ID:	231054Finally found some time to start pulling my bottom end apart. Looks like I'm in to deep now. Funny I said that. I've been out of town for 8 months for work, only home on the weekend. m.youtube.com/watch?v=WVtRyrOaoZA

    I will be needing some help on this one. I believe I have already downloaded the manual. I'll have to check. Looks like I need a special tool for the nut in the piece above the oil pump. Not sure what you call it.

    Yes, you need the manual. It will tell you EXACTLY what you need to do it and exactly how to do it all. Piece by piece. I just did mine and it was my first time as well. And if it wasnt for the manual, theres no way in hell i wouldve been able to do it. You MUST use it if youve never done it before. And this is the "special tool"
    You need it for your clutch and oil pump rotor
    http://www.amazon.com/gp/aw/d/B00CRH...P8L&ref=plSrch will fit into a 1/2 drive ratchet and youll need an extension as well. At least i did.

    Cool deal. Thanks. Just got the flywheel off with 14mmx1.5 bolt. The spanner nut tool looks like a must at that price.Click image for larger version.

    You can make one if you dont wanna wait for it to ship. Alot of guys here have. Just sacrifice a socket and use a grinder to cut it how you need

ID:	231133 Found an extra socket laying around. I used a 7/8" socket, it fits real good. I appreciate the link though.

    I got my crankshaft out. The 7/8" socket worked perfectly. Now for the bearings. I am gonna have to get some of those. Weisco 65.5mm 10.25:1 piston on order, bottom and top end gaskets too. I have been looking at some threads here on the forum about the Kickstart gears slipping. Some guys were back cutting the gears. I may go for this mod as it seams fairly simple, since it's apart. As for the bearings in the third pic the bearing on the right seams sticky. Is there anyplace that sells a full set of bearings, or should I just replace as needed?

    My piston showed up today. I am excited to get it and my cylinder to John Tice. His shop is close by my work.

    I am wondering if anyone knows a good source for these bearings. Or can I just order from any bearing manufacturer.

    Last 200x I built I had to look hard for some of the needle bearings. Most of the roller bearings are still easily obtainable. If you can't find the needles you may have to take the old ones to a bearing mfg.

    I'm hoping its just the one bearing in one of my above pics. It's a little sticky.

    If you are referring to just the bearings in the pic above then those should be readily available. Now that you have the cases torn down this far, I would replace as many as you can. Sticky or not, they are 30 years old and likely need some attention.
