SHOE 3P5956 - Caterpillar

Illustration 8 g01047996Note: It is necessary to install Tooling (C) on the camshaft. Tooling (C) will support the rear of the camshaft as the camshaft is moved out of the cylinder head and into Tooling (B). Align camshaft (8) with the bore of Tooling (B). Tighten the bolts that hold Tooling (B) to front housing (7).
Move camshaft (8) forward and install one Tooling (C) in the end of the camshaft. Again, move the camshaft forward and install remaining Tooling (C) into the back of first Tooling (C). Note: Avoid lifting the camshaft with Tooling (D). The camshaft should rest on Tooling (A). Lifting of the camshaft can cause misalignment as the camshaft is removed, resulting in damage to the camshaft bearings.
Use Tooling (D) to move camshaft (8) toward the front of the engine. Reposition Tooling (D), as needed.
Carefully slide the camshaft to the front of the engine for removal. Use two technicians to remove the camshaft. Keep the camshaft level while the camshaft is being removed from the cylinder head. The weight of the camshaft is approximately 39 kg (86 lb). Note: Rotate the camshaft during removal. This will prevent the camshaft from binding in the camshaft bearings.
Remove Tooling (C) from the camshaft.
Remove Tooling (B) from front housing (7).
Remove Tooling (A) from the cylinder head. Installation Procedure
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Do not turn the crankshaft or the camshaft while the camshaft gear is removed. If the front gear group is not correctly timed during installation, interference can occur between the pistons and the valves, resulting in damage to the engine.
Care must be used when removing or installing the camshaft. Do not damage the finshed surfaces of the camshaft or the camshaft bearings.
Ensure that the camshaft and camshaft bearings are thoroughly clean. Lubricate the camshaft lobes with a 50/50 mixture of Tooling (F) and clean engine oil. Apply a thin coat of clean engine oil on the camshaft bearings.

Install Tooling (A) on the cylinder head at Location (Y).
Illustration 10 g01056901
Install Tooling (B) on front housing (7). Do not tighten the bolts that hold Tooling (B) to front housing (7) at this time.
Use Tooling (E) to align Tooling (B) with the camshaft bearings. Tighten the bolts that hold Tooling (B) to front housing (7). Remove Tooling (E). Note: Tooling (E) should move freely from the bore of Tooling (B).
Illustration 11 g01047961
Install Tooling (C) on the rear of the camshaft.
Use two technicians to install the camshaft. Use Tooling (D) to assist in aligning camshaft (8) with the camshaft bearings. Carefully slide the camshaft into the cylinder head from the front of the engine. Keep the camshaft level while the camshaft is being installed in the cylinder head. The weight of the camshaft is approximately 39 kg (86 lb). Note: Rotate the camshaft during installation. This will prevent the camshaft from binding in the camshaft bearings.
Remove Tooling (C) and finish installing camshaft (8) in the bore. Note: Tooling (C) must be removed before the camshaft
