Remove BrakeSaver
Start By:a. remove flywheel (BrakeSaver) 1. Disconnect BrakeSaver lubrication oil line (1) from the fitting in the BrakeSaver housing. 2. Disconnect the oil line from fitting (5).3. Remove two short bolts (2) and two longer bolts (4) that hold manifold (3) to the BrakeSaver housing. Remove manifold (3) from the BrakeSaver control valve.4. Remove the O-ring seals from the manifold. The two longer bolts (4) from the manifold can be used as forcing screws to remove the BrakeSaver from the flywheel housing. 5. Install a 3/8-16 NC Forged Eyebolt in the top of the BrakeSaver housing, and fasten a hoist to it.6. Install Tooling (A) on the BrakeSaver housing and rotor. Tooling (A) holds the BrakeSaver housing and rotor assembly together at removal. This prevents damage to the rotor rings and seals.7. Remove bolts (6) that hold BrakeSaver housing (7) to the flywheel housing.8. Use bolts (4) as forcing screws, and tighten the bolts evenly to remove BrakeSaver housing (7) from the flywheel housing. The weight is 86 kg (190 lb).Install BrakeSaver
1. Install Tooling (A) on the BrakeSaver housing and rotor. Tooling (A) holds the BrakeSaver housing and rotor assembly together at installation. This prevents damage to the rotor rings and seals.2. Install a 3/8-16 NC Forged Eyebolt in the top of the BrakeSaver housing, and fasten a hoist to it.3. Install two 5/8-18 NF Guide Bolts (9) in the crankshaft, as shown. Ensure that dowel (8) is in alignment with the dowel hole in the rotor assembly, and put BrakeSaver housing (7) in position in the flywheel housing.4. Install the three bolts that hold the BrakeSaver housing to the flywheel housing. Remove Tooling (A) and guide pins (9). 5. Connect the oil line to fitting (5).6. Inspect the O-ring seals for damage, and make replacements if needed. Install O-ring seals (10) and (11). Put clean engine oil on the O-ring seals.7. Install manifold (12) into the BrakeSaver control valve, and install the four bolts that hold the manifold to the BrakeSaver housing. 8. Connect BrakeSaver lubrication oil line (1) to the fitting in the BrakeSaver housing.End By:a. install flywheel (BrakeSaver)Disassemble BrakeSaver
