Torque Setting , Crankshaft Pulley

[bordonladdie]

I am about to renew the timing belt on my 1997 Land Rover Disco 1, w/ 300 TDI engine (105,000 Kms). The repair manual is quoting 80 NM @ 90 deg, whereas I have seen a figure of 340 Nm in other articles relation to this repair operation. Appreciate your help. Thanks

Torque Setting , Crankshaft Pulley

I am about to renew the timing belt on my 1997 Land Rover Disco 1, w/ 300 TDI engine (105,000 Kms). The repair manual is quoting 80 NM @ 90 deg, whereas I have seen a figure of 340 Nm in other articles relation to this repair operation. Appreciate your help. Thanks

The data I have on the 300 TDI states:

On the 300 TDI the flywheel to crankshaft torque specs are 40 Nm then turn an additional 80 degrees for final torque.

Tv to pulley is 80 Nm
The main bolt on the front of the 300 TDI, the main crankshaft to pulley, ( the big one), is 455Nm or 336 foot pounds…….. Tightening this will separate the men from the boys in a hurry. Better get a good lock device to hold the flywheel when doing this, don’t use a screwdriver on one of the flywheel teeth, it will snap off either the screwdriver or chip one of the flywheel teeth at that torque. In the manual they use a ¾” drive torque multiplier, as I know of no manufacturer that makes a ½” torque wrench that goes to 350 Ft Lbs. Even my Snap – on Torque wrench only goes to 250 Ft Lbs. Land Rover uses a special tool to hold the pulley, part number: LRT-51-003. I would highly recommend to get one, and a ¾” drive torque wrench, if you do not already have one.

1 pound foot = 1.355 817 952 Newton meter

Hope this helps………….. Chongo

Thanks for the info,Chongo. My manual is very misleading. I am making up my own locking tool,don't trust my own welding ,so I am getting an experienced welder to weld it up.
