Flywheel Part #?

[dieseldorf]

I searched everywhere, I could not locate a used flywheel for the manual transmission. Car-part.com does not update their inventory database. None of the listed flywheels were available. I have no other choice than buy a new one from nismo parts, if they still carry it.
What is the correct part # for that flywheel?
I am going to use the 4-speed tranny from a 720 pick-up. Possibly upgrade later to a 5-speed from a 280 ZX.

I will look up that number when I get home (where the parts manual is). You may want to attempt to do it yourself, using Nissan FAST, a frustrating experience but sometimes profitable. You will likely need to do more parts lookup in the future, so you may as well familiarize yourself with it. See this thread.

Try to avoid starting a new thread for stuff like this: you already have at least one other thread on this exact same topic. Best to add on to an existing thread, than to start a new one. OK?

I added the MT flywheel part Nos. to a previous post on AT flywheel/flexplates/driveplates.

[dieseldorf]

After 10 days waiting I got a response from nismoparts.com:
flywheel for the LD28 with manual transmission NLA!

Hi There,
How much do you want one? I might be able to track one down here in NZ, but shipping costs might be a killer. I will figure out how much one weighs and see if it can be posted.

bp, I have to ask. How common is the LD28 there in NZ? Web searches for the LD28 often seems to lead me to NZ. I've seen ads from NZ for older 1/2 ton pickups with an LD28 under the hood, but no pics from under the hood. I'm very interested in any info on swapping an LD28 into a non Nissan chassis.

(If this gains any momentum, I'll split it out to a different thread or continue the discussion in another existing thread so as not to hijack.)

Finally I could locate a used flywheel with car-parts.com
First I was skeptic but the seller assured me that it was from a Diesel sedan with manual transmission.
Thanks for your offer bp from NZ.

[asavage]

What are you ending up having to pay for it (cost + shipping)?

[dieseldorf]

The flywheel was $35.00 and shipping $25.00 Shipping is low for the weight, so I am still skeptic whether it is a diesel MT flywheel. I do not have it yet.
I will report once I get it.

[dieseldorf]

I got the parts today. Some lightweight flywheel. It is definitely from a Diesel engine. The tag says 1981 5 Door Maxima Diesel sedan. All the parts weigh only 12 LBS! That is less than from a gasser ( 280ZX). The flywheel itself is only 10.5" in diameter.
The clutch plate and disk I have (from a 280ZX) are bigger. Now I have to look for a new one.

The tag was Maxima M.T. Diesel, not 5 door sedan. 5 door would be wagon which did not come with a 5-speed M.T.
Autozone.com is listing a ring gear PN: FRG-105G for $27.99 and has it in stock. What is a ring gear good for?

Autozone.com is listing a ring gear PN: FRG-105G for $27.99 and has it in stock. What is a ring gear good for?

Ring gear: on many flywheels, the ring gear can be replaced. The usual reason is that someone didn't keep their engine in good condition, overused the starter, and wore out some teeth. Most engines tend to stop in exactly the same spot, so the same teeth take all the abuse of initial starter bendix gear engagement.

I've not heard of the LD28 flywheel teeth getting this bad yet, but I'm sure someone has worn theirs out.

I've replaced the flywheel ring gear a few times, most recently on my now-sold 1984 F250 diesel:

Note that it's very uncommon to be able to replace the ring gear on AT-equipped parts, as the ring gear is almost always welded on (as in yours, in the picture you displayed above). The Ford 6.9l ring gear I show above is for a C6 AT, which is one of the exceptions: IH used the same ring gear for both AT and MT flywheels, and they can be pressed on in both cases. I do not know of another example where this is the case. The general rule for light-duty stuff is: ring gear replacement is possible only on MT flywheels.



I am sorry to inform you that you have received the AT drive plate and flywheel, instead of the MT one. In the screenshot from Nissan FAST below, the AT parts are shown in the lower right corner ("ATM"):

Al, you're right. Those idiots sold me an AT plate instead. Another $60.00 waisted. I am really frustrated now. This flywheel-clutch issue is holding me back for a month already. I have that flywheel (and clutch set) from a 280ZX. The only difference is the ring gear and weight. Maybe I could shave off the old one and install that from the AT plate or from Autozone. What do you think Al?

[asavage]

I can't recommend it. You will not be happy with a light flywheel on the diesel. BTDT and it was horrible (not on an LD28). You'll also beat up the starter without the mass. I'm sorry that I don't have a good solution for you, but using the gasser stuff really isn't it.

I can't believe it's this difficult to find an LD28 MT flywheel!

Union Auto Wreckers USA-NJ(Union) doesn't have one? They're in car-part.com, and it says diesel specifically. Or is that the one you just bought?

LD28's are a dime a dozen down here due to our relaxed importing laws that allow millions of laurels etc with the LD28's in them - have a look at this site http://www.trademe.co.nz/Browse/SearchR ... ype=Search and you will see what I mean
