400-4 Tappet Adjustment using thread pitch?

<< < (2/4) > >>

DayvW:
Well .. in the end I resorted to the old tried and tested approach as I found it most accurate - though I did try based on a .7mm pitch (which seemed pretty close - perhaps .8?).  I did replace all the tappets last year (along with almost all the valves .. and some point they had all been doing battle it appeared!).  It is tricky getting it right - I tend to use 2 thickness gauges and judge it when the correct one goes in fine but the other (a tad larger) wont.  But I almost always get caught out by the fact that its best to just give the rocker a nudge each time to make sure its pressed against the valve .. found this by trial as I kept going up and down thinking I was going mad until I realised that sometimes I was testing the gap with it kind of hovering on the spring .. if you get my drift. 

Anyway tappets now fine ... my charging is  another story - I've found that the alternator is getting no power hence not generating a bean.  I have found the dodgy connection in the cable right close to the alternator - but not sure how to fix it .. and found that to replace the cable is an eye watering £60 odd (from DS).  So - I'm going to see whether I can repair it .... if anyone has any experience or tips on this .. I'm all ears ....

I don't know how your soldering is but that's the best way to repair it.

DayvW:
The wires just werent making contact with the plus .. really odd - so I pulled them apart and want to try to re-afix them.  My soldering isnt bad but I'm going to see whether I can find a new spade and bullet connectors that fit .. bullet may not be too bad - but the spade is actually a part of the white connector block ... some goolging needed methinks!

Green1:
The Hitachi blocks are simple enough but I wont recommend which one to get as I always get it wrong
pm BigAl he can supply them.

Google Vehicle Wiring Products,  they sell spade connectors (for connector blocks, get the spades with latch), jap bullet connectors etc.  I've used them for years
