Help-cat 3406b Fuel Inj-pump Removal From Engine Front Drve Cover

Hello, I Am New To This Site And It Seems Awesome Especially If I Can Get Someone To Tip Me On How To Remove The Fuel Transfer/injector Pump Out Of The Back Of The Engine Drive Cover. I Removed All Accessories. Then All Mounting Bolts, Removed Advanced Timing Mechanizm On The Front Of The Drive Cover......now It Seems That The Pump Drive Gear Is Splined On To The Pump Or Pressed? Im Redoing Oil Seals From The Pump To The Block (o-rings) And The Front Drive Gear Is Halting Me.....im Assuming I Gotta Time The #1 Cyl At Tdc And Get A Timing Tool From Cat For The Pump? On My Way To Cat To See What They Tell Me.....hopefully They Do.....its Friday. How Do Properly Do This...help Somebody! Thanks

Did you get the bolts that attach to the side of the block? As far as timing, rotate engine to #1 TDC compression and on the middle of the pump there should be a little 9/16 bolt, remove that and you should see a slot, when its timed right that slot should be in the center, there is a tool from cat that fits in there i believe to hold it.

U dont need a tool from cat a 3/8 bolt works great. when u have the pump off remove the plug, like the other guy told ya. and use a bolt copple inches long and turn the pump over till the bolt dropes down and then your at #1 on the pump. I don't know if u know, that there is a small plug on the front of the bellhousing on the right side remove that plug inscert a 3-4in 3/8 bolt and turn over the engine, hold pressure on the bolt and it will slide into a hole in the flywheel when it does, it's at tdc 1 or 6 check your rocker arms to see if intake and exhaust on #1 in loose, then your at tdc #1
