    Happy to help! Let me know if you have any questions!

    Just made 20 sleeves from blanks on the old lathe. Right now the thing that is limiting stock is the m14 rod. I think I have 5 left ...so 5 kits are in stock.

    Plenty of 660 individual kits though :)

    This is a great kit and in my opinion is a must have if your doing bottom end work. I just did bearings on a ms660 and it made it a pleasant job to do. Another added bonus is you can accurately and effortlessly get the crank centered in the case. Well worth the money to have the proper tools for the job. Thanks again mattyo!

    I have a pile of blanks I'm going to be delivering to the machinist this week. But it'll still be a couple more weeks before I have stock again.
    I'm trying to stay on top of all this!

    Do you have a 372 kits available? It would be nice to have a tool to replace bearings and seals if they ever go out.

    Matty's kit works excellent. You can place the crank exactly where you want it with ease. You won't be disappointed.

    Main kits are sold out

    My machinist says 3 to 4 weeks lead time for more....so I'm back in preorder phase.

    I do have 372 and 660 specific kits in stock though

    I’m not sure how I lived without this tool. I’m serious.

    No more scrambling for the hammer while the wrong parts are cooling down or heating up.

    Highly recommend it.

    Thanks Al .. glad you are liking these!

    I do intend to stock these indefinitely. My machinist is now able to do these on CNC by threadmilling but I have to order literally hundreds at a time.

    This has been quite the project for sure!

    I've had a few guys make some mistakes (misuse these) so there are a few quick tips that help..

    1, these are not intended to pull bearings into pockets. install the bearings however you like in the crankcase halves first, THEN grab these tools to pull the crank through the bearings
    2, the main kit comes with 2 sleeves, small and large. use the large sleeve for large bearings, if you use the small sleeve, with large bearings (and therefore large crank), you'll swage the small sleeve larger. don't do that. i've had a few guys get their small sleeves stuck on cranks that have 6203 bearings.

    that said, i love using these. i never sweat splitting a crankcase anymore because I know it'll be a snap to get it back together :)

    The smaller rod for stopping rotation of the main shaft tends to bend. Any ideas of offering this one part in a tempered version?

    It still works, but mine is certainly an arc by now.

    I think he should ditch the small one, and machine the larger one down on the end and rethread it for the smaller sleeve. two would be supplied, the original larger one and a larger one thats been machined down and rethreaded at the end. I don't think that small area machined down would bend with it being so short, but who knows
