Installation

1. Install oil filter adapter with instructions provided in Jeggs® box.
2. Remove oil filter and set aside. Install oil filter adapter instructions provided with adapter.
   
   NOTE: Make sure to throughly clean the area where the rubber 'O' ring of the oil filter adapter meets the oil filter mounting flange. That area must be oil and dirt free.
   Move the clutch cable. Cut the wire tie that holds the clutch cable to the frame (Illustration 1). Rotate the cable to the outboard side of the fream down tube, do this to make the installation of the cooler cover easier and makes room for the cooler core installation (Illustration 2).
   
   
3. Install the voltage regulator in the new position using the hardware provided (Illustration 3). If you have a chrome voltage regulator cover, refer to Step 4 for proper install. OPTIONAL: By removing 1/4" of the 2 voltage regulator mounting studs will make this part of the install much easier.
   
4. If you have a chrome voltage regulator cover, remove 1/4" of the right side stud. This is so you can get your fingers in to put the nut back on (Illustration 3).
5. Attach the oil lines to the oil cooler as shown in Illustration 4. Short hose on bottom cooler hose fitting, long hose on the top hose fitting (Illustration 4). Position hose clamps, then tighten. Rotate upper hose fitting down. This will make installing the oil filter easier later.
   
6. Attach the pre-assembled cooler to the frame cross member as shown in Illustration 5, using the (2) 10-24x1” allen bolts, spacers, washers and nylock nuts provided. Slide the hose clamps over the ends of the oil lines. Connect the oil lines to the oil filter adapter (Illustration 7). Bolt up the bottom of the cover (Illustration 3). D not forget the blue (medium strength) loctite.
   
   NOTE: Rotate hose clamps so they will not interfere with the oil filter install later, and make sure they are tight.

9. Attach the large black wire from the thermal switch to chassis ground as indicated in Illustration 6. Route the large red wire along the right side of the frame to the break light pressure switch, locate the orange/ white wire (12 volt supply to switch) remove it. Cut red fan wire to length, then crimp on the piggy back spade connector provided.
   
   NOTE: Secure the red wire with care using wire ties to the frame. Broken, bad connection, or shorted wire can cause the fan to malfunction or blow the circuit fuse (no tail light).
10. Double check that all nuts, bolts, screws and clamps are tight and the are awhere the oil filter goes is oil free. Install a new oil filter or the well drained filter that was removed in Step 1. Check oil level level, install your oil temperature indicator (dip stick or dash mount). Start your motor, check for oil leaks. Let the oil temperature reach 160°F and check for leaks again. Drive for one mile, then check for leaks again and observe your oil temperature.
