h23 manual belt tensioner conversion problem

so first off, I have done this h23 tensioner conversion on an h22 block before, it was just some time ago.
long story short, I took my car to a shop to get the timing belt changed for sheer lack of time.
I bought the h23 conversion kit off of IRP.com and printed out a diy from preludepower for the shop.
shop calls today and said there is no way to get the belt on, the h23 tensioner pulley is about 1/4" wider radius then the h22 pulley, hence the belt is too short.
the conversation was over the phone, could not get down there to see what was up. I remember when I did this conversion the belt was uber hard to get on, but I did do it, also the engine was out of the car. so, anybody have any other ideas what the problem could be? I don't remember reusing the h22 pulley, I used the h23, also using an h22 belt. is an h23 belt longer or would getting a longer belt solve the issue? or maybe the shop has the pulleys set up wrong? or maybe trying out a KAIZENSPEED timing tensioner?
I hate having other people work on my cars

Re: h23 manual belt tensioner conversion problem

I've done the conversion several times and what I've found to work best is that leaving that 10mm bolt off(the one holding the tensioner pulley in place) and then the belt slips on. Still a little tough, but it'll go on.

are you talking about the bolt that goes through the tensioner or the bolt that holds the spring?

Re: h23 manual belt tensioner conversion problem

I did the H23 manual tensioner conversion on my built H22 and spent a good hour trying to get the belt on. What I did was put the entire belt on both cam gears and zip tie the belt to both cam gears. Then go down to the crank but only put 1/4 of the belt on the gear then with the tensioner loose like Prelude1897 said put 1/4 of the belt on the tensioner then go to the water pump and just keep trying to pull the belt over the water pump gear. It's going to be tight and super hard to get over but it will go on. Once you get the belt on the water pump just push the rest of the belt onto the tensioner and crank gear. Tighten the tensioner bolt and check all your TDC markings after a few crank turns.

God damn it, that is genius.

Re: h23 manual belt tensioner conversion problem

I loosened the cam caps so I cold tilt the cam gears down a little bit. Probably not the best way to do it but after spending 45min trying to get the belt on, it was a good 3min solution. Gotta know how to torque the caps down though so if you don't trust the shop much, maybe don't give them this idea.

There's no point of him buying the KS Tuned manual tensioner when he already has the H23 tensioner. H23 manual tensioner is not hard to install, you just have to know how to route the belt with only 1/4 of the belt on the crank/water pump gear and tensioner and it will go on just fine with some muscle. You do it once and it becomes easy the next time you do it.

I've heard of people loosening their cam caps to install it. But I agree, don't tell the shop to do that. They can easily bend those cam plates if they don't know the torque sequence.

Re: h23 manual belt tensioner conversion problem

I went though my old pictures of my rebuild and I tilted the cam gears, +1 on the zip tie idea. I looked into the kaizenspeed tensioner, but I bit the bullet and bought the oem honda tensioner because I can't afford them to dilly dalley, and 50k miles down the road I'll just swap over the h23 tensioner myself. fingers crossed for the auto tensioner to last that long, in the meantime, no VTEC for me! thanks for the responses guys, I am about to make another "stuck axle" thread haha

Re: h23 manual belt tensioner conversion problem

What do you have done to your valvetrain? It it's stock you'll be fine with the OEM tensioner. If you put stiffer springs that tensioner will fail in no time, even with driving like a grandma.
