Pse pump problem

[Daveboat]

Hi, first, thank you for letting me join. I am a marine engineer so am aware of mech and elect problems. I recently perchased an SL 350 ( my 10th merc) and have a problem with the pse pump. Sponge rubber around pump was wet, obviously sucked in moisture via pump air filter, recent frost had frozen ceramic rotor and it's smashed. Stripped it to find this out. Long and short, can anyone tell me where I can buy a spare rotor? I was reading some past posts, by someone saying that he had some spare pumps that didn't work, not too sure who it was, but maybe you could advise me if you have a spare rotor, obviously I would pay for it. Car details:- 05 sl350 , 65000 miles . Fitted two new batteries, start and consumer. Shortly after no central locking, check fuse behind seat f71, blown, fitted new fuse view again. Checked pse pump, found sponge motor housing wet. Pulled out pump found broken rotor. Many thanks in advance, if someone can put me in the right direct to source rotor. Daveboat.

Welcome to the forum Dave.

If you draw a blank getting a replacement rotor, this guy may be able to help. I see his location is Morden which may be close to you nr Dorchester unless its Morden Surrey!
Have a read at the bottom of his eBay ad.

Thank you very much for your answer. I have dealt with him, it was some years ago now. I shall try the guy in Morden as well. I will post what happens. These pumps are not that complicated to repair, providing of course you can get the bits, Will post the results. Much regards, Dave.

Hi Dave,
The problem has probably started by having water leak into the boot, you wouldn't normally get one of those sponge surrounds wet as a result of moisture being sucked through it, that would be a bad design in the extreme, especially with the faults that occur to these pumps because of water. If you've recently purchased the car then I suspect it's been wet for some time. When you get it repaired, and place the pump back down in the boot, then raise it off the floor with a spacer, something impermeable, I cut out a suitably sized rectangle out of an old garden kneeing pad, (the material was a bit like a flip-flop you wear on the beach), also line the recess (that will take the sponge casing) in some thick plastic, like the stuff from a stout rubble bag. If you have a leak, or any water accumulates down there, it won't get into the pump to screw it up. I can't recall right now if the 2005 models had the modified boot seals or not as the earlier ones were an issue, some earlier ones held up quite well whilst some others were useless - luck of the draw. If you have the original pre-modified ones then a new set is expensive, over £2000.00, there are fixes to the old ones though just a bit fussy to undertake. I think I might have a spare pump myself from when I had my 500, it doesn't work because of a circuit board fault but the rotors fine, let me know, I'm in West London near where the M3 ends.

Hi Dale, yes, I would very much like that pump just tell me what you want for it, my phone number is :- 07961 357744. The sponge rubber got wet through my own fault, I took the car to a car wash, high pressure water ect. Only the first few inches of the rear part of the sponge rubber box/ housing was wet. The tube from the lower manifold with the small air filter/ dryer that feeds air into the pump, just at the end of the filter, lies in between the two halves of the rubber box, and that's the part which was wet. The pump itself and all electrical connections were bone dry, I assumed that any moisture in or on the rotor would have frozen it to its housing, due to cold snap. Seemed logical, but of course I am guessing. I am going to take your very good advice regards to making it waterproof. I already have a piece of plastic about half an inch thick to put underneath, just to lift it off the boot floor. Thanks once more for everything and looking forward to hearing from you...king regards Dave.

I think it's in the garage somewhere, I'll take a look tomorrow and let you know. If I can find it I'll be glad to help. With regard to those rotors they can shatter anyway so it may not have been the freezing issue, you were maybe just unfortunate and it gave up the ghost.

Thanks Dale, I really appreciate this......Dave

Hi Dave, just checked and I do have it so its yours if you want it, it all looks perfect but it just doesn't work, just suggest an offer..

Hi Dale that's great, I don't want to insult you with a silly offer, I'll pay the postage and £30 is that any good. Figure out a way for me to pay you, I have an online banking facility. Dave
