Alright,
I am using ACL main bearings. I went to torque my main bolts on my b16. I started from the outsides (1,5) and then worked my way in. After tightening the # 1 and 5 main's, I tried to spinn my crank and it wouldn't move. I thought that it was because I didn't tighten the others yet, so I went ahead and did that. Crank still didn't spin. I am using 56 lb ft. on main #'s 1 and 5, and 49 lb ft. on 2,3,4. Also, as soon as I loosen up main # 5, the crank will begin to spin again freely. Anyone know what's up with it?

First, are you using the right pattern to torquen them down?

Next, did you plastigage them like you are supposed to do?

haha funny me and my buddy was talkin about this issue with a Big Block he was building. He had (just and estiamte) .001 of clearence in between. you have to grind it down, but i wouldn't do that. get honda bearings.

You might need to get an align bore.

m R g S r

No I didn't plastigauge them yet. Do I need all new honda bearings, or can I just order one? I'm not lookin to cheap out on this, I just don't want to spend another $100 or so if I don't need to.

ahobbs

What colors where on the main caps before you took them off.

earl

Pull #5 bearing from the block and make sure there is no dirt or knicks in the metal of the block that might not let the bearing seat properly. It does not take much to not let the bearing seat properly. If that is ok:
You need to plastigage #5 before you make any decision.
I don't think it is a bearing clearance issue as much as an improper install.

m R g S r

Alright, thanks guys, I'll check it out and I'll let you know. Where can I get the plastigauges, local auto store?

m R g S r

The block that I bought from RenoRacing, and I don't see any colors on the mains caps. Also, the caps didn't come with bearings in them.

RenoRacing

the block had ACL's in it, I'm not sure what the crank donor had color wise, i think there were a few loose bearings in the mains still when I sent them too ya. Plastiguage is dirt cheap and can be had at most auto parts places, you'll want the green plastigauge.

m R g S r

I think one or two had bearings, but I got rid of em. Alright, I'll check it out tomorrow, b/c nothing is open around here @ midnight.

Its hard to use ACLs when the crank didn't orignally come from the block...

that's why i like honda

m R g S r

So how do I go about ordering Honda bearings if I don't know what color they originally were?

Suprdave

Match the new crank with the block...

earl

I understand what you are saying but the difference in Honda color bearings is not enough to un freeze a frozen crank. Adding an additional .0004" will not go from frozen to perfect clearance...Something else is wrong. Either the block needs an align bore, there is junk under the bearing, the torque is improper, the crush is goofey, the crank main is bad, the crank is bent...on and on

RyanEJ8

I agree with earl. The ACL clearances would not be so tight that they would freeze the crank up. You are installing them wrong.

m R g S r

I don't get how I am installing the bearings wrong. I just re-cleaned everything and used plastigauge on all the bearings. This is the way I installed the mains:
Forom the oil pump side- 1&gt; 2&gt; 3&gt; 4&gt; 5&gt; Flywheel Side. All of the bearings were in spec (.0015" and a tiny bit smaller) except the last one, it was slightly tighter, about .001" clearance.

Alright, so if the bearings aren't the problem, what should I do, purchase a new crank or get an align bore?

It probably needs an align bore. Have a machine shop check it. Did you use the same main caps/girdle that came with the rest block?

Jared

did you have this block sleeved?

The pounds you are quoting are for the b18c engine with a girdle. I THINK the B16 is different. Also be sure you are lubing the bolts with regular oil and not moly lube.
Anyone know the b16 main torque specs off hand?

also never seen a honda block torque from inside out alway's from center out. removing crank is from outer in.

m R g S r

What are the torque specs for a b16?

m R g S r

Alright, I did a little search and came up with b16 torque specs.Someone stated that it was a two step procedure. Does 18 lb ft (first) then 58 lb ft sound correct?

Jeff33S

yeah I thought all hondas were the same tighten center out and loosen out -&gt;in
