Replace balance shaft chain tensioner w/o pulling motor?

Iím in the middle of replacing the timing chains on my í98 4.0L SOHC 4x4 Explorer. I was going to ignore the balance shaft chain but a piece of the broken jackshaft chain tensioner broke the balance shaft chain tensioner too. Now I have to pull the upper pan/ladder frame. Of course, the manual says I have to pull the motor to remove the upper pan/ladder frame on a 4x4 but I have heard there may be a way around this.<o></o>

Has anybody figured out how to avoid pulling the motor and still be able to replace the balance shaft chain tensioner?

I asked about the balance shaft chain. Not the camshaft chain...

The balance shaft chain is on the front of the 4.0L SOHC motor used in 4WD applications. The 4.0L SOHC used in 2WD Explorers does not have a balance shaft chain.

As far as I know the balance shaft is used on the stick shift only?

No. 4WD vs. 2WD is the determining factor, not automatic vs. manual transmission or transfer case. 4WD motor has the balance shaft and 2WD does not.

Has anybody done it without removing engine ? Maybe drop the pan just enough ? Slide new parts on old bracket ?

I have heard that the tensioner for the balance shaft can be finageled in without taking engine out, but I wouldn't risk it. Some just cut the chain off and roll on without the balance shaft spinning at all. Also, I have the engine from a 2wd explorer in my 04 Mounty and it has a balance shaft. Our 2wd 2010 Mountaineer also has the balance shaft. It is a bit more than just a 2wd/4wd thing. Although I am not certain what criteria they used to determine what gets one and what doesn't.

What is the purpose of the balance shaft chain? what does it do? My wifes 2008 Explorer with automatic 4wd has a noise that sounds like a chain rattling only between the rpms of 2500-3000. It has the V-6 4.0l engine and just turned 106,000 miles.

It appears the bolts holding the tensioner are vertical which, are only accessible with the pan removed.

Here's the only article I could find which, might be helpful...
Balance Shaft Timing Procedure | Ford Explorer and Ranger Forums - Serious Explorations

Hope this helps!




For the curious, this here's where the balance shaft is located...



And the tensioner/balance shaft mounting bolts...



The entire balance shaft assembly...
