I made this at work today. I had to pull the mains off the spare block I have to remove the crankshaft. This worked very well. I got it part of the way out by turning down the bolt and adding washers as it bottomed out. I then flipped it over and used it like a slide hammer to pull out. These were so tight and I assume they must have to be pressed in. This is a great little tool.

Two things still to figure out are, how to get out the cam and how to remove the piston from the rod.

Well done! The cam will just slide out. Be aware of the lobes' peaks: you can gouge a bearing as they pass thru.

Piston wrist pins: the 4x4 block tool I have works fine.
 
U gotta pic a dat?
 
Can't FIND the bloody thing! All I did was cut a "U" shape cross-wise (of approximate piston radius) in the 4x4 to cradle the piston, drilled a thru-hole a bit larger than the pin. I do have a brass drift made to fit the pins. It's more 'civilised' to use a press on 'em but usually I just whack 'em out.

After seein' the tool you made, I'd be ashamed to post a photo of what I've cobbed together for the task. /bcforum/images/%%GRAEMLIN_URL%%/jester.gif
 
Brains first to think of the tool and then commence building. I just happen to have a water jet. Your head is in the right spot. If I did not have the WJ you'd see a hacked up mess but it would work. I'll have to make a piston support to get the wrist pin out. Other than press fit is there anything holding it in place? A circlip of sorts?
 
Circlips in a recessed land at each end. They're hardened 'wire' and a challenge to remove. I use a straight pick (small Snap-On "awl" looking thing) or a small screwdriver to dislodge them. Others may have a more elegant method.
 
I can't figure this out unless these are different than others.

Those look like press fit wrist pins to me. I don't think they have a circlip, but Doc may know better.

Soak them in PB Blaster and then hammer them out with a brass punch.
 
With the pistons being aluminum, I guess they should be well supported.
 
Scotty is right. Those don't seem to have clips. Brass drift time. They're a press fit to the rods.
 
That's a very cool tool. How do you get the bearing cap back in? clamp the tool to the block?

Thanks
