The motors in come inside for some nice aircon and a cool drink.
Just have to bolt up all the crap and do the wiring now might even have another go at it after i cool down.

Hey mate you got any pics of what your doing be good to see

[97_gq_lwb]

What's to see.
Pretty straight forward swap other then the engine mount and wiring wich i will post up info and pics on when i have finished it.

Throttle cables are different as well had to change it over.

Ok the wiring is pretty easy i used the rd28 harness lay them side by side you will see that the gearbox connectors are the same just that one has to be moved to match so start there.

Then from that point on strip back all the coverings and tape
The starter wire is straight forward copy the same position as the td harness.i had to change the plug on the end to suit.
Then next up the harness is the oil pressure sender i used the rd28 one to match the dash so put the plug in the same spot as the td42 harness and tape it off.
I then removed the tps plug and wiring as it isn't needed any more and the white glow plug wire.Well i actually used the white wire and swapped it over at the other end of the harness and removed the red one. i then removed the td42 connector on top of the manifold run the rd28 glow wire direct to the glow plug rail with no connector in between and shortened it to suit put a new connector on the end..


I laid it out on the engine at this point to make sure everything would reach to the locations i wanted.
I changed the injector pump plug to suit the td pump and run it to the same location as the td harness.

Now i run the tacho plug to the same spot as the td42 harness and the red glow wire also cut and extended the temp sender wires.
So now the glow wire tacho wires and temp sender wires are all heading in the same direction.
With the temp sender wiring i run mine down the path of the tacho input then up behind the alternator bracket so measure accordingly with your extensions.
Or do as i did extend the wires over a foot and a half tape up and recover the harness as you go then fit it all up to the engine and then cut and join the temp sender wires last.

So i fired it up for a few seconds i get the glow light flashing because of the afterglow no longer being there will try removing relays or swapping the control box over but so far so good oil pressure light and gauge is working tacho was working .

I'm interested to see what you find with the glow light flashing.

Was there much to do adapting the clutch slave cylinder to the new gearbox?

I used the lines and slave from the td42 even the bracket in the left front near the firewall that holds the td fuel filter etc.
The master for the clutch was the same size so just screwed the line straight in.

Glow light initial works fine goes out then it starts flashing until the temp rises once it has been started warmed up and restarted their is no flashing.
I am trying to think of a way around it as the td42 module doesn't plug in the same.
It would be good to have a schematic on the glow control module and just bypass the flasher circuit.
Anyone got any ideas.

[97_gq_lwb]

Just had a bright idea i can just wire the dash light to the initial feed to the glow plugs wich will bypass the flashing and still come on when the initial glow is working..
