Hello
layshaft end float = ? can someone descripe the part. is it relatet to the camshaft ?
To mesure out the bores and several other things you need some basic messurment tools:
Well I had the oportunity to get such tools direct from the manufactorer in Stuttgart and spend over 1000$ back then ( 1984 ). Today the same grade and quality will cost 2000 $, they prices for mechanic droped slightly but precision is allways hard to manage.
Better visit a shop with the pre mountet empty case ( tourqued down to specs ).
I do allways messure all including the delivered bearing´s : I also recomen a perun with the crankbearings in the case. You can feel any problems by turning the crank. Well lubed and oiled it shud turn smooth with no spots.
Disasembling the engine is marking all parts. Allways put them back on the same spot and direction. The slightly heavier rods and pistons go to the flywheel. The parts have diferent wightgroups and within that a tolerance from 3 - 6 grams. You also can find the lightest part and match the others by little grinding. But i hope you know how to messure the correct moving wights on the rod.
Most borespecs have tolerances from -0,008 to - -0,016 mm. say field is 0,008 mm
Crankcasebore gets oval and has sometimes undersize in piston movement direction
while geting oversize on the other driection. Just rebore to standardsize will work.
