Wiseco 67.5mm Piston

Cherokee · May 21, 2018

Just want to confirm piston/cylinder clearance for a Wiseco 67.5mm piston. Manual says 0.0014 - 0.0016 Does this measurement also apply for a forged piston?

Manual shows clearance for a cast piston. There should be a sheet with clearance per inch of piston.
Generally speaking a forged piston (such as Wiseco) needs .001" more clearance.
Hope you're putting that new piston in a new bore.

Yes I am.. just making sure the clearance is good. I got a new piston and cylinder on my trade and now that everything is completely apart just making sure everything is good.
