PeterW Posted September 11, 2006 Share Posted September 11, 2006 Evening all... Just been doing the pre-MOT checks on my SIII and found a steady drip drip drip of diesel from the fuel injector pump... It seems to be coming from the gasket between the injector body and the rectangular block where the throttle and engine stop connects to. Does that make sense...?? So, 2 questions... - can this be easily repaired/replaced insitu..? - anyone got a CAV pump they want to sell..? - anyone got any other bright ideas..? Cheers Pete Quote Link to comment Share on other sites More sharing options...

isuzurover Posted September 11, 2006 Share Posted September 11, 2006 Couldn't be easier to replace, and if I remember correctly you don't even need t bleed the pump afterwards. Just remove the nuts holding the engine stop and throttle connections on, then remove the two bolts holding the housing on the side. It is rare for the housing gasket to leak, it is usually the o-rings on the engine stop or throttle shafts. Quote Link to comment Share on other sites More sharing options...

I take it if I have a large selection of o-rings and I should be able to find the right ones...? Nothing bizarre like odd nitrile plasticsed vulcanised virgin rubber...??

steve_a Posted September 12, 2006 Share Posted September 12, 2006 I have a spare pump in the shed for free. collecting it is an issue at the moment as the shed is in Gosport and I'm not... it also leaks around the stop and throttle shafts, so would need O rings, so it would be a repair and then straight replace. bit on the heavy side to post Quote Link to comment Share on other sites More sharing options...

Lars L Posted September 12, 2006 Share Posted September 12, 2006 The gasket in the pump is not that difficult to change, just a bit fiddly to get everything in position when assembling. It sure needs bleeding afterwards as the housing is filled with fuel. The gasket is a "square o-ring" that sits in a groove in the lid and might need to be held in place with a few drops of gasket goo during assembly. If the pump leaks around the shaft, it's most common that the shaft itself is worn so changing o-rings only isn't always the cure. A tip that was given to me when I had a "diesel specialist" to change it, was to buy a shaft for some Peugeot as it was a lot cheaper than one for a Land Rover but use the original spring. That was however here in Sweden, in the UK that can be a different matter... Quote Link to comment Share on other sites More sharing options...
