How much oil does it take?

flynbrian · 09-24-2007, 05:07 PM

Newbie to Honda and the forum. I just bought a very clean 05 trx450r with low hours and w/o the manual and I was wanting to give it a fresh oil change and filter before I start putting hours on it. I read on the forums that the manual recommends using HP4 10w-40 for the engine oil and HP Transmission for the tranny oil. I am wondering how much should I buy of each to change both and does anyone know where I can download or view an online manual that explains what goes where and how much. Thanks

a little less than a court just drain i pore a little oil in when i got the filter n plug out to get some extra oil out thats dirty,then put plug back in n filter then fill it up between L-H then run it let it sit for a while n check it out
i use the hp4 for my engine , and gear saver for the transmission on the transmission side u use oil with out MOLY cause slipping

hope this helps

the engine side is fairly easy to do. just poor until the glass shows full. i think its like .82 quarts. on the tranny remove the check oil bolt, it is on the bottom right side of the clutch cover. it looks like you can remove it with a phillips screw driver. add hp tranny fluid (red bottle 80/85) untill a little starts pooring out then just replace the check bolt. once you turn on the bike let it run a while then check your engine side to see if it needs a couple more drops of oil.

Thanks everyone for the replies, this ex 2-stroker turned 4-stroke should be able to get-r-done now. Found a manual on here to download too. Great forum.

.8 liters (engine oil) 10w-40
.6 liters (tranny oil) 80w 4 stroke gear oil

Put 650 cc in the trans! The above method shorts you oil and you will prolly strip the check bolt! LEAVE THE CHECK BOLT ALONE AND MEASURE THE AMOUT OF OIL YOU POUR IN !!

The method you use will leave the trans level low. Next time you fill your trans using your method see how much oil is left in the bottle when it comes out of the check hole , I will bet it is more than 300 cc left in the bottle!

Alot of people on this site brag about the bolts they strip or break off . This is one of those bolt that is easy to break or strip.

Anyway no offence,I personally don't like filling the trans with the check bolt method....

Dose anyone know if you fill the oil to full in the glass eye, then start it for a few mins to let oil pump through the engine and drain, and then fill it back up once it drops,. Or do I just fill it to H on the eye piece without it pumping through and leave it there. The only thing is, is that when I did that the oil dropped significantly and there was no oil left because it all pumped through the engine. I know on a blaster you fill it up, then turn on the engine for it to drop, then fill up up more so that when the engine is running it is on full.

Long story short .....just make sure the engine side oil is always between the L and H marks on the sight glass. Check the level after the quad has been sitting for at least a few minutes so the oil can drain down.

Just like he said, just keep an eye on that oil fill glass. When I do oil changes I also use my compressor to push out all the dirty oil out of the oil cooler. I use an old rubber bushing with my air gun attachment in the fill plug hole for a good seal and blow the oil out where the filter goes. If you do this just be sure to not have your air pressure set high. fill it back up using the sight glass. let it run for a little bit. let it sit for a few minutes and check the glass again. fill if needed. i used rotella 15w/40

Also on the tranny side I used the oil level plug when refilling, screw it back in and add a little more. And as far as stripping the srew plug, I also worry about this because it feels very easy to over tighten. I may start measuring the oil also like stated above to avoid possibly stripping the plug.

Okay, thanks. My plug has a hex head so I can use a ratchet instead of the phillips head, but the hex head would be easy to strip if I tried. I already stripped the philips head part so I rely on the outer shape to put my ratchet on.
