Hey guys I'm currently building an H23a1 to run an h22a4 head. Already have the motor assembled for the most part but I'm hitting a road bump as i try to finish putting the timing back together. I've scoured threads and i have digital copy of the factory service manual already that I've also thoroughly searched however I'm still stumped.

The problem I'm having is that I'm trying to determine exactly which h22 timing components need to be swapped onto the h23. I already changed the inner crank timing gear, swapped the manual belt tensioner for the automatic one, and changed the water pump for h22 parts. The problem I'm having is that the timing belt isn't going back on. With no tension set on the belt via the auto tensioner, I can't seem to get the timing belt on, it seems to be too short. I work part time at a local part store so i know that it isn't the wrong belt.

So my question is this, has anyone else here put a 5th gen head on an h23 4th gen? If so what components did you use? And has anyone else had this problem?

 

Sounds like you are on the right track, you need H22 crank timing gear, H22 cam gears, H22 water pump. I would reccomend that you stick with the H23 manual tensioner since its more reliable than the autotensioner.

If you are using the autotensioner is the piston compressed? When you buy them new they come with a clamp/tool that holds the piston compressed until you install it. if you dont have that then you will need to take the small screw out on the bottom of the tensioner and unscrew the tensioner and find a way to hold it while you put that little bolt back on and get it assembled onto the motor. Don't forget to put a few drops of oil in there too.

 

The H22 belt is generally a very tight fit, especially if you swap to the manual tensioner. Just keep working on it, and it should go on. As mentioned, if your tensioner is not compressed all the way, it will not go on.

 

ok guys i got the timing belt on, now im having trouble with the balance shaft belt assembly. I have all the pieces, put them together just like the service manual says. The problem now is that there is absolutely no tension on the balance shaft tensioner. I thought that it was the tensioner spring, so i got a new one from honda, no cigar. What happens is that the tensioner assembly for the balance shaft belt just kind dangles here. is there a tension setting procedure that i'm not aware of?

 

Nothing really magical. The Helm's says to leave the adjusting bolt loose on the belt tensioner, turn the crank a few times and then tighten the adjusting bolt. It apparently doesn't need a huge amount of tension on the belt.
