Jackeroo T/D Hard Starting.

With a statement like "the "shaft is carboned up"" your cousin is about to get shafted.

The problem didn't happen to arrive immediately after a service did it?
Get your cousin to change the engine oil and filter to EXACTLY the specification in the owners manual and see what happens.
The Jackaroo's use the engine oil in the injectors.

Geoff.

Agree with Geoff re the self testing first. Would go further and suggest the second oil filter too. 10-w40 oil is the go for mild climates - you could try 5-W30 for chilly climates (it matters). With both oil filters renewed, and a new air filter too, you could give it a confident try - failing that, a specialist diesel / turbo technician seems the go. Note: You can save on the main oil filter by using the Ryco equivalent - suggest genuine for the small (despite the listing, the Ryco Z79a for the small might be tight). Also, give the mounting area for the small filter a good blast off with a hose and a dry too (air line), prior to changing that filter - there may be crud around the seal area - that filter faces down (passenger side of the donk - rear) - don't want crud in that oil gallery.

Hi John,
Had a similar problem with my Courier diesel, real bugger to start, particularly when cold.
Have you had the Heater/Glowplugs checked out?
If they are not all 100%, replace the lot (about $30 each) and eliminate one likely problem.

Oil viscosity 5w-30 required

Glow plugs - three out of four of mine were blown get them from www.glowplugs.com.au and save an absolute bundle. They have a tendancy to get stuck so if one gets stuck don't keep going and break it like I did just leave it in. The engines will start easy enough on three. Recommend a little antisieze when putting the new ones back in.

If it has had a recent fuel filter change then there could be a small air leak otherwise the primer valves are known to occaisionally go and allow fuel to travel back when not running.

Injector O rings check radiator coolant for diesel smell or sump level for any increase in level. If diesel found to be getting into sump then don't run engine as if enough diesel gets into the sump the motor will run on and blow up. A phrase for this on these motors was "chocolate motor syndrome"
Another test for these failing is to put some clear hose in the diesel return line at the back of the head and look for bubbles in the return stream of diesel.

There was a recall in the Uk for a problem with the oil induction pipe in the sump.
This cracks or come loose allowing air into the hydraulic injector oil supply. This causes a hard start and rough running condition, another fault my Jack suffered.

Oil pressure sensor for the hydraulic injectors and a number of other sensors can also create havoc such as the flywheel for manuals and the engine crank sensor these are a less common problem

best of luck

Not sure what model Jack ya got but from what I been led to believe the later ones came out with 2 starting batteries for this reason.

This what I picked up from one of my earlier posts 'Jackeroo Batteries'

Hope this info helps so you can at least you can ask the right questions.
