Just reading a few posts on removing the injector pump
. It sounds seriously ugly. Lots of bits to remove before the pump
can be withdrawn, and at least one impossible nut to loosen.
Of interest to anyone following this, there are several steps (involving special tools) to lock the crankshaft and lock the pump
into position so there is no possibility of losing the timing relationships between the pump drive gears. (before the pump mounting nuts are undone)
After the rebuild
The final check involves removing an inspection plug
(on the injection pump), mounting a dial gauge on the injection pump and checking for max stroke travel. The pump housing can be rotated a few degrees to precisely time the pump stroke.
will run without this step being carried out, but it's best practise to "get it right"
