Operating Instructions

5. Servicing and Maintenance

5.5 Double Disc Axles

The axles on this roller are tensioned by the

main axle through the centre of the rings and

bearings.

Specialist equipment is required for the

disassembly of Double Disc axles. Please

consult your dealer under any circumstances

that require disassembly of these axles.

Maintenance of these rollers is limited to daily

greasing of the bearings to flush out dirt, and

regular inspection to ensure the assemblies

are tight, and scrapers are correctly set. The

axles can be tightened provided the bearing

pillar ‘U’ bolts are loosened to avoid

preloading the bearings as they move

sideways to each other. Ensure the bearing

pillars are re- tightened to the mainframe after

this.

5.6 Wing Pitch

On SL700 Models, the pitch of the wings can

be altered by using the threaded ends of the

wing cylinders. Tightening the will raise the

outer tips of the wings and loosening wil lower

the outer tips.

5.3.2 Bearing Seals

It is important when replacing the labyrinth

type bearing seals in disc hubs that the seal

is fitted the right way round. The chamfered

lip side should be at the outside of the bearing

housing, nearest the disc arm (see Fig. 5.02).

This chamfered lip prevents dirt ingress into

the housing and also allows grease to be

flushed though when greasing.

5.4 Terra-Grip Tine Points

Tine maintenance should be

performed with the machine fully

raised and with all taps closed.

When working under the machine

ensure that the tractor handbrake

is on.

When changing points on Terra-

Grip tines extreme care should be

taken. Wear goggles at all times

when changing tine points.

5.7 Brakes & Wheel Hubs

The brakes should be tested before using for

the first time and after the first laden journey.

Check that the road and parking

brakes operate and release

correctly before using the machine.

Check for hydraulic fluid and air

leaks.

Brake and wheel hub maintenance

and servicing should be carried out

by an authorised Simba dealer.
