When I pull a transmission in a 1989-up 240, I always remove the CPS (Crank Position Sensor) and bracket from the block as a unit; and then remove the CPS from the bracket on the bench.

Sometimes that requires soaking in penetrating oil.

Sometimes the CPS is destroyed in the removal attempt as it’s frozen to the bracket.

As in this pic – the plastic housing stayed in the bracket and had to be ground out.

I’ve broken a few brackets trying to replace CPS units – which then requires removal of the transmission.

I assemble new units with a light coating of moly anti-seize

here is a simple method which has never failed to remove even the most stubborn cps from its bracket.

use a pressure washer to thoroughly blast clean the area behind the cylinder head on the top of the bell housing.

the pressure washer will not only clean the surface but dislodge any particles between the sensor and bracket while lubricating at the same time.

once done use a robust pick with a 90 degree bend at the end to grab the sensor opening now that the bolt is removed and rotate the sensor left to right while remaining in the bracket. this puts no pressure on the integrity of the bracket but does loosen any tightness the sensor might still have within the bracket. once it rotates side to side easily it comes right out

That's a good idea and I'll try it next time I have a stuck CPS unit.

In the broken CPS in my pic though, I believe the bond between the plastic and bracket was stronger that the internal CPS bond. But, still, worth a try.

Can't hurt to lube up the new units, but the problem is caused by the failure of the sheathing on the electrical cable. Water enters and follows the cable into the sensor assembly, which is a copper coil wound around a magnetized iron core. The iron rusts, expands, and locks the plastic housing into the bracket.

It's all fun and games until your jeans don't fit.

Thanks Art. I usually replace any with a frayed sheath but I've run a couple of them that way for a few years with no problems.

That's a poor economy because if they do freeze into the bracket, you have to pull the trans.

Image file upload to the BrickPix Gallery is 1 megabyte file length at any image pixel size.

Do not use the relative HTML link in the Gallery. Use the complete Image URL. Right click the image to View the Image, and use the URL in the location address, tho this works with the brickboard URL and not the CloudFront URL this morning. Database index update, maybe?

Thanks Kitty. I know only one method works but I upload pics so rarely that I forget.
