Thread: sick defender

lambrover im going to replace injectors try bio diesel change filters again and put new oil in her then if all fails ill give her a comp test and think about forking out for a rebuild mate which i dont think will be cheap till last week she started first touch of the key so i dont think she should be in that bad condition touch wood ive had other diesel where they were so worn that they struggled to start . what i can i say one can hope that something goes well mate .thank you again

Not necessarily so. A few degrees retarded will cause difficulty starting from cold, but will start readily hot and still have reasonable power. I'll put it this way, IF it is the problem and it gets rectified, you'd notice a power increase when hot running. Like worn shocks, you don't realise how bad they are until you fit the ne ones...

Checking the pump timing is easy, your's dosen't have A/C right?

Remove the cover plate at the front of the injector pump on the front cover. (3 bolts, tin plate)
rotate engine until the 'u' shaped slot in the front of the pump gear is about at 10:30 O'clock.
You should be able to fit a 3/8"(NOT 10mm) bolt or drill bit shank into the pump through this aperture. If not, gently rotate the engine back and forth until the tool can be slid in about 50 to 60mm,.
Next, climb underneath the vehicle and remove the wading plug from the bottom of the bellhousing(If it is fitted) and look up to see (hopefully) a slot machined in the flywheel, central to the hole you are looking through. If the slot lines up and the timing pin is in the pump, the timing is fine.
If the slot isn't visible, there is a serious timing issue. If one side is visible, the problem is definately timing. This equates to about 2 or 3 degrees, and it is enough to cause poor starting from cold and smoke.

To adjust: visually centralise the slot in the hole, or use a timing pin tool to lock the crankshaft. loosen gently the 3 bolts holding the gear to the front of the injector pump through the front cover plate. While doing this, make sure you hold the main nut on the end of the injector pump steady with a 7/8" ring spanner. Keep hold of this nut while the 3 bolts are loosened, and rotate it slowly until the timing pin,(3/8" bolt) slips into the front of the pump body through the gear. When this has occurred, tighten the 3 bolts on the front of the pump, and remove the 3/8" bolt. rotate the engine 2 full turns and check that the slot in the bellhousing hole is central while the timing pin can be inserted. remember to make certain the pin and the locking tool(if used) are OUT and in your hand when you touch the ignition key


I expect a full report tomorrow.
