Re: JCB 3CX Fuel Level Sender

Start by checking Fuse 12 - could be an easy fix. Do you have a test light or multimeter? Can you get to the back of the gauge? There should be three terminals: One terminal will be 12V (Green), one to ground (Black), the other will go to the sender (Green with a Blue Trace). If you short the sender...

Re: Kobelko LK400 how to find parts

If you are lucky, somewhere along the top surface of the belts will be the size moulded into the rubber. Often the size is printed on and becomes unreadable with age. Either way, they will be an off-the-shelf part available (as above) from and decent belt stockist. If you measure the width at the to...

Re: JCB 3CX-4 Sitemaster 1989 Dipper Ram seal replacement

Am I correct in thinking this sleeve protects the nut seals from the threads (and acts as a lead-in for the seals)? Several solutions I have used in the past include: - A layer of stretchy insulation tape carefully wound on tight so the edges butt up to each other, but don't overlap will protect fro...

Re: Jcb3c 2

I would think a 15w/40 would help keep up oil pressure in warmer weather on an old engine. Yep - that's certainly my reasoning. The downside, particularly in cold weather, it takes significantly longer for the oil pressure to come up. It's always a trade-off between No. of starts / run time / temp ...

Re: Jcb3c 2

Any suggestions about the best type of oil to refill with? Especially now I will have a clean sump and clean filter . I'd stick with the theme and go for some clean oil :P As for grade, 10w/30 mineral oil is the start point, then you decide if something else suits you better. Personally I use 15w/4...

Quite right - a smaller 4.

The MF168/180/184 had the 4.236 and is likely to be configured the same.

"other modifications" are a bit of a problem, but the 4.236 is easy - start with an MF65 manual or Perkins manuals.

Re: Perkins phaser 1004 in 3cx running bad

Looking at it logicly, you need three things to start a fire - fuel, air and an ignition source. For a diesel, the ignition source is the compression - if the compression is low, it will be hard to start. The injector spray pattern / fine atomisation also makes a big difference to the "ignitabi...

Re: JCB 3CX stabiliser seals - where does the smallest oring go?

First, check the part number of your seal kit - it should be: 991/20021. I had trouble with the same pin on one side as it had rusted solid, but I have no idea what the butcher had in mind when he welded up yours. The pin should only be held in place by an M8 bolt through the eye of the ram. As for ...
