I am in the process of rebuilding my D-16 Y-8 and I have hit a bit of a snag. I had the crank balanced, and micro polished at a local machine shop, and reassembled the motor using ACL bearings. When I was installing the rods I noticed that they have a significant amount of play. Even when they are tightened to the torque specs that came in the instructions they still wiggle.

The rods are made by Eagle, and have had no modifications done to them. I know that Honda used a color system for the bearings, but is there a way to estimate the bearing size by measuring the crank. I am assuming that the machine shop either accidentally turned the crank, or it had been turned by the previous owner.

Any assistance would be greatly appreciated.

The crank is out of a 1995 Civic Ex if that helps any.

 

How close are you to Jacksonville, FL? Don Flores, DonF here, can help you.

I am about 4 hours away from J-ville. I might be in luck, I was reading in another thread that ACL bearings are made in ten under, and twenty under sizes as well. IF this is true, I am good to go. I guess I am spoiled, domestic motors are easier to get the proper bearings for...lol

 

You need to measure the crank.If it was reground then your mains are wrong also.Its rare to have the rods ground only (although it does happen).At least plastic guage the mains and rods.

I am thinking fo getting brown, and black rod and crank bearings and then plastigaguing them to see if they can come close. I don't really have anything sensitive enough to measure the crank with.

 

wich way do the rods wiggle? im assuming your saying you can move them up and down...
if its really the case the crank was turned i would defenetely get a micrometer to measure the crank; they are like $20....or i would get someone qualified to do it.
as sayd, plastigauge to see what you come up with

 

yeah, they move up and down. I am just kinda new to the honda bearing system. As I said, domestics ar so much easier...lol

 

just plasti gagued it ...0015.... good to go..thank God
