Disco 1 Camshaft

Hi started stripping down to get to the cam everything was going fine until I got to the crankshaft spocket I used the puller which uses the 3 screw holes on the sprocket 2 hours later still the same any ideas much appreciated thanks

Silly question, but have you taken off the camshaft sprocket 1st? If you have then the crankshaft sprocket, timing chain and camshaft sprocket should come off together. The crankshaft sprocket is only held in its position with a keyway and should 'just' slide out.

Hi yes the cam sprocket first and then crankshaft damper came off ok but it’s the crankshaft sprocket behind the damper which is the problem thanks much appreciated

Its literally not held on with anything, the keyway just keeps it in the right position timing wise. Mine took a little wiggling to get it to come off but there's nothing holding it on to the shaft.

Thats a Gems engine, but its exactly the same process to get the timing chain off any V8, pics for reference so you can see what you're looking at up close

Hi thanks for your response tried a bit of heat and plenty of wd40 and clean up the shaft and the laser puller still no joy

Ah, I'll be quiet then, I only do V8's sorry

Counter intuitive, but it may be an idea to knock it back on. You've prolly got it just a teeny weeny bit askew. Invisible to the naked eye.
Never done this job on a D1, but I'd normally do it with two big screwdrivers or pry bars behind the sprocket, levering off the block, preferably spreading the load with bits of wood or summat. Never had a problem doing it that way.
