crank sensor shim question

hey chaps.
i was wondering if per chance anyone knows what the size of the early td5 crank sensor shim is, the problem is land rover have them on back order and i need to sort this asap. if anyone can help me with this i will be eternally grateful

Make your own up. The original LR items are 0.5mm thick (you fit more than one if you need more clearance) but you dont need to be too accurate. So long as the nose of the sensor does not contact the flywheel you'll be fine. You are looking for a final running gap of about 1.5mm.

If you have any engineering measuring tools then you can accurately measure the distance from the sensor mounting face in the bell housing to the flywheel making sure your indicator does not go down into one of the 36 drillings spaced around the flywheel. Take measurements in at least six (the more the better) equally spaced places around the flywheel and record them. Then accurately measure the sensor mounting face to sensor tip and deduct this from your previous smallest measurement. If the result is less than 1.5mm then you need to add the appropriate sized shim between the sensor and the bell housing mounting face to give you the required clearance. This gives you a starting point as to how thick a spacer to add.
If the result of your careful measuring and calculations is 1.5mm or larger then you dont need any shims.

In all cases mark the end of the sensor with a marker pen, fit the sensor without its O ring and mounting screw, then turn the engine over carefully by hand a few times. If you can get somebody else to turn the engine while you keep your fingers on the sensor you will feel if it is rubbing (it should not be if you measured properly). Take out the sensor and have a good look for any signs of interference. If there are no marks in the marker and your previous calculations are accurate then you are good to go. Clean the sensor tip before you fit it. My CP sensor has no shims fitted and neither did my previous engine.

u r a legend! ta very much like!!!!

yes, mine doesn't run any either.

get it running!

Wow. I just yanked oot the auld sensor and bunged a new one in. Everything is running fine ever since.

Chances are you left any shims stuck in place on the bell housing or there were not any to start with. All engines are different hence the need to shim some of them to get the clearance. The sensors should all be pretty standard in length unless BritPart make one in which case you'd probably need a block of 2x1 as a spacer

two words ... bloody td5`s!

Does it run yet?

I certainly hope that is the case, it runs fine as it is so I'll leave it alone.

Hi Fleck!

What were the symptoms/problems in the beginning?

Rgds, Lars

started out that it would sometimes start just fine and others just wouldn`t fire, would turn for ages quite happily but just wouldn`t catch. I eventually with some rather in depth measuring made up a shim out of an old washer and some creative grinding. Also removed an old tuning box that was redundant but still in the ecu and replaced the starter motor as it wass drawing an ungodly amount of current. in hindsight, i reckon it was probably the starter all along but i will never know as the vehicle is long gone.
