Splitting Case with seized crank?

That's what I did! Rightly or wrongly, but it's done a few 1000 miles since the rebuild....

 

I think this direction shows the least damage (if damage there is) because it's at 90 degs to where the forces are applied.

 

Can you get in with a vernier through a cylinder hole and read it?.... I'll have go tomorrow!...

But its looking like std/std bearings and hope the plastiguage spreads enough.. My other case measures almost exactly the same just cleaner... but with an oil pick up repair to do

 

What's written on the back of the centre bearing shells?

 

Tell you tomorrow

 

All will be revealed

 

021.105.531 E from the case I'm using

Same for the one from the crank too
Except the crank one is in much better condition. .

Cam 102.101.521

 

Std bearings

 

Doesn't mean they still be standard now, of course

What state are your crank journals in @Deefer66 ?

 

It was more of a thumbs up to the fact that it hasn't been apart before

Measuring things correctly is down to @Deefer66 and his measuring stick

 

I know . Just prompting deefer to do the scraping fingernail test.

 

Crank journals all smooth..and std too
Other case with the broken oil pick up bolt holder has good looking bearings.. Will get new anyway just in case..

Anyway after a day of brushing with paraffin. . Dogs seeing rabbits all over...






Second round of cleaning tomorrow then off we go.. tinted Web shopping. . Now.. any links to oil gallery work.?

 

To get the plugs out.
Drill and tap 5/6mm
find suitable socket it'll pull into
Threaded bar, washer, nut.
Tighten nut.

 

That'll save buying a sliding hammer.. Ta...do I do em all?

 

I have an engine builder for that. - all those taps and sourcing the plugs...

 

They should all come out with a 6mm tap. I replace them with BSP taper plugs. The crank and rods I would sand blast and then polish the journals.

 

Ta .. The crank from the other case is a lot better just a clean and polish should do it.. steel plugs ok or aluminium? 3/8 seems to be mentioned a lot elsewhere...

 

I use plated brass ones, 3/8 does most of them. I use 8 and 10mm grub screws on the smaller ones all with Loctite. You will not have to do the ones on the oil cooler mount as you can clean the galleries with brushes. You should not find any "white flakes" as the case is alloy.

 

Sounds much simpler than sourcing all those npt plugs and plug taps that I see in any of the Google searches... looks like a trip down to Plumb Centre should cover it

 

Although the blue anodized ones do look pretty...
