Timney trigger on R700 - cannot pull the trigger nor move safety handle

[nidm]

hi, folks,

something strange happened to me.

I have this Timney trigger on remington700 for a couple months, with roughly 300 rounds. Yesterday starting as normal, and after a dozen round, suddenly, I cannot pull the trigger and cannot switch on/off the safety

the trigger is the same as shown here Timney Triggers Remington 700 Calvin Elite Stage-2

I took out the stock, and video tape the problem on youtube: https://www.youtube.com/watch?v=bYI8CXUijF0

the above video has the bolt in, the same thing occur after taking out the bolt.

Your kindly suggestion is truly appreciated.

Let them check it.

Do you still have your stock trigger? Have you adjusted the sear/travel adjustment or left it bone stock? Have you tried to flushing the trigger out with lighter fluid, as sometimes gunk can mess with triggers in general.

If you have tried cleaning it, them send it in.

Is the bolt cocking?
Look at the cocking piece while you slowly close the bolt handle on an empty chamber.
It should stay cocked and not go back into the bolt shroud.
If it goes inside the bolt shroud it's not staying cocked.
Pull the trigger pins and flush it generously with Rosignol lighter fluid.

I think the bolt cocked successfully. attached two photos, one cocked with a brass in chamber, and photo with bolt pulled back. In both situations, I cannot pull the trigger, nor cannot switch safety on/off.

And I did try another remington 700 bolt, the same problem occurs

Pull the firing pin assy out. Inspect.

I had a Timney trigger in my POF-415 years ago. It shiite the bed after barely a hundred rds. I sent it to them, and they sent me a brand new one - no questions asked!

Timney is good people.

I don't see the the gun cocked in the two photos posted.
I see the bolt closed and not cocked and I see the bolt open. My picture shows the bolt closed and cocked.

If you look at your first picture with the bolt closed you will see the cocking piece way down inside the shroud. It should be sticking out the end of the shroud.

Lynn,

you are right that bolt wasn't cocked. it is embarrassing that I thought stay-in-the-bolt-shroud means "cocked"

Pull the two pins and remove the trigger.
Press down on the sear/top bar then pull the trigger like normal.
That top bar should drop 1/16 inch when you pull the trigger.
If you push on it and it drops down it is adjusted wrong or something inside is broken.
Don't be embarrassed about anything as people are viewing these posts and learning from them.

Good piece of diagnosis, Lynn. Nice helping hand.

Timney Calvin Elites fail in the same manner as a Jewel.
They fail with the firing pin down and will not hold the cocking piece to the rear.
Dirt causes the failure.
The fix is to flush them out with lighter fluid and air to get the piece of dirt out of them that caused them to fail.
This well known problem is why I don't recommend Jewel or Calvin Elite or any other 3 lever triggers on guns that get dirty.

Two lever triggers (stock Remington, Timney 510 series etc...) don't fail in this manner and if they DO get dirty, you can simply rake the trigger shoe forward and back to clear the dirt.
You can't fix a 3 lever trigger that way because the 3rd lever is connected to the trigger by a very lightweight spring.
It's the 3rd lever that gets stuck from dirt.

You can't put it on safe because the trigger is not in a set position.
The trigger is failed in the tripped position.
That's why the cocking piece won't stay to the rear either.

thank you, Lynn, Randall and other folks for your kindly suggestions.

I think the issue is quite clear to me now. I will find a time to the cleaning this weekend. If still exists, will give Timney a call

[nidm]

just like to report back.

I flushed and soaked the trigger with lighter fluid, then air to clean it.

However, it didn't solve the problem. So I sent an email to the customer service and received instruction a couple days later. It turnout out that because I adjusted the pull weight to be lighter, the safety locks up when there is not enough spring pressure in the pull weight. So I adjusted it back, the trigger is back to normal now.

What weight did you go to? Mine was set to 1.5 I think out of the box.
