1996 U270 C8.3 belt tensioners

Two belt tensioners needs replacing (one for alternator and other for hydraulic pump).  Both are marked 00317 WRZ which seems to be Cummins parts (outsourced by Dayco?).  Looks like Gates # 38504 is compatible with both of those, is that correct?

Amazon has Gates # 38504 for $86.

Jamie,

Good seeing you again.  You got a great coach.

Agree that Gates makes an excellent automatic belt tensioner.

BTW, here is a 30 second video by Gates Corp on diagnosing failed tensioners: http://www.youtube.com/watch?v=uTLV5IU_IMM

I bought two of them from that exact same source for our C8.3 - perfect fit.  They were $75.51 in June 2014...inflation strikes again.

Rock Auto has it for $78, but you pay shipping, but no tax. However, retailmenot and type rock auto and you can get 5% discount code.

Always check rockauto.com AND amazon...it appears they both uses the same supplier, but it varies which one is the cheaper.

Brett: Agree that I got very nice coach, much better than what we have seen at MOT recently and it is reasonable priced too.

Great about rockauto.com, never heard of them.  I got Prime membership so shipping for that Gates tensioner is free (ordered two).

Gates tensioners are MUCH better than Dayco style.  Gates has a sealed body, whereas other styles have an opening where the end of the spring hangs on to the case.  We put them on ourselves. 

Look carefully for any spacer shims behind the original tensioners as they look and feel part of the original, but are separate and need to be put back behind new Gates.
