volvo waterpumps

[grafozz]

I,like many others, have leaking w/pumps on my boat .engines are md 2010,sand are on 600 hours .the pumps have been dribbling for 2 seasons .replacements seem to be around 400 pounds!. now ,I see in motor sport circles that remote 12v pumps are available for 80 pounds,they have big flow rates and if connected to run only with engine would consume no extra power,could this be done? any ideas on this ?

Do you think that would be better in the long run?

Using 12v pumps instead is a bit over the top, and how do you know that they wouldn't develop a drip in the long run? Engine cooling pumps (often made by Jabsco) are very simple devices and are inherently quite robust. Spares are cheap(ish) and easy to source. Repairs are relatively simple, even as a DIY job. If your pumps are leaking, you may only need new seals, which only cost a few quid. It would be worth fixing yours before contemplating more expensive solutions. Incidentally, your £400 replacement cost is a bit wide of the mark - you can get one from Jabsco for £175 inc VAT and UK shipping.

keyparts do them cheaper again, the prob arises on the earlier ones and the is exaserbated by cruising in silty water, lleyn marine in pwllhelli advise changing the seals every winter and larding it with grease as well. if the shaft is marked you can get it rebuilt and ground down

Very easy to replace seals and bearings using propietary parts from BSL or similar local bearing stockists. Remove complete pump and strip down on the bench, take bearings, seals and shaft to BSL who will identify them and you should get them 2 days later if they haven't got them in stock. Swop over the spring on the seawater side seal as it is stainless(If the originals have springs fitted). I did mine about 5 years ago, a Perama M20 which is the same base engine as the VP 2010, 2020 series. The shaft was slightly scored, so the new seal ran on a different portion of shaft and to date it hasn't leaked since. You can also get seal & bearing kits from Volvo Penta - try VOLSPEC who are very helpful. If the shaft is badly scored you might have to replace the shaft. Good Luck.

Re: Do you think that would be better in the long run?

thanks pvb ,for your tips.Ihave just fitted new seals this weekend ,so will see how they perform. Ienquired about replacement pumps last year from a s a p and found that volvo still have some design patents on that model so they were not available aftermarket yet .

I got a 'kit' from Volvspec in Tollesbury, Essex for my 2000 series for around 69 uk pounds. I was very surprised how cheap it was - for Volvo !

You get, new shaft, two bearing races, seals and gasket. I think also a new impellor ?

AS you say, quite easy to do. I pressed the bearings on with a vice.

Regards.
