im trying to rebuild my motor for the first time but now im stuck. i have a d16z6 motor in my 89 hatch. i took apart the bottom end and 3 of my rods bearings are green and one has no color. also 3 of my main bearings have the same number on the back but one doesnt .

1.what the hell does that mean.

2. what size are green and how can i tell what the other sizes are.

3. i want to replace all the bearings with acl race bearings but how do i know which ones to buy. they dont go by color.

someone please help me out. im not the worst person when it comes to this stuff so i should catch onn pretty quick.

go to the autopart store, pick up some plastigauge, use it, it will tell you whats the correct size replacement bearigns to get.
oh and go with OEM honda

:|

use the numbers and letters on the block, crank and rods and grab a service manual to find the correct color bearings. I suggest OEM, but aftermarkets bearing have been used with success

ACL bearings are sold as sets in the "Green" range. So all of the bearings would be green in an ACL box. This is what ive heard and pretty much backed up with plastigauge readings.

the amount of clearence i have will tell me if my bearings are still within spec right? but if im buying new bearings i will also have to spec thoes also right. so i think i might haVE IT NOW. i should check my old rod bearings first to make sure my crank is within spec. then i can order my green(sized) rod bearings because if my old ones are within spec then i can get new ones the same size. but i just dont know what clearence number im looking for. and is the plastigauge i bought the right size for the clearence im looking for? .001 to .003in (,025 to ,076mm

what size would the green ones be. the store doesnt know what i mean by green.
Auto parts stores don't have any of that information. Most sell all "greens" without even knowing it. Color sizing your bearings can only be done with OEM Honda Bearings from the dealer.

i think i have to go back to the parts store because clearance i need is between .0008-.0015 in. and the plastigauge i bought measures between .001-.003.

use the green plastigauge. stay around .0015-.002" and all will be well.

or just, remove the bearings, lay a strip of plastigauge down, keep the bearings out, tourqe down the rod caps, then remove them and mesure the plasitgauge
yeah let us know how that works for you.




find the colors for your old bearings using the codes on the block and a repair book and go from there. if you have black or reds in there, aftermarket bearings arent going to do shit for you.

why are you so set on using acl race bearings? do you know anything about them other than they say "race" on the box?
