Side Plate Resurfacing or Surface Grinding
Side plate surface finish, flatness and hardness are
critical for the performance and reliability of a rotary
engine.
Over the life span of a rotary engine the side,
corner and oil seals wear a path into the working face
of the side plates, leaving an uneven surface for new
seals to travel and bed in. This can cause premature
wear or breakage of seals and also prolonged run in time
as sealing will not be optimal.
The maximum wear acceptable
on a side plate surface is .0030"
Also over-tightening
of the gearbox, front cover and water pump bolts can
distort the mating surfaces and cause misalignment
and added stresses on bearings and friction surfaces.
To rectify this the side plates can be resurfaced. A
process where the plate is set up square on a surface
grinder and precisely ground, taking only the minimal
amount off the surface. Both sides of the plates are
ground to eliminate any scoring or distortion and return
the plate to a truly square and flat working surface.
All
dowels and pins are removed prior and replaced after
resurfacing.
Plate may need re-nitriding if surface grinding has been
conducted before or wear grooves are beyond tolerances.
See Re-nitriding section
of “Side plate resurfacing”.
A charge will be incurred
if plates are not stripped, cleaned and gaskets or sealants
removed prior to arrival at our workshop.
