What little things do I need for an engine rebuild?

Gaskets, crank seals, thread locker, stainless pipe thread sealant, harmonic balancer/ flywheel puller, flywheel holder tool and/or driveshaft coupler holder tool, piston pin removal tool. All of the special tools can be "improvised" at your own risk, but you will need to have them or figure out a substitute to complete the job.

Instead if a flywheel holder you can run a piece of rope into the cylinder closest to the flywheel. Seems to have worked fine for me anyway.

Yeah it works, until you bend the rings.


A long screw driver in the couplers is the way to go. When you tighten the bolt the motor will turn and then the screw driver will be wedged in the couplers and the end of it will hit the ground.

torque wrench, copper gasket spray and beer. lots of beer and a buddy.. i did my first build by my self and it was a pain in the ass. get a freind who knows skis to lend a hand and even if he has limited knowledge you will still get it done in half the time because there are so many little things that you just need a third hand for :crazy:

Ill most likely do most of the rebuild by myself but may get a little help.

What should i do about crank seals though? Mine look fine but i dont know how much of a tolerance there is on them to be in spec.
Also, anyone hone their cyls themselves? thats one more part im debating.

Would you put a used condom on? Change those seals!

by the way most likely you can get crank seals at your local Yamaha dealer if not call Wamiltons they could ship it ground and you would have them next day or two :biggthumpup:

wamiltons has the seals for $50, ive yet to call any local places but does anyone know of a cheaper site?

Rebuilding is expensive... I got some killer deals and still spending more then i want to be. Out of curiosity how much is a brand new 61x?

greateryamaha.com for all your Yamaha OEM needs. I believe all 3 will be just under $50

BTW , while you have the motor apart, it would be a good idea to consider a little freestyle port job. $275 = nice power gain!:arms:
