Wheel Pressing

[ngtmodels]

Hello,

I've got some 2.5" scale wheels and axles to assemble, and I'm wondering what 'ton' press I should be looking to buy?

10, 15, 20 ton..., ?

As you can see, it depends. My formula was figure out about what it would take, and buy the 20 anyway.

Be sure and have a little bevel on the shaft or "deburr" on the hub to get things started. I use a little grease to help things along with heavy fits. You don't want any galling.

Turning a slight step on the end of the shaft really helps line things up, more so than a bevel.. step only need to be .020 to .030 long and .0005-.001 under your bore size.. I have yet to have problems with galling or bore deformation from shafts trying to go in sideways..

i have used this on heavy equipment on bushings up to 6" dia... and yet alway be sure to use some kind of lube/antisieze product when pressing..

hope this helps someone...
