washer size

[sgull]

While re-assembling the timing tensioner business during working on my car (Honda Accord) I've discovered I've somehow misplaced (lost) a metal washer, shown as #28 in the following diagram. The parts list describes it as "washer 10.3x25" just as I've typed. I'm fairly certain I recall this metal washer as being fairly thick, maybe 1/8" or so. There's no dealer locally from where I might obtain this part (if they even happened to have it in stock) and I hate to have to go to the trouble to order it and wait if I can avoid that necessity. I'm wondering if probably the local hardware store would have what seems quite possibly otherwise to be a standard type/size typical steel washer if I were to check. It would help if someone here might know for certain what that "10.3x25" indicates, these details which could be of help to me here, as I am unsure (clueless actually). Any comments appreciated.

I don't know what the numbers signify, but if you have a Honda dealer nearby, the washer is under three bucks.

Thanks Erampu but as I mentioned there is no local Honda dealer, which is why I was hoping maybe the local hardware store might have the washer if it's otherwise a relatively common size, so I wouldn't have to order one through Honda and have to wait if I can avoid it.

That diagram is difficult to view from my phone, however, I'm wonder what is stopping you from buying a few washers that fit your fastener and stacking them to achieve relative thickness. This is assuming the thickness isn't critical in the assembly.

10.3 is the hole diameter. 25 is the whole diameter.

That is how a washer is measured.

Not sure on thickness though if it is special or not.. Of if the hardware store has different ones in a certain size.

The thickness on that washer is pretty critical too thick and it will cause the bolting to lock the tensioner in place,too thin and it will allow it to wobble with the bolting tight.That washer and bolt is the pivot for the spring loaded tensioner.Don't cut corners here get the right part.

Keep looking for that washer, it's going to be the last place you look....

Ask on Honda-Tech.com, someone there might have on laying around/know about how thick it is.

What about finding one off of a junk motor? I know you alaskan's like to hold on to stuff theres gotta be someone near by with a blown up motor.

I'm 100% for finding the correct washer. But you could make one if you have a 1" hole saw for electrical sized knock outs. Drilling a hole in a piece of scape metal will leave you with a 1/4" center and a 27.4mm od, then if you can drill out the pilot hole.

Please don't blast ne for the suggestion guys, that's all it is..a suggestion. Figured with the OP's location being Alaska, the local pep boys may be a bit out if reach.

I know it's not what you want to hear, but Chad is right. Most of these "special" washers
can pretty much be described as bespoke parts. I definitely advise you get the Honda washer,
Esspecially as it's only a couple of Quid.. or bucks... or wherever you're from.

Also, even if you do fiind an alternative, there will always be this nagging doubt inside your
head wondering if it's working ok and could it fail at any time, or have a minor problem
and cause the belt to slip a tooth... Or it could all work just fine... Who knows.

**** it up... Be inconvenienced for a few days and get the right part, When it's all done
and dusted, you will be happy you did for the peace of mind.

Hey thanks for all the helpful suggestions/replies. I'm leaning strongly toward Rico and Chad reasoning for just breaking down and inconvenience myself by taking the time/trouble of getting the known correct part if I still can't find that dang washer in the last place I look as EOC_Jason said it will probably be.

With the input here so far, and having a chance to consider if further, trying to guess whether some alternative washer might or might not work and never really knowing if it'll cause a problem (having that nagging doubt) makes it easy to decide here against that alternative. Probably fairly critical, I would tend to agree, that the washer be the exact special one in regard to thickness at least.

I know the exact Honda part number, I've already looked it up. If I buy one it'll cost me a few bucks and the shipping about 5 bucks. And will have to wait a week to get it. I happen to live in small relatively isolated community where there are no junk yards and sparse junked vehicles sitting around so finding a used one off a junker is doubtful, although of course a quite sensible suggestion otherwise.

I'll probably order it, pay the 7 bucks, wait a week for it, take it out of the package and install it, then find the old one sitting right where I put it.

Does bolt #23 go through washer #28? The exploded view doesn't show it that way, but I don't see where else it would go.

If the washer was anything special, or a special thickness, it would be noted on parts list, sometimes with an abbreviation like "(sp)."

I would go down to the hardware store and just get a hardened washer to replace it and never think about it again.

Actually, the tensioner adjusting nut (which is part #26), which has a flat base on it, tightens onto the washer (#28), and secures the tensioner pulleys (for timing belt and balancer belt) on the threaded shaft through which they're installed.
