HOW TO: H22 Auto Tensioner to H23 Manual Tensioner Conversion

98vtec · 11-30-2005, 12:18 PM

Write-up done by Scott Bryars

This seems to be a hot topic for the H22 owners out there. Here is a step by step "how to" conversion to the more reliable H23 (manual) style of tensioner. The H22a block used, is obviously a "mock-up", so don't be critical of the missing pieces. This conversion can be done in the car, but in this case it was done out of the car for illustration purposes only.

Parts list:

13404-PT0-004 - ADJUSTER COMP., BALANCER BELT
13415-PT0-000 - BRACKET, BALANCER BELT ADJUSTER
14510-PT0-004 - ADJUSTER COMP., TIMING BELT
14516-PT2-000 - SPRING COMP., TIMING BELT ADJUSTER
14521-P14-A00 - PLATE, ADJUSTER
90014-P14-A00 - BOLT, TIMING BELT ADJUSTER BASE
90015-PT0-000 - BOLT, TIMING BELT ADJUSTER SPRING
90016-PT0-000 - BOLT, TIMING BELT ADJUSTER
90140-P14-A00 - WASHER, PLAIN (11MM)

Here is a link for the parts list: http://www.hondaautomotiveparts.com/auto....%282%29
__________________________________________________ __________
This is a frontal and side shot of what the auto tensioner set up looks like with the timing belt cover, balance shaft crank pulley, balance shaft belt, and timing belt out of the way.
All of these thing will need to be removed to do this conversion.

Start by removing the auto tensioner pieces. These following pictures should be fairly self explanitory.

These following pieces will be removed from the h22 in this step and set aside for later use.

With the parts removed this is what it looks like.

This step, we will remove the troublesome auto tensioner.

With the auto tesioner gone, we will remove the rest of the tensioner mechanism. The following pictures should be self explanatory.

Now, with the complete auto tesioner mechanism removed, we are ready to add the manual tensioner parts.

This bolt and washer are what we start with. The factory washer is critical! It has a larger diameter than the block casting. This is a factory Honda part #90140-P14-A00 - WASHER, PLAIN (11MM), but for those of you who are lazy or pinching pennies, the diameter is 40mm and the thickness is 1.5mm If the wrong washer is used, improper alignment can occure as well as limited movement of the timing belt tensioner pulley.

These 2 pieces will be added next.

Add the timing belt tensioner pulley and check to see if it has full movement on its pivot.

Next we will install the balance shaft tensioner pulley. For this install, we will re-use the H22 part. The H23 part has a larger spacer that places it further out away from the timing belt pulley. I recomend using the H23 part (not shown), but with a few washers (used as spacers) the H22 pulley (pictured) can be used correctly.

If you are reusing the H22 part, MAKE SURE THE PULLEYS CLEAR EACH OTHER! This is a common mistake and can be catastrophic. When reusing the h22 balance shaft tensioner pulley, the pulleys must not touch! if you are using a h23 balance shaft tensioner pulley, there is no need to worry. it is already spaced properly.

Reinstall the balance shaft tensioner retainer.

Manual style tensioner in place completely. front and side views.

that is such a good writeup. glad it willl be somewhere it will last. *cough* sticky* cough** cough*. the collectiveracing link didnt work for me either. 2.2 did you do this already when you swapped??

yep. These pictures should never go down.....atleast unless SHO goes down

prelude1897 · 11-30-2005, 12:50 PM

This should be a sticky if it isn't already...I've already done this conversion myself

Boosted521 · 11-30-2005, 06:54 PM

it's going in the resource thread. thanks blake

11-30-2005, 07:38 PM

nice write up and pics. please sticky this.

i've done the conversion here as well but it was no where near as easy as it looks because my engine was still in the car.

Dem1K · 05-15-2006, 05:41 PM

so that parts list is just for the swap only, right? Cause I need to supposedly replace my auto-tensioner (which means I need to replace the timing belt and water pump). Are those not included in that parts list? I need to know all the parts in order to get all this fixed.

btw, awesome write-up

Honda4Life · 05-16-2006, 07:47 AM

I believe that is what you need in place of the auto tensioner.

xPhax · 05-16-2006, 12:39 PM

Is the h23 balance shaft tensioner pulley included in the parts list?

Dem1K · 05-16-2006, 01:43 PM

it looks like there is a timing belt in there also? Is that the same belt that I need replacing when doing this service? Looks like I would need those parts, and then the water pump?

lambolude · 05-31-2006, 02:41 PM

how about a specific complete parts list including both h23 tensioners and both belts?

preludesh2000 · 05-31-2006, 04:58 PM

is there any kind of maintence to a manual tensiioner...such as tighting it ever so often....
or is that just the name itself "manual tensioner"
does it self tighten also ???...with the spring

JLude · 06-01-2006, 07:06 AM

Thanks bro! I'll be using this when I change my timing belt at 85K

Cruiserdude · 10-23-2006, 09:52 AM

Yeah, just looking through the resource thread here and I echo PreludeSH2000's question: Does the manual tensioner ever need re-adjustment? I was under the impression that it does not, but then a local mechanic friend of mine (who really knows his shit) said that as far as he knows, a manual tensioner would have to be re-adjusted periodically.

Cruiserdude · 12-19-2006, 12:08 PM

*bump* Still wanting to know for sure, as I'm about to do this. I've heard different things from different people, all of them very reliable sources. Do I ever have to readjust a manual tensioner after initial installation, or not?

98vtec · 12-19-2006, 12:33 PM

i dont see the need in retightening unless something out of the ordinary happens. The belt will eventualy stretch enough to where you may need to retighten, but i dont see that happening anytime soon with a new belt.

Honda4Life · 12-19-2006, 01:30 PM

My question is, What is part #14521-P14-A00 Plate/Adjuster used for? I have helped 2 different people do the swap and never been able to figure out where it goes.

It is listed as one of the parts needed, but it not used in your write up either. I have seen other people on other sites list it in swap kits for the H22 also.

Thanks,
Mike

That's the A-bracket you told me about?

Yes sir it is the one we discussed on the phone.

gfresh86 · 12-19-2006, 07:45 PM

another question is how would u be able to readjsut the tensioner? would you have to take apart the timing covers again?

cinci-91-H · 04-15-2007, 12:28 PM

In Pic #18 & #19 there is shown a small threaded "pivot shaft" that is shown to be threaded into the block. I am doing this conversion and ordered the parts list posted here. I received a small plate not viewed in any of these pics. It appears to bolt to block right where the auto tensioner bolted, the bolt pattern is the same. That "pivot shaft" did not match the threads on my block where it is shown in #18 & #19 being installed. It did however fit the bracket (bolted where auto tensioner was), I believe that this is how you lock the pulley into position on a h23. On this application, however, I am finding that the belt is already pretty tight at full loosen on this bracket.

My question:

Is there an additional part # that I need to order to get the piece from #18 & #19 ?, I think I need something there for the timing tensioner pulley to pivot on.

anyone follow what I'm saying ?, I'll try to get some pics and put them up.

daluder · 04-15-2007, 01:38 PM

anyone wanna do this for my lude??

Lil_Black_Lude · 04-16-2007, 05:52 AM

This will probably sound stupid..but what is this for?

1fastlude · 04-16-2007, 07:49 AM

Hey Mike(Honda4life) can u give me an quote on how much i'd be lookin at for all the parts for the conversion?
Thanks, Kevin(1fastlude)
