I got the Aisin TKH 007 Timing Belt Kit

I just got some questions. I know it's crucial to replace the Timing Belt and Balance Belt and the water pump. I did however go ahead and got the Honda parts instead for the belts. I also got some honda seals for some reason was not included in this kit. The honda seals that I got are Cam Seal, Crank Seal, Rear Main Seal -Maybe called also the front seal, and Valve Cover Seal (actually not honda but fel-pro for Valve Cover Seal). I had heard some times some seals should be replaced on the second or third timing belt job. Or when you see the leak or suspect the leak. Now I do have some drops once in a while from the timing belt area. So I thought it might be a good idea to replace the seals. It does make the job harder (there is no complete video on youtube showing the whole job of this). These drops might come from the Valve Cover Seal more likely? Not sure.

But the more important question here is: About those two tensioners and those springs. Should I replace those? I'm not sure they are honda parts? How long do they last? I think they might be crucial, because if they ever fail than the timing belt will fail. If they should be replaced, should they be replaced by honda parts? I got to hurry, because now I'm debating to return that Aisin kit. Although, I'm sure it's probably likely that the tensioners are quality parts in the kit. But to be safe should I replace honda parts? Or do they need to be replaced? Problem is, if they are bad parts, they might not last as long as the Honda parts.

Is it necessary? I think it's a strong possibility that there was 2 timing belt jobs on this car as indicated by previous owner. I don't know when the last one was done, but I can tell you my guess is from 2005 to 2010

 

I lost count on how many of these I have done and don't recall replacing a tensioner or having any come-backs for tensioner failures. a spring maybe if it was damaged or stretched.

Always the seals- cam, crank, front balance shaft and the o-ring style gasket on the rear balance shaft housing. always the waterpump and a new thermostat as a set. always a new valve cover gasket set.

If it needed it a new timing cover and/or cover seals.

and there is a retainer plate for the front balance shaft seal that was not included from the factory, but a dealer fix as the seal tendeds to walk out over time and start leaking prematurely. most aftermarket seals include this last I checked.

 

Okay, I'm having trouble finding the part for the "o-ring style gasket on the rear balance shaft housing". I did find a part called 13500-PTO-J00, I'm assuming that is the rear balance gear housing with everything. And the gasket in this? But I don't want to buy that complete housing? Can I just buy the o ring that goes in there. What does this o-ring look like? And what is the part number?

He points to O-ring in this picture? Hmm? Well, what part is it?



This O-Ring. What part number is this. I can't see what it looks like?


Update: okay, that rubber o ring that goes in there for that part number 13500-PTO-J00. Kind of looks like a water pump gasket. Now I can find that part on hondapartsnow for case gear set. Only problem is I don't need the whole case set gear. Even if I did it appears it does not come with that O-ring. Is that a O-ring? I'm looking for the part as we speak. It appears that I did find a timing belt seal kit. That includes that, it's called TC214.E7. But I'm not finding the OEM seal or o-ring of it. Because I have also researched when you don't use the honda genuine part it could only last 24K in miles according to a review of this part "dorman-counter-balance-shaft-seal" part 917-006 on advanced auto parts page. He stated his seal went out on 24K, but when he found the OEM part it lasted 100K plus more before he sold the car.

 

Okay good news I found something. Here is what I found for the OEM parts of all the seals

15114-PTO-003
Oil Pump Gear O-Ring

91233-PTO-003
Balance Shaft Seal

06923-POA-306
Engine Balance Shaft Seal Kit

91212-POA-004
Crankshaft Seal

91213-PTO-003
Oil Seal

 

Probably best to do as Hondamark35 says.

If you are replacing the belt every 100kish miles, cheap tensioners work fine as they get replaced before they can go bad.
In an unknown situation where you don't know what has been done, it can be best to just do everything so that you don't have to go back in and redo your work for one little part and a few $ in parts.

When I do my own work on my 80's & 90's Honda's, I only replace the belts unless I hear a bearing making noises when I spin them by hand or visibly see an issue.
I have multiple Honda's with near 300k miles with original tensioners, water pumps and seals. Often after replacing a non leaking seal, then it starts leaking in the future

Side note, I still have original alternators with 250k-330k miles. Just replace the brushes rather than putting on a cheaply re-manufactured alternator. This just shows that Japanese bearings are quality.

 

Okay thank you. Well, perhaps the theory on that is. It is possible if you replace a seal that wasn't leaking. Then maybe it wasn't done with Honda OEM part or it was not done properly. I do however know that there have been drips near the timing belt area in my car. It's insignificant to me. But more significant to a picky land lord. My guess is when I take a look at things inside, if I see evidence of a leaking seal. I might replace that seal. I can't guess what seal it is, so I have to buy all seals that are related to the honda timing belt area. Including the Valve Cover Gasket, that's a possibility. I heard the bottom seal is rare for it to leak.

Now that I know the tensioners don't really need to be replaced. I can go ahead and return that Aisin TKH 007 Timing Belt Kit. But I then need to find that separate part. "always the waterpump and a new thermostat as a set" I got to make sure I find this first.
Thanks for the information.

"I only replace the belts unless I hear a bearing making noises when I spin them by hand or visibly see an issue"

Thank you for that tip.

"Side note, I still have original alternators with 250k-330k miles. Just replace the brushes rather than putting on a cheaply re-manufactured alternator. This just shows that Japanese bearings are quality."

Hmm, interesting, I wonder if my alternator is the original? I have heard of that too. That's a great idea.

 

You were right. I now have a leaking seal. 3 months later. I should have left the gasket seals alone. It took a lot of time doing them. The irony is if I had left them alone, it would probably be okay even going past 300k miles.
I recommend not doing the crankshaft seal. But I don't think that is the one leaking. I think it's this one Balance Shaft Seal. It's maybe because I used the kit from ebay. And not the one from hondapartsnow. Both were Honda OEM. If not, maybe I did the install wrong. The balance shaft seal is really hard to get in, because it's in the middle of the car frame. I'll update later to see what is happening. > > >
