i'm looking through my haynes manual and it says to remove the timing belt to get to the seal.....i know i dont have a T-belt, but do i need to remove the timing chain?

 

Those instructions are for a VG equipped maxima. Not for the dohc timing chained VE you have.

No. timing chain removal is not necessary. Just remove the pass side tire, take off the plastic cover etc.. you will have to remove the front crank pulley to get at the seal.

 

shouldnt he take the oil out of his engine or not

 

This is of course a short version of the instructions but if the car is on a ramp, I don't think it's necessary. the seal is pretty far up the engine. ie.. higher than the top of the oil pan

 

Yeap, that's right. The seal is high enough on the engine that oil will not spill out when you take the old seal out. Pop the old one out with a flathead. And then evenly push the new one in. Be careful not to damage it.

I bought a new main oil seal at the dealer for like $3. And my mysterious oil leak suddenly stopped. And I got my new UDP installed.

To get that crank pulley off, an impact wrench is very nice to have. But, since you have a 5 spd, you can do without.

 

Got a 92SE and I need to change my front crank seal too but I have an auto. I don't have an impact wrench. Could you suggest an easy way to get the crank pully off? Thanks. - AC

 

If you try to take the crank pulley off with just a regular breaker bar, the motor will turn. You have to find a way to keep the motor from turning. I believe one way is to remove the starter and put a screw driver in the teeth to stop the motor from turning. I have never done this before. I think Matt gave me this idea.

When I did my UDP job, I was just about to take the starter off and do Matt's idea. And then my brother's neighbor said, "I have an impact wrench!" WooHoo!!! It took me about 2 seconds and that nut was off. And it took two more seconds to put that nut back on and torque it to 165 ft-lbs.

So, ask around and see if you can find someone with an air tank and an impact wrench, and all your problems will be solved. It will save you an hour of frustration. Since I don't know too much about that starter idea, I can't help you any further.

 

Thanks. Yeah, I think I'd better get an impact wrench. I screwed up many times before because I don't have an impact wrench.

do i absolutly need a torque wrench or do i tighten until i cant tighten anymore? i was planning to install the oil seal and pulley (ASP UDP+belts) but my unmotivated @$$ didnt get a pulley puller and the pulley still isnt here...

thanks for all the help

 

From what I am told, you do not have to have an impact wrench to get your pulley off. You just leave your engine in gear when you shut it off. I believe that will keep the engine from turning so you can use a freaking huge breaker bar to get that nut off. Since, I couldn't stop my engine from turning, I had to use an impact wrench. Have fun!

 

no, i mean do i need to have a torque wrench when i retighten the bolt or do i tighten until i cant anymore...? 165ft-lb is alot

 

Oh man, I'm sorry. Too many beers. I just tightened mine with the impact wrench. I tightened it until I knew it was not coming off. It's a pretty heavy duty nut, so I don't think you can bust it. There's no way my nut is coming loose. I think you can do 165 lbs with an 18" breaker bar. 165 is what ASP tells you to do.

 

The engine turns clockwise...you set postion for the break bar to break it loose turning left when you crank the engine for a split second. Works on perfectly without using strength.

 

The only problem I had was getting one belt off and on! I think the A/c belt maybe wrong but one of them I cut off and forced a new one on bike tire method

 

hmm..possibly pull the fuel pump fuse so the starter does all the work for me? this will be my last resort attempt..how about getting the nut back on?

 

oh yeah, what size nut is it? i suppose i'll need a heavy duty socket...

 

I would never dream of cranking my engine when I have a breaker bar attached. Don't do it.

As for the size of the socket, it's been a while since I did my job. I am guessing a 22mm socket. Just a guess though. I just used a regular Craftsman socket on an impact wrench. It worked fine for me.

Also, if you are having trouble removing some of the belts, make sure that tensioner is as far back as it will go. All my belts fell off. When I put the belts back on, I had that tensioner so far back, the belt easily laid up there and then I started tightening it. I followed my Chilton's Manual for belt removal. Good Luck!

 

I talked with a coworker today about this and he told me to check the nut to see if this is a right hand threaded or left hand threaded nut. He said the nut may need to be turned CW to loosen since he said this is the engine rotation direction. But from what I read here, to loosen the nut, you turn it CCW like a normal nut, is this correct? thanks.

Yeah, youre right...turn it CCW to loosen. Just like a normal nut. When I took off my pulley, I was wondering the same thing. I had an impact wrench in my hand and I didn't know if it was going to tighten it or loosen it. I took a chance and turned the nut CCW and it popped off. Some crank pulley nuts are CW to loosen. But, not ours.

 

Cool !!! Thanks man !!!
