How many times can the driveshaft drainplug washer/gasket be reused when changing the final drive oil? Thanks.

 
It's the same crush washer as the oil drain plug. Given the fact that it's a crush washer, I would only use it once.

 
I switched to copper washers and anneal them each time. they will last forever.

 
Stock crush washers on every bike I've ever owned and I have never replaced them and never had an oil leak.

 
Per the Service Manual; inspect the crush washer, if damaged, replace.

The crushable side of the washer is aligned with the bolt (which is forged and not perfectly flat; when the washer crushes it conforms to the irregularity of the bolt), the other side of the washer is perfectly flat and aligns with the machined (i.e. perfectly flat) of either the rear pumpkin or in the case of the oil pan the oil pan hole.

No need to replace every time.

Thanks for the replies. I used a new washer on the drain plug and re-used the one on the filler bolt. No leaks so far.

 
I service the rear differential each time I replace the rear tire. Its easy to do, so if the wheel is off anyway, do it then. I have not replaced the seal yet and I'm on my third set of tires. So I have used it twice so far. The same type of crush washer is used on my other bike and all of my 4 wheeled vehicles, which includes daughters vehicles and have never replaced a single washer. I have never experienced a leak either. If I did spot a leak, I would then change the washer. If you torque that bolt down to 85ftlbs, then you deserve a leak. It is generally not necessary to over tighten any bolt that holds in a liquid. The washer [should] last if its not ruined with a heavy arm. But if they are cheap, buy a whole ****-load of them and replace the little sucker each time. The issue here is if you remember to buy one prior to performing the work.

They are $1.99 EACH at my local dealer :blink:

But if the prices on FJRGoodies are still current, you can get them from Guru Glen for $0.48

+1 for the Wee meister. Just check for damage & torque to spec. All OK, all the time, everytime.

EDIT: should mention that I use new washers for banjo bolts though. All others, we let 'em ride.

Is an extra buck that you save really going to make your day?
It's not the savings for the cost of the washer so much as the true cost of acquisition (time & $) and the real risk being run. Cost is not just $ for the washer, it includes the $ for acquiring and bringing the washer to where it will be used as well as the time associated. It is also an assessment of the "real" nature of the risk being run. Crush washers are meant to seal better than other washers to prevent leaks. I've NEVER (and that's 40 years of never) had a leak with a reused crush washer and I've got many, many experiences behind that claim.

Now, I certainly don't want to look like I'm preaching, but what I'm telling you is the absolute truth w/o hyperbole. I DID go back and put the one exception to what I said about these items: I DO use new washers for banjo bolts because of the high pressure condition inherent in where they're used (brake lines, etc.). Oil pans are not typically high pressure systems so you're not risking much by using the old washer.

Cheers,

That is funny.

But any further discussion on this will result in a dog pile. What ever works for you is great.

Yup...it was delivered tongue-in-cheek...a riposte to your 1$ line. What goes around comes around...right? The rest was dead serious tho'.
