Changing bearings

[F22A1forlife]

Im going to have the change the main and rod bearings in my f22a6. I wanted to know if i had to pull the motor to do this on these motors or not. Id like to not have to pull it but if i have to i will. Thanks for any help guys.

Have you consulted an automotive repair manual or equivalent yet for the type of work you anticipate on doing specifically for these cars? That would ultimately be a great place to start and offer a source of reliable reference for the clearances you need.

pull the motor, sweet and simple

i have done this on a bunch of different cars and its always the same story

how are you going to replace the mains with the crank still in it?

Exactly. If you want to change the main bearing, you need to pull the motor out.

Rod bearings can be changed with the engine still in the car. In fact, the Accord service manual specifically includes instructions on how to do this.

the problem with doing rod bearings with the engine still in the car is there are so many variables with the rod journals on the crank and the rods themselves.

in my years i have only seen one instance where this procedure was done successfully and that was on an old Mack diesel engine.

id personally just inspect them because most hondas are built pretty well and don't wipe out rod bearings. but if youre going to take them out, make sure you lay them out in order...and check the color code on the side of the bearing.

I recently did this on my F22 engine. Yes, every rod journal and every connecting rod has a code and I had to match them all before I ordered my bearings. But the instructions in the service manual were detailed and accurate. I just took my time and ordered the proper OEM bearings from Honda for each cylinder, as specified in the service manual. No problem.

It would have been even easier if I was willing to trust the color code on the original bearings, and just ordered the same color bearings. But I'm paranoid enough that I double-checked the color code against the codes on the rod journals and connecting rods.

I agree with you. I checked my rod journal clearances and they were all still within the service spec. The reason I went ahead and put in new rod bearings anyway is that I want to push the engine to higher rpms than it was designed for. I figured new rod bearings would stand up longer to the abuse.

you shouldve went with the acl race bearings.

I just looked them up. They look great. I wish I would have done this. Unfortunately, in all my searching on how to build up the F22 engine I don't recall ever seeing any mention of race bearings, so I didn't know they were available.
