Oil Drain Plug

[KVF 700]

i know this was discussed before, but i didn't have any luck with anything.

the drain plug on my kawasaki is worn out, or maybe its my fault for over tightening it. anyways last time i changed the oil i had to lock tight it in there because the threads are on there last legs.

i remember someone saying you could get oversized plugs at princess auto, but they didnt know what i was talking about when i was there.

maybe i should just take it in and tell the mechanic to deal with it.

NO!!!!! Don't take it in!!!!

Once you have drained all of the oil, get yourself a "Heli Coil" kit.
Bore out the old hole and insert the new one.
Also cut your drain plug close to near 1/2
This will allow better flow & a tad bit more cooling.

ha ha alright. im scared that i will get shavings inside the engine doing that though. also how is cooling improved?

Ya I am curious on the cooling as well

If you drill up, & dump a CHEAP litre of oil back through her. You shouldn't get any filings in the engine.

Sorry.... please don't think that you'll get 15% more cooling!

As stoopid as it might sound......
it just another barrier that your oil doesn't have to go around.
It isn't much..... but every little bit helps

Been a mechanic since '93,.. I still don't understand how a LARGER drain hole will help with cooling,.. adding a larger oil cooler,. larger oil filter yes.

Am I missing something

Not a larger drain hole.... but a shorter drain plug.

Congrats on your up coming 20th year anny(few more to go), for being a mechanic.

If you take it to the shop they will likely heli-coil it anyways. Pressurizing the crankcase and using grease on the flutes of the tap and drill bit will minimize any shavings in the crankcase. The bigger problem is the heli-coil is usually longer than the crankcase is deep; if the heli-coil is run in too deep you can't drain all the oil out during oil changes.

Another option is to drill and tap the existing drain bolt and use a smaller bolt as drain plug, inside the old plug. Use green lock tight to permanently lock the existing drain plug in the existing threads and use copper coat on the new plug and threads.

thats a nifty idea...probably could only get about a 1/4 inch hole drilled though at best. also would have to maybe shorten the existing plug so all the oil would drain. nonetheless, good idea.

had the same problem in my 69 cougar. i found a plug that uses compression with rubber. it's muli fit and should work for a quad. i tried the heli coil route and it did not work as the threads are not deep enough. i beleive it was from acklands, some quick lube oil change places also carry them.

Canadian Tire has those kits in their "HELP" board. Using those rubber compression rings is not a good idea as they like to melt and now you have a new problem. You can get those phenolic resin(red) washers to shorten a drain plug down a bit as they are rated for high temp sealing.

will likely work, only you will never know if the drain plug has fallen out, until to late. lots of mud, sticks and crap, i would try the hella coil first.

thats true, it works well on the car but unless it's completely concealed maybe not such a good use for atv. you can also get tapered plugs, plugs that cut there own threads as they go in, and expandable plugs.

Helicoil will have a repair for the drain plug. Hands down best way to repair the threads to oem. Spread grease on flutes of repair tap and around inside of hole before drilling or cutting any metal. Helicoil has different length inserts for different depth holes.

You should have no problem getting a helicoil the size you need. Above should be the kawi part number and size for the drain plug. The link I provided above should show you the pieces you need for the insert. I would even try a kawi dealer for the part. However you will need the helicoil install tool to install the insert. Cdn Tire probably sells it.

thats a load of BS i would like you to try and prove that theroy with a heat gun or any other way you see fit. I would like you to prove this. I am willing to bet that there is no differance in oil temp.

I understand and acknowledge that one of the functions of oil is to provide cooling.
Cutting down the drain plug is not going to assist or enhance this function. Someone fed you a big balogna samitch and you ate it mayoneese and all.
