Advice pLease - BSF S60

[SRV1]

Just wanted to stop by and say thanks for this thread. I received a BSF S60 in pretty good shape but wanted strip it down as it shot fairly sluggish.
I could not for the life of me figure out how to get it apart. After much research, in very little material, I found this thread. My example was in the very same
condition. I could take out the restraining bolt and nothing was happening. The grease had seized up the trigger unit where it could not move.
I used brake cleaner and tightening the spring compressor back and forth until it released.
Cleaned everything, lightly lubed and reassembled.
Great shooting rifle. I need to get it over the chronograph but it seems to be hitting around 700fps.
Thanks to the OP and all who responded for saving another classic.

Well done Mr Gray, have fun with the BSF......

One of my two 55s has become unsafe to use in the last few years because while it will cock and ultimately fire, the trigger does not release reliably and sometimes needs 20+lbs of pressure to disengage. Think two fingers and “am I going to the gunsmith with a cocked gun to fix?”. It’s on my long list of things to sort out.

It appears that the old lubes used by BSF turn to glue over time. Maybe use of grease where they should have used oil?

I rebuilt and restored an S70 a few years ago.
The grease had turned yeallow and hard.
It was that solid, that even with the maispring free to push the end block out, it remained in place due to the hard grease. I ended up melting the grease with a torch.

The trigger components were similarly caked in the hard yellow stuff and it took a couple of days soaking in in solvent to thoroughly get rid of it all.

Its not particular to BSF. An old TX I serviced some years ago had the same congealed stuff in the CD trigger unit.

Just Pat is fine.
Again thank you for following through with your posts and helping a fellow air gunner from across the pond.

Looking around the site here I'm so jealous of the many fine air rifles you guys have available. We may have some slight advantage with no restrictions on power but your heritage guns are beautiful to me.
Also the power thing probably hurts more than helps as the most readily available guns are so oversprung as to probably ruin the experience for newcomers to the sport.
