Always had mine done at Engineering / Machine shops & not that expensive.

They're easy enough to get out. I had a tool made up to fit my new bearings in

 

[beaubrad]

Oooh could you please show sam:D

[beaubrad]

Good read thankyou, just need someone to show me how to make a tool to do it??

[Ethel]

It's rare that they need replacing (though I suppose all blocks will be expected to last longer now), I too would leave it up to a machine shop, you're often using one anyway if you've stripped an engine down for overhaul. It's much easier to set things true if you have a mill, or similar, for a datum.

 

Sam's tool looks to be a length of threaded rod with some appropriately sized collars.

[Sam]

Yes, making the tool itself isn't exactly a DIY job as the collars were made on a lathe. 

[mini13]

Yep,

 

bit of ally in a lathe, turn it to about 10 thou less than the hole in the block, then turn a cam bearings width down to about 10thou less than the cam journel, drill a hole up it and part it off so theres abmout 5mm of the larger step on it... then repeat for the other 2 bearings...

[beaubrad]

Ah.......i see....gutting

[beaubrad]

Surely I can find something that would work?? What are the size's??

[Ivor Badger]

Fortunately you are doing them on a mini. Thus you can use the cone compresser as a puller to pull the new bearings into place.
