Read the rules:

Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)

Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.

These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

The rules for the overall forum can be found here:
Read them. You will be expected to follow them.

    h23a / f22a6 interchangable internal parts ?

    gm folks i ve spent the majority of the morning reading, i have not found the info im looking for so im gonna ask , does anyone out there know if a stock f22a6 crank will match up in a stock h23a1 bottom end ?

    i found what i needed to know in this thread hear ** H/F Series Engine Dimensional Info **

    great info the h23a1 and the f22a have the same crank rods and bearings so im goo to go on my rebuild !


      Sorry I didn't see this earlier but that's great that the search feature yielded results for you. Yes, you're correct that they're the same. The only difference between the rotating assemblies of an H23A1 and any F22A/B (aside from some trivial rod casting differences over the years) is the pistons.

      Two other points:
      Be sure to measure very thoroughly for each individual bearing surface because Honda has different color-coded bearings to achieve appropriate clearances when rebuilding.

      Also, if you have questions on part numbers in the future a good method to use is searching and comparing two part numbers in question. Sometimes that's still not totally conclusive but the pictures help. If it's something you need dimensional information for the RockAuto's catalog is great as well.

      Good luck.

        wow thanks very helpfull website ok another? how to you tell what color the bearings are are they markd some wear on the bearing block or crank side possibly (i hope): ?? ok the honda web site does not seem to have the full engine gasket set wer would you suggest i get a complete set from ? im trying to buy one whole gasket set with seals so i dont have to even consider it haveing any leaks later down the road


          As far as I know there isn't a "kit" available unless some third part vendor has assembled one with Honda parts and is reselling it. The easiest thing would be to start at the headgasket and work your way down noting part numbers as you go. Then go up from the headgasket repeating the process.
