awesome work!!! problem with this engine and kxf engine factory had error in manual for 12nm cam torque and it was supposed to be 9nm. stopped seizing cams when i dropped to 8-9nm and they later changed service manual because of error. i wish they came with removable/ replacable cam bearing like this

At my experience, the best matrial for bearings is a soft cast iron. Coz they have big sponge holes. It can keeps oil even they are dried. I'm used for crank shaft bearings without having any problems. And last longer. Otherwise, using cast aluminum ( i melt it from engine scrap)

Amazing work you did there. What is the reason they got broken in the first place? is it oil starvation that makes it worn out like that?
@PaulXchannel4 жыл бұрын
Thanks . The reason is to little oil.
@bevanwilson56424 жыл бұрын
Ha I have recently done the same thing though I retained the bearing shells the same way as with crankshaft brearings, an interferance fit. the camshaft wasnt badly scored and polished up fine. When I made the bearing shells I held the two halfs in a four jaw chuck in the lathe, took a couple of goes before I had a succesful outcome but it worked cheers
how much do you charge for the same procedure but on a 06 Rmz 450

I can’t understand if the bearing, after being made on the lathe is then cut through the centre, then how is that a perfect circle? What am I missing? Thanks
@PaulXchannel4 жыл бұрын
One bearing is made of two pieces. It is cut and then milled in the cylinder head into a precise semicircle.
@edwinjidat88854 жыл бұрын
Just for inform. Don't used aluminum alloys for bearings. They will stick to cast iron, coz that metal didn't have sponge holes. Thats why all engine using cast aluminum. Rather than aluminum alloy, i suggests using cast iron or bronze ( copper phosphor) they wouldn't stick to cast iron (cam shaft)

@GuerillaMovie4 күн бұрын
@@PaulXchannel for sure! Bronze is self-lubricating and more resistant than aluminum. It is currently and widely used for these purposes, practically on all car engines. Being more resistant you can make these bushings thinner. I wonder why they don't use it on these heads, now I understand why these bikes don't last so long. To be precise there is a special bronze just for these purposes if I remember correctly. If you inquire around you will find confirmation.

I think not. WARNING. There is a different thermal expansion in the aluminum cylinder head. It doesn't work well with bronze bushing.
