Thank you so much for this video, it help me to fix a botched timing belt job by a local mechanic. Now my engine is back in time/balance (They had the oil pump pulley hosed), running smooth as butter.
They obviously don't mention the mark on the rear balancer sprocket cause it will lign up and still be off... need that bolt in that hole that I had no idea was even there. Glad you posted this video, I now know I gotta recheck it, installing a belt kit. Wished I had seen this earlier today, I could of finish the job.
that is why you need the bolt, because if the bolt is inserted into the shaft (74mm mark on bolt) you are good to go, you don't need to look at the other marks. If you go just by the outside marks and not the bolt into the shaft it technically has a 66 percent chance of vibration... It's not that tough, stick the bolt in before you remove the old belt (assuming that was correct to begin with), and remove it right after new belt is put on, before you set the tension.
Thank u for taking time and showing us exactly what's going on with the boroscope. Man u saved me a big headache trying to figure this out with the instructions, they should at least state that it will line up every three revolutions of the pulley because it has gear reduction gears. Cheers 🍻 to u
I think the better and easier way is to mark all the pulleys with white paint (when the belts are still on) or something and then make sure you dont touch them until you install the new belts. My friend has been a car mechanic for 35 years and he said he has tried both methods for at least a hundreds of times and the much easier way is to mark them by yourself.
If the balance shaft is out from someone doing it wrong then marking everything and not disturbing anything doesn’t work you have to start from square one Been doing mechanic work since 1986

Finally !!! Some crystal clear instructions on my specific issue. I owe you a footlong sammich & case of wheat n' barley..lol. Killer snap-on snake cam, gotta get me one of those.
You have helped me out so much .. I believe my balance shaft seal is leaking, the one that you have the snap on camera in .. I saw a tip on UA-cam about finding leaks by cleaning the oily surface on the engine and spraying aerosol foot spray (ones that spray on “white”) and I see the, “now white surface”, turn yellow from oil.. and now I know when I change my timing belt and all the goodies that go along with that .. I can Change this new problem on my h23a1 .. thank you so much man!! Keep up the great videos !!!
Extremely beneficial. The issue, of course, is missing the point that a bolt is supposed to be installed PRIOR to belt removal. Your notice that after about three rotations, the marks line up with the bolt hole was what I needed to see. I was about to mess up.... thanks.
Gene Friedman it doesn’t make a difference if you don’t disturb the pulley. BUT if you don’t know that a bolt is supposed to be inserted to keep it from turning, and the pulley IS disturbed, one might just align the dots. It is align-able without the bolt hole being in the proper position. In that case, the balance shaft will be in an out of balance position when the belt is installed. Some folks have done just this and not noticed any adverse effects; trust me: if I had done it, my car would have run like poop... 🤣
Lol... yes that is correct. Thats why this video is so great as it shows clearly what is going on inside the hole as the balancer turns. Best to not guess which revolution its on and put a bolt or screwdriver in the hole.
Thank you, thank you, thank you! I was having a hard time making sense of the instructions in the factory service manual while doing this part of the job. These instructions/explanations were by far the clearest i found anywhere. Made the job so much easier. Thanks for a very helpful video.
It works fine the way the manual states. Inserting the long bolt into the rear balancer shaft stabilizes it in position and the marks on the gear and oil pump housing will line up. No need to overthink this part. A problem arises if you pull the rear balancer driven gear to replace the O ring either without having the rear shaft "pinned" with the bolt and/or in not paying attention to how it is re-in stalled. That is when the marks on the gear and the oil pump housing become important. They insure that the gear is in correct position when you bolt back on the entire driven gear housing. After that, the bolt will stabilize the rear shaft in the correct position for installing the belt every time.
WILEY Motorsports S.P. That’s where I am too. The key is to pay attention to detail. And to take your time on everything if you don’t believe that then your just a different kind of mechanic.
The manuals mention a second mark that you have to align with the front mark you show on the back balancer sprocket. Basically on the sprockets you need both marks lined up.

Did it turn out OK with no unusual vibrations? I had a valve job done by a shop about 6 months ago. It came back running much better, but unfortunately with a *new* vibration. I think they screwed up the rear balancer. If they watched your video I think they would have been OK. I think you are right that the most important thing is getting that bolt or pin aligned. After seeing this I may try it myself.
Very helpful video. The 12mm sealing bolt for the maintenance hole on my 1998 Prelude is hopelessly stuck and the head of the bolt is torn to shreds from repeated attempts at removing. I've tried running it without the balancer belt and am not happy with the extra vibration. It looks like I'd have a one in three chance of aligning it correctly simply by lining up the marks on the rear balancer shaft. Anyone else have any experience aligning their balancer shaft system without the inserting the maintenance bolt? Another site mentions "when it's at TDC the rear balancer shaft will stay there naturally & not try to fall over." If that is indeed the case, it will improve my odds of getting it right in one try.
For those interested, I did manage the alignment without the bolt using the method described above. It wasn't plainly obvious which of the three positions to pick though. I picked the one that best matched the description of "stay there naturally..." I wouldn't recommend using this method, unless your sealing bolt is stuck.
Hello Friend. I'm in Brazil and I have a Honda Accord 95 when I disassembled my engine I noticed that the balancing shafts and their bushings are very worn, do you know what is possible to do? Sorry I'm using google translator.
Thank you for this, but I'm still stuck. When I replaced my engine I simply just followed the markings without using the bolt technique and my engine is super coarse. So just to confirm, there is only one rotation possible where both, the markings match AND the bolt will go in, and this is the correct setting? As for the front shaft, is just simply matching the marks enough or is there a possible way to get it wrong even with markings matched? Thank you!
Great video. The Front Balance shaft is not offset, its straight thru. As to the Rear is offset. Your turning the oil pump and it's geared to the balance shaft. 3 turns and thats it. But yes its a very unwell written manual. Sorry 3 1/2 years too late. lol

what difference does it make when you insert the bolt? As long as it goes in 74mm and the bottom mark is aligned you are good to go.

How cool thank u so much man I needed this ASAP and you mad it happen thanks again!!!
Thanks dude, I get you. Saved my butt from some heartache....
thanks for the clear instructions.. just what I needed.. 😃
Thank you sir. Out of all the manuals i have read, they do a poor job explaining this.i have two h22s
whats interesting is certain model year Hondas have the mark on the pulley but no outer mark on the block for the rear balance shaft
The bolt is just to be used as a holding pin. And the hole only lines up one way because it can only be one way so it balances correctly

Thanks for the video man ya saved me from an brain anyarisum.
wish i could get ya a beer, Cheers buddy!
im in the process of doing this. thanks for the insight. the hayes book isnt very clear.
Good good good good good
Thank you very much
Then it's gear reduction, 3 to 1 ratio. You have a gear that operates another gear that has the hole in it.
Behind the rear Balance gear is another gear, that is why the mark lines up every 3rd turn. the front gear is bolted directly to the balance shaft.
the top marks on the rear Balance shaft are for alignment of the the belt gear with the shaft itself when it is removed for doing the oil pump.
awesome video... thanx
Its how IT lins UPS 3 time
overthinking it... use a Phillips screwdriver in the hole.
Whatever works for you.
Individual results may vary.
I love you
