Can anyone explain why the clutch setting is different in the Haynes Manual for the series Petrol and Diesel engined Land Rovers (later assemblies)?
The Petrol manual suggests setting by measuring the plunger length at the Slave Cylinder whereas the Diesel Manual suggests depressing the clutch pedal and measuring the distance from the piston to the retaining cir-clip in the slave cylinder!
The gearboxes are the same regardless of power unit, so why the difference? I'M SURE THIS WILL BENEFIT ALL SERIES OWNERS.

Two different master cylinders. Early ones need the rod adjusted for clutch free play, and the pedal stop for comfort. Later are self-adjusting for clutch plate wear, but need to be set when a new plate is fitted.

Hi
Thanks for that but, I'm comparing like with like in the Haynes manuals, later clutch; petrol engine and later clutch; Diesel engine, with each version describing a totally different set up for the same clutch. The Autobooks manual, which covers all engines in one cover, gives instruction on early and late system types and one setting instruction for each. Is there anyone familiar with the Haynes publication who is able to provide a categoric setting technique for the later clutch version that is applicable to ALL series engines?

I'll be honest, when I replaced my Master cylinder, I ignored that and set the correct pedal height, appropriate 'free play' and went from there. Biting point is when the pedal is about 40% from the floor and seems to be fully engaged about 70% off the floor. After all, it's just a piston pushing fluid and there is only so much adjustment you can make. I'll have to have a look at the proper Workshop Manual if I get time later. The Haynes Manual does contain a few porky pies here and there!

Thanks, much appreciated.
