Superseded crankshaft bearings
« on: March 26, 2010, 10:14:41 AM »
I received an order today containing some new crank bearings.  I ordered 6 x 13318-422-003.  What I received was 1 x 13318-422-003 and 5 x 13318-425-003 which is the superseded part number for the Yellow crankshaft bearing insert.  The parts are dimensionally the same but have a different color and may be different materials.  Anyone see a problem with running these together or should I go back and get one more of the 13318-425-003 bearings?

Sorry, cannot post pics at the moment but I'll post some when I get home.

cheers

Although they should be perfectly compatible, I'd get that one final one ordered for peace of mind... otherwise I'd be wondering about it every time the motor missed a beat.

Here's the pics,

Shell on the left is the 13318-425-003.

Shell on the right is 13318-422-003.


13318-425-003 is the "newer" number.

As you can see, the newer ones are uniformly satin overall.  The older one has a different finish in the oil channel then elsewhere, and is overall a different color than the newer one.

I can't see a problem with that.
It's nice to have everything uniform for peace of mind and it isn't uncommon for parts and part numbers to be superseded over and over in the automotive industry.
They are all genuine Honda parts and should be fine.

If you decide to use the odd bearing, put it in cylinder#2. They wear the least, in my experience.  ;)

The other ones should actually be aided by the extra oil reserve in those little holes. This seems to be good news for all of us: it means some other bike engine uses the same bearings as our SOHC4 bikes, but with oil holes in a different position. Cool!  8)
See SOHC4shop.com for info about the gadgets I make for these bikes.

The demons are repulsed when a man does good. Use that.
Blood is thicker than water, but motor oil is thicker yet...so, don't mess with my SOHC4, or I might have to hurt you.

Thanks for the input everyone.  The green inserts that I already have are the 425 style so looks like I'll be ordering up one more to replace the 422.

"One of these things is not like the other" just doesn't play well with me :D  Anyone need one yellow 422-style crankshaft bearing shell?  :D

cheers

I'm going to guess and say you got these from BikeBandit, no?

I say that because I just got my shipping notice from them and it looks like they subbed both a con rod and an crank bearing for me. I'll have unmatched pairs for both.

Have you contacted them to ask that they send matching pairs? I'm wondering how their customer service is.

Nope, wasn't Bike Bandit, but another outfit that's popular here on the board.  I actually have no complaints about the vendor and based on past experience, they'd probably take care of me, but I didn't want to wait for the replacement nor pay shipping on a single shell, so I walked into my local honda shop the other day and ordered one up, should be here soon.

If I were you I'd call up BikeBandit and see if the stuff has actually gone out the door yet.  If not, ask them to sub in matched shells.
