I recall you debating with yourself about which flywheel to use, and thought you had most of a second '81 bike. Bugger.

From the sounds of the lockup after running dry, you may find little to salvage from your current 'box. Perhaps Matt might have a spare, or the Evil Fleabay?

Bummer Rob.
Perhaps a s/hand box from uncle Matt?

Rob, that sucks big time. I did this once to a good friend/customer. I performed the work myself rather than pay a (my) mechanic. Running the shop meant that I was interupted often. He brought the bike back in his truck a month later due to "It won't shift" symptom. Yep, I failed to fill it with oil, but the plug was in it.

When we pulled the plug, metalic dust fell out and lots of it. Only the case was useable and rear cover parts. He had gotten a lot of miles because his only rides were into town and home, only a couple of miles, so it didn't get hot.

We had had a fear of doing this and I was glad that it was me, rather than a mechanic. We came to the conclusion that the only way we could protect this from happening again was to first remove the fill plug. Then leave the fill plug out until the last moment in a service. Possibly leave it with the key would be even a bit better.

It never happened again, but then I was very seldom doing a full service after that, good thing too.

Safety wire won't help if it was just memory. A new crush washer won't either. We always replaced them on customer's bikes, but seldom on our own.

I replace crush washers every time, esp. since I found that Huckys could supply me with the copper washers that actually DO crush!

Yes, this is another case of "that probably won't happen to me, twice".

That is weird, because I checked under the bike for oil, and found none.

I'm not running across my drain plug anywhere in the shop, either.

Fresh rebuilt transmission from Psycle is $895.
Matt didn't answer his phone.

Rob:

I am sorry to be so blunt about this, but when I read your post about the lack of drain plug....I had to laugh. What else can you do? If it had happened to me (which it certainly could), I would just have to have a sense of humor about it.

I can't imagine that this plug just fell out and you did not notice all of that oil. Especially gear oil.....that stuff smells up an entire garage with just a few drops.

Thanks for sharing honestly.

It would be worth getting into that tranny to see what happened, but my first thoughts are that you may not want to invest the parts and labor into a transmission that was run dry until it locked up. It would be cheaper (wiser) to get a good used one and run it.

Rob, I read on another site that "all the trannys from about 77-80 are the same"...They didn't exclude the R65's from the list.
Do you know if any other tranny will FIT your bike?
Since you have the heavy flywheel, etc, I wonder if it might be possible to find a used tranny for you...as in: from an ENGINE that ran without oil?.

Jean, I got your email and sent you a reply.

Yes, Type 248's used the same gear box as the rest of the line for a given year.

I've heard that folks like to buy R65 transmissions because they don't see the HP that the bigger bikes put through them.
Do you think someone will want my "R65" gear box? :lol:

That is OK, Blaise, I am surprised at how well I am taking this, really! Of course, this is going to put a serious dent in my La-Z-Boy love-seat budget...

The more I think about it, that drain plug must be in the garage somewhere, along with a full bottle of gear lube.... :evil:

I like Vanzen's advice:
"I'd be looking for a comprehensive pre-flight inspection routine first –

And hopefully my mistakes will help others.
