SPendrey Posted June 28, 2019 Share Posted June 28, 2019 I've been chasing a rattling noise, replaced the water pump because there was play in the pulley. Replaced the belt tensioner because it was weeping some sort of fluid (?). The timing cover is less than a year old, but there is a rattle within the pulley/bearing. However, the company I bought it from has gone bust, so no news there. The power steering pump does make a clicking noise when turned in the direction it would operate, but no noise the other way. Is this normal? The attached video (with rather poor sound I'm afraid) should illustrate the noise, but it is more of a clicking than can be made out. I'm thinking this is the next item for replacement? 2019-06-28 19.27.16.mp4 Quote Link to comment Share on other sites More sharing options...
Blanco Posted June 28, 2019 Share Posted June 28, 2019 As it is basically a small hydraulic pump I would expect it to be pretty quiet in operation,. Is it high miles? ,.. It isn't something I have particular experience of but I am sure someone will.......... Quote Link to comment Share on other sites More sharing options...
lo-fi Posted June 28, 2019 Share Posted June 28, 2019 It's a little vane type pump, so the vanes can rattle a bit when dry but not that much. I suspect something broken inside that's only catching one direction. Quote Link to comment Share on other sites More sharing options...
SPendrey Posted July 9, 2019 Author Share Posted July 9, 2019 I can report the replacement is in, and the noise is gone... but what I can't explain is why, having put the new pump in, the left hand wheel now rubs on the radius arm?! Nothing in the geometry was changed, could it simply be there's more "power" pushing the steering box?? Quote Link to comment Share on other sites More sharing options...
Sabre Posted July 9, 2019 Share Posted July 9, 2019 On the same topic, is it possible to overhaul these pumps ? Quote Link to comment Share on other sites More sharing options...
Maverik Posted July 10, 2019 Share Posted July 10, 2019 I've not seen someone overhaul one before, the earlier type fitted to 200tdi's is but this is quite a different design from the outside. Quote Link to comment Share on other sites More sharing options...
