Method for replacing a drive lug of an endless rubber track
An individual replacement drive or guide lug for missing or worn lugs located on an inner circumference of various endless rubber tracks used on multi-surface vehicles. The lug comprises a body and a fastening including a bolt and washer. To install the drive lug properly, an inner surface of the track where the original vulcanized rubber drive lug was located must be prepared. When the original drive lug fails, it leaves an irregular surface and must be ground flat with the inner track belt substrate. The bolts are then secured through the track and the lug so as to removably secure the lug to the inner surface of the track.
1. A method of replacing an existing original equipment manufacture drive lug vulcanized to an endless rubber track having an inner circumference presenting an inner surface of the track and an outer circumference presenting an outer surface of the track, the method comprising the steps of:
obtaining a replacement drive lug configured to be secured to the inner surface of the track,
the drive lug including—
a body having a bottom and a top and at least one opening formed through the body,
wherein said bottom is configured to be secured to the inner surface of the track, and
a fastening element for securing the replacement drive lug to the inner surface of the track;
removing the original equipment manufacture drive lug from the track so as to provide a surface for receiving the replacement drive lug; and
mechanically fastening the replacement drive lug to the track.
2. The method as claimed in claim 1 , wherein the fastening element includes at least one bolt operable to be secured at least partially through the outer surface of the track and the body of the lug.
3. The method as claimed in claim 2 , further including the step of:
indexing placement of the replacement drive lug on the track by marking and forming at least one hole for the bolt on one of the inner surface or outer surface of the track.
4. The method as claimed in claim 3 , further including the steps of:
inserting the bolt into the hole marked and formed in the track; and
aligning the bolt with the opening formed through the body of the lug.
5. The method as claimed in claim 4 , wherein the step of mechanically fastening the replacement drive lug to the track is performed by inserting the bolt generally through the body of the lug via the opening in the lug.
6. The method as claimed in claim 1 , wherein for the step of removing the existing drive lug from the track, the drive lug is removed by grinding the existing drive lug generally even with the inner surface of the track.
7. The method as claimed in claim 3 , further including the step of providing a template for indexing of the replacement drive lug on the inner surface of the track.
8. The method as claimed in claim 2 , wherein the bolt includes a head, and at least part of the head is external to at least one of the body and track.
9. A method of replacing an existing original equipment manufacture drive lug vulcanized to an endless rubber track having an inner circumference presenting an inner surface of the track and an outer circumference presenting an outer surface of the track, the method comprising the steps of:
obtaining a replacement drive lug configured to be secured to the inner surface of the track,
the drive lug including—
a body having a bottom and a top and at least one opening formed through the body,
wherein said bottom is configured to be secured to the inner surface of the track, and
a fastening element including at least one bolt, said fastening element operable to be secured at least partially through the outer surface of the track and the body of the lug;
removing the original equipment manufacture drive lug from the track so as to provide a surface for receiving the replacement drive lug;
forming at least one hole for the bolt on one of the inner surface or outer surface of the track;
inserting the bolt into the hole formed in the track;
aligning the bolt with the opening formed through the body of the lug; and
mechanically fastening the replacement drive lug to the track by inserting the bolt generally through the body of the lug via the opening in the lug.
10. The method as claimed in claim 9 , wherein for the step of removing the existing drive lug from the track, the drive lug is removed by grinding the existing drive lug generally even with the inner surface of the track.
11. The method as claimed in claim 9 , further including the step of providing a template for indexing of the replacement drive lug on the inner surface of the track.
12. The method as claimed in claim 11 , wherein the bolt includes a head, and at least part of the head is external to at least one of the body and track.
