Ktm sx-f 350 - repair of the damaged cylinder head. Double plain bearings on camshaft.

Really nice work Paul. Your editing and camera angles are also top notch in this video. Machining + engines/auto/moto = doesn't get any better!

[@PaulXchannel]

Thanks

[@4thdimensiontravels855]

1st time ever!!! A guy that properly uses a torque wrench. One non stop motion til you reach the correct value. Great work

[@dirtygarageguy]

That is complete bollocks. Period. Who told you that crap?

[@fatfightingbros9639]

@@dirtygarageguy lol the only reason most people don’t do one full motion is because they working in tight spaces, you’ll still get an accurate reading using the right tools

[@kstinson]

I certainly agree this is good practice due to the fact the clicker wrenches do give false readings when bounced. The shock loading from bouncing causes the clicker tab to be more easily over come from users perspective letting out a audible click before reaching the desired torque value. That being said though, as others have pointed out; if the wrench is in good working order and no design flaw is present preventing it, the click tab will reset into the pivot pin. So on the next pull the wrench it will have been reset and able to obtain the proper torque value.

[@darronceurter3706]

Do you have a website? I would like to have this done, my bike needs this done.

Sad part of this is that the factory if to blame for the problem here. If they didn't use plastic oil pump gears the problem would've been so common. I am rebuilding my 350 for the 2nd time because the shop that did the first one used the plastic oil pump gear that was available.

[@toddcarlo6464]

I just had the oil pump drive idler gear pringle. Head needs this very repair done. How can I get in touch?

[@ScottHorban]

Very nice ! The one big issue with the KTM/ Husky /GG 350s and 250s . Cam journal grind damage ! Even with the 2015 and older 350s that had the big #1 journal bearings . Thinking of trying a Nikasil plating on the aluminum ? Seems like it would give it less resistance /slickness with the oil passages etc. Heat and hardness should be a bit better ? What do you think ?

This method of repair has proven itself.

How much does this repair typically cost? I unfortunately have the same issue with my Husky 350 head, however the plain bearings have worn significantly more into the head an cam bridge, I think the head may be beyond repair, however after watching this video it has made me think differently.

[@andreasborsiin3967]

Thanks for an excellent video. Is there a reason to use aluminium instead of a more common plain bearing material like bronze or is it what was found in the garage?

[@PaulXchannel]

Thanks . The camshaft normally rotates in the cylinder head which is made of aluminium. Bronze has a different thermal expansion than aluminum.

[@speedphreax]

As always nice work! Why do you put those large screws in? I know that they are to keep the bearings from spinning and that they are on the non load bearing side but would it not be an idea to put a small hardened locating dowel in the head that does not break the surface of the bearing?

[@PaulXchannel]

Thanks. It is better when milling the surface.

[@realpremier]

Does this work? No hardening needed? Cheers

Not

Why not tig weld aluminum on it and then machine it instead of making suplements?

[@PaulXchannel]

For thermal deformations.

[@vcnt_mr]

If you want to fix the bolts with temperature you need to use other metal glue. Loctite have a stronger metal glue. It’s green and you need 250° C to remove it.
