Oil drain plug

[SMBH]

Please can any one tell me the torque setting on the sump oil drain plug, did a search and came up with nothing. Thanks

Here is a link to the service manual. I did a quick scan, to no avail. It's got to be in here somewhere.

There is a fable. Someone asked a centipede how the dickens she managed to keep
her multitude of legs moving in perfect synchrony. The issue had never occurred to her; she simply did what came naturally. When she faced the question, she concentrated on the process of walking, and ended up in a distracted tangle.

I feel like the centipede. I have been changing oil in many motorcycles since the Kennedy administration, and I have just reached for the wrench to put the dang plug back in, wrenched it tight enough, and ignored that plug until the next oil change. No trouble ever.

Now you have me wondering what to set my torque wrench to ...

Nah, I will just wrench it until its tight, and carry on. Mr. Honda never gave me a crush washer, so I do not use one. Mr. Honda doesn't make it easy to find a torque setting, so I won't bother researching it. I use an ordinary wrench, not overly long, and turn until the nut feels right. I am sorry I cannot be more specific.

In a little while, I am going to put oil in my CB-77, which has been in pieces far too long.

It's all about risk versus return, right?

Risk: 15 minutes of your time wasted reading.
Return: Not siezing an engine due to oil starvation or stripping the sump pan, which on an antique, may be made out of unobtainium.

To each his own.

90407-259-000, gasket , drain valve (crush washer) as originally designed by Mr. Honda and shown in all my parts books and still available from Honda. I believe the 6mm case bolts get torqued to. 6-9 ft/lbs but don't know about the drain bolt. I just use a new crush washer with each oil change and tighten by feel.

A 12mm standard grade bolt, lightly lubricated, calls for a torque of 29 ft/lbs. in most charts. Regards, Chase

Thanks guys for the input, I have over the last 50 years restoring and running M/C most british I have had much call for a torque wrench in fact had a Triumph T140 and did a complete restro on it and never used a torque and I had no problems at all.

My reason for asking is I have a new love in my life the CB77 and the big problem is the avalabilaty of spares it's not like a old Triumph one can get almost anything for them but this Honda well one can not even get a new primery chain for it and most of the spares are so expencive, I just purchased a ignition switch from CMS and it cost around £90.00 that made a big hole in my pension.

I do not need many spares for this CB77 it is in very good condition im just being cautious doing work on this bike.
