ok here is the rotors,as you can see the side seals come longer so you can file them back to the clearance you want....this takes ages,my view this is the part that can make or break the engines reliability(not just side seals but all the clearances as there are many others)
these are the oil control rings that stops the oil that flows through the centre of the rotor entering the combustion chamber,the oil lubes the centre bearing and cools the rotor itself.The oil control ring is metal with an o ring that fits inside the outer ring and inside the inside ring
rotaries get built from the front to the back so we start with the front plate,fit the stationary gear(which has also been carefully clearanced)
aftre being bent over from both nissan and mazda i have lots of vaseline left so coat the front plate with it
then prep up the front of the first rotor by fitting all the seals and springs,the corner seals have tiny springs under them,as do the side seals and oil control rings
here is the front rotor covered is vas ready to be dropped onto the front plate
then fit the backside of the front rotor with all the same gear
and your ready for the housing,these rubber bands are a sort of head gasket.The inner one is made of some strange heat proof material as the combustion heat and gas give it a hard time
the join part of it goes near the intake
i like to use threebond in the groove
then drop the housing on and fit the dowls in
this is the apex seal and sring
and slide them down the corner of the rotor
next drop on the centre plate,insert e shaft/rotor housing and build up the next rotor then rear housing/tension bolts and the core is finished
