TIPS, RECOMMENDATIONS & INSTRUCTIONS

 

 

Replacing
In most backhoe loaders are mounted teeth screwed. Each tooth includes two plow bolts. Replacement usually involves removing or
cut off the head bolts and remove the rest of the tooth. After blade cleaning, apply new teeth and tighten the new bolts.
Caution! Do not tighten the screws with big force! Just minimal torque is enough. You can also protect against loosening nuts with special agent. During
tightening tooth can not be subjected to stress, because it will crack teeth.
Replacement of Caterpillar type teeth ends
1.Hit several times with a hammer teeth end to remove dirt and to loos fixing.
2.Remove locking pin.
3.Remove teeth end, then clean the adapter from mud and earth.
4.Applie new protective sleeve with protection cap in the adapter hole.
5.Applie new teeth end on the adapter and assmebly new locking pin until it clicks into the groove at pin bushing.
Bofors teeth replace
1 Remove the old teeth protection woth the hammer.
2 Remove the old teeth.
3 Clean the hole in the adapter.
4 Install the new teeth end in the adapter.
5 Secure teeth with new metal-rubber buckle.

Ruberr track measurment

NOTE: For rubber track with a small diameter [1] can replace the original size by increasing the number of cells [2] twice at the same time reducing the
distance between cells, the scale [3] 1 Measure the width of the rubber chain (in mm) – [1] 2 Count the number of chain links – [2] 3 Measure the distance of the chain links (in mm) – from the middle of one link to the middle of the next one – [3]
Sometimes the roller type of the machine is also important. Track selection due to the rollers
- Check the type of rollers used in the chassis of the machine,
- Measure and provide the dimensions D and E from rollers.
- There may be two markings of rubber tracks
W (wide) – wide roller (dimension D)
N (narrow) – a narrow roller (dimension D)

Rubber track replace
Prior to activities related to the replacement of rubber track, turn off the mini excavator and make sure that the machine safety lever is in the
LOCKED position. Replacement of rubber track should be carried out in accordance with the mini excavator owner manual.

1 Lift up the machine so that the rubber tracks are clear of the ground (use for this purpose bucket and blade)
2 Remove the cover for tension mechanism
3 Release the rubber track tension by removing the valve track tensioner [nipples].
4 When the idler move back to end position, remove the old rubber track.
5 Check the wear of the sprocket, rollers and idler. In case of excessive wear those part need to be replace.
6 Assembly new rubber track
7 Tighten the idler tensioner valve and apply grease.
8 Check the rubber track tension – measure the distance from rubber track in the middle of its length to the lower edge of the rollers.

Tension of the rubber track
1 Rubber track must be tensioned by force in accordance with the manufacturer’s recommendation.
2 To verify the track tension set mini excavator in a position that rubber track not touch the ground (leaning mini excavator with a
bucket on one sie and ot the other side with the blade).
3 The rubber track is properly tensioned when the overhang is between 10-20 mm
4 Rubber track tension should be checked every 15-20 hours of excavators work.
5 For new rubber track within the first 15 hours of work 2-3 times track tension neet to be check.
6 In order to avoid impact or contact with a working rubber track,the distance between the excavator body and the rubber track tread should be at least 30mm.
7 Wrong rubber track tension, in both case: too strong or too weak will cause damage of the rubber track.

Basic rules of proper rubber tracks usage
1 It is very important to maintain proper tension of rubber tracks throughout their whole life. Too loose rubber track will fall or jump on the sprocket teeth causing rubber track damage. Too high tension will follow to crack of the rubber track. To avoid this, check the in the user manual recommended tensioning force or ask in Intramex Valuepart Polish for this value.
2 Regularly check the wear of the sprocket, rollers and idler. If your teeth are excessively worn this will cause rubber track crack. Never assembly a new rubber track if the sprocket, idler or rollers are excessively worn.
3 Avoid driving excavator on rocky surfaces, sharp rocks and stubble. Tracks are not recommended for all types of ground.
4 Avoid too long contact with the surface of the rubber track at high temperature (eg, hot bitumen)
5 Avoid driving excavator over rough ground.
6 Avoid sharp turns, to big rotation at the place or turns driveways with a sharp turns.
7 Try to avoid big obstacles that may damage the mini ecavators chassi.
8 Not invading edge of the rubber track on the curbs and other outstanding sharp objects.
9 Avoid climbs and descents from the high curbs.
10 Do not use a mini blade to push.
11 Avoid setting the mini ecavator side on one track.
12 Do not hit with a bucket the rubber track.
13 If you get a rubber track with oil or other petroleum substances immediately clear it.
14 When driving on carrier lorry with excavator use ramp with small angel.
15 If you plan a longer stop of excavator think of a dry, not sunny place to protect rubber tracks from the impact of changing weather conditions.
16 After work, clear the chassi out of the mud, earth, stones. Always clean the tracks track with water after working on the saline ground to keep
it from oxidative stress.
