It produces new parts to zero the hours on engines. It is not an assembly line.

sorry. misspoke
To do that one need to disassemble correctly and put it back together correctly. in the right order. with the right procedure.
for all intents and purposes it is a production line.

Engine overhaul has to be a production line. They need to re-mill and re manufacture components that cannot be ordered from Russia. It is the nature of the breakdown in military trade that has caused China to transition to this stance. It is also this same stance that will inevitably lead to improving their own production capabilities.

They're probably remanufacturing most of the parts of the AL-31 engines, from the fan blades down to the the bolt and nuts except maybe the serial no. plates. Due to proprietary issues, each of the engine units have to have to the original number plates before the parts can be remanufactured. That's why they're still buying some more AL-31 engines until maybe some number is reached. At that point there are really no distinction between whether the engines are remanufactured or manufactured as new since each of them will still have the same serial no. when they were bought. In a sense, they will have hundreds of AL-31 engines to play with indefinitely with some of the older ones manufacture anew if need be.

To clear up numbers China imports of Al-31 are as follows
54 x AL31 between 2001-2005
100 x AL31 between 2005-2008
122 x AL31 between 2010-2011
and 123 x AL31 on order for 2011
Total is 399 engines imported
We also know that there are 4 x Regiments of J11B flying using WS-10A engines so that's 4 x 24 = 96 x 2 = 192 x WS-10A engines
We also know that J-15, J10B and few other prototypes have used WS-10A so the number of manufactured WS-10A is probably around 200+
This means there is a production facility for WS-10A, now the question is how many can they manufacture per year? The answer not enough!
The number of AL-31 imports don't add up to operational Flankers so it means China is making AL-31 somewhere along the lines because there is more than 400+ Flankers and 200+ J10A in PLAAF so that's more than 1,000 engines of AL-31 and WS-10A

@Lion
actually i'll be more worried if there is such rivalry between SAC and CAC that makes one bars the other from technology access, rather than production capacity
i prefer wolfie's pragmatism view on the matter
then again the picture was 1031, so there is no definitive proof that first batch of J-10B is with AL-31
regarding AL-31 production line, good luck depending on the Russian for spares, China have been doing it for quite some time

Some of the older flankers came with engines contractually.

That is correct, the deliverys of Flankers from Russia is as follows
24 x Su-27 (18 Su-27SK and 6 Su-UBK) delivered in 1992
2 x Su-27UBK delivered also in 1992
24 x Su-27 (20 Su-27SK and 4 Su-27UBK) delivered in 1996-1997
28 x Su-27 UKB delivered in 2000-2002
total 78
and
38 x Su-30 MKK delivered in 2000-2001
38 x Su-30 MKK delivered in 2002-2003
24 x Su-30 MK2 delivered in 2004
total 100
Total Flankers delivered 178 Out of around 400 operational Flankers of all variants, including Chinese built J11, J11B and J11 BS, so that means
400 minus the 178 delivered flankers minus 96 using WS-10A leaves approx 130 flankers and around ~220 J10A giving total AL-31 engines of 480, we know 400 were delivered so that still leaves 80 x AL-31 unaccounted for which were most probably built by China, unless with the initial flanker delivery some engines were delivered that we don't know about but I highly doubt it

2 x Su-27UBK delivered also in 1992

So they can assemble if needbe, but do not in peace time because of the contract with Salut.
