Dear harley friends,
I'm new here and I greet all of you. Can you please help me with changing oil? (info only).

Last year I buy FXDBI 2006. I'd like to change all the oils. According to the instructions from manual I do not know how many species of oil I need to use. One, two or more.. I write some questions important to me.

1. Can I use the same oil for the whole machine? I plan to use this oil: https://www.moposport.fi/media/catal...729-635004.jpg

2. Did I correct understand that the engine has two oils that changing over the shutter with dipstick, and one that's change when i remove the derby cover?
2.1. How many screws i have to release all oils?

3. Does the oil I place over the derby cover can be the same as the gearbox and the machine?

4. When i change derby cover and change oil - i must every time buy a new derby gasket? (up is the first one bought with a motorcycle, from first owner).

4.1. Do i need put a LOCKTITE glue to put screws on derby cover again on engine?

5. So, i need a buy almost 4.7 L of oil to fill all oils? Or how many?

(sorry for my english). I now the questons are "dump" but i'm new in that. I hope the answers will help many people.
Thank you very much, to all! Best regards,

 

Welcome to the forum. Congrats on the new bike. It's good to see you're interested in maintenance, and I would recommend you get a copy of the factory service manual.
There are more opinions and answers to your questions than you can imagine. You should do some research and see what sounds good to you. There's an oil section where you can get a lot of info. https://www.hdforums.com/forum/oil-a.../?daysprune=14

 

Thank you. I will try to find the answer on the web. The service manual is a good solution but it is difficult to access that book in my area. But I'll try to get. Thanks anyway.

 

The three drain plugs are the same size (Hex head). The primary and the transmission drain plugs face down (vertical). The engine drain plug faces towards the primary (horizontal).

Engine almost 3 quarts, drain plug torque 168 to 252 inch pounds (14 to 21 foot pounds). Run engine 1 to 2 minutes at idle on the kickstand before checking oil level. Screw cap all the in to check level.

Primary 1 quart, drain plug torque 36 to 60 inch pounds (3 to 5 foot pounds). Primary cover reuse and lube O-Ring mating surface torque 84 to 108 inch pounds (7 to 9 foot pounds). You can use foil like in the below photo as a funnel.

Transmission 1 quart. Drain plug torque 168 to 252 inch pounds (14 to 21 foot pounds). Dip stick 25 to 75 inch pounds (2 to 6 foot pounds)

No thread locking used, I use Teflon thread sealant on the drain plugs, transmission dip stick, and the primary cover screws.

Okay. That's a lot of good information. I just found service manual (pdf) on ebay, so I'll find all the further information there.
Best regards! Thanks everyone!

 

Depending on what oil you have available... you can use the same oil in all three applications. However, if you have some access to different oils, you can use the same oil in the engine (dipstick) and primary (derby), and then a good gear oil for the transmission is suggested. Find oils rated for diesel truck applications and you will be fine. Recommend 20/50 for the engine and 75/90 for the transmission.

You might source the oil from Tembo, I don't see any 20w/50 oils, but they have some 10w/50 for superbikes, but since climate there is 'cooler' the 10w/50 might work fine. and also some 75/90 gear oil.

 

Do you have a HD dealer near you? You can just use their synthetic for all 3 holes if you want to keep it simple for yourself.

Yes , change the gaskets. You can buy a kit at HD for all holes for cheap.

 

Buy the hd service manual .....you'll be glad you did

 

I just did! Good book!

 

I have but not close to me. I'm trying to service what I can. The first owner said that he himself changed the oil. He also recommended that he use one oil for the entire engine. I did not ask him about the gaskets, but I will definitely change them. Thank you!
