Engine bearings, yay!!!!

plasti-gauge.. you need to bolt in your crank and plastigauge to find out what bearings you need, and you can do the same with the rod journals. PLASTI-GAUGE!!!!!!!!!!

And it will only tell you if you're at/between .0015" and .002"

It will not tell you you're at exactly .0016" for example.

It should be used for confirmation that you are in the appropriate range you are shooting for (ie. .001" - .0015" or .0015" -.002")

And it will only tell you if you're at/between .0015" and .002"

This is exactly why I haven't used plastiguage. It's not accurate.

I'm aiming for .017", on the rods.

I'm also trying to figure out which bearings it has on there. The way I measured, the bearings are too thick to even be greens.

Just peace of mind I guess. I don't NEED to do this, but after seeing a to-be customer's car die because all he did was slap on the bearings his block called for, I'd rather measure everything precisely.

This is a picture of my JDM H22A block.


If you cannot read it; it says: 22222.

[d112crzy]

Interesting, what's on your crank?

[The G-Man]

Not sure. I have not taken the crank out yet. That was a picture I took right after I took the dented oil pan off.

[wed3k]

to measure the bearing, id use a micrometer with a .100" ball at the end.

[westsideaccord]

say I dont have a micrometer.
I do have the stats on my new crower rods, 2.0080 (big end diameter)
and I have the crank letters all C-C-C-C for the con rods
so where can I find a chart to tell me what diameter C is?
Cause (2.0080-crank thickness of C{which is?})-oil clearance of 0.0015= bearing size or colour?????

[d112crzy]

Go buy a mic set, they're not expensive.

But, hoping your journals are not excessively worn or scarred and are close to stock specs, they should be, depending on year;

Rod Journals

1990-1992
1.7710 to 1.7717 inches

1993 
1.88888 to 1.8898 inches

Main Journals

1990-1992
Journal 1 and 2 --- 1.9676 to 1.9685 inches
Journal 3 --------- 1.9674 to 1.9683 inches
Journal 4 and 5 --- 1.9665 to 1.9688 inches

1993
Journal 1 and 2 --- 1.9676 to 1.9685 inches
Journal 3 --------- 1.9674 to 1.9683 inches
Journal 4 --------- 1.9679 to 1.9688 inches
Journal 5 --------- 1.9680 to 1.9690 inches

[wed3k]

damn rod journals are different sizes.

Plasti-gauge is simply used for letting you know if you're in the range you should be. That is all I used it for, confirmation. The rest is measurements and calculations to be precise.

[westsideaccord]

So I bought three mic's 0-1" 1-2" 2-3"
I mic'd my rod journals as:
1) 1.8893
2) 1.8892
3) 1.8893
4) 1.8893
I mic'd my main journals as:
1) 1.9685
2) 1.9681
3) 1.9680
4) 1.9682
5) 1.9686
And my conclusion is pinks for the rods.
But as for my mains, I have no way to measure the ID of the bearing tunnel, accurate enough. Would in that case just use the blocks stamping; 3-2-3-3-4
and cross reference that to??? A)my cranks stamping, or B) to my measurements above, which will relate to what size?
This is a little brain racking for me lol!

[wed3k]

i hate to answer questions related to money...

1. bring it to a machine shop and have them check the main bore housings.

2. https://www.wescotools.com/p-1708-cy...y-central.aspx

set your mic to the minimum or maximum bore housing spec, set your dial bore guage and then indicate.

plus, this tool is also good for cylinder bores (what it was actually meant for)

[westsideaccord]

First off, Thank you for your response.
And just so Im clear, what your saying is that I have to take it to a machine shop? Or buy a super pricey dial bore gauge? Huh, then why do they even stamp those numbers on the block? I mean you are exactly right I cant afford to pay a machine shop to measure the crank journal bore, and cant afford to buy a cyl dial bore gauge thatll only be used like maybe a few times in my lifetime! I guess Im fudged.

Still no one has answered my question, what is the measurement for bearing tunnel in reference to the stamping on the block, or has anyone found a referance chart for f22a, theres gotta be some way to tell. Like what the 1-2-3-4-5 etc is in reference to bore size am I right?

I do want to get this right thats why I ask so many, be it annoying, questions! I am very budgeted, spent all my money on rods and pistons so I always do the work myself and with having mechanics for dad and brother, youd think I could get through this.

[wed3k]

except those stamps dont tell you the housing bore size whatsoever. those were there when it was last built so the specs could have changed.

that isnt a super pricy bore guage either, one of the cheapest i have found. there was somethong on honda-tech, this guy made a bore guage out of a mic or something. ill see if i can bring it up.

[starchland]

im just wondering why someone would think its ok to use the bearing size stamped on an engine if your rebuilding it and it has 200k for example, wouldnt you measure the tolerances?
