Techdocs.shimano.com is a very good source of installation diagrams and information. Although THIS LINK is not to your precise model (TZ50, not TZ30), this will get you the info you need. Visit the Shimano technical documents address at the beginning of this message to browse all the tech sheets.

Hope this helps,

Can I replace a Shimano RD-TY15 with Shimano Tourney TX?


Main thing with gears is that they have the same number of gears, and that the cage is the same length. Also the RD TY15 has a built in hanger.

The Tourney pictured has a built in hanger (below link) just make sure the replacement does.

I have a RD-TZ30 derailleur, runs great in all gears except the 6th. I have adjusted up and down 5 to 6 time on the adjustment according to the manual. It keeps trying to jump. Im at my wits end. Any...


Perhaps you have a tight link. Is it always the same place on the chain. Can you duplicate the problem in a static setting, say, with the bike suspended so you can 'pedal' it and observe what is happening at the rear?

or the B-screw adjustment could be such that the upper pulley is touching the cassette.

Or the RD may be bent out of alignment with the cassette.

My shimano RD-TZ30 wont pivot to the right position to tighten the chain it is just staying straight


The deraileur should have two screws on the right side (facing you when you look at the derailleur) try making the screws tighter or looser to tune the derailleur.

My Shimano TX-31 is not lined up correctly. When I shift into 7th the chain comes off because the Derailer goes beyond the 7 sprocket. How do I adjust this? It is also causes a clicking sound when in 1...


Take a look at the diagram in this link, see the two screws identified as Number 3. http://techdocs.shimano.com/media/techdocs/content/cycle/EV/bikecomponents/RD/EV-RD-TX31-2753B_v1_m56577569830637983.pdf
You need to adjust both screws, since one adjusts how far in the derailer goes, and the other adjusts how far out it goes. Start with the bike in a mid-gear and turn one of them 1/4 turn. Check the result. Proceed by trial and error. Good luck. If you found this helpful, please vote. Al K

There are two screws that limit how far the derailer travels in both directions. Yours is apparently traveling to far out, and not far enough in. See the diagram at the link below. The two screws are identified by number 3. You will need to adjust both of them. With the chain on an intermediate gear, try turning one of them them 1/4 turn, then check the result. You'll soon get it right. Good luck. If you found this useful, please vote
