where to get exchange injectors?

[ianainge]

My 63`ps have just rung up 500 hours and probably time for the injectors to be serviced ,i understand that normally they just do exchange ones that have been serviced and yours go off and get sold to the next bloke after the same treatment.
where would i go to these injectors please, i would have thought that main Volvo agents would probably try and sell you new ones at a vast cost.

Very helpful, used to dealing with Marine as well road diesels, will check them while you wait and advise on repair/ replacement.

Service injectors after only 500 hrs, is that right? Can you imagine EVER getting injectors serviced on a car. Do they ever go wrong? I realise they may wear after 1000's of hours but I've never heard of them being serviced??

I don't think it's on any of the Volvo services and if it was needed surely they'd try and charge for it.

Blimey - another expense I've never considered....

I had mine checked and tested at 900hrs+ on the old AD31, but that's cos they had the head off anyway.

Look up 'diesel fuel injection' in the Yellow Pages. As said earlier, most will check them while you wait and advise accordingly. I think I paid around £70 exchange to replace a couple of knackered ones. A check will only cost a few quid.

Hi Wiggo,

How many hours before yours were knackered?

63p's (as almost all Volvo's) use Bosch dieselpumps, any bigger Bosch car/truckparts specialist can supply these in the exhange program.

They have normally a Bosch numbering something : 0 250 *** *** *** like that.

Prices could be much better than Penta's as you prob. fig. out already...

We had a 'Friday afternoon' batch on one engine. Two broke up internally at about 350 hours, the other 4 on the same engine failed together at around 450 hours and it looks like one of the replacements has now gone duff at 600 hours (i.e after 250 hours of use).

We believe that at some stage someone has managed to put water in the port fuel tank (the diesel filler is right next to the freshwater filler), which is what caused the original 6 to break up. The latest failure is probably random bad luck. We had the four that failed together looked at by Bosch, who said they had never come across anything like it. Touch wood, the starboard lump has never missed a beat.

Phew - Thanks...you had me worried

Don't touch them. 500 hours is nothing!

Volspec were doing them for £72 inc VAT a week or so ago.

Have just completed around 1000 hrs with boat over 4 years.Injectors are showing no obvious signs of any problem and if they are the original units will have been in service for over 2,500 hours if the engine counter/log book is to be believed.

My diesel mechanic who looks after the vans & car swears by SAS Diesel Services who are on Slyfield Green Ind Estate at Guildford. Main Bosch agents and they also recon pumps & injectors while you wait. Tel: 01483 534570

I too would like an answer to the question on changing injectors in the car, never even occurred to me that one would do that so why would you want to on a boat, which is less subject to emissions tests?

I seem to recall that Audi/VW recommend changing the injectors on their TDi engines after 100,000 miles - something to do with wear affecting the spray pattern. Back of envelope calculation equates this to over 3000 hours - so quite a little way to go yet.

Not true, 500 hours is about right on these and testing each injector costs around £7 to test, well it does for us but we do have bloody loads of them. Exchange replacement is not expensive and can save you fuel, but more importantly save you big trouble especially if leaky injector pours fuel down bore.

 

[c_j]

I should have said about £12 for exchange injector as opposed to the £72 Volvo one.

Yes they do fail after extended service: the nozzles wear and the spray pattern becomes rough. The springs weaken lowering the firing pressure resulting in advanced injection. They may leak, dribbling raw fuel into the cylinder causing ignition problems. Poor spray pattern means a more irregular burn which can create hot spots in the combustion chamber. These may burn through the crown of the piston - particularly on marine engines which may run at high speed for extended periods.

Obviously the potential hazard of marine engine failure is far greater than a road engine, so pulling the injectors and having them checked and re-set at a major service makes more sense than in a car. Worn injectors increase the diesel knock and rattle, and can end up sounding as though the big ends have gone when they get really bad. By then starting will be getting quite difficult too.

Diesels are tough, and the injectors do last a surprisingly long time - but like any other mechanical part, they do wear and go out of adjustment after extended use, with potentially serious results both to the engine and the boat. Also unlike cars they may have to cope with inferior grades of fuel, with a far higher likelihood of contamination form water, dirt etc.

But 3000 hours sounds a more realistic point to have them checked than 500 hours.

totally correct leave them seems that poster is suffering from bbd syndrome ( boat breaking down syndrome )
