Diesel Leak from Timing Case

I do think your tinig is slightly out but just in case.

OK another silly one, not sure why it would cause you black smoke, but have you got the inlet banjo in the right position, there are two banjos that can be swapped but have a different orifice size. The inlet goes at the front of the engine and has a 13mm AF bolt head, the return pipe goes in the back of the pump and has a 17mm head size.

Cheers

Yes Mate Checked those.

If your diesel man has timed the the pump pulley wrong, you can work around it if you can scrounge a dti gauge, otherwise it is pump back to the diesel man and let him sort it out.

the small banjo hole is at rear, pin or the front mark is all the same,what have you had done to the pump

Had new front seal fitted

pump was locked presumably before removing the pulley

How is it locked JamestJames? think my mate just unbolted everything and took it t off

Don't know how the Diesel Guy done what he done

Just had another look, on the flywheel underneath is there a slot that lines up.?
Front pin and flywheel lined up, rotated twice Front pin goes back in but flywheel slot cant be seen,
Please forgive me if that does not make Sense,

how did he know which position pump should be in then when he put pulley back on

There should be a a slot on the flywheel that can be viewed through the wading plug hole. When the crank is on its timing mark.

That was shown in the videos I posted yesterday.( well Wednesday , but time flies) Did you watch them?

I don't know Mate. All the Diesel specialist told me was that the problem is front seal in Pump and to take it off and bring take it to him, and he would put new seal in.

Yes I did watch them but but left it to someone else to do. Im hopeless at stuff like this.

Yes seen the slot, but after rotating twice it was not there,

Have a feel with a screwdriver through the wade plug hole, if you can feel the slot just gently lever it back into the ctr of the hole.
It only takes a very small difference and the slot will move passed the hole. I think your timing is not quite right. I use the flywheel slot through the wade plug because it is more accurate that the timing marks for the crank.

Are you doing this with the radiator in place? as then you are looking at things at a strange angle.

Rad is in place but there is a good gap with conversion, no fans or cowlings in the way.
So after rotating twice and lining pin and front Mark back up, should the Slot in Flywheel be at the same position ie should be still seen through hole. ??

The flywheel slot should be at 6 o clock on the flywheel, the keyway in the front pulley should be at 12' O clock on the crank. Like this the timing marks should line up, that you can see.

As those two points are taken from the crank, if you rotate the crank twice then they should always end up back in the same place.

Does the fuel pin line up the pulley to the fuel pump? what size pin did you use? when the crank keyway is at 12 the flywheel slot is at 6 O clock and the timing marks line up?

Thanks. After getting flywheel slot at 6 , Keyway at 12, Pin fully in, and Marks lined up. 2 rotations and all back in same place Except Flywheel slot it cant be seen.

the slot at rear and dot on crank pulley align with every turn ie 360 degrees, you turn it over twice when checking a cam belt as cam and injection pump need to go round twice they go at half speed, the dot on crank front is as accurate as slot at rear, if dot on crank aligns so will the slot in the flywheel

Is the dot the one at 12 o'clock ?
So If Flywheel And dot on Crank were out what would cause this ?

if dot (scallop)on the crank pulley is fully aligned keyway is at 12,fly wheel slot should be aligned too unless you have an earlier flywheel instead of 300 flywheel
