Right trigger shifter can't shift to lowest gear, 8 speed cassette with Tourney setup
Wanted to verify and see if Tourney derailleur could work if I swap it onto a bike that had a working 3x8 setup.
I had just put it on and haven't had time to do a thorough troubleshoot before I had to go to sleep.
The trigger shifter cannot be pushed to the easiest gear, I tried to push it but it won't click to 1.
Is this too much tension or to little tension? Don't think this is about the derailleur adjuster screws. Will need to come back and troubleshoot it further.
To confirm, Tourney derailleur can work on 8 speed, right?

What model Tourney? There are quite a few versions of Tourney since they came out in 1971. Are your shifters indexed or friction?

Won't be able to check the bike, quick search of the bike it came from and there's only a small image of it available because the original site had deleted it. This particular tourney model had come with a red gear and silver gear covers
I think it might be this derailleur, the shape and color looks really similar, but I can't recall if it says SIS index on it.

Best to go to the PARK Tool site & start from the beginning.

Just a wild guess here: It's not adjusted correctly. I know it sounds crazy but I stayed at a Holiday Inn Express once.

New derailleur? Do you know how to adjust limit screws? Factory settings usually don't allow you to shift onto the biggest cog lest you shift into the spokes

- Disconnect the cable. Hand-shift the derailleur across the cassette/freewheel to see if it reaches all cogs. Adjust limit screws accordingly.
- Pulling on the cable with one hand, operate the shifter with the other. The number of clicks should equal the number of speeds minus 1. Make sure the shifter pulls or releases cable with each shift.
- Examine the cable and housing sections for damage, wear, and corrosion. Replace accordingly
- Shift to highest cog. Retract cable tensioners. Fasten cable to derailleur.
- Adjust cable tension for correct indexing using the tensioners.

It does look like it's a limit screw issue. It can shift up to 1st gear now but it still takes quite a push to push up to it.
