2005 F4 oil leak sump removal

I've searched the forums for a complete answer and haven't been able to find a post that gives a step by step on how to remove the F4 oil sump cover. Ive had a leak coming from the sump gasket for some time now and have tried to torque the sump cover bolts to spec but it still leaks. I bought a gasket and plan to change it. This is the first thing I'm doing to this bike myself so wanted some pointers. I have to remove the entire exhaust (front to back)? If so removing the headers requires removing the radiator? If someone can give me a step by step that would be very helpful. I did see the posts about making sure the center bolt is also removed from the sump before trying to remove it. I realize the reason for the leak is most likely the side stand causing flex in the pan.

So my question is what all has to be removed before I can get the oil pan off? Thanks for the help.

What's wrong with the instruction in the Workshop Manual?

Just your exhaust and the rear brake lever unit, and of course the sidestand I added some Hondabond to the new gasket on both sides, has not leaked since.


Its really easy job to handle, even if not familiar with wrenching before.


Good luck.

I think the easiest thing to get wrong will be applying too much torque to the bolts when you are reinstalling the sump. The temptation will be to torque them up pretty tight and not using a suitable pattern or order. As Chuck has said, refer to the manual.

It ain't what you ride, it's the way you ride it.

I all fairness, Chuck, the manual is pretty lacking when it comes to the oil sump. It certainly was in the Brutale manual, and I just looked in the F4 manual and it literally takes up a 1/4 of a page. The only instruction is to remove the bolts and the photo shows the entire engine removed from the bike.


I guess I am saying I sympathize with the OP because I just did this on my Brutale and had the same reaction, "What do I need to remove in order to get to the oil sump?" I couldn't find any instructions beyond, "Remove the oil sump by unscrewing the 6mm fixing screws."

Thanks for the info. I’ve looked at the manual and it says remove the radiator to remove the headers. I agree with Ic_Brutale, the manual lacks any specific instruction regarding oil pan removal. Yes will be sure to torque the bolts accurately. Just curious can you get the headers off without taking the radiator off? That seems like a huge pain. This is the first bike I’ve had that requires so much effort to remove an oil pan.

You can pull the headers without pulling the radiator...I did it on my Brutale.

1000 miles later I repaired the coolant leak caused by the fan rubbing the radiator where I bent the mounting bracket removing the headers without pulling the radiator.

Do yourself a favor...pull the radiator.

Much easier than fixing the problems that resulted from being lazy and not pulling the radiator.

I always remove 3&4 when changing the oil filter on my Brutale
I have an Arrow Thunder system
Remove the 2 pipe springs between the head pipes and mid pipe
Remove the pipe mount to the frame plate
Remove right foot peg mount, pull everything to the rear
Lift the lower radiator mount off the peg, push the bottom of the radiator forward
Remove the 12mm nut on the pipe clamp.....pipe comes right off, not touching the radiator

F4 pan removal
Pull the pipe springs between the head pipes and mid pipes
Remove the 2 bolts from the right frame plate
Put.a strap around the rear of the cans and the tail.......remove the 2 can mounting bolts and pull everything to the rear,
lowering the mid pipe
Loosen the 12mm clamp nuts lowering the head pipes, remove the oil pan

OF COURSE I'M ASSUMING YOU USE NEVER SEEZ ON YOUR PIPE JOINTS

I bent my fan when I was removing the original exhaust....no mid-pipe - one piece headers/cat.

And the photo shows his bike has the one piece header pipes as well.
