Installation Of Ether Starting Aid (Earlier Machines)
When a 1W162 Direct Injection Engine is installed as a replacement for a precombustion chamber engine used in an earlier machine, an ether starting aid must also be installed on the machine. The ether starting aid groups are as follows: 5G594 Ether Starting Aid Group - 910 Machines; 5G595 Ether Starting Aid Group - D3 and 931 Machines. Use the procedure that follows, according to machine model, for information needed to install the ether aid group. Disconnect the battery at the battery terminals.5G594 Ether Starting Aid Group - 910 Machines
(1) On the right side of the machine (inlet manifold side of the engine) drill two .406" Ø (10.3 Ø) holes (A) in the radiator guard (1) according to the dimensions shown. (2) Drill a .656" Ø (16.7 Ø) hole (B) in dash (2) according to the dimensions shown. Location (C) is the location of the start switch.
Be careful not to damage other components under the dash when hole (B) is drilled.
5G595 Ether Starting Aid Group - D3, 931 Machines
(1) On the left side of the engine (inlet manifold side) drill two .406" Ø (10.3 Ø) holes (A) in the radiator guard (1), according to the dimensions shown. (2) Drill a .656" Ø (16.7 Ø) hole (B) in dash (2) according to the dimensions shown. Location (C) is the location of the start switch.
Be careful not to damage other components under the dash when hole (B) is drilled.
D3, 910 and 931
(1) Use two S509 Bolts with 5P4116 Washers to fasten 5G657 Plate (1) to the inside of the radiator guard, in the holes drilled on either page 3 or 4.(2) Install 5P6315 Elbow (2) in 6N7673 Valve Assembly (3). Use 1C569 Bolts with 4B3849 Washers to fasten 6N7673 Valve Assembly (3) and 7N2059 Clamp (4) to plate (1). Use a 5P6314 Sleeve and 5P6313 Nut to connect 5G659 Tube (5) to elbow (2).(3) Remove the plug from the top of air inlet pipe (6) and install 6N7672 Atomizer (7) so the orifice is down (toward the manifold). Connect 7N140 Tube Assembly (8) and 5G660 Tube (9) to tube (5) and atomizer (7) as shown. Put a 3D5102 Grommet on tube (9) and use 8M2772 Clip (10) with an existing valve cover bolt for support of the tube. Tighten the bolt according to valve cover bolt specifications.(4) Remove plug (11) from the heater hose opening on the top left side of the engine timing gear housing (12). Install 6N5899 Switch (13) in the hole for plug (11). Connect 5G663 Wire (14) to switch (13) and one of the wires on valve assembly (3) as shown.(5) For D3 and 931 Machines, connect one end of 5G689 Wire Assembly (15) to the other wire from valve assembly (3). Use the clips that hold wiring harness (16) to fasten wire assembly (15) as shown, and pull the loose end of wire assembly (15) to the start switch. Do not connect wire assembly (15) to the start switch at this time. For 910 Machines, use 161.5" (41 dm) of 5P629 Wire, one 2L8076 Terminal and one 6K1828 Connector to make a wire assembly (15). (6) For all machines, install 3F1006 Switch (17) in the .656" Ø (16.7 Ø) hole that was drilled in the dash. For all earlier D3 and 931 Machines, and for 910 Machines, 80U1-80U3666, remove the 6S4355 Heat-Start Switch and install 6N8941 Start Switch (18). Put electrical tape on the end of the glow plug wire.(7) Connect 6S9586 Wire Assembly (19) to switch (17) and to the accessory (AC) connection on start switch (18). Connect wire (15), from 6N7673 Valve Assembly (3), to the other connection on switch (17) as shown.(8) Install the ether cylinder assembly and fasten it in position with the 7N2059 Clamp (4) that was installed in step 2.(9) Install a 6S9542 Instruction Film in the location that follows: D3, 931 - Install on the dash above switch (17); 910 - Install on the dash at the right side of switch (17).Installation Of 1W162 Engine Arrangement In 910 Machines As Replacement For: (4N303 Engine Arrangement - 80U1-80U6734), (7N3700 Engine Arrangement - 80U6735-up), (7N9433 Or 1W161 Engine Arrangement - 40Y), (7N9437 Or 1W163 Engine Arrangement - 41Y)
Before installation of the 1W162 Engine Arrangement as a replacement for any of the engine arrangements given above, some changes must be made to the new engine arrangement. See the information that follows. After engine installation is complete, adjust the fuel setting according to the dimension given in the FUEL SETTING INFORMATION. See the Service Manual for engine installation procedure. Machines with the 4N303 Engine Arrangement must have an ether starting aid group. See the information given in this instruction for installation procedure.Oil Filler Tube
