Matty,Thanks for all your work to make these tools.They should serve me well in my shop.

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!
 
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
