Cool & informative👍 Question: if the eccentric shaft is polished beyond thee allowable tolerance, is there a bearing to compensate? In a conventional engine if a crankshaft needs to be cut, then there are both main and rod bearings to compensate the cut. Found this footage interesting!..thanx👍
@@nazmazosr1260 Not strictly true, Mazda do offer different sized main bearings. However they only vary by 0.02mm. Listed by bearing thickness 1.980mm-2.000mm.
Good point but it's unintentional unlike piston engines where they intentionally oversize them, it's a matter of chance, give or take with rotary engine bearings...
Thank you!! This is extremely valuable info!
much respect !

No, unfortunately there's no such bearing. All 13b and 12A engine come standard (all one size) from Mazda.
