How to put back a SKS trigger group w/o hand tool, or making the trigger group unlock/lock easier

[DumduminMud]

As the title says.
Did a few removal and now the trigger group can be easily removed, but it is having problem to be put back.
Yes, I can put it back with the help of a hammer, but it is noisy and I clean my gun at night and I don't want to annoy my neighbor.
On those youtube vod you can just see people putting it back with a whack/pressure from a palm
Is there mysterial method/fluid i can use to make this process easier aside from just taking it apart and putting it back on repeatedly (aka breaking it in)

The Main thing is to be sure the Safety is ON, otherwise it will NOT go back properly. And the Hammer Coc*ed, too ! I used to Whack mine back together with my hand, but now I'm a 75-year old wuss and use a Rubber hammer. Tired of getting 'dents' in my wrist. NOT a steel hammer, Not even a brass one. Just a 'medium' Whack with the rubber one does the trick.
Maybe your 'retention Latch' is gummed up with old grease etc ? And the 'nose' of the group needs to be inserted Fully under that 'bar thing'.

K, taking note:
Make sure the safety is ON (ie you can't fire the damn stick)
Hammer Cocked, although should I leave it forward (closed) or backward (open)?
I will probabaly try to whack it back in with my hand and receive the badge of honor (the dings and dents on my wrist), but that will be morning.
(Side note: I did got pinched when trying to take out the cleaning kit from the stock, so technicallyk already already have one mark)
Currently it is done by using a tower covered steel head hammer to whack the whole thing in.
As of old grease; haven't tried to fully submerge it in boiling hot water yet, will try after next range trip when I shot corrosive ammo into it.
Or just whip out about 4 gallons of Ed's Red I just made and go mad max with it.

Work on your grip strength conscript, the rifle needs no tools but you!

I'd suggest 'DumDum' talk to someone who knows what they're doing ! His recent 'answer' is just as confused and mis-guided as the First.

Turn upside down, & step on it, easier {less tilting} if you take the cover & bolt out.

When I get to the point of t-group disassembly ,I just flip upside down compress slightly by pushing down with force on guard so ever so slightly pushes in then hold while compressed use star head screwdriver and push in at the spot/divet and it opens no hammering needed at least for the 6 ive done. I just push that badboy in when time to reassemble (safety on etc.) Use foot if more leverage needed.
