Updating Cams when changing timing belt?


Recommended Posts

Has anyone put in the 94-95 cams when changing their timing belt so you could use the longer lasting 90k mile belt? Is this possible? I assume that it is, I'll be changing mine soon and would like to be able to do this.

yep, according to my VIN my 93 was only about a month off from getting the round tooth

My wifes truck was in the same boat. But she's running round tooth too. Don't pry on the Crank gear, Get a good grip on it and pull straight back on it. While pulling rapidy tap on the end of the crank snout with a hammer. This is how I have pulled every Crank gear on every nissan I have ever worked on. The rusty ones take longer but it gets there eventually.

Other than that Its a very straight foward swap and don't forget to do your camseals and crank seal.


Stay away from Victor Reninz cam seals. I had my left and right cam seals leaking after 7k miles.


Gates, SKF and NSK are good.

But be careful, SKF has started selling other seals under their label. An SKF made seal will have SKF printed directly on the seal and usually comes in a small cardboard box. Their re-badged seals (unkown make) do not say SKF on them but come sealed in a SKF bag.

My crank gear slipped right off, no tapping needed.


I don't believe you need to swap cams, just the cam gears and crank pulley. Its also 105k miles on the interval.

Bingo! You have to pull the gears to change the cam/crank seals anyway so it really isn't any extra work at all.

There is a neat trick I learned to keep from turning the cam shafts while taking loose or tightening the cam gear bolt.


- Find a large socket that fits snuggly in the large holes of the cam gear.

- Attach breaker bar

- Find socket that fits cam gear bolt.

- Attach ratchet/breaker bar.

- Loosening Right Cam Gear (as facing engine):

* Insert large socket into hole of cam gear closest to 3o'clock.

* Aim breaker bar towards the 9o'clock position and to go just below the cam bolt

* Put cam gear bolt socket with ratchet/breaker on cam gear bolt. Ratchet/breaker arm to go towards 9o'clock also, but above other breaker.

* Push down on ratchet/breaker with cam bear bolt socket and pull up a breaker with large socket.

* The breaker with large socket needs to hit the side of the cam gear socket for this to work.

The closer to the bolt head end the better (i.e less chance to flip the cam gear socket off the bolt head.

- Loosening Left Left Cam Gear

* Same as Right except positions are flipped and the large socket breaker arm goes above the cam gear bolt head.

- Tightening Either Gear

* Same positions as loosening, but position of larger socket breaker arm is swapped. If below for loosening than above for tightening and vice versa.


It's been a few years since I actually did this so I'm going from memory and figuring it out in my head. I know it worked much better than trying wedge something against the thin housing as I think the service manual suggested.
