Timing Issue?

[Adjadean425]

I believe I have it. Reluctor must have slipped. I punched it around to match the pic of yours and a pic of one online. Starting fine and no codes so far. If it slips again i may just replace the camshaft but I’m gonna let it ride for now. Thanks again for all of your help.

ok great, and you are welcome glad you got it going. tell me did that ring move easy? if it did expect it to move again. those are pressed on at the factory with an interference fit. on your cam, i bet the tolerances were such that the cam od ran small and the ring id ran large



tell me did it move rather easily? if it did and you start with the codes again tap it as far off the cam as you can and get some red Loctite. yes red is the hardest you can get and tap the ring off and put the red Loctite on the cam surface and if the ring is loose at that point move it around to get the red Loctite on as much of the cam and ring surface as you can and then tap it back on the cam and back into position and let it harden. when that stuff hardens you have to heat it up almost red hot to get it to loosen up.


if the codes stay away for a time but it does return you may also try to drill it and tap it and put in a set screw and Loctite that also and then you will be golden.

ok i just had a brain fart idea if that ring does move yu can put it back and do this, you can do this is much easier than drilling and tapping it. get 23 or 4 roll pins like 1/8" pin and drill into a pcs of steel for testing the drill against the roll pin. tap that test pin into the hole to see how hard it taps into that hole you just drilled. if it taps in a bit hard that tells you it is fitting as it should, they need to be a bit snug. if it is loose then get the next smaller drill. or get a roll pin-drill set 1/8" then you have the correct size.
now put a magnet next to the low spot on the cam that will catch the shavings and drill into that so that you go about 1/8" deeper than the roll pin is long. and set that pin down below the surface and then take a center punch and right next to the hole make let's say 3 center punch marks like 10 2 and 6 so that it covers that hole you just set that roll pin into that will hold the pin in the hole and the ring will not move as it really has no force on it. how to stake YT they do a pistol but it is the same thing
then take a pencil magnet and clean up the rest of the shavings this will be the best fix i think will be your best option and save taking it apart and getting a new or used cam.

i have set lots of roll pins in y 40 years in machine repair. i'm sorry i did not remember that. but then the bulb came on and now you know. the link below shows how to stake a pin. he is doing a gun but the process is the same. it will save time and money. if you work in a shop ask a maint man if he can get you a roll pin and drill to do the job. i helped out lots of people at work. most people that need help seem to migrate to their maint guys. good luck let me know how it goes

It didnt move very easily. But If the codes come back i will do the roll pin idea. That should work and be a lot easier than drilling and tapping for a set screw. As hard as it was to punch around to the location its hard to believe that it would slip that much. But Ive been doing industrial maintenance for 15 years so ive saw a lot of stupid stuff happen.

ok i retired form 40 years in machine repair. an i have rebuilt more engines than i care to think about. but now you know if you get that again how to fix it rather fast and easy. use on of the off sections the lower area on the cam so it will not trigger and put a roll pin and stake it and your golden. but like yous ay give this a try and see how it goes. and good luck to you.

Hey buddy. My Mother has a 2013 terrain. Same engine. It blew the rear main seal. I pulled the motor changed the seal and did timing chain while it was out. It’s all back together. No leaks and runs fine. But the rpm gauge isn’t working and has crank shaft position sensor code. Any ideas.

make sure you did not forget to plug in the cps or look for a ground wire not connected the rpms may come from the crank and that is why you got the crank code. good luck
