A 521 in Massachusetts

Recommended Posts

521 body parts are measured in inches.  The grease (Zerk) fitting is probably just a standard one that will fit almost any American car built before 1980.

All body bolts on a 521 are SAE.  Brake lines too.  Engine, transmission use metric fasteners.

 

My kudos to you guys working on 521 trucks on the east coast.  It is much easier to get 521 used parts on the side of the USA closest to Japan.

Ted took some off with a airgun and it dint take much to break those bolts off so that's why I said no way it could be that much torq.

 

the lower one I just put them on , No specs never had a proplem.

 

just grease those suckers a lot as you will wish you did.

The grease fittings in mine are 1/4-28..

And ya the torque is crazy.... found it in a few different books and online so it has to be right.... overkill if you ask me but I didn't design it....

So here's 2 other mods I have had to do.... first since the center bearing is hard to get I decided to see what the drive shaft shop could do.. they did a complete balance and over hall and i used a Volvo center bearing. ..

Came from a 98-00 Volvo v70/570

Part number 14850-50

It bolted to two holes that were already in the frame where the bearing original mounted... I still bolted the stock bracket around it just in case..

Oh here's a good part number. ... I think I've seen it posted somewhere else but I figured I'd post again... stock 521 crankshaft had a brass pilot bushing.. the six cylinder motors use a roller pilot bearing. Nissan part # 32202-09500 fits nice in the 4cyl L motors...

So here's my next mod... I got 620 motor mounts when I tried ordering new ones for a 521 with the l16.. so I decided to modify my mounts to except 620 motor and tranny mount easier to buy....

Next couple pics are the stock ones then I will post the 620..

My process was to install all the old stock mounts and one at a time cut the metal bracket to suit the 620 mount which was about half an inch taller... passenger side was a little harder. More stuff in the way... plus the oil filter wouldn't fit.

What I figured out is you can use a filter from a 95 Volvo 850...

The stock 521 s8 is 4.5 inches long

And s16 is a little shorter around 3.5

And what I went with was the Volvo one.

3 inches long i plan to use the Bosch 3321

Using an stps7328 because it was in stock and I am gonna change it after 500 miles anyhow....

Please ignore oil all over everything issue, I finally figured out the oil sensor was leaking thru the vent hole in it.

 

I am kinda curious here, why did you cut your engine mounts, I believe that I put late model 620 motor mounts in my 521 work truck and I just mounted the engine, I didn't have to modify/cut anything, my oil filter clears fine.

Maybe i missed something some where. At first i was gonna use a 510 mount. It was close but not perfect .. cutting the bracket wasnt my first choice but i couldnt figure another way.. Honesty yours look short compared to what i received.. I tried bolting things on and just wasn't even close... couldn't find anyone's post on motor mounts. So this is what a did... at least now they are cheap and easy to replace..

As I recall I used late model 620 mounts but maybe they were early 620 mounts, it was kinda a pain to mount them as I did it with the engine and everything else in place, but I got them in there.

Yes yours look taller than mine as I have a couple of them mounts in my motor mount box, I also have a few of the shorter ones I am using right now, and they are slightly shorter.

You need to raise your engine more, use thicker pieces of metal than you are using to get the engine high enough to use a normal oil filter, the bigger the filter the better, to me it looks like you cut to much of the passenger side mount off.

I really hate online sometimes. After Waynos comment I cross referenced a few numbers and it seems like the ones I used were for a 720. And it gets listed as a 521 mount... dea product a6353... I can't win.... well too late know....

I was wondering where I could have come up with 620 mounts like you have, now I understand as I have had a bunch of 720 motor mounts from parted out trucks I have saved that look like yours.

If you need another set of engine mount hardware like the ones you cut PM me.

I definitely didnt cut to much. the filter actually touched the mount... I kept the engine in a static location and modified one at a time so I know the engine wouldnt move and it stayed where it needs to be.. screw it. it's been cut and welded no going back.. at least I have a part number. .

No I bought these from rock auto and now they don't even list them... I crossed the Dea part number and amazon say it's for the 521 and the 720.. not correct for a 521 about half inch taller and i had to drill new bolt holes. they have them for the j motors and what they list for the l series seems wrong....

That engine is sitting low in there and tilted over an inch to the passenger side, maybe 2 inches past stock.

How close is the oil pan to the cross member?

How close is the oil pan to the steering center link?
