STRIPPED THREADS ON OIL PAN

HEY GUYS!

Hope everyone is doing well and staying upright.

I just did an oil change on my xj550 SECA, and it seems the previous owner may have stripped the threads on the Oil Pan (for the drain plug). It was not leaking before, so i'm sure i had something to do with (nail in the coffin) it being completely stripped. Now it leaks. I need a damn beer.

MY QUESTION:

I know I can get a replacement crankcase oil pan. Does anyone have any pointers on this operation as far as replacing it? I will have to remove the exhaust. Are there any parts or gaskets or anyting I should know of to be prepared for the fix?

Thanks for any opinions or advice!!

Quite a few on eBay, such as http://www.ebay.com/itm/1981-YAMAHA...ash=item35dbbe1a84:g:GPgAAOSwPe1T9h2N&vxp=mtr
What's the chance you could clean up the hole and tap a larger size?

 

I thought of that, but wasnt sure of the clearance diameter to tap new hole. maybe someone will read this and chime in on that question.

Thanks for the ebay link.. i saw a couple on there.

 

My vote replace ..less chance of metal chips as an added benefit you can see if you have any nasty surprises in your oil sump IE chunks of the chain guide etc, yes exhaust has to be dropped , if I recall I believe there is a gasket. Chacal at xj4ever can help with this .

 

Yes, i suppose youre right. better to know whats inside there. thanks for the thoughts. I'll do some ebaying and try to find a decent looking pan.

 

Drop the exhaust as a complete assembly. There are seals at every joint that will have to be replaced if the pieces are separated.
There will be gaskets for the exhaust ports, and the oil pan. The oil sensor will have an o-ring that will probably need to be replaced.
Beyond that it is fairly straight forward. unbolt the old and install the replacement.

I believe the torque on the bolts will be 15 ft lbs. They just go into cast alloy so be careful!

better check the book, 15 ft/lbs doesn't sound familiar

 

7.2 ft/lb per the book.

 

did not have the book in front of me at the time, but knew it was not much.
Thanks for the correction!

If it was me I would remove pan, find next size up of thread ( metric or std) and use a universal oil plug. But if you can find a used pan ....

 

I put some RTV on the washer, and some teflon tape on the thread. The seal is gone!! perfect fix til i get ahold of a used pan. Thanks for the info guys..

Im still thinking im going to go with a used pan instead of drilling out new size. Both are easy enough, but i have found a pretty cheap pan.. so might as well just go with that.

thanks again!

I would NOT ride this till it is fixed!!! Teflon tape and oil/heat do not work real well ( DO not ask me how I know..oh it was on my air cooled VW 71 Super Beetle used Teflon tape on oil sending unit it cracked the oil boss and latterly melted the tape huge oil leak ... but that is another story ) I would be afraid it let go and start a leak while riding dripping oil goes towards rear tire not a real good thing.
