DX,REPAIR –19–17FEB99–1/1

Service Tires Safely Explosive separation of a tire and rim parts can cause serious injury or death.

Do not attempt to mount a tire unless you have the proper equipment and experience to perform the job.

Always maintain the correct tire pressure. Do not inflate the tires above the recommended pressure. Never weld or heat a wheel and tire assembly. The heat can cause an increase in air pressure resulting in a tire explosion.

Welding can structurally weaken or deform the wheel.

TS211

Check wheels for low pressure, cuts, bubbles, damaged rims or missing lug bolts and nuts.

–UN–23AUG88

When inflating tires, use a clip-on chuck and extension hose long enough to allow you to stand to one side and NOT in front of or over the tire assembly. Use a safety cage if available.

Safety Information

L124515

When servicing front-wheel drive tractor with the rear wheels supported off the ground and rotating wheels by engine power, always support front wheels in a similar manner. Loss of electrical power or transmission/ hydraulic system pressure will engage the front driving wheels, pulling the rear wheels off the support if front wheels are not raised. Under these conditions, front drive wheels can engage even with switch in disengaged position.

General Repair Information General Safety and Repair Information CAUTION: When performing repair work comply with the following repair information as well as the safety rules given at the beginning of this manual! See "Safety Information" in Group 00.

NOTE: The illustrations show parts and procedure on one axle type, repair procedures however are the same for all axle types.

Before performing service work on front axles, clean them thoroughly.

Specified special tools must be used for service work.

These special tools have the appropriate dimensions and therefore correct positioning is ensured.

Damaged or excessively worn parts must be replaced.

An experienced technician must evaluate whether parts may be re-installed which are subjected to a normal wear process (e.g. roller bearings, thrust plates etc.).

Always replace parts like seals, O-rings, self-locking screws and nuts.

Before re-installation of parts remove all gasket material from sealing surfaces of housings. Remove any burrs etc. using a whetstone.

Take extreme care to avoid that shavings or other foreign material remain in housing.

01 1

Apply clean hydraulic oil to all bearings before installing them.

For heating parts (bearings for example) only appropriate heating devices must be used (oven, hair dryer etc.). Under no circumstances exceed specified temperature limits!

When heated parts have been installed, reseat them after they have cooled down to ensure correct fit.

When re-assembling the front-wheel-drive axles note the torques for hardware and specifications for adjustments.

Unless otherwise specified tighten bolts and nuts to the torques listed in the enclosed charts. See "Front-Wheel-Drive Axles - Torques for Bolts and Nuts" , in this Group.

After repair work has been completed make sure that the front-wheel-drive axle operates correctly.

The following and additional information can be found under "Specifications", Section10, Group 05 of the Repair Technical Manual.

• Capacities, see "Capacities" • Lubricant specifications, see "Front Wheel Drive Axle Oil" • Grease specifications, see "Grease"

Check that lubrication bores or grooves are not restricted.

General Repair Information 01 2

Front-Wheel-Drive Axles - Torques for Bolts and Nuts DO NOT use these values if a different torque value or tightening procedure is given for a specific application.

Torque values listed are for general use only.

The specified torques do not apply to coated nuts and bolts (e.g. phosphate coating).

Use a torque wrench to tighten all bolts and nuts.

Fasteners should be replaced with the same or higher grade. If higher grade fasteners are used, these should only be tightened to the strength of the original.

Make sure fasteners threads are clean and that you properly start thread engagement. This will prevent them from failing when tightening.

Description of Front Wheel Drive

LX1027668–UN–11DEC01

200 3

A—MFWD clutch

B—Universal jointed shaft

When front wheel drive is selected on tractors equipped with front wheel drive, all four wheels are driven simultaneously. This increases the tractor’s pulling power and reduces wheel slip.

Power is transmitted from the transmission to the rear wheels via the final drives. At the same time, power is transmitted from the transmission via front wheel drive clutch (A) to universal jointed shaft (B), which then drives the front wheel drive axle (C) and thus provides power directly to the front wheels.

Front wheel drive is engaged and disengaged by means of a rocker switch. When front wheel drive is engaged, a solenoid valve interrupts the flow of oil to the front wheel drive clutch. Belleville springs

C—FWD axle

compress the disk pack in the front wheel drive clutch and form a connection between the transmission and front wheel drive axle. When front wheel drive is disengaged, oil flows from the solenoid valve to the front wheel drive clutch. The Belleville springs are compressed by the oil pressure and the disk pack is released. There is no longer a connection between the transmission and the front wheel drive axle. Front wheel drive is always engaged when the engine is shut off, as the transmission pump stops pumping oil.

Changing the gear pair or the tire combination enables an overrun of between 1.5 and 4% to be obtained at the front wheel drive axle. This means that the front wheels turn slightly faster than the rear wheels. This improves the tractor’s traction.

A—Axle housing B—Differential

E—Drive shaft

Axle housing Axle housing (A) consists of two or three parts which are flanged together. The ends of the axle housing are shaped like forks, to which the axle knuckle housings (C) are attached.

Knuckle housing Axle knuckle housings (C) provide the connection between the axle housing and the wheel hubs (D). The axle knuckle housings enable the axle to be steered.

Differential Differential (B) is located in the center of the front wheel drive axle. The differential allows the two front wheels to turn at different speeds, e.g. when cornering.

The differential consists of the differential housing, ring gear and drive pinion. The drive pinion transmits power from the universal jointed shaft to the differential.

Located inside the differential housing are the drive bevel gears and compensating bevel gears, together with two disk packs which permit self-locking. The differential is designed to be self-locking. In most cases, this prevents wheel spin when moving off and when the machine is in motion (e.g. due to slippery conditions).

Drive shafts Drive shafts (E) transmit power from the differential to the wheel hubs. The universal joint on each drive shaft compensates for the different locations of the differential and wheel hubs.

Wheel hub with planetary drive

Steering cylinder

The planetary gears in planetary drive (D) are driven by the sun gear shaft located on drive shaft (E). The planetary gears rotate around the stationary hollow ring gear, taking the planetary carrier and wheel hub with them. The planetary drive reduces speed and increases torque.

The steering cylinder (F) is integrated into the axle housing. It consists of a steel sleeve and a piston with a piston rod at both ends. The piston area is the same at either end and the steering system is therefore fully balanced.

Power flow when moving straight ahead When the tractor is travelling straight ahead, the driven ring gear (D), housing (G) with bevel pinions (E), drive bevel gears (B) and drive shafts (A) all turn at the same speed.

Bevel pinions (E) do not rotate around their own axis.

The two driven wheels are driven with equal power and at equal speed.

Power flow when cornering When the tractor is turning a corner, only the driven ring gear and the housing with the bevel pinions rotate at the same speed. As the right wheel - and thus the right drive bevel gear - are stationary, the bevel pinions must idle with the right drive bevel gear. As they do so, they rotate around their own axes. The left drive bevel gear meshes with the rotating bevel pinions. This produces an additional drive for the left drive bevel gear, which normally turns idly with the ring gear when the tractor is moving straight ahead.

G—Housing

As a result, the left drive bevel gear with its associated drive shaft turn twice for every one rotation of the ring gear.

Thus, if the drive wheels have unequal resistance applied to them, the wheel with the least resistance turns faster. As one wheel turns faster, the other turns slower by the same amount.

Operation of Self-Locking Differential

LX003429

200 8

A—Drive bevel gear

B—Disk pack

The self-locking differential improves the driving qualities of the machine when operating on rough and slippery ground. The differential effect may be eliminated completely or only partially. It prevents loss in performance caused by slippage at the drive wheels. Compared with a hand or pedal shift differential, the self-locking differential has the benefit that it limits the load on the wheel drive shafts. A further advantage is that during actual operation, it becomes effective immediately and automatically when needed, without any assistance from the operator.

The locking effect is produced by two multiple disk packs (B) positioned symmetrically in the differential housing. Due to reaction forces generated during the transfer of the drive torque, axial forces are produced on the inclined surfaces of bevel pinions (C). These

C—Bevel pinion

axial forces, generated in the splines during torque transfer, exert pressure on the disk packs via drive bevel gears (A), which can move axially along the drive shafts. Since the externally toothed disks engage with the differential housing and the internally toothed disks mesh with the drive bevel gears, relative movement between the drive shafts and differential housing is made more difficult.

The axial forces effect a load-dependent locking torque in the disk packs which is always in direct proportion to the input torque, i.e. the input torque remains proportional to the output torque with a constant locking effect. The locking effect therefore varies to match the changes in engine torque and torque levels in the various gears.

A—Planetary carrier B—Planetary gear C—Disk pack

D—Brake piston E—Hollow ring gear F—Oil from/to brake valve

G—Spring H—Externally splined disk I—Internally splined disk

Pressure oil (F) flows from brake valve behind front axle brake piston (D) when brake pedals are depressed. Oil pressure forces the brake piston against disk pack (C) thus compressing it. A connection is formed between the externally splined disks (H), which are connected to the stationary hollow ring gear (E) and the internally splined disks (I) which are in connection with the sun gear shaft (K) via disk carrier (J).

J—Disk carrier K—Sun gear shaft

With brake pressure increasing, the force exerted on the disk pack by the brake piston increases as well and the sun gear shaft is braked. The braking effect is transmitted to the front wheels via sun gear shaft, planetary gears (B) and planetary carrier (A).

When the brake pedals are released, oil pressure is decreased and the springs (G) pull the brake pistons to their initial position. Oil returns to the brake valve.

1. Check tire inflation pressures.

2. Mark drive flange of front wheel drive axle (A) and the flange of universal jointed shaft (B) (see arrows).

LX003431

NOTE: Observe correct positive front wheel lead.

Incorrect front wheel lead causes excessive wear of tires and other components.

–UN–08FEB95

Positive front wheel lead: 1.5 to 4%

3. Secure universal jointed shaft with a rope as shown.

CAUTION: With tractor running, stay clear of moving parts.

4. Switch on front wheel drive and drive the tractor slowly forward in the lowest gear until the drive flange of the front wheel drive axle has turned 25 times.

NOTE: When the drive flange has turned 25 times, the universal jointed shaft should have turned 25.5 to 26 times, which represents a positive front wheel lead between 2% and 4%. If positive front wheel lead is not correct, check the tire combination (see Operator’s Manual).
