Harry m Posted July 1 Share Posted July 1 I've got a small leak on the injector pump on the 90 it starts bang on and runs with no problem, how big of a job is it to get off would I need any special tools. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted July 1 Share Posted July 1 To do it properly it's taken the whole pump apart, where it's leaking is basically the first bit with a seal on to go into the pump. Given the cleanliness required you want the pump off and on a bench. A few have stretched the ring over the housing into its groove by carefully pulling the rear housing out. Personally I don't see why you would get an O ring, knacker it like that during fitting and think it was agood idea. 1 Quote Link to comment Share on other sites More sharing options...
fmmv Posted July 2 Share Posted July 2 To answer the question of how to get the pump off, there are at least 2 ways. One is to take off the timing cover etc as if changing the timing belt then unbolt the pulley and unbolt the pump, having undone the plumbing etc. You need timing pins and probably a tool to hold the crankshaft while undoing and doing up the crank pulley bolt. But if you need to change the belt this is a good way. Alternatively you can get a timing tool set, about £30 on the well known sites. This includes timing pins. You set the engine and pump to the timing position with the pins, and remove the bolts holding the pump pulley to the flange through the small cover in the timing cover. You then bolt a disc (also included) to the outside of the cover to hold the pulley in place and draw the pulley off the pump. As you tighten the bolts the pulley is held in position against the cover. You can then unbolt and withdraw the pump. Returning the pump is the reverse of disassembly. There is no need to disturb the timing belt etc this way. 1 Quote Link to comment Share on other sites More sharing options...

Personally, I agree with you that it seems a bad idea. Quote Link to comment Share on other sites More sharing options...
Harry m Posted July 3 Author Share Posted July 3 I've seen the video pulling thr O ring over the block and I think what has been said is right I really don't want to take the pump apart so I'll will take it of and take it in to have it sorted better to have some who knows what they are doing look at it. Thanks for the replies Quote Link to comment Share on other sites More sharing options...
Snagger Posted July 3 Share Posted July 3 It was a long time ago, but I used Diesel Bob Tuning to rebuild my pumps and injectors with good results. Quote Link to comment Share on other sites More sharing options...

Phill B Posted July 10 Share Posted July 10 I had Welham Diesels build mine. £488. Mine was a mess inside though, full of rust. Still worked well surprisingly. Last owner ran it with no water seperator. Quote Link to comment Share on other sites More sharing options...
