V Roller Replacement

Tools Required:

•	Standard Allen Pack

Routine:

1)	Loosen eccentric rollers so you have more room to work

2)	Remove “V” rollers carefully so the “V” rail edge doesn’t get damaged

3)	Adjustable / eccentric wheels should be the lower wheels if track is horizontal. If track is vertical, just be sure eccentric wheels are both on the same side and on the side where they can be adjusted the easiest

4)	Check to make sure that the “V” rail edge is clean and not damaged or bent

5)	Wheel installation:

a)	Install and fully tighten fixed wheels

b)	Install and snug adjustable wheels tight enough so that they are flush with mount but loose enough so that eccentric wheels can still be turned.

c)	Tighten by turning clock wise until wheel just makes contact with the track

d)	Tighten the nut fully and then check wheel tension against track. Always check after tightening nut because wheels normally will tighten slightly more after nut is tightened

With correct tension, you should be able to spin wheel by hand or very easily with a channel lock. Wheels need to contact both sides of rail. If both sides of all wheels are not contacting rail and wheels are at the correct tension then there is a problem with the assembly, such as it is not square or it may be bent.
