ebdesignDEFENDER Posted May 4, 2009 Share Posted May 4, 2009 I have started engine this week (after staying for 10 months) and I heared a strange noise near the pump, it is like an bad or old bearing.Can it be because the bearing from pump lubricates with coolant an I put in engine just water?

western Posted May 4, 2009 Share Posted May 4, 2009 maybe the bearing grease has dried out by not being run, not much you can do to regrease them, if there's any in/out or up/down play on the shaft it might be wise to change it Quote Link to comment Share on other sites More sharing options...
ebdesignDEFENDER Posted May 4, 2009 Author Share Posted May 4, 2009 There is no play..can it be the alternator bearing? Quote Link to comment Share on other sites More sharing options...
crwoody Posted May 4, 2009 Share Posted May 4, 2009 There is no play..can it be the alternator bearing? Could well be, I had to replace a 300tdi alternator recently for the same reason. Why not take the fan-belt off and spin the pulleys by hand, you'll soon see then. Quote Link to comment Share on other sites More sharing options...
ebdesignDEFENDER Posted May 5, 2009 Author Share Posted May 5, 2009 I took the fan belt and by hand I can not hear anything. Quote Link to comment Share on other sites More sharing options...
jimmy_neutron Posted May 5, 2009 Share Posted May 5, 2009 I took the fan belt and by hand I can not hear anything. Did you start the engine with the belts removed ? Quote Link to comment Share on other sites More sharing options...
Les Henson Posted May 6, 2009 Share Posted May 6, 2009 Check the fan belt tensioner bearing, this is a common problem on the 300TDi engine. Les. Quote Link to comment Share on other sites More sharing options...
ebdesignDEFENDER Posted May 6, 2009 Author Share Posted May 6, 2009 I started the engine for 2 minutes without the belt--no sounds. When I fited back the belt---again the sound is present. With the hand I managed to find a play in alternator and the fan bearing what could it be? All I can say is theat the sound is not a frequent sound,it has no rithm - the sound repeat's n diffrent time. Quote Link to comment Share on other sites More sharing options...
ebdesignDEFENDER Posted May 6, 2009 Author Share Posted May 6, 2009 Also, spinning by hand has no result,because the bearing hears just when it is forced or tensioned by tensioner with belt. Quote Link to comment Share on other sites More sharing options...
markyboy Posted May 7, 2009 Share Posted May 7, 2009 Also, spinning by hand has no result,because the bearing hears just when it is forced or tensioned by tensioner with belt. Run the engine with the belt fitted, using a long screwdriver, piece of wood or similar device, place it in turn on the water pump housing, alternator body and the belt tensioner. I do not have to tell you to take great care whilst doing this not to get it caught in any moving parts. Whilst the screwdriver or whatever is against each of the 3 items, place it against an ear and if the bearing is worn/noisy the noise will be clearly transmitted through the listening device. This works really well in my experience. I stress that care has to be taken when doing this but it can be achieved with safety if you're careful. HTH, Mark.
