Hi, have a david brown loader on a 1390 which is operated via a kontec 3 leaver bank in the cab, no cables,the main loader lift leaver is the middle one which has a two speed lift,when the leaver is pressed half way down this does the main heavy lifting,what's happening is with a heavy lift the load...

Right thanks for that, just started it this evening and all was fine anyway , strange!

Well before I started it this morning I bled it and air did come out after a few pumps of the lift pump and took about four or five pumps to clear it, the diesel was flying out no problem from the injection pump, it started and all was fine, I took off the lift pump bowl there was a little dirt on t...

Hi, have a 1490 that has started to airlock when fisrt started if was lying up for a few days,there is a small diesel leak coming from the excess fuel switch under the injection pump but this leak has been there for at least a few months with no probems, (the injection pump had been reconditioned le...

Great thanks, what I meant was there a 990 made without selectamatic or were all 990s known as selectamatic?

Just wondering does anyone know how to check if the temperature gauge on a 90 series is working?this one wasn't connected up but I found the wire and connected it to the sender switch and the gauge is moving into the yellow but doesn't go any further,new thermostat is in the engine and the cab heate...

Hi I got a reconditioned engine radiator for a 1490 turbo and all is fine but there is no cap on the radiator just a threaded hole where the cap would be,it's about a 1 inch threaded diameter or so,but just wondering what type of fitting goes into this and is there a standard radiator cap on top the...
