end float

wondering what the minimum endfloat tolerance could be on a zenoah 26 crankshaft.

Maintenance specs can be found here on Modelgasboats.com in the Ressources section under engines. Here is the link to the Zenoah Maintenance Specifications: www.modelgasboats.com/images/s..._Pics/Specs.pdf

Anything around .050 or less is pretty normal.

Specs say axial play 0.5 mm ... Thats @ .020

Seen a lot far looser than that and why i said anything less than .050 is fine IMO

the 26 zen crank is going into a set of QD 4 bearing cases to suit the zenoah jug.i hear a wisper of the crank could be a little tight in the QD cases on the end float.i realise zen recomend .020 but if i find say .010 is the number,should it be increased by pushing the webs a little closer together to get the .020,or are there other options to increase end float.i dont have the cases yet so i am jumping the gun a bit,but just getting ideas for now.mabey the crank will have correct float when installed and the wisper is only a wisper.
