New main crank bearings installed
Was able to remove the old seals and bearings for the crank and replace them with new ones. I had to heat the case halves to about 150 degrees with a propane torch.. after that, the original bearings fell out. I then took the new bearings which were in the freezer overnight and they dropped right into place :ride:

I used a similar trick when putting on the timing chain or my 66 Mustang...cool.
Nice and clean...looks ready to get it dirty again. do the bearings require grease or will the gear oil suffice? Ken |

http://www.ism409.com/images/ktmrebuild/rebuild_22.jpg another crank shot http://www.ism409.com/images/ktmrebuild/rebuild_23.jpg This is the old rod.. you are not supposed to see any gap there.. this thing is toast. http://www.ism409.com/images/ktmrebuild/rebuild_24.jpg You can see the bearing was starting to attach to the rod. http://www.ism409.com/images/ktmrebuild/rebuild_25.jpg I'll be putting this in tonight! :nod2: |

I got the crank back into the cases and put the bottom end back together. Before mounting the engine back into the frame, I fixed my outer clutch basket. It was grooved pretty bad which would catch the clutch plates and never let it fully disengage. For example, it would slightly creep on me in 1st gear with the clutch pulled in and it was also hard to kick over while in gear. I have to mill off a couple .001" or so to get the basket all smooth again. This should be good for another season or two. For now, it also saves me $200 (price of a new one) Here are the pics of the refreshed basket. http://www.ism409.com/images/ktmrebuild/rebuild_26.jpg http://www.ism409.com/images/ktmrebuild/rebuild_27.jpg |

I totally slacked on taking pics of putting it back together but it is back together and on Saturday it started up 2nd kick!!!! :drink:
I rode it the piss out of it on Sunday! - new parts/crank rebuild = $600 - new tools = $50 - hours spent working on it..I lost count - paying ZERO for labor and rebuilding the whole engine by myself....PRICELESS!!!!! :nod2: |
