bought a used 08 FLHT this summer, man what a great bike, only had 1350 miles on it when I put it on the interstate bringin it home. anyway, the initial oil change had been done by the previous owner/dealer. now it's my turn. I don't have a prob with the oil change, but want to be sure about the primary... new to Harleys. I went to the website area about oil, but got 404 errors.

is that webpage busted ? does anyone have some good step by steps ?

thnx

I change my primary oil at the end of every season in late November. You will get a ton of suggestions on what to use as a primary oil. Just remember that the oil that you do use is not for lubrication. It is for cooling purposes. That said I use Castrol GTX 10/40. There is a drain plug underneath the derby cover for draining the oil. You can refill it thru the primary chain inspection cover towards the front of the primary casing. The best investment you can make and you will hear from just about eveyone on this forum, is to get your hands on a service manual.

 

Hmm, that's not where the primary drain screw is on my '08 EGC.

 

Could I haver erred and that a change has been made since '06?

 

Plug on the 08 is underneath totally, same size as trans and engine drain plug. In the attached pic, from the inside I circled it in red. Pull plug and drain, change o-ring on plug, fill through derby cover with bike upright. Takes 38oz thereabouts.

 

This oil is motorcycle oil. Not just for the motor or one purpose, but made for all three purposes. Motor, primary, and trans.

I stand corrected.

 

Hi DK, welcome to Harleys and HDF from the UK. Oils are one of the most frequent topics on here, along with tyres, so take time for a browse around here. There is plenty of advise available and a confusing variety of answers! But start by buying yourself a factory workshop manual. If all else fails, or you can't decide which advise to follow, do what it says in the book! That will also tell you where your drain plugs are....

The bike is probably under dealer's warranty? What support or service package does it come with? You may not need to do anything with your bike for a while yet. Ask them before doing unnecessary work.

 

Don't over torque the torks head bolts on the derby cover when re-installing, you will appreciate it come next oil change. By the way I use Amsoil 20W-50 in the primary and engine.

 

i use synthetic ATF as many indies do. the ATF is formulated for clutches. the ATF lubricates the chain and pulls heat away from the clutch basket too.
