cool, steve has my number if you need it.

So are all Jackaroo 4jg2's gear driven Cam & fuel pumps?
Will a 4JB1T Timming Gear setup bolt to a 4JG2?

If you changed over to a Belt setup, Do you have the Gear setup for Sale?

Hi MUVIT


I believe that all Jackaroo's sold in Oz with the 3.1 were gear drive.

I am not sure if the 4JB1 is the same block as the 4JG2. the pump looks the same if you have a part number of the pump from a 4 JB1 I can confirm from the pump I have.

I was going to change out the belt set up of the EFI unit with my old gear set up of the old block, but got a belt pump so stayed with the belt. All I can 100% say is the 4jG2 block are the same. Gear and belt version.

I kept the pump not the gears and cover unfortunatly.
