My third shot of the day resulted in a stuck safety in a fully cocked condition. The safety would not move and the trigger would not work at all. I had to tear down a fully cocked gun. No fun at all. The upper leg of the safety spring broke off and lodged in such a way to bind up the works. A call to Umerex was placed for spring # 123 in the T06 schematic drawing. Costs $8.00 shipped. The whole trigger assembly was $80.00 shipped. Not this time. Luckily I have my older spare 34 .22 for backup plinking while I wait.
D34...out of service.

They all break sometime or another. It is just the way of the world. $8.00 ain't bad for a fix on a nice gun.

the good thing is we can find parts in the states and the bad news is they charge 1.32 in Europe for that spring

Man what a mess you had there. I'll bet that wasn't fun breaking it down from a cocked position. As many pellets as you've put through that 34 without issue, I wouldn't be too upset.....simple fix.

I used my home made spring compression fixture but ran out of travel while still under load. I inserted the pins into the trigger pin hole to hold the spring in place while I removed the pushing hardware. Like messing with a fox trap....yikes. I pulled the trigger assembly from the side and it came free. I wadded up some rags to catch the spring then pulled the pins out. WHACK!! the spring was caught with the rags. No harm done. That little spring leg flexes twice riding over the cross pin for every shot fired. That's a mess of flex cycles over time.

I will agree the TO6 trigger is really good…but….better get a #123 safety spring or two in your inventory. It is a weak link in the assembly. I plan on making it a routine replacement item when doing periodic maintenance. That safety was bound up tight and would not disengage. Major hassle tearing down a cocked gun as you can not remove the cocking link with piston locked in rearward position. Best I can remember is that it broke around 18K shots.
Was there a better way to release the cocked piston?

The replacement spring came in today and I installed it. Gun is back together and shooting great again. I had no choice but to install a new seal, the second RWS one in there was ragged around the skirt. A new Vortek seal replaced it. The Vortek spring I installed a year ago is just as strong as new, so it stayed. I also called Umarex to order two more safety springs and a two pairs of trigger cross pins. They comped me for the broken spring, the $8.00 was all shipping cost. He was surprised to hear I had 18K plus shots on that TO6 equipped D34. To his knowledge I might be the first to find weaknesses in a high mileage TO6 trigger. About $25.00 plus shipping for these replacement items.
Besides the broken safety spring, the two trigger cross pins have significant wear grooves from the hardened slide link that rides over them. I do not think grease lubing them would have helped much. I would not want grease in a trigger assembly to collect dirt and migrate all over inside. I will replace those worn cross pins when the new ones arrive. I like the TO6 trigger but it has flaws as I am finding out. My TO5 trigger equipped old 34 is still perfect with twice the shots fired. I am tempted to let RWS Diana in Germany know about these findings.
When the trapped cocking link got hit with the piston it dinged the front edge of the compression tube and ripped into the wood end stop of my fixture. I had that link wrapped with several layers of duct tape to help slow it down, but it tore like it was not even there. The spring was still under heavy load for the rest of disassembly.

Good job Bob ! I assume then that those pins are a mild (cold roll) steel ? That video was slick. I would probably only use a dry film silicone on trigger pivot points. Maybe those galled pins contributed to that spring breaking ?

I'm glad to hear that you got your spring and have it all back together again. You should let Diana know your observation regarding the T06. Some companies take customer feed back like that and use it for product improvement. You never know....
The trigger cross pins in my 34 have deep grooves worn in them just like yours. I have wondered if or when that will ever pose a problem.
