If you're talking about the bearing the main drive gear rides in. #8996A? No- pull the pipes, primary, inner bearing race, & trans gearset, the you can remove the MDG, and then , finally, R&R the MDG bearing.

I have an '06 screaming eagle 6-speed transmission with bad main shaft bearing. Am I able to remove and replace that bearing without pulling out the gear set or pulling trap door?

Yes, says the same thing both sides.

is it Laser etched both sides ?

Not sure on how the wages compare here to USA . 

Really now...       

That's the 49 state version with cat exhaust (i try to avoid those limitations )

Contact JE Pistons. Give them the info, including that they were used with Branch heads (year, cu. in. and model). they should be able to give you the info. The sheet should look like this one. These were pistons I designed for turbo-charged Twin Cams when they first came out.

I saw this tool and had to have it. It allows you to jam the rear sprocket and chain to remove sprocket bolts, or the countershaft sprocket nut. Only thing about it is it's aluminum, so you wouldn't want to pound on it with impact tools unless you are holding good tension on the chain to keep it tight.

It works with 520, 525 and 530 chains.

Just some additional info. These are the three parts you would need to retain from your original transmission to put in a 2010 and newer six speed.

2006 to 2009 original part - 35470-06  COUNTERSHAFT ASSEMBLY
2006 to 2009 original part - 35801-06  GEAR, FIFTH INPUT
2006 to 2009 original part - 35201-06  GUIDE HUB, DOG RING

I found 35201-06 at a US HD dealer. The 35801-06 I found at an HD dealer in Wales UK. The 35470-06 countershaft I found a used one in great shape from a crashed 2008 RK. There are none in the USA or Canada.

Your options:
(1) Use a newer transmission, 2010 to 2016 can be used, just these three parts have to be switched over from your transmission or another early model.

(2) Or find a 2008 to 2009 transmission in good shape and just bolt that in.

(3) Install a 2008 or newer mainshaft in your transmission with the correct inner primary race.

(4) Using the transmission as it is, but TIG weld a spot on the edge of the inner primary bearing race to the mainshaft.
