[Shotimes] 94 ATX Timing Belt Idler Pulley EXACT Replacement

[Kevin & Cheryl Airth]

John:
 Good information but there is a MUCH cheaper and simpler repair. The timing
belt AND fan belt idlers on the ATX SHO use the same bearing. Not all the
fan belt idlers are the same so look carefully. That's all you really need
to replace. Yes it is the same bearing as used in the Nissan A/C pulley you
found.  Size is 35mm X 55MM. Part # NAC35BG05S10GST2F. Cost about $28.
 This number is on the bearing itself but is sometimes hard to see.
 Some people have had problems finding this. I have a local bearing house
that keeps these in stock if you can't find it.

> 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)

possible. The total cost with a new pulley, TB, patched covers and
