Does anyone know if it is possible to R&R the hex drive without splitting the case?

For example, locking the cams, removing the intake/exhaust cams, tappets, then remove the oil pump to retrofit?

This guy, I think... ?

Absolutely you can replace this without splitting the cases. You can do it with the engine in the car, but will have to support it so you can remove the rear engine carrier to have good access to the oil pump. Can't remember if you have to take the whole oil pump off or just the cover over the gears.

Thanks for the quick reply. Reason I ask this is because when doing the IMS retrofit I remember reading about the ims tube resting on the oil pump console... and I guess I would be concerned about removing the oil pump cover/console - thereby relieving tension on the ims tube (thereby messing up timing/snapping shafts/etc.)...

I found this thread over on rennlist I think I will post there and ask the person how they did this.

That and I found this on the LN website:

From http://www.lnengineering.com/ims.html

Do you offer an upgraded oil pump drive that goes into the IMS?

Yes, we now offer a heat treated chromoly oil pump hex drive to replace the cheap factory pump drive, which has known to fail, shearing in two, resulting in a catastrophic loss of oil pressure.

The oil pump drive is located off the intermediate shaft on the opposite side that hold the ball bearing and mates to the oil pump console, located on the front of the engine. This part should not be changed with the engine in the car, as the oil pump console must be removed to R&R the oil pump drive.

Thats what I read but I dont think its true I think you can remove the shaft with the engine in the car you just to remove the whole back of the motor to get to it. I will be doing this soon.
