Hi, you will need the transmission or part of it as the diff pinion on a 2wd won't have a spline on the end for the 4wd gear.

The turbo won't like that sort of back pressure for to long. I just use a suitable sized bit of pipe and break the washer out from the centre. Shouldn't have to do it on a new pipe though!!

After removing the injector pump gear I found at some point someone had fitted a bolt that was to long holding the power steering pump on and this was pushing into the rear of the injector pump gear, hopefully good for another 50 years now!

I'm just replacing a set on a 990 with a ad4/47 engine with power steering pump aswell. Apparently hard to come by the power steering drive gear. But my wrecker supplied all I needed. Anyone know why they fail unexpectedly?

Hi, I have a similar problem on a couple of my DBS, it's more like worn selector gates and when I change from 1or R to 2 or 3 the 1 and R selector rail doesn't quite return to neutral which stops the 2 and 3 selector moving. Hope this makes sense!

Hi, I fitted a replacement radiator on my 1394 from sparex, but it gets hot when working hard, so I looked in the filler hole at the cores and the center row had half the cores missing compared with the old radiator! So beware

Hi. It maybe was tight but it sounds more like the drop arm bottom fork was 1/2 of a turn out causing it to contact the plough arm before it was fully lowered?

Hi, in the past I have used a tee fitting that you connect your water hose to and air compressor to then fit in the block drain tap hole. With the air running in aswell as water it seems to remove a lot more crap but have both radiator hoses off and thermostat out aswell.

Hi, I moved my hydrashift lever over to the rhs console when I brought my tractor a few years ago and when I fitted my loader last year I used the old hydrashift mounting holes in the dash for the joystick. Works well

Hi, putting a hose clamp on first then using your slip jaw pliers on that saves damaging the knob too

Hi, I think walvoil valve banks use the end you describe, they are on a lot of loader banks. You can manually push or pull the spool to lift the loader if you need to move it aswell

Hi Geoff. It was a sparex kit. The supplied orings don't protrude at all! Yes front and rear are the same size

Hi, I have a imp 990 I'm repairing for a costumer and I have a new bottom gasket set but the 2 half orings that seal around the main bearing housings appear to be to thin. They measure 4mm which I think they should be 3/16 or something imperial. Anyone know the correct size? Thanks Jason

It was one of these levers

I can remember on my father's 1594 we had a issue with the linkages behind the 4 bolt cover on the right hand side of the cross shaft, from memory an arm had come off and the valve didn't know where the linkage was
