Re: 880 implematic cork crank seals

I initially questioned what I read in the manual about how to install these seals and took the advise and used 4 long studs as guides to lower the block down into position an inch above the frame then dropped it in. I used the #2 Permatex jointing sealant which does not wet and it is still nice and ...

Re: DB885 Exhaust Manifold Water Drain

It maybe fun to try to remove due to heat and rust. Try soaking it in some penetrating oil for a while then try to undo it.

Re: 880 Selectamatic Clutch Stop

If you have a local brake shop they should be able to bond new lining onto your band. Our local brake shop does this in their workshop and is not expensive to have new lining bonded to the shoes.

Re: Lucas Distributor

I believe that the wire from the ignition switch which is negative becasue of the positive earth goes to the negative side of the coil. Positive side of the coil goes to the distributor.
All I would like to know is if this is correct?

Re: Lucas Distributor

Another curious question about the coil that I must ask is which way to wire it up. Should the positive wire from the swsitch go to + or - side of the coil?
Something else to consider while you find an answer to my last post as well.

Re: 885 Fuel pump bolts

I'm sorry but although the stud maybe close in size the thread pitch and TPI are very different and will damage the thread if the wrong one is used.
One day have a look at a thread chart and study the differences then hopefully you will understand why they are not interchangable.

Re: 885 Fuel pump bolts

DO NOT USE M8 that is metric and NOT UNC. they are not compatible. Get anything metric out of your mind it is a ritish made tractor made when they used both UNC and BSF only Go online and buy the said size stud and nut to suit. Even a local nut and bolt shop may have this size as it is a common impe...

Re: Lucas Distributor

Questions for the resident retired DB serviceman.

Is this the correct rotor button for this DX4A distributor?

Is the picture of the distributor in the workshop manual correct for a 1954 30C?

Re: Lucas Distributor

Dont know if this has any effect on my ongoing problem but the condensor wire was in a position that might have allowed spark to jump to earth ??? so I re-positioned it. Also found some 'new old stock' for the Lucas distributor cap still in the box and a Bosch equivalent rotor button GL229 both to s...
