    If you use the mikes filter fashion a sheet metal cover for the end cuz it tears just like the stockers do, DUH!

    On your oil pump screws, you might not be able to use Allen heads. On my 75 the Allen's stuck up too much and hit the gears.

    I may have to order some. I have to go to the next town for True Value and they have very little in metric hardware. I want button heads with socket.

    I’m considering right now whether to table this for a while. The only space I have for doing a tear down is the kitchen. Robin won’t appreciate that. Meanwhile, I should start working on a space. Obviously, I’m dealing with some ferrous metal.

    Yep, what it looked like to me. I bet all of that is coming from the starter gear train. Probably find a lot of "metal meal" in the bottom of the cases. I had a lot of that on teardown but trans bearings, gears and crank bearings were perfect so... Pulling the clutch case will tell you a lot.

    There is a hole, about 1/4” diameter at 10 o’clock where the kickstart assembly goes in. I assume a pin goes in that hole. Since it isn’t here, I believe it was missing. I can’t find it in the parts catalog. Am I correct that there should be a pin?

    I'm trying to get an actual pix of that area. It looks like the thrust washer that goes over the shaft and against the case was missing too? Does not show to be a pin in that hole. Your gear looks a lot better than I thought it would be.

    oops, my bad. Not the gear I'm thinking about. It's the one behind the starter "Bendix" gear that "should" be worn and hopefully where the metal came from.

    Bad pix from my book.

    On your motor, Look to the right of the red arrow, the bigger gear. Look to the top of the gear at about 1 o:clock. You should be able to see the wear on the gear teeth.

    As far as I know, there's no pin that goes in that hole, it's just a hole and I'm not sure what it's for, if anything.

    Will I learn anything from removing the starter and cover #23? Or, should I leave well enough alone until I can make some shop space and pull the engine?

    That washer is not shown. I would expect a washer rather than pressing against aluminum.

    Hex head bolts fit, or at least they appear to fit with clearance.

    No, you won't learn anything about the kicker by pulling any of the electric starter parts.

    As far as I know, there's no thrust washer on the kicker shaft, just the wide flange at the bottom where the #1 is pointing in the drawing .....

    I'm gona have to back up. 5Twins will probably give an "amen". The thrust washer is on the outer end of the shaft and against the inside of the case. The kick start assy just sticks in the hole at the right clock position. The lug/stop on the inner side should be at about 4 oclock and the shaft should go all the way in. Then
    No, won't learn much. The starter stub sticks in thru the back. That case seal for the starter will need replacing. If you pull the cover, the shaft # 22 may stay in the cover or the case. Also have to keep an eye on # 15 and 16.

    Only a suggestion, but I bought the book, "The Yamaha XS 650 Engine", including the electrical system, by Hans J. Pahl. I think it's about 32 bucks at amazon. I use it with my Clymers. (It's a Pix book for mechs'.) I found it was worth every penny. ( Don't remember where I heard about it at, maybe here on this site?)

    So, I need to get busy clearing the crap out of the garage so I can pull the engine and split the case.

    5 more bikes in the garage to piddle with. My 83 Special needs loving.

    Been ponderin' this Marty. Sumpin's not adding up. Sump screen is (relatively) clean. Next stop (for the oil) is the pump. That appears (at least from the pics) to be in pretty good shape. From the pump, oil goes to the side screen... where there's some pretty impressive chunks of iron or steel. There's no way those bits went through the sump screen and the pump without leaving any evidence of damage. It's kinda baffling... :umm:

    You got that right. I've found nothing but very fine schwarf in the bottom, and not much of that.

    What do you think the odds are that the engine was previously damaged, repaired and no one ever bothered to clean the side filter?
    I'd almost be tempted to put it together and run it. see what kinda noise it makes and look at the screens again after an hour or two of running.
