Oil pressure issue / motor rebuild

<< < (22/44) > >>

MrDavo:
The bores are like brand new, and you can make the rings pop out, but the bottom of the rods (where the big end bolts are) are wider than the liners.

Cut it so that it fits where the crank would be but is pressing against the liners of the barrels. The wood would need to be thick enough that the lower casing won't quite fit, then bolt the casings together, the pressure from the bolts should pop the barrels off, you only need it to break the seal and they'll come off anyway. OR use the same piece of wood as a drift to protect the liner and hit it with a big hammer. Maybe cut a circle of wood just bigger than the liner so as to spread the blow around it.

That may push the liners out Oddjob
If the liners are removed, then the con rods will go through the liner holes.

AshimotoK0:
May have some F1 or K7 cases but not a lot of use to you. Neither are the ones unstamped that Freddie has as I think they are for a later engine (ask Trigger). Your best bet may be DK and they are not a million miles from you.

MrDavo:
Ive not completely given up on these cases, that guy did get his aircraft engine re line bored (and AFAIK he didn't fall out of the sky later), I suppose the question is how accurately can it be done, there is a good engineer round here who polished a couple of thou off the crank journal of my Sportster to fit a new crank to my existing cases' roller main bearing. If the cases were torqued together to spec it would be interesting to measure up at least, if its locking up then the journals cant be oversize. I don't know yet whether the shells are still Ok, they were last time I saw them. If I'm really lucky I'll get a set of AAAAA cases!

The proof of the pudding will be once its all stripped down again and when/if I get those barrels off. In the meantime keep an eye out for K1 cases, though.

MrDavo:
Well that's one problem solved.

Rather than pussyfooting around tapping with a rubber mallet and a 'mustn't leave a mark' attitude, take a dose of contempt, a decent size hammer and a big screwdriver to use as a drift, and behold, I've broken the base gasket seal, and ironically, not left a mark.

I've just popped in for the manual as the camchain tensioner is in the way of pulling the barrels off - it's going to make the stripdown a lot easier without all the keyhole surgery approach.
