If you are referring to the top pic- the cords are broken in the track and then they get out of sync as the bars stretch apart and eventual the point on the sprocket will ride on the bar and not in the hole... probably why the the top roller failed. That picture makes it look like it is on the bars, the other side works fine.
I found out that Viqan will send me two new tracks for around $1600-shipping included and I'm waiting on a response from Dominion who the United Rental shop manager says he uses and he likes their product.
I changed the oil today, greased it and found out that I had three broken zirk fittings, one bearing wouldn't take grease as the bearing grease hole didn't align. Fixed and greased..
Anyone found that the threads are a bit different on the zirks? 1/8 pipe thread or metric?
All grease fittings on that machine are going to be British Metric Pipe Taper (BMPT). It goes back to the Coloniel times of the British Empire and it's colonies around the world. Japan, as well as other Asian countries, still us British specs on their machines. BMPT is very close to National Pipe Thread (NPT) that's used in the U.S., but there's just enough difference to be different. Just for the heck of it, call Robin at Rubbertrax (www.rubbertrax.com) and get a price on tracks. Let us know how their price compares.
