Hi Nils,
not quite sure what you are doing there,
but it may help to know if you are measuring with metric or imperial tools.
To get any sort of accuracy you must use a micrometer.
Digital verniers will not be close enough,
other than seeing if the bearings are the correct ones for the crank ,and case machine work.
If the line bore is 1.25mm,
then 1.5mm backed bearings are too large.
One thou is only 0.0254mm so 0.25mm is too much crush.
Once you have determined the correct bearings,
and made sure there is no dirt, corrosion or dents on the bearings (and case tunnel),
the next step will be to mount the bearings-only in the case
and see how much clearance you have on the crank shaft journals.
If you are confident of the case tunnel being straight,
then any tightness wil reveal its self in a lack of correct oil clearance,
or the radius of the crank machining, ight be binding on the corner of one or more bearings.
Check also that the crank is straight,
by laying it in one half of the case with a bearing shell on the FW and one on the gear main,
and running a dial indicator on the centre main journal,
and then on the nose main as well (pulley end).
I like to run a fresh stanley knife blade over the bearing tunnels on the case
to pick up high spots that are common around the dowel holes.

yeah i was just using old measuring tools of questionable condition, for some reason half of my last reply was deleted. i actully went out and bought
a new micrometer and dial bore
The problem was that they messed up the grind on the front two bearings of the crankshaft, even left them out and torqued it up and.. . . . .
.surprise! it spins! the only reason i didn't check the crank was it was covered in that red gunk, (you know what they say about assumtion)
am trying to work in metric here but, everybody keeps refering me the imp measurements, so i have this horrible half half thing goin on.
BUT, found the problem, wasn't me (turns out, am not as dumb as i look)
so back to it next week
will check to straightness when i get it back, suppose to have done that too, but seeing as how they messed up the grind will be more concisous

Good to see you sorted out the problem.
That red preservative is common toonly a couple of businesses I know,
so yes, check their work!!
Make sure you clean all that red gunk off the crank before assembly.
Cleanliness is next to godliness.
The parts can never be too clean.
I work in both metric and imperial,
but try too keep within one unit of measurement on each job.

finally got my crank back (again) and had my case checked again after being told that the bore maybe too small. which the guy said it wasn't, but
strangly the surfaces have been touched up. . . . . . . . . . have now put in the crank and bearings, torqued them down and, HOORAY! perfect smooth,
easy turn
now the downers. .. . .. . . the case guy wanted the bearings in the case and the crank to check against, long story short only came back with 4 dowel
pins
so won't have that till the weekend. bum

OK! got all the parts and i know for sure it all fits now! How long ago was it that i started this?
lifters in, (yes i know the lifters are numbered wrong, i picked that up staight after i took these photos)
dizzy and drive
bearings seated and MARKED 
crank assembled
crank in
cam in on the marks (torqued the other half at this piont to check fee spin again - IS GOOD!)
I know that the cam plug, other half lifters and the surge plate are still to go in, but anything else you lot can pick up before i close up tomorrow?

Diamo was right! the dizzy wasn't far enough down - nice pick up
And Matt you're right too i had't cleaned the surfaces yet. thought i had some metho, turns out i didn't. picked some up on the way home
(can't put anything past you guys!) - THANKS
and Matt, is it technically a peticure? probably due to my 2 left feet standing on them on the weekend (are my girls feet, was taking the photo as she came down and ask if i was coming up for dinner)
- sorry again about not catching up with you at dubs/ totally spaced
Aside from those small indiscretions it went together today no drama (might still put a bit of permatex around the the main bolts now that i think of
it)
Tomorrow - rings (maybe get the piston and barrels on too, see when i finish work)

Finally got some time to get somethings done on the engine this afternoon, (been on the gold coast, from friday)
The rings checked out ok, definatly be the last time that the pistons/barrels are used. Not sure what it will do to the longevity of the motor,
because the pistons were right on the end of the wear limit my ring gaps all came up between 0.45-0.5 (specifications say .25-.45 with .9 as a
limit,
still better than my old rings! think this is why it blew oil?
didn't have too much time but have the barrels on now and new deflector tins (old ones rusted and fell off a while back)
and for those who worry about the cleanliness of my work space, here its is

got locked out of the house today. BUT, gave me a chance to work on the engine in the garage!
Checking the deck hieght and TDC seemed a little over the top for and engine that is pretty much stock. Besides it is the same parts, in the same
places as last time and took a beating! So once it all went around and the arrows where all pionting the right direction, glued and fastened then
down.
Stretched the tubes, new seals and put the heads on. easy. checked the push rods for straightness and put them back where they came from.
Then looked at the rockers (still the stockers) are quite warn on the feet and even the shims could use a bit use a bit of attention. So a few
questions, can i get decent quality feet and shims? - am not game enough to put empi or scat parts in my engine
Or, am i better off spending some coin on some after market rockers to get rid of those silly clips?
Any suggestions? (keeping in mind this is for a baja, torque over HP)

have the rocker gear sorted now and am just waiting for it to show up, matt hooked me up with some swivel feet adjusters and a rocker shaft kit to get
rid of those clips.
In the mean time have been putting on a few of the other bits like the oil cooler and new oil pump. Went for a 26mm pump this time arround because
of the starvation that i got at continued high revs (really sucks when you are in a really boggy situation and you have to stop and get bogged so that
your engine doesn't blow up!) anybody want a 30mm?
Did a good measure up and look over the rocker gear that i have, This is what worn out push rods and adjusters look like?

Actually had no idea push rods could wear out, or more to the piont beak down. so i thought it was interesting
have this ever growing list of little things that i need -
- sand sealed pulley kit, nobody seems to know if the kit that you can buy are any good
- 6 of those thick washers that hold the heads down
- woodruff key for the front of the crank, crank came back without it after the second grind (knew i should have popped it out myself )
hey matt, any news on that rocker gear?

Jeez, its been awhile. . . . . . . . .been working on the baja that this thing goes in. The engine has taken a bit of a back seat seeing as how
without a car to put it in is no real piont having an engine.
Got those silly washers i've been chasing so the heads are finally bolted down, and now that i have them bolted down am concidering taking them
apart again. Have been looking at the match, or rather the mismatch of the porting of the head to manifold. Is it really worth grinding the ports with
such a mild engine? what kind of gains can i expect? and it is as easy as just taking the valves out and getting in there with a bur and flapper on a
die grinder?
Got my rocker gear, and have had a bit of a fiddle trying to work out the geometery and get my head around the whole concept. With the swivel feet,
being alot bigger i have been told that i have to grind the bottoms of the rocker arms,
This little step here right?
Lastly, in the solid rocker shaft kit there are 2 washers with cutouts in them, thoughts? i got nothing

The notch on the shim goes where there is interference with the rocker stand.
Porting?.....mmmm any gain is worth it, but now it's all together I probably would leave it alone this time.

cut down the rockers this weekend so it all fits, i would like to have made it all fit without the spacers on the studs. I would think that with
standard rockers and valves the whole thing would not have to move. but i have not measured the mid point and angles yet so time will tell. I can't
cut anymore off the arms, because i am already worried about the oiling hole in the swivel adjuster not lining up. I cut off a total of 2.5mm of each,
as you can see was barely enough on some.
and yes steve, they don't bolt straight up. The heads of the adjusters are HUGE that space needs to come from somewhere

make them right in the first place??
or am i missing something here?
