Timken Conversion 03 Dyna : V-Twin Forum: Harley Davidson Forums

Hello,

Since I only have my 03 service manual at this time,I was hoping someone could chime in on the proper orientation of the inner timken bearing (crank side). I know the 3/4" roller bearing sleeve needs to be removed from the crank, but what about the washer behind the sleeve? Does this stay or get removed when the timken bearing gets pressed on?

I will have a 2002 or down manual available before reassembly begins.

Thanks in advance.

I don't think the 1999-2002 books will do you much good in regard to the Timken, because the 1999-2002 engines actually have the Timken stock.

I was hoping it would atleast show the correct procedure for setting up the crankshaft endplay. Just bought a 2000 dyna service manual off Ebay for $30 bucks shipped.

The earlier SM will show you how to setup the Timken bearing and crankshaft endplay. The insert makes it the same as the older cases.

Hey guys,
Newbie here - interesting post.
I'm in the process of buying all the relevant items to stroke my 95cu in to a 103 cu in.
Is it really necessary to fit the Timken bearing?
I know it's a lot better and all that.
How big of a task is it to actually install it and fit everything etc?
Any more info' and/or help is greatly appreciated.
Thanks.

I had a qualified shop take care of the Timken upgrade for me since it requires special tooling. I just provided them the bare case. The engine does need to be fully disassembled for this also.

Depends on the amount of torque and how you ride but if I was changing the crank I would definately do it just for the insurance along with pluging and welding the new crank. We always recommend it at 120 torque.

I was going to get the crank plugged and welded.
What's involved with the timken bearing - just taking one side of the engine casing off and having the sleeve installed?

**KingofCubes** · 10-09-2008, 01:59 PM

Correct, Removing the flywheel assembly from the left case half and installing the bearing insert and bearing. Either machining the outer seal spacer down or replacing it with the shorter 01 unit.

If it were me I would also have the cases bored while it was in the machine shop and go bigger than a 103 but that just me.

How many Timken tapered bearings are there - just one?
There's another post similar to this and people have mentioned timken bearings (plural).

There are two. Just picture a car wheel bearing. There is a inner and outer bearing on the primary side of the engine.
