Ok guys here it is... My problem...

Im replacing my rod bearings and i notice that the new bearings dont have a hole in them. I think its an oil orfice or something. My original rod bearings have a hole in them. Why dont the new ones?...

Heres the part number of the new bearings: 13214-P13-014


Picture of oil bearing



What do i do?? please help... i might be screwed cuz i dont if ill be able to return them. I might get lucky though cuz i work at honda.

Does anyone have the part number of the bearing with the hole in them. I need a Set of Green. Please help me.

 

The hole is for a piston spray orifice.Do you rods have a matching hole in them? Aftermarket rods omit these holes as do some stock rods.This sprays oil on the thrust side of the cylinder walls.I would prefer no hole anyway.

 

so basically having no hole is better because it lubricates the "thrust" side of the cylinder walls therefore allowing for less wear on the pistons and cylinder walls??

 

someone please elaborate. im about to replace my bearings as well. ive got the H22A crank w/ 50mm mains and its got the oil orfice on the rod journal but not on the bearing?

how much was the OEM bearing set BTW? i was thinking of just using ACL but if the price difference isnt too much id like to stay OEM.

 

h22 and h23 rod bearings are different. the h23 rod bearings have the holes in them to line up w/ the galley in the rods and this sends oil to the cylinder wall and piston. the h22 bearings dont have the hole, but the h22 does have oil jets in the block. hope this helps

 

if your stock h22 bearings have holes in them and the rods dont its ok, the factory could have used h23 bearings if they didnt have the h22 bearings readily available as the holes in the h23 bearings will nut hurt anything w/ the h22 rods.

To answer your question. YEs the rods have the matching hole.

WOw...im glad i brought this up. Ok... my H22 rods HAVE the piston spray orfice and so did the BEarings that the engine originally came with.

As your can see in the orginal post their is no hole in the new bearings that i bought. Should i worry about it?? Should i be looking for OEM bearings with the hole or will it not make any difference??

Let me know guys. Thanks!

 

are you sure you dont have an h23 rotating assembly? the part # on the new bearings you showed are for h22. what stamp do the rods have on them?

 

If the rods have a oil orifice as well, def get bearings have the hole. I know Honda changed the rods somewhere in the middle of the life of the H22, which might be the reason these bearings don't have the hole. Early production H22s had thicker rods (and quite possibly an oil orifice as your rod demonstrates).

Get the right bearings to match your rods.

its good to get as much oil to the cylinder walls as possible, but just because the rods have an oil galley doesnt mean you have to use it.

if you want the bearings w/ the hole, you will have to use h23 bearings. what year h22 is this??

 

Wait, these are the bigends of the rods, at least one bearing should have a hole to be fed oil from the crank. If the rods have galley's, then both the upper and lower bearing should have holes.

 

This thread shows what I was talking about with the two different rods Honda produced:

what end of the rod did you think a bearing was going in?? the bearings face the journals on the crank and neither half of the bearing needs a hole for oil to reach them.

Yes, I realized that post was silly after, posting it.

the oil coms from the crank so it doesn't need a hole

does you engine have oil sprayers?
if so then i would use them.
my bearings didn't come with holes but i am using the oil sprayers so it doesnt matter

 

ill take pictures as soon as i can of the rods that i got to show you.... Come back soon Guys!

 

all i know is i dont have oil orifices on my rods or their bearings H22A1

 

Here are the picures guys.... Heres the proof that the JDM h22 has rods with oil orfices. SO what you guys think?? Do you think i can use them?? Also the JDM h22 has the oil Squirter thing too... So...what im thinking is, it doesnt rely on the orfices in the rods to oil up Cylinder Walls. Anyone have any expreience with this??

 

BUMP

 

i would have liked to see the side of the rod and what its stamped. what year h22 is this? like i said, the h23 bearings are the only ones i have seen w/ holes in them so if you wnt to use the oil galleys you will probably need to get h23 bearings unless you can find the correct bearings for that year h22....assuming it is infact an h22 rotating assembly (crank/rods).

Interesting, thanks for posting the pictures. I've seen plenty of H22's and other engines that don't have those holes in the rods, so I think you would be fine to use the bearings as is. If you want to use the oil ports, here is what I would do:

Pull one of the rods out, install the bearings in the rod and tighten the rod caps enough that the bearings won't move. Find a good sharp drill that matches the diameter of the oil port in the rod, and drill down through the port and into the bearing. Use light pressure so the bearing doesn't deform from the force of the drill. Take apart the rod and clean out all the metal chips and carefully deburr and chamfer the new hole in the bearing half. Repeat for the other 3 bearings, reinstall the rod in the block and install the bearings with the holes lined up with the oil ports.

H23 bearings have holes, but I don't know that they line up with your rods. They probably will. If you don't mind buying more bearings and waiting, that might be something to try.

Good luck.

 

i was looking at another post about bearings and came across this site. i would verify that they actually have holes, but from what i saw on the site, when they did show pictures they were for the actual item. even though it says right below it, picture may not be actual item.

or he could just call up the local honda dealership in japan and order some bearings for a 91 h22a, if thats what it is. oh wait, do you speak japanese??

 

In this picture you can see that some h22 rods had the hole and some didn't

I see the hoel that your referring to. Your pic is showing a hole on the cap not the rod side of it. My pics are showing holes in the rod side, FYI. Thansk for your referance.

SO...i see theres alot of good info. So what im gonna do is find out the inside diameter size of the H23 and the H22. If their the "same" size i might just get the H23 rod bearings. If not then im just gonna use the h22 bearings. I hope you guys understoodf that the engine is not USDM so its having some difference. Also the motor is stamped with a date of 1993. Also....I trully dont think its a possiblity that the motor has h23 rotating assemably. It seems unlikely only cuz i bought the motor from an Engine importer.

Thanks Guys.

If anyone else has any info let US all know.
