Re: New electrics

Interesting problem with damage to the inside of the cap. If the engine starts easily then timing should be ok. With the engine 'dying' at higher revs is this when driving and engine is under load or sitting still and looking for high RPM? Could be fuel starvation and maybe stuck or sticking needle ...

Re: 30C Starter Motor troubles

Yes the young ons have no idea on how to fix things, only replace them. Trying to get cross refference numbers from Lucas parts is getting tricky as I have found out recently with other electrical parts for the D.B. but I think I have that side of it sorted now. Very hard to find a tradesman who now...

Re: 30C Starter Motor troubles

No problems here with DIY but have been frowned upon by others about not being 100% supportive of one spare parts supplier often mentioned here. With a DIY could you measure the resistance of the good winding to give you a base number to work to to rewind the damaged field coil? Or, go around to som...

Re: New electrics

I thought the 30C used a standard reach 18mm plug. What brand and plug number have you got?
You mentione a 'worn distributor cap'. What is worn?
Hopefully your #1 not firing is the HT lead.
Did you check the spark timing from the flywheel while waiting for the battery to charge? Certainly worth doing.

Re: 30C Starter Motor troubles

You have done a nice job on cleaning it all up. Try contacting the local DB club as a source for another starter locally. Chances of finnnnding just windings here will not be impossible just harder than buying a complete unit. We wont be back home until early next week and if you like I will try and...

Re: Cropmaster dynamo repairs

From memory the shaft you are menioning is the main shaft of the dynamo and is not replaceable it is a through shaft from one end to the other and the old bearing needs to be pulled off and the new one pressed onto the shaft.

Re: 30C Starter Motor troubles

Gday Roger and welcome to the Forum. There are some parts that pop up from time to time for our DB tractgors so keep an eye on the usual auction sites. Next make time to find the David Brown Tractor Club of Australia and to join them would be good but ask them if anyone has a spare starter. I recent...

Re: New electrics

Now this thread has my attention. I can't wait for the replies. Definately check your igniton timing, it wont cost anything but time. (pun intended). Could not stress enough to replace the condensor as well when changing your HT leads and points. It is a system that must work together to perform at ...

Re: New electrics

I buy HT wire cored leads by the metre and fit new connections myself so that is yet another option. If you do buy from David Brown Spares they also have a set of colour coded HT leads which were on your machine from new. No matter which way you go buy a new condensor while your shopping it might be...

Re: 990 Selectamatic Linkage Geometry

I would be looking at his top link too for the haybob. If it clears the ground near the tractor and is touching the ground at the rear then top link issue is high on the list to look at. But with out a clear picture of the complete set up, tractor, lifting arms, top link and haybob we can waste time...

Re: 990 Selectamatic Linkage Geometry

Sounds like there will be 2 fixes for the one problem, shorter top link will solve the problem. See if you can source a good second hand one or buy new from your dealer.

Re: 990 Selectamatic Linkage Geometry

Still no picture of your one. Are you able to post a picture of it so it might get resolved?

Re: 990 Selectamatic Linkage Geometry

Still need a picture from different angles to work out what is wrong there. This is why I asked if there was an adjustment available like on some old ploughs or if there are other pins to connect it to that are down lower.

Re: 990 Selectamatic Linkage Geometry

Sounds like the mounting points on the implement are not correct.
