5D2-4 TRANSFER CASE (TOD)FUNCTION DESCRIPTION
TOD System Select Mode (4H and 4L) 4H is the mode when drive normally of which gear ratio is 1:1 and 4L mode distributes power to front and rear wheels 50:50 of which gear ratio is 2.48:1.
TOD System Function (select 4H mode) TOD system controls clutch mechanism to comply with rotation in front and rear propeller shaft and if its difference exceeds the permissible range, corresponding power is distributed into front wheel through EMC (Electro-MagneticClutch). Hall effect sensor signals speed on front and rear propeller shafts going through with TOD control unit.
Transfercase clutch coil is activated by variable current on exceeding difference of speed in front and rear propeller shafts.
Function of 4L Mode When select 4L mode, EMC is locked to apply maximum torque into front and rear propeller shafts. Shift motor rotates also 4L position by rotation of cam thus propeller shaft torque changes from 1:1 to 2.48:1 by planetarygear set.
Shift Motor It locates backside transfer case, which drives rotary helical cam. When mode select switch changes to 4L, shift fork is on position for 2.48:1 by rotation of helical cam.
Transfer Case
TOD transfer case distributes power into front and rear axle by operation of 4H/4L switch and shift motor. Shifting 4H to 4L, is performed towards reducing HI-LO collar by means for connection HI-LO shift fork with
output shaft in order to join with planetary gear. Torque transmits input shaft then sun gear rotating front planetary
gear. Front planetary gear join with output shaft and drives LO position.

Assembly Procedure Assembly
Before assembly, lubricate all parts with Automatic Transmission Fluid or equivalent.
1. If removed, drive the bearing into the front output case bore.Drive the bearing in staight, making sure it is not cocked in the bore. Install the internal snap ring that retains the bearing to the front case.
2. If removed, install the front yoke to flange seal in the front case bore.
3. If removed, install the yoke to flange seal into the mounting adapter bore.

4. If the input shaft needle bearing and bushing were removed,
install a new bearing and bushing as detailed in the following steps: Press a new needle bearing, then a new bushing in the input shaft as follows:
a. Position the input shaft on Axle Bearing/Seal Plate or equivalent, and Pinion Bearing Cone Replacer as a
spacer.
b. Press a new needle bearing into the end of the input shaft until it seats in the input shaft.
c. Press in a new bushing.
5. The recessed face of the sun gear and the snap ring groove on the bearing outer race should be toward the rear of thetransfer case. The stepped face of the thrust washer shouldface toward the bearing.
Slide the sun gear, thr ust plate and thrust washer into
position on the input shaft. Press the bearing over the input shaft. Install the external snap ring to the input shaft.

12. Install the output shaft and oil pump in the input shaft.Make sure that the internal splines of the ouput shaft
engage the internal splines of the high-low shift collar. Make sure that the oil pump retainer arm and oil filter leg are inthe groove and slot of the front case.
13. Install the magnet in the slot in the front case just above the oil filter leg.
14. Install the front output shaft in the front case.
15. Install the thrust washer on the rear output shaft. Install the chain, drive sprocket and driven sprocket as an assembly over the output shaft. Notice
The driven sprocket (on the front output shaft) must
be installed with the marking REAR facing toward the rear case, if so marked.
Drive sprocket has a bushing pressed into it.
16. Install tone wheel onto the front output shaft. Make sure the spline on the tone wheel engages the spline on thefront output shaft.
17. Install clutch pack assembly onto the rear output shaft. Make sure the spline of the clutch pack engages to the spline of the sprocket.
18. Install snap ring onto the rear output shaft. Start the snap
ring over the spline and use the wave spring to seat the snap ring in the snap ring groove. If the snap ring will notinstall, the thrust washer inside the clutch pack may not
be seated properly. 1 2 Rear Output Shaft

19. Install wave spring, insulator washer and armature. (Threeoffset slots must align with housing to be installed) NoticeThree slots on the thrust washer must be aligned with the three tabs on the clutch pack housing.
20. Install apply cam onto the rear output shaft, install three balls into the apply cam, install cam and coil housing assembly onto rear output shaft. Install thrust bearing assembly onto output shaft.
21. If removed, drive the front output shaft ball bearing into
the rear cover bore with Front Shaft Needle Bearing Replacer and Driver Handle.
22. If removed, install the rear output bearing in the rear case bore. Drive the bearing into the rear case bore with OutputShaft Bearing Replacer and Driver Handle. Make sure thatthe bearing is not cocked in the bore. Install the internalsnap ring that retains the bearing to the rear case.
