D13000 injection pump seal

[quote="mojo66"]Need to replace injection pump seal at end of shaft to keep the oil from draining in main engine oil.
I was told to remove front engine cover, remove gear from end of injection pump shaft, unbolt injection pump from engine, lift off injection pump, replace seal at end of shaft, is that it other than making sure gear timing is put together the same?[/quote]

Remove the governor spring housing, disconnect the rack (below the base of the fuel filter, 4 -bolt cover) remove the injection pump and replace the 8B4967 o-ring seal (-318 trade size). Pump timing only couples one way with offset tang.

Is that along with removing front engine co er?

Not sure where that info came from. Not required to remove front engine cover unless maybe referring to removing the hood to get hoist access for the pump.

So you dont have to pull gear off pump shaft? Isnt that shaft conected to the gear?

Hi Team,
NO, you do not need to go into the front of engine timing gear cover.
The seal in question is mounted in a spigot at the front of the actual injection pump at pump camshaft level--note the direction that the seal lip faces.

Remove the injection pump by accessing the upper rectangular cover of the two just below the fuel tower. Other cover below this one accesses the bottom sludge trap for the filter tower--drain and clean out here whilst you are draining the tower of fuel.

In here is the Governor linkage from the front engine cover--remove pin., disconnect any associated external operators gov. control linkages, injector pipes,etc., and Inj. pump retaining nuts and remove the pump.
You may also need to remove the Governor spring housing on the rear of the Inj Pump--cannot recall if removing one of the oil filter caps and maybe its canister gives enough clearance for pump removal without having to disturb the Gov spring housing on the rear of the Inj. Pump.

You will see the lip type seal in the spigot and also the offset drive tangs for the Inj. Pump camshaft.
The drive tangs are offset so timing can only be correct--no need to do any special timing setting up except align the offset tangs to refit the pump.

Even if you yourself do not turn the engine or the pump--sometimes the pump lifter return springs can turn the camshaft slightly and upset the timing of the tangs so move the engine to suit and you should be good to go.

Chad at antique crawler parts and restoration told me its by far easier to pull off the front cover of engine to replace seal.
Not saying the way you said is incorrect but could you think of anyway of taking the cover off is another way? Is there any sense at all to do it the way i was told?

No matter if you pull the front cover you need to follow Eddies advice!
