Folks,
Further to my blow back failure post I now know I need a new "bulb seal".
Does anyone have a dead SA177 they are taking parts off?
It is located on the inside back end of the slide and looks like the picture attached. I beleive it is usually one part and mine fracture into 2....
I'd love to rescue the blow back rather than just convert it to nonBB.
I have feelers out to my usual parts sources but thought I would check this pool.
Any help is appreciate. Thanks.

Hi Plinkercases!

It seems that you may have some problem getting the parts. I talked to a guy at our Army Suplus Store who is an Umarex rep and he told me that the SA 177 is not supported by parts (it seems right because I was not able to dig an exploded diagram on the internet).

He told me that he has access to parts and can crossmatch with parts of other models if he has the spec of the seals (measurements).

His name is Kyle and was at work this afternoon.

This is the link to the contact page, the phone number is there:

http://sasonline.ca/index.php?option=co ... &Itemid=89

You may have to send him the broken part for him to match them, so it might be better if you talk to him and make some arrangement.

If you prefer to e-mail him, I have his address. You can PM me.

Hi R-Gun Pete,
Great (or obsessed minds) think alike.
I spoke to him earlier after Umarex provided him as the closest repair guy.
I told him I would try the forum for a day or two and then mail him the debris.
He must know we are talking about the same poor gun or if not then at least think he should buy a lottery ticket today with odds of 2 calls for the same thing being unrelated.
JG Airguns in the states came up dry also.
There is a UK source that actually has them (back ordered though) but that may all cost more than the gun.
Worst case I convert it to non blow back by JB welding the rear valve and fixing the slide in place.
I hear and it makes sense that that willl boost the FPS but I doubt over 500 so I should be OK.
On a related note I also blew a seal on my old 38C and figure the co2 adn guns were in the sun on the table a little too long and over charged.
Duly noted!!!
Interesting also was that my new Corsman 3576 just would not fire until I backed off the gas a little. It must be well regulated to protect itself and stay below 500.
If I need Kyle's email I will PM you.
Thanks again.
Plinker

For your old 38C, if it is not the big seal for the 12 g CO2 cartridge, everything can be rebuilt with a o-ring kit from Princess Auto.

You should be able to get the schematic from the Crosman site and it is not very difficult to dis-assemble. I normally don't touch my airguns but when they are not working there is nothing to loose.

I did a rebuild on a 38 T and didn't have any problem.

Pete,
I think it is where the flexible gas tub enters the back side of the Co2 pearcing block. OR it is at the pearcing side.
Anyhow I have a whole replacement assembly I ordered back when I was trying to bring it back to life. I ended you sealing and keeping the old assembly so I will swap out and then fix the blown one.
I have the exploded parts views for the gun and a source for parts as i say with JG airguns.
Is the Princes Auto kit a standard thing in the airgun or auto section?

It is not in the airguns section.

It is in one of the aisles that has the assortments. Assortment of fasteners, clips and also o-rings.

I bought mine when they were on sale.

I found a guy in the UK who has the very part plus more and my contact at JG Airguns in the US says he knows the fella and is reputable and worth dealing with.
Since I am swapping leather for a new gun that works I will not need the part but good to have another source.
Just thought I would share the source (which I am sure many of you already know about) and good reference.
