Gentleman. If you're anything like I am, you have watched every video regarding the Rocket 3 that has been made since the birth of the beast. And then watched them again...

I just finished the YouTube video series titled, "Oil Change on a Triumph Rocket Part 1 through 8." Is this spot on information regarding the oil change process? I'm not asking about his choice of oil and filter. I have a bead on that. I am also tracking that I need to buy the washers and the O-ring. If someone has a reference to another thread that might have some additional information in it I would appreciate it. Thanks and have a great day.
 
I've never replaced my crush washers or o-ring (46,000 miles). I did have one of my crush washers start leaking on the way back from the Maggie Valley RAA meet last year. Had to wrap it with thread tape. It's still like that. I will replace them next oil change. I think you can reuse them a few times.
 
The washers are made from a soft aluminium that crushes to make a seal when torqued correctly. The crushing makes them more dense meaning harder, the more they are reused the hardness progressively increases making a seal less likely unless over tightened. Thats why they really should only be used once. Over tightening puts you on the road to a stripped thread.

This is also true of the crush washers on either side of the fuel feed line on the tank. I tried to use mine twice, torqued correctly. Luckily I pressurised the system before lowering the tank and found the union dripping, not a lot but enough. If the tank had been down before pressurising I wouldn't have noticed it and the drips would have been going strait on top of the motor, not good.
 
The washers and o ring from Triumph are expensive. I've found it pretty easy to get the smaller sized ones elsewhere but not so the larger one ( or the O ring). Can anyone tell me the measurements of the larger washer.
 
I'll try to get a handful of those washers and O-rings when I close the deal on my bike, while I'm still holding the gun a little.
 
If it drips, washer. Hell, I don't even know her.

I've had to replace many stripped oil pans due to others improperly torquing the drain bolt. So if you have the touch of a gorilla when tightening bolts, I would strongly suggest to use the crush washer. The price of the washers are far cheaper then the replacement of the sump pan.
