Elsewhere there is advice to get a diesel specialist to set up your injector pump, and some examples of what it might cost. But it seems (David Miller) that they might just "check the timing then set up on-boost correction using the smokemeter", or they might take the pump right out to "be mounted in their test stand, for which the front cover, fan etc has to come off, but you don't need to disturb the crank pulley".

It would help to hear of some owners specific experiences ... how much did you pay? do you know if they took the pump off? if they didn't why not? if they did was that because you asked them to? and did they fit, or recommend you fit, a new cambelt purely because the old one had been disturbed?

Dave, as you've seen in RM025E, a FULL setup of the pump is a lengthy process, involving multiple stripdowns to set shim heights etc. While the internal adjustments may change slightly with time due to wear, what most people require is a bit of compensation for worn injectors, and quite often, having the external adjustments "de-buggered" with- it's known that both exporters and importers fiddle with settings to give the townie some more "lift"

On the timing belt issue, while you are indeed "disturbing" the belt to remove the pump, all that is necessary is to slacken the tension. As the pump is withdrawn, the pulley can remain held in time with the belt using a couple of ties. No removal or unnatural bending, Only the same kind of change in tension that may happen during a warmup cycle. So in my book, no reason for replacement. Now if you were within say 10k of replacement anyway, that extra half hour to pull the bottom pulley and cover to change the belt would be economical, never mind sensible...

just a tip for holding timing belts in mesh when slack - use a bit of rolled up corrugated cardboard on the cogs to stop them jumping a tooth , it needs folding and stuffing between an engine component (theres usually something to hand). the pump pulley will be tight so dont take the bolt out completly or it will fly off, use a puller- dont ever ever try prising these cogs/pulleys of as you will end up at the dealers ordering new bits - the bottom pulley has bolt holes for a puller , trying to use a puller with the claws will crack the delicate casting of the pulley

Is the stop solenoid connected and getting a supply?
If so, try removing it and check the plunger is free...
