In this video I will be building my YZ125 engine from the case up. Starting with all the bearings including Transmission, main bearings etc. From there we will install the crank shaft, transmission shaft and shift fork assembly. To end off the video we will be mating the two case halves. Thank you for Watching! Please subscribe.

Putting together a 02' YZ125. With gear shafts, forks, and cam installed, I test fitted the other case half to test gears. It keeps getting locked on the dogs. Though the gear cycle. Do the gears on shafts 1&2 need to be timed or something. Wanna make sure before I install crank.

@RecreationWerx 3 года назад

Make sure you have everything lubricated and you spin the shafts while going through the gears

@stephenflynn4803 3 года назад

Also, did you coat the steel parts in any kind of light oil during re-assembly? Thx

@RecreationWerx 3 года назад

Yup use some mixing oil or transmission oil as assembly oil. I use both depending on the part

@stephenflynn4803 3 года назад

What is cerakote and how long did you bake the cases and at what temp? Thanks for the excellent video😀

@RecreationWerx 3 года назад

Cerakote is a coating company that specializes in durable thin coating that have high chemical and heat tolerance. You can check out their website! I pre heat the cases in the oven for 1 hour then apply coating. Then bake again for a full hour.

@dr00andrew 3 года назад

the cylindrical bearings at 2:57 you installed, were the stamped letters on the race facing up towards you or down into the case?

@RecreationWerx 3 года назад

Stamped letters are facing up towards me

@dr00andrew 3 года назад

@randomguy1807 3 года назад

I see you hit the bearing in with the socket on the inner race? Is that a bad thing to do? I did that today and am worried it wrecked the bearing.

@RecreationWerx 3 года назад

As long as you are careful and use the right size socket you can feel the difference in the taps once the bearing is seated. I prefer to use a light weight brass hammer or a plastic hammer.

@fabyanjim1 2 года назад

Never and i repeat never hit the inner race to install a bearing. The correct way would to find something the same size as the outer race thats where u apply pressure hits etc.

What year is this YZ?

@georgesparrow100 3 года назад

Wicked video, could use this a step by step. What oil do you to put in seals and/or bearings?

@RecreationWerx 3 года назад

Thanks dude! I’ll use what oil will be on that part when running so on the trans bearings and stuff I’ll use trans oil and on the main bearings/ seals and piston I’ll use my pre mix oil. Yamalube 2R

Alex Tucker ahhh that makes sense, thanks!
