Busy few weeks, but finally got round to finishing this job up...
So start with getting everything clean as possible and get stuck in. All pretty straightforward until it came time to get the pump out. To say it was a bitch to get out is quite the understatement....
Next I made a bracket to clamp it in a vice, and stood it on the kitchen table. I have a very understanding wife..... In fact she had a needle and cotton buds out checking it was spotless! ACSD blanked. New gaskets in timer covers, governor cover, fuel cut solenoid etc. Fun part was the distributor. Back bolts off evenly and slowly to find gasket is so knackered it almost falls off, then slow and careful as I was, internals all fall in a heap as the distributor comes off. Marvelous. Remove all parts, fish out springs with tweezers, and reassemble. Problem is its very hard to tell if the shim under the pump plunger is located properly. In the end I found it best to put the shim in, place the plunger on top of it, then hold it in place as you put the plunger plates, spring seat, and spill ring in place. Then the springs and guides, new gasket, then distributor on. Next up the delivery valves. I did not disassemble. Simply removed, put new washer in, and bolted up again.
Reassembly was fun... The wife insisted on doing half of it, while I supervised! And a bloody good job she did too. Her being a smidge off 6' with skinny long arms and small hands, she can get in some places better than I can anyway! Setting timing obviously piece of cake with inlet manifold and injector pipes out of the way.
So job done. A moment of hesitation, then fires no problem and runs better than it ever did. And no leak. Happy days
