Dieseling Tx200Hc?

[A1WOC 212]

My .22 TX200 is running very smooth; however, since I fettled and re-greasing a few weeks ago, I have been getting a whiff of oil when I open the breech to insert a pellet. Today I have also noticed a little smoke coming from the breech when opened up after firing, and also a 10% increase in ft/ps on the chrono. Being new to springers, I guess this is a mild form of dieseling. As I have only put around 300 pellets through it since the re-grease, I wondered if it would bed in with a few more pellets, or should I strip it down and be a little more sparing with the grease?

You may need to strip it mate and just clean off any excess. You could end up burning the piston seal and causing damage.

as mawders said mate, youve maybe applied a little too much grease and its getting forced forward and in fron tof the piston seal.

Thanks Phil and you too Darryl. I’m going to strip it down tonight and give it a thorough clean, and reassemble paying particular attention to where I grease.

Just stripped it down, cleaned out the compression tube and grease that had migrated forward of the piston seal, and re-assembled. No smell, no smoke and a substantial drop in power. I must admit it had I worried, when it was chronoed earlier it measured an average 584 ft/s (12.12ftlb) with 16g pellets over a 20 shot string. It now measures 495ft/s; plenty of scope to bed in again without being excessively high.

Thanks for your help.

Yes, and I can take the blame.

didnt mean it like that mate.

 

when i first stripped degreased and relubed my 97 put it back together, i used plenty of grease . after another 1000 shots i took it apart again, although it never dieselled once there was quite a lot of grease that had slipped infront of the seal, totally my fault, although it caused no damage whatsoever.

like they say, less is more eyy

Sorry Skot, I wasn’t having a dig at you; the emoticon was for me putting too much grease on the piston, when I did it a few weeks ago.

I’m back on course again after the weekend adjustment and a further 200 pellets through the barrel. Ragged one hole groups at 25m (10mm edge to edge) with a ten shot string and averaging 564ft/s (11.3ft/lb) on the bench chronograph.

Happy to have it sorted thanks to advice on here.

Thanks and regards, Steve.
