumpf”.
1, remove the bell, turn your Strida upside down, remove crank bolt and belt tension bolt
2, remove the small conical part (using the bbl tool), insert crank separator tool, screw in as far as possible and detract crank
3, insert drift punch into thread of tension bolt, remove the big groove nut and pull the excentric fitting out
4, remove the brake, remove the belt roll and the wheel, unlock your Strida carefully and change the belts
5, lock the bike, mount wheel (Loc!), belt roll (Loc!) and brake (Loc!), pull the Schlumpf in its new housing, fit the big black groove nut (do not tighten yet), and fit the belt
6, mount the single crank and tighten the axle bolt (strongly), mount the gear shift button (and shiftplates), refer to:
schlumpf.ch/hp/handbuecher/WHB.sd.engl.pdf B-4, B-5
7, adjust belt tension, tighten the belt tension bolt and the groove nut, mount pedals - done!

required tools:
-the Schlumpf tools
-Allen keys 4,5,6,8 mm
-socket wrench 14 mm with ratchet or similar
-cotter pin drive, drift punch 6 mm diameter o. s.
-crank separator tool (bblparts BTL-14 o. s.)
-bolt adhesive, thread-locking compound (Loctite o. s.)
depending on your crank separator tool:
-flat wrench 15 mm
-adjustable wrench or flat wrench 16 mm
If available, use a torque wrench to tighten the following bolts:
-brake bolts 8 Nm
-axle bolt 50-55 Nm
-gear shift button bolt 1,1 Nm
Never use any bolt adhesives or thread-locking compounds (like Loctite or similar products) on Schlumpf parts (axle bolt, gear shift button bolt, belt ring bolts)!
Always use bolt adhesives on Strida brake bolts, wheel bolts, belt roll bolts and some other parts (Loc!). Refer to Strida user manual:
strida.us/files/5-MiniManual.pdf
The procedure takes about two hours and the Strida weighs about 500 gram more now.
Stormy, rainy and ugly cold here, the driving review will take some time…
…is there anybody out there…
