Stator Crankcase Cover Gasket

Aprilia Tuono 1000 V4 and RSV4 2009-2017 · Tuono 1100 V4 2016-2017

This is a brand new stator crankcase cover gasket, part number RMS050-103753, made for the Aprilia Tuono 1000 V4 and RSV4 from 2009 to 2017 and the Tuono 1100 V4 of 2016 and 2017. It cross references to Aprilia 2D000049, 897479 and 1A010574. The gasket seals the joint between the stator cover and the crankcase, keeping engine oil inside the cover where the stator and rotor run.

This is the part you need whenever the stator cover comes off: replacing a failed stator, fitting a new flywheel rotor, tracing a charging fault, or curing an oil weep from the cover seam. A crankcase cover gasket is a single use item. Once it has been torqued down and taken a few hundred heat cycles it has set to the shape of that joint, and refitting a used one is the usual reason a freshly rebuilt cover starts seeping within a few hundred miles.

Fitting is simple with the cover removed. Scrape both mating faces completely clean so no fragments of the old gasket are left behind, lay the new gasket dry unless the workshop manual for your model calls for a sealant, and tighten the cover bolts evenly in a criss-cross pattern to the manual torque figure. All item pictures are accurate; if in doubt, compare the item against your original part before fitting. Ensure proper installation by a qualified technician to avoid malfunction.
