Help! timing chain hitting cover?

[T4x4R]

All,

trying to install the serpentine. got all the way down to the explorer timing chain cover, and now my timing chain is hitting the inside not allowing the cover to seat. Theres about 1/8" of a gap.

Anyone run into this? Any solutions?

Did you remove the old fuel pump eccentric from the old cam gear? If not, there's your problem.

It is possible for there to be interference with the gears and chain themselves, but so far that's been a rare occurence and I don't think I've ever heard of it happening with the Explorer cover. But the fuel pump eccentric issue comes up all the time.

Some timing gear bolt heads and washers are too thick to fit under the explorer cover. You can grind down the head of the bolt to get clearance.

As others have stated, probably the bolt, not the chain itself. Only you can confirm what is actually hitting.

There are 2 different gear thicknesses as well. But I believe both will clear the Explorer timing cover.

And as already mentioned, you did remove the fuel pump eccentric? Make sure you leave a large enough washer to at least partially cover the dowel pin. If that falls out there will be a world of hurt going on as you loose the synchronizing between the pistons going up and down and when the valves open and close.
