TSB SB07-01-S009Issue Date: SEPTEMBER 2007
Information On New In-Vehicle Service Procedure For Removal/Installation Of LLV Or LLR Cylinder Head
This Bulletin Supercedes SB07-01-S002
Affected Vehicles:
2007 Isuzu i-290/i-370 (TI)
Service Information
This bulletin is being revised to specifically cover the 4 cylinder LLV and 5 cylinder LLR engines.
The following new service information outlined in this bulletin will aid technicians in removal and installation of the cylinder head without the removal of the front engine cover. The new service procedure can be done in vehicle with the aid of a new Kent Moore special service tool part number EN-48464 - Lower Timing Gear Tensioner Holding Tool.
IMPORTANT:
If the Lower Timing Gear Tensioner Holding Tool is not wedged correctly, the front cover will have to be removed to reset the timing chain tensioner.
The Lower Timing Gear Tensioner Holding Tool will wedge between the timing chain tensioner and the front cover center bolt. When wedged in place this will allow the camshafts or cylinder head to be serviced or removed without the removal of the front cover to reset the timing chain tensioner.
It is very important to make sure when timing the engine that all of your timing marks align; there is no margin for error. If timed incorrectly damage to the engine may occur or a DTC P0017 may set (PCM uses the crankshaft position (CKP) sensor and the exhaust camshaft position (CMP) sensor information to monitor the correlation between the crankshaft and camshaft positions).
