LS front timing cover alignment and seal installer, LS1 LS2 LS3 LS6 LQ4 LQ9

LS front timing cover alignment and seal installation tool

This single tool is listed for front timing cover alignment and front crankshaft seal installation on LS1, LS2, LS3, LS6, LQ4 and LQ9 engines. It has a hollow stepped body, a wide flange and a relief notch at the inner opening. The supplied tool is aluminum with a black anodized finish.

Two tasks at the front of the engine

Cover alignment centers the timing cover opening around the crankshaft before the cover is finally secured. Front seal installation is the separate task of seating the matching crankshaft seal in the cover. This tool is listed for both tasks; the contact surfaces and tool position must suit the operation being performed.

Confirm the engine code and the actual timing cover, crankshaft snout and seal dimensions before ordering. Check modified engines and aftermarket covers individually. The listed engine names do not establish compatibility with every replacement cover or seal arrangement.

Check the procedure for your cover and seal

Verify whether the alignment procedure calls for the seal to be fitted or removed, and confirm that the inner notch clears the crankshaft key where present. Tool height, notch dimensions and dimensional tolerances are not specified.

Use the service instructions for the actual engine, cover and seal to determine tool orientation, seal seating depth and fastener torque. Oil seals, cover gaskets, fasteners and driving tools are supplied separately. The engine and cover in the application photographs illustrate the work area.
