    300Tdi after market serpentine tensioner

    Hi Folks

    I need a new tensioner and could have sworn that I read somewhwere on this forum that a Commodore V6 (somewhere around the VP?) is a cheap alternative.

    Just spent the last hour or so trawling through old posts, all to no avail.

    Can anyone confirm that a commodore tensioner can be used and if so... which one.

    A prevailing part number that seems to pop up from time to time is a Dayco APV1004.

    ...I'm confused!!!

    BTW... fininshed the new timing belt this afternoon and all is well!! It runs much quieter than before!!

    For those that are interested... I pressed out and refitted a new fan hub bearing all for just $50.

    Regards
    Maarten

    The tensioner pulley is similar to the VP etc. The tensioner arm is different I think - although I could be wrong. Pick one up from a wreckers and do a comparison - we'd all like to find out if it'd work. I've read somewhere that the Dayco APV1004 is the whole assembly for a 300tdi.

    ps - what did you use for the fan hub bearing- a cut down ford waterpump one?

    Correct the Dayco APV1004 is the whole assembly for a 300tdi. I fitted one to my 98 Disco and bought it from Bursons auto parts for $117 inc GST 10 months ago.
    Most auto parts suppliers can get them, but shop around price does vary. Much cheaper than OEM

    Goodluck

    No... we sourced a bearing that had the same outside diameter, but it was a double ended type. Simply dropped it in the lathe and turned down the business end and cut off the other.

    Pressing out the old one is a bit tricky, bu tif done the correct way, it is near impossible to damage the front cover.

    We used a socket that was slightly larger than the bearing diameter and placed it under the bearing. (cover facing upward) Then used a small socket slightly smaller than the bearing shaft and simply pushed the bearing out by its shaft. When the flange meets the top of the casing, it stays put and the rest of the thing just slides out.

    Putting the new one in is much the same. Cover plate facing upward with large socket underneath. Press the bearing body in untill it is just flush with the front cover then support the shaft underneath and press on the flange. Dead easy.... no heating required and no special press required. We have now done 2 of them with the total cost being the bearing at $30 and the turning down of the ends at 1 x carton.

    Couldn't find any info about the commodore tensioner in my travels today. Looked at a VP one, but it looked fairly different. Coventry Motors in WA have a replacement for the OEM at $105, so I will be going with that.
