[Shotimes] 94 ATX Timing Belt Idler Pulley EXACT Replacement

[JohnnyVan]

I hope that this information can be of some benefit.  

Recently my timing belt idler pulley went south on my 94 3.2L SHO (135Kmiles) also damaging the middle and lower covers.   Having just eplaced the tensioner pulley and TB a few months ago I tried in vein to get a new F3DZ-6M250-A Ford replacement pulley (NTN 2TS2-DF0716LH bearing with dark green stripe) with no success.  I scowered the internet and did find a few used sources one of which I purchased but turned out to be a dry bearing.  I received no further replies from the remaining internet sources.  No luck at salvage yards internet or otherwise.  What to do,  without the pulley my SHO is KAPUT.

Well after two months of on and off web research I finally found what appears to be an NEW exact replacement pulley.  The pulley is Mfg by Joyku (part # BT-10526) and I was told by John Hou at Joyku that it was sold to Nissan.  He also sent me a dimensioned drawing and picture and said it would cost $52 total incl s/h to purchase one (shipped from Tiawan). The drawing matched up great.   I did a bit more research and got a few more details from www.masterautoparts.com under Nissan (they showed 25 pcs available)

I gave my mechanic this info and he ordered one through Nissan.  The part number on my repair receipt is

13077-F556510

My cost was $82.  As for the two TB covers we patched them up as best as possible. The total cost with a new pulley, TB, patched covers and serpentine was $500. 
 
My SHO is home now but I am seriously thinking about ending our relationship before further parts availability drama strikes.  Any additional information on parts availability issues would be appreciated.
