End connectors for VVSS tracks
|The track link pins were
connected by means of end connectors which were held in place by a bevelled
wedge nut. Because of this slight bevel the track links were forced to
curl inward. The end connectors were made of cast steel with integral guide
There were at least three standard end connector types. They come in two basic shapes, one with a narrow guide horn (for 1-1/8" and 1-1/4" diameter pins) and one with a wide guide horn (1-1/4" diameter pins).
First type standard end connector: 1-1/8" diameter holes, large flats, only fits T41 and WE210 tracks.
|Second type: 1-1/4" holes, small flats, most common type.|
|Third type: 1-1/4" holes, small flats, much wider guide horn.|
The official nomenclature in the Standard Nomenclature List for the M4A3 76mm (ORD 9 SNL G-205) from the 1950's lists the actual official US Army name of the part in question is:
I suspect the various styles were acceptable variations of the part. If you ordered the part 7055614 you might get one any one of the 5 styles.
|At least five extended versions
of the common narrow guide horn end connector for 1-1/4" diameter pins
are known. These extended end connectors or 'duckbills' added some 3.56"
to the width of the track.
Type 1: pressed extension welded to second type standard end connector.
|Type 2: with strengthening ribs, probably one piece.|
|Type 3: rectanglar wedge hole, no "dip", probably two-piece welded assembly.|
|Type 4: oval wegde hole, with dip, one piece.|
|Type 5: oval wedge hole, with dip and web, one piece.|
