I have a 1998 ford explorer xlt 4.0l v6 sohc 4x4 with a broken jackshaft tensioner. The timming jumped. How do I reset the timming?
Ford explorer xlt 4x v6 4L sohcAlready Tried: looking for marking on the jackshaft sprocket.
The jack shaft tensioner is on the LH head?
Reply to lamontgomery's Post: yes the jack shft tensioner on the lh head.
Have you had field service action 00M12 performed on your Explorer yet?
No. I am in the process of changing the timing chain, sprockets and tensioners myself. the explorer's tensioner fell apart insde the motor so the timing has slipped. How do i get the engin back in timing?
If the timing chain cartridge fell apart, there is a field service action you should read, 01M01. Please hold on, I'm getting the info together for you.

CAMSHAFT CASSETTE REPLACEMENT
NOTE: The LH camshaft roller followers were removed previously if a cylinder leakage test was performed.
CAUTION:You must retime the LH and RH camshafts when either camshaft is disturbed.
CAUTION:When cleaning sealing surfaces, be sure to cover the opening to the oil pan area with clean shop cloths to ensure that no gasket material falls into the oil pan area.
The following camshaft timing procedure must be read thoroughly and performed exactly as written. The procedure includes information that has been updated from Workshop Manual. Do NOT follow Workshop Manual procedures for cam timing on this engine.
OIL PUMP PICKUP TUBE REPLACEMENT
NOTE: The purpose of this procedure is to remove as much of the broken guide material from the crankcase as possible. This procedure is to be followed only if the camshaft cassette was found to be broken-up into small pieces.

There are no cam key ways or timing marks on these engines, you must use the special tools to re time them. This first time I did the job took 3 days with all the special tools. These engines always had problems with the LH timing chain. The newer engines seem to have this weakness corrected.
