RacnJsn95 Posted November 19, 2007 Report Share Posted November 19, 2007 I know most nissan cranks have some numbers cast into them, for ID purposes I guess? V07 comes to mind for the LD28 crank. So, would anyone happen to know the number for a z22 crank? I was finally able to contact the guy with the ad on craigslist with the "l20b" and "Z22" crank, but it turns out he's not sure what they are... The L20b crank mentioned in the ad, he says is actually an L18 crank, and he's sure of it. He says he thinks the Z22 crank is a Z22 because his friend told him. So, anyone have a z22 crank to pull numbers off of? Hang510? Quote Link to comment
datzenmike Posted November 19, 2007 Report Share Posted November 19, 2007 The L16/18/20B/ Z20 is fully counterweighted, the Z22/24 is not. Here is a Z22 and an L20B crank. Note that the L20B has extra counterweights on it, or, the Z22 is missing them. The extra weights help it to run smoother when revved higher. http://i138.photobucket.com/albums/q251/datzenmike/00270019.jpg[/img]"] Where are the numbers located on it?, never noticed them. If they are like L heads there might be several numbers. I'd go with the crank throws. Quote Link to comment
RacnJsn95 Posted November 19, 2007 Author Report Share Posted November 19, 2007 The numbers are usually located on one of the counter balances... The numbers are right in your picture... I adjusted the brightness and contrast to make it a little more visable... I can't quite make out the last character... U6-something. I'd assume it was from an L20b. I can ask him to send me a picture and that would narrow it down to being a z22/z24 crank, or not... But I can't use a Z24, so I need to get the numbers... I would rather not ask a complete stranger to try and measure it for me. http://i12.ebayimg.com/02/i/000/c4/bd/49eb_1_sbl.JPG This picture shows the V07 on an Ld28 counter balance.

datsunaholic Posted November 19, 2007 Report Share Posted November 19, 2007 Most, but not all, L20B cranks have a U60 cast on them. All L20B cranks up to '78 do. L20B cranks are 8-counterweight cranks. Z22 are 4 counterweight. And an L18 crank would be really obvious... only 5 bolt holes on the flywheel flange, vs 6 on an L20B. Quote Link to comment
RacnJsn95 Posted November 19, 2007 Author Report Share Posted November 19, 2007 So would it be safe to assume that all nissan/datsun cranks '78 and newer have a number cast on them? Since the Z22 was 81-83 only, I would think that it would have a number also. Maybe I'll just ask the guy to send me a picture of the crank if he is able too, and just hope it's not a Z24 crank...

datzenmike Posted November 19, 2007 Report Share Posted November 19, 2007 If I could find my crank, I could look at it. I've got a Z22 and a Z24, they might, or might not have some numbers on them. Now that I think of it, I might have a Z20 crank too. Looks just like the L20B. Quote Link to comment
hang_510 Posted November 19, 2007 Report Share Posted November 19, 2007 ill look tommrow at:L18, L20b, Z22(X2) not all L16's are fully counterweighted. Quote Link to comment
datsunaholic Posted November 19, 2007 Report Share Posted November 19, 2007 I'm pretty sure that ALL Nissan factory cranks have a number cast on them... Nissan was pretty good at putting casting numbers on just about every major cast or forged part. Quote Link to comment

datzenmike Posted November 20, 2007 Report Share Posted November 20, 2007 Z22 crank from top to bottom JAPAN 1-1 30W40 30W Z24 top to bottom 6-2 06 (in this relation to 16-2, unless upside down 90) Quote Link to comment
RacnJsn95 Posted November 20, 2007 Author Report Share Posted November 20, 2007 Well I did a little searching last night, and came up with a possible z22 crank number, which was M90. I emailed the guy with that z22 crank on ebay, asked him, and he also gave me the M90. I'll assume M90 is a good number for the Z22. Thanks for looking at your crank(s) Mike! So I called the guy back tonight, and told him to look for M90, 30W, or 30W40. He's supposed to call me back in a while... I'm still interested to see what yours says Hang510. That would be cool if it's 30w, which could confirm a second z22 crank number. Quote Link to comment
hang_510 Posted November 20, 2007 Report Share Posted November 20, 2007 M90 :confused: turn it over :lol: i have a 06W its on the #4 and a 21-0 on the #2. this is on the installed Z22 block so i know its stock. didnt make it to the other to look. Quote Link to comment
hang_510 Posted November 20, 2007 Report Share Posted November 20, 2007 oppotunity knockin...http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&ih=005&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=150184518933&rd=1 maybe im upside down :o in the description, its say M90 Quote Link to comment
RacnJsn95 Posted November 20, 2007 Author Report Share Posted November 20, 2007 Another for M90! or 06W ;) Why don't we turn this into a tech thread? Amoung my searching I've found lots of other people asking the same question as this, but no one ever answers. If anyone has any cranks laying around easily accessable, why not list the casting numbers here? I checked my 240z crank last night, and it's got E3141 on it... (E31 is cast into most 240z stuff I've seen like manifolds, etc.) Quote Link to comment
RacnJsn95 Posted November 22, 2007 Author Report Share Posted November 22, 2007 Well the guy called me back today... One crank has a U60, and the other has a U67... I bet their both L20b cranks. That's too bad... Quote Link to comment
Fineline Posted November 23, 2007 Report Share Posted November 23, 2007 I dont know if this helps but here is a pic of my Z-22 crank installed. Unless my eyes decieve me I believe thats an M-90 by the #4 journal? The pans on it now so I cant check it again. Sorry. Have the guy send you pics of the cranks side by side. Looks pretty easy to tell the diff between the two. Quote Link to comment
datzenmike Posted November 24, 2007 Report Share Posted November 24, 2007 Well the guy called me back today... One crank has a U60, and the other has a U67... I bet their both L20b cranks. That's too bad... Tell him to send a picture. The Z22/24 has 4 counterweights the L20B has 8, a big difference. Check the first picture. Numbers or not... I would measure the rod to mains center line distance to be sure. Quote Link to comment
