Rod and Main Bearing Color Codes, Plastigauge color.
I just recently started my first ever motor rebuild on my d16z6. I started looking in my helms manual today and it mentions color codes labled inside the motor, and to use those codes to choose the correct bearings. I haven't gotten my motor apart yet, so i cant read the codes just yet, but i have already ordered a set of ACL STD rod and main bearings off of ebay. How will i know if these bearings will work? What color plastigauge should i use to check the clearances? I hope i didnt screw up ordering the wrong bearings and waste my money
thanks for your help HT

i just read that ACL bearings are more of a "one size fits all" and the clearances are going to be "good enough"
if thats true then ok, but still need to know what color plastigauge to use.
for some reason i have green in my mind , but want to be sure

for my b18b that im rebuilding, i took a crank from one block and put it in another block, and the ACL bearings that i had were not the right spec size. So now im trying to pick this motor up from my buddy today so i can mic the size of the bearings and order the correct ones for the rods and mains.
heres what im useing to help me out (first time doing this) http://www.evans-tuning.com/tech1.html
same idea just use your correct specs for everything.

Grab a service manual and see what the spec is supposed to be and then go to the auto store and see what plastigauge falls in that spec

The acl std bearings around about a 'green' color when compared to stock and will give you an alright fit, unless your crank is way out of spec.
The only way youre going to know if theyre going to work, is to assemble the bottom end, one journal at a time, w/ plastigauge and then check the measurements of each section.
If its within spec, youre good to go.
If its out of spec, you need to order a different bearing from honda, based on your readings.
(so you'll need to open up your helms and read the specs for each color, do some math, blah blah)
When I did mine the first time, the color coding was beyond confusing for me, so acl was the way to go.

Plastigage is a waxy clearancing tool. Its like a wax thread. Comes in green and red.
Looks like this:

ACL race are looser bearings that have a different type of material on the surface than the std bearings.
They are not better than std, in any way.
If you are building any sort of street car, use the std bearings.

Small world, I'll be soon rebuilding my Z6 block. I just picked up STD ACLs on Ebay and some Plastigage from Advanced Auto last weekend. (AutoZone emplyoyees were like, what's Plastigage? LOL) Before anything, micropolish the journals on your crank. Then using Plastigage, lay down a small strip in each journal (one at a time now) and torque to factory specs. (You'll need the bearings in/on at this time) use the provided "chart" to guage what oil clearences you have. The Honda allowable max is .002 I believe, but double check your Helms!
Good luck!
Good luck!
okay thanks. if im installing new pistons n rods do i need to remove the crank? if not, should i do it anyway so i can replace the bearings. or will i just run into more problems. im planning on ordering ACL std. n i need to know if i should get the kit or just the rod bearings.
