Hi to all!
this my first time . i did see somewhere on this site or on a link the
description on how to renew the bearing in the belt tentioner together
whith the Nr. for the bearing.Cant find the link again noe that i need it.
It is for a 3lt. intercooler diesel 2003. it be great if some one could help. This is a great site with lots of info. Cheers boggy bay
Like all belt tensioners mine was a bit noisy after over 200,000K on the truck. I was less than impressed with the $ required by Mr Nissan for the 'genuine' replacement.
So if you're a ZD30 owner here is how to replace the tensioner bearing for $45.00. NB Mr Nissan.
Remove the belt by loosening the tensioner as per the workshop manual.
Remove the tensioner from the truck (two bolts)
Dismantle the tensioner arrangement (1 bolt)
Place tensioner pulley and mounting in a vice and remove the bearing axle. This requires a special torque spanner. Mine cost $25.00. (1st outlay)
Press the noisy bearing out of the pulley. I used 2 sockets of the right size and just a decent bench vice.
Buy the correct bearing.
Here is the catch as most bearings are the wrong depth, but NTN bearing number WC87503 is the OE article and cost $20.00 (second outlay).
Once you give them the NTN number most parts places can source these bearings.
Press the new bearing into the pulley. Re assemble the whole tensioner. install the belt correctly, radiator shrouds etc etc.
and VOILA!! no more belt tensioner noise for $45.00 and a Saturday morning's work.
