how to install camshaft synchronizer in explorer

The accuracy of a timing light used is gone, the timing is being set by guessing where to rotate the housing, and the shaft(the window opening). I don't like either way, because they rely on locating the housing and the shaft by eye, not an accurate measurement. I have read that procedure before, but it was likely 20 years ago from a shop manual. The red line is he center of the housing cutout. The tooth should be on the drivers side, NOT the pass side like the alignment tool locates it. Here is the way the Explorer cam synchronizer should look once installed at 20 degrees ATDC (or 340 degrees)īlue arrow is pointing to the front of the vehicle. You want the 'sync 720' lite up green while the engine is cranking over/running. Variables > Sensors > Crank position >EPOS sync level. To verify the 'Sync 720' go to this location in the ProM software. Remember that the synchronizerĭO NOT use the alignment tool that comes with the sensor. Located right below the sensor connector. Located in the middle of the large slot in the housing. Install the cam synchronizer so that the trailing edge of the tooth is Rotate the engine so that the crankshaft is at 20 degrees AFTER TDC on 'Using the alignment tool was never the correct procedure. I just want to pass this info along to others since there really does not seem to be any info out there about setting up an Explorer Synchronizer on a Mustang using the ProM EFI. and this is the response i got which totally contradicts what i was originally told twice.

I emailed ProM back to explain the issue i was having and what someone told me to try. I tried it out and sure enough the car fired right up and idled great! I still have some fine tuning to do but headed in the right direction. So after having the non running issue, a member of the corral gave me some info on facebook. Bring the engine to TDC compression stroke and install the synchronizer using the alignment tool.' Acts as if i had a distributor and it was 180 degrees out.Īfter asking ProM twice on how to time the car using the Explorer cam synchronizer, both times I was told me to FOLLOW the directions on installing one in an Explorer. It cranks and fires but runs for 2 seconds and backfires. Got the car all timed and it would not start.
