I'm about to pull my engine to freshen it up before race season. I too have a 2008 XCF 250. One question: is the roller retainer in the crank bearings steel or phenolic/plastic?

The outer race is steel, the bearing cage is plastic if that makes sense.. the cage and rollers came out with the first strike with a drift. Just heat the case before knocking out the outer races..

@@dofunstuff2333 thank you for the information. It makes perfect sense. It's what I expected. I didn't buy the OEM bearings. I was going to go with All Balls but the reviews said they were noisy. Hot Rods looked like they use ball bearings so I wanted to go with SKF but ended up buying F.A.G. bearings for it. They're the best I've ever used but I had a choice on retainer materials. It looked like the OEM bearings used a plastic retainer but I wasn't sure. I just wanted to know before I start tearing it down. I like to have all the replacements before I start into a job like this. Thank you again for the reply. You set my mind at ease.

How similar would this be to the 450 xcf?

hi... great video, did you only shim one side behind the new race on the crank? if so which side does ktm say to shim and which side to set up your dail caliper etc ?? im currently tearing down a 2011 xcf 250 as a project after the previous owner had run it low on oil... seized the crank but the top end looks ok.

Do you have to do that on all ktm bikes with the shimming of the crank? Working on an 08 250sxf thats getting a crank and top end and never had to that with any of the other engines from the other manufacturers. Thanks and great vids

First of all, amazing job man!! Have you got any videos disassemblying this motor? If not, let me ask you a question. To remove the crankshaft i don´t know exactly how to say it in english(cigüeñal in spanish), is any special tool needed? I´ll disassembly my old one and replace it, do i also compulsory need to replace the bearings for new ones? Thank you and sorry for my bad english.

Thanks man! Unfortunately I don't have any footage of it being disassembled. It was already apart when my friend brought it to me. If the crank is in good shape you might not need to replace bearings. Depends on the hours ridden specified in the srrvice manual.

Got the bottom end together now my question is this, should you be able to move the crank side to side a little in the crankcases. Haven't installed the flywheel or gear on crank yet

@@dofunstuff2333 yea been talking to some ktm builders, some of them say they set them at .50-.55mm, and some say they use no shims. One guy mentioned room for flexing at high rpms. So seems there is some ktm builders that don't go by the specs. Thanks you do a great job and I bought that same dial caliper you using

I would double check can timing.. That would be where I start.. Also valve lash could be too tight not allowing a valve to close..
