thats the conundrum!
all it takes is the correct torque.
part of me says f'it ... bolts..
the other half agrees with you.

Yeah is there any chance that the girdle would hold things slightly different thus showing a slightly different plastigage reading? Maybe.

I would use bolts. My thought is bolted up cold not spinning 3600 rpm it won't matter. I'm definitely no expert though.

Plastiguage??? Dude you are a machinist..... Plastigauge???


LOL

yes plastigauge!

main & rod journals checked, and dimensionaly ok, rods checked and good to go.
bearings are .010/.010 under.

after you measure all you can measure how do you check your work?
plastigauge does the trick!
easy and effective.
always "measure twice and cut once"

there are tolerances in bearings too, they are never perfect.
ive never mic'd new bearings...

if the plastigauge calls it good, you know youre golden.
better finding out now than while youre running it!!!

Just yanking your chain. I've used it too but there are those that frown upon it. It's like most other tools. It has its uses and if used properly, it works pretty well.

talking with Al today,
he claims that you only need to tighten the 2 inner bolts to achieve the correct bearing clearances.

think im gonna plastigauge it 3 times, to see if infact it does make a difference


i will post results for the variables below.


95 ft lbs w/ 2 bolts

95 ft lbs w/ 4 bolts

95 ft lbs w/ studs and girdle

Now now...I said you should be able to get satisfacory results with two bolts...hell go step further...do on main inner two one outter two.

All uou are dojng is affirming what you know...bottom line perfect world...studs girdle correct sequence....I await uour results.

Honestly best method...put bearings in block and caps and torqe em in place...no crqnk measure each with either internal mic or snap guage in cross pattern.

Then do platiguage with crank in...

Same w rods...bearings only...then install and plastiguage.

Crap...looks like someone needs buy some mics...crap

Plastic gauge tells you what the entire bearing clearance is. Use it. As far as torquing down a stud or a bolt or the girdle its your call. I personally see no difference happening. As far as being an expert.. Not me. I recall years ago experts built the Titanic and an amateur carpenter built the Ark. I hope I'm never an expert.;:angel::D:rolleyes:

the text man has written lead you to believe that an armature carpenter built a ship to house 2 of every animal this planet had to offer.
i myself believe that he just rounded up the animals, and the "gods" aka extra terrestrials, took their DNA, and went back home..lol

believe what you want to believe! its a free country! (or supposed to be)

FYI, Thor is the missing link, that monkey ****** somofab.....

Bolts will be fine for taking measurements. You will get more change in the dynamics of a running engine to worry about bolt vs stud for plastigauge measurements.
