OK, here is the Wix Filter Iam using part# 33393. It is a short spin-on.

The Racor Filter Assy Iam using is a 200FG. It is an older unit and don`t think they are being made today, but I have pulled a few in the PNP type Junk Yards. seen mostly on 80`s MB Diesels. Not a lot, but they do show up once in a while.

My 80 MB 240D came with one, how ever it was disconnected and they went back to the small plastic Pre-Filter. Sort of like they use on these Datsun/Nissan SD engines.

Seems like a joke with just a mesh screen in it.
I had to disassemble the Racor and wash out all the gunk, looked like old engine oil. replace the rubber fuel lines, and works good. amazing what sometimes is in the bottom of the bowel.

I ran into the same problem on my 720 running biodiesel. See this post.

main shaft kit# 9951 and $19.49 and the Counter shaft kit# 14932 and $23.77.

Careful there, as the CS bearing comes in two different diameters, depending upon the year of the bellhousing. The later one is larger. They are a high-failure item on the trans.

Yes I know of the two different sizes, 56mm on the earlier trans up to late 84. Then it was enlarged to the 62mm bearing.

I just ordered the two front bearings, Input shaft and Counter Shaft bearings for this new 83 long bed PU with the SD-25 engine.

Been doing some e-mailing and phone calling with VXB. the Kit# 14932 is a sealed bearing. they didn`t show the open bearing. so they did some searching and located the bearing. it is kit# 19212.

It is now listed on their web site. :>)

VXB is one top notch CO., they will bend over backwards to help get you what you need. the customer service is #1

Counter Shaft bearing 63/22x c3 56x16x22
Kit# 19212 open bearing. $23.77

Main shaft bearing with snap ring 30x72x19
Kit# 9951 open bearing w/ snap ring. $19.49

The only difference between a sealed and open bearing is the metal or rubber side covers. they can be removed, and it is the same bearing.
The main shaft bearing I have coming is a sealed one, but they are removing the covers. think this is maybe their last one in stock. They did a lot of searching just to find it.

VXP at the moment is out of the Main Shaft bearing and will not be any until sometime in Jan 2014.
When my order came in on Thursday, only the counter shaft one was in the package, the main shaft was listed as BO.

I went on Google and e-bay searching for a bearing. more or less came up empty handed. but did find this site up in Canada. it is the sister CO. to VXP in Anaheim, Ca.

So my main shaft brng should be here around Tues, along with my new clutch assy.

This next week will be R&Ring the eng/trans.

I like VXB, I've used them for several odd bearings that I didn't need right away, but I don't think the FS5W71's bearings are all that special -- couldn't I buy them from FAG or Timken or whatnot? The retainer ring groove may be a hindrance, I suppose. I've not looked into this in quite a while.

[later]
Yup, over in my Dec2005 post on using a donor gasser's transmission in my '82 720 SD, I posted these part Nos. and (2005) prices:

BCA 306-LO $71.02
BCA 204 13.40
NTN 63/22 $90
Extension housing bushing $16

I don't know if I posted info on which of those four part Nos. are for just the two front bearings, but it wouldn't be hard to run that info down.

All I'm saying is that you are not limited to VXB for these bearings. If you're looking for the best price, then maybe waiting is worth it, but I'm not price sensitive when it comes to ball bearings -- in a trans, I want the best bang for the buck, and the top five brg manufacturers all cost about the same, last time I looked at them.

Years ago, I believe that someone was taking early front cases like ours and boring them to accept the 62mm OD bearing. I personally don't need that much torque capability (I think) but if turboing, yeah, maybe it'd be worth it in and SD application.

I originally went to Santa Cruz Auto parts which now is CARQUEST. The bearings the were able to get are Chinese bearings. They got the input shaft and the two on the rear main shaft and counter shaft. They could not cross reference the front counter shaft bearing. so ordered it from the dealer for $42. the 3 from Carquest were $87.

I then started looking around and found VXP and got the Japanese Nachi bearings. main shaft and the 2 on the rear for $33 with shipping.

The BCA 306-LO is the main shaft
The NTN 63/22 would be the counter shaft.

VXP just seemed to have the best price, and went the extra mile to find the parts for me. and I get them in a few days.

A lot of these major name brand bearings are now being in made China and else where with the brand name label. They may be good, I just don`t trust their quality control.

I ordered a SKF and a FAG pilot bearing for a Mercedes. both now made in Argentina.

I was just reading through your Transmission thread last night.

After perusing Craigslist for a good sd23 or sd25 for the last few months, I haven't found anything affordable within driving range of Oregon. Some people had fair prices, but too far away, others were just too proud of their "stuff." A SD22 left outside for three years "that just needed rings" is not worth $1000. Just sayin... So it looks like I'm going to "plan D": fix the existing motor.

I should mention that I don't know what I'm doing. I'm hoping those who know better will pipe in when I'm screwing something up!

I ordered a compression gauge last night so I can get an idea of what I have before I pull the head. After pulling the head and inspecting it and the pistons, Ill have an idea of how big of a mistake I'm making.

First question: I saw on another thread (don't remember where) that you can use a SD23 head gasket on the SD22. Based on pics of the SD23 on Ebay, it looks much stouter than the SD22 gasket. Does anyone know if this is true?

Thanks, Duane

Where exactly do you live, Oregon, Washington, Canada?
In the Portland/Vancouver WA area, they do want quite a bit for their Datsun/Nissan diesel trucks, I do believe that I have a re-buildable block out back, it just depends on your location.
PM me

#39

Im in Medford. Is your block a SD25?

The rebuildable block is a SD22, it is just a block with main caps, don't know if it has rods, and it has no head.
SD25s are kinda hard to find, I have found mine in some strange places, the first SD25 I ever found was on the side of some guys house laying in the mud, and it's a great engine, I happened to see a 4wd 620 at one of my customers houses, I stopped and talked to the guy about his truck, I mentioned that I had diesels, and he said he had one that he was selling, I asked him how much he wanted, went and looked at it, surprise, it was a SD25.
I paid $320.00 for the engine, transmission, a set of gauges, and some other stuff, he just kept coming out of the garage with parts and throwing them in my truck, BTW it had a home made turbocharger on it, I took it off because the waste gate was wired shut, so it did not work correctly anyway.

Eliminero67, Look in the peddle and procure it forum section, I post SD22, SD25, SD33 and other Nissan parts, trucks etc./.. I run across on CL. maybe something will show up.

The SD25 is a rare one for sure. I just bought an 83 720 long bed, first one I have run across. There were more of the SD22s sold for sure.

Ya gotta just keep looking. I agree, some of these people think their old rusted out junk is Gold Plated. Remember, it is all old 30yr old rusty, neglected, mistreated, and I don't care what the seller says about how wonderful it is.

If it has been run on WVO or??? I pass on it, actually run away fast. :>O

Will keep an eye on the peddle or procure section, and I'm with you on the WVO. Just cause something will run on it, doesn't mean it is good for the motor.

btw, appreciate the offer, but not really looking for a SD22.

JDM advertises sd23 motors at a pretty good price. If I didn't just dump all my $ in my DD I would just call JDM and get a SD23 for $1400.

Thanks for the help and keeping an eye out-something will show up!

After perusing Craigslist and the internet for months for a new motor, I decided to pull the head of the existing sd22 to see why it is blowing so much smoke.

I don't know if I mentioned it before, but I'm not a mechanic...going inside a diesel is new to me. Fortunately the SD22 is about as low maintenance as a motor can be! If anyone sees that I'm doing something wrong, I'm always open to ideas or suggestions.

I have to say, early Nissan/Datsun vehicles are well engineered and well built. All of the bolts and parts are easy to access, and I didn't have any trouble except on the very rear nut of the manifold, which was not accessible as I had to put the motor as tight to the firewall as possible to make everything else work. To compound it, It was not possible to remove the exhaust as it is tight against the steering box. Long story short. I had to remove it as an assembly. Just something to think about if you swap an SD motor into another vehicle-make sure you can get at the places you need to without removing the entire motor!

I don't have the shop manual, but I hope I can find the #s I need to check on the internet.

#44

Found this Datsun 720 (FSM) shop manual on E-Bay. I have this same one, bought it back in 81 when I bought the truck. Has the Diesel engine info in it.

http://www.ebay.com/itm/1982-Datsun-Pic ... 17&vxp=mtr

Be sure to contact the seller to make sure it has the Diesel info in it.

If you eventually come across a SD-25 engine, the 83 Nissan FSM manual has the info for that engine. I bought this manual a few years ago thinking, well ya never know when an 83 might just show up. and now I have an 83 :>))

I picked up an 86 manual also.

The whole time I've been working on this, I kept hearing an old friend's voice: His favorite expression was that "there's never time to do it right the first time, but always time to fix it later."

and he's right.

I had removed the head, cleaned 30 years of &^%$! from it. Inspected and reground the valves and seats. After doing this manually, I was REAL glad that the SD's only had 8 valves! Everything was going well, three of the valves had some pitting, but they cleaned up and after removing all of the carbon build-up, sat in the seats pretty well.

I moved on to the cylinders. There was no pitting on the walls, but they are worn. They are still within specs, but barely. The right thing to do is pull the motor and have them rebored.

That's when I realized that doing this right is going to get expensive quick. I added up the cost of a rebuild kit, machining and tools, as well as my time, and...
ordered a SD22 from JDM motors.

I had considered this earlier, but after talking with one of their representatives on the phone, did not feel comfortable dealing with them as they, frankly, seemed a little shady.

stay tuned....
