Ron1200 Posted August 5, 2014 Report Share Posted August 5, 2014 I'm changing my engine from a L16 to the L20b. While Its out I thought I'd change the clutch. With this menagerie of parts, do I need to spec out each component individually or can I just buy a kit (pressure plate, disc, throw-out bearing, pilot bearing)? It looks like a kit from a 610 (200 mm) might work. Any recommendations? Quote Link to comment
tr8er Posted August 5, 2014 Report Share Posted August 5, 2014 You will be faced with the question of weather or not you want the roadster clutch. 200mm like the 620, but much higher clamping strength. Most people who seek out the 200mm are additionally shopping for the roadster clutch. $$, but spins tires well. The truck clutch is likely much more than any daily will want from what I've read. ( I'm shopping for the exact same stuff right now). And it's less than half the price from what I've found. Quote Link to comment
datzenmike Posted August 5, 2014 Report Share Posted August 5, 2014 If you have a 200mm flywheel it's from a car L20B and not used on a truck. Trucks use a 225mm flywheel and that would stand up better than just a usual car 200mm pressure plate and disc. If you are buying a new clutch anyway try to locate a 225mm flywheel and match a truck 225mm clutch to that Quote Link to comment
Ron1200 Posted August 5, 2014 Author Report Share Posted August 5, 2014 I don't tow or carry heavy loads with the 620. It's really used more like a car. Seems to me that the 225mm flywheels are hard to find and I already have the 200mm one torqued on. This was the kit I was looking at:http://www.rockauto.com/catalog/moreinfo.php?pk=2392898&cc=1210071 Quote Link to comment
banzai510(hainz) Posted August 5, 2014 Report Share Posted August 5, 2014 what is a 6008 listed as????? I just got a stock daiken/exedy 6020 i think for my 521 which is same as 510. and I needs to use the 510 t/o bearing and sleeve. 6008 listed for what vehicle. I know soem 200mm pressureplates had a different diapram height like the 79 200sx and is a 200mm but it is different. and coul cause T/O bearing issie or slave cylinder rod lentgh issues. I myself stock with the 510 throwout fork and used the 510 slave cylinder and adjustable rod. when switch to my 200sx 5 speed Quote Link to comment
Ron1200 Posted August 5, 2014 Author Report Share Posted August 5, 2014 Among others, the 06008 fits the following 2.0Ls 76 610, 77 710, 79 510. Your right, On Rock auto the 06008 kit also fits the 79 200sx. Quote Link to comment
banzai510(hainz) Posted August 6, 2014 Report Share Posted August 6, 2014 I assume youll need the Colloar for that model issued 79200sx collar Most of us use the 510 clutch(stock weak 350kg) or the Roadster(650kg) set up as the diaphragm height is the same to keep it simple and we already use the 68-72 510 set up the otherwht your using is a 450KG I think but not positive just watch the rod length issue with the slave cylinder Quote Link to comment
Ron1200 Posted August 6, 2014 Author Report Share Posted August 6, 2014 I've been doing some research... Just for perspective... I've been looking at 225mm flywheels. They are not as expensive or unavailable as I thought. I can get a new one for $54, including shipping. The 70 2000 Roadster 200mm pressure plate I found was way too expensive at $399. So I can get the 225mm clutch kit and flywheel for $131. So is there a TECHNIQUE in changing a flywheel. I now have the engine on a stand and it blocks access to the flywheel bolts. I'm afraid that if I try to change the flywheel while on the hoist (bolts at 109 ft lbs), I'll break the studs that holds the slinger brackets. Keep in mind that I'm doing this by myself.

Eomund Posted August 6, 2014 Report Share Posted August 6, 2014 You'll want an impact wrench as the bolts that hold the flywheel are a bitch to get loose otherwise. And to place a new flywheel on, you will want to use a clutch centering tool so it goes right where it needs too. Might recommend using some Blue locktite (the breakable stuff) just for some added security on the bolts as well. Quote Link to comment
banzai510(hainz) Posted August 6, 2014 Report Share Posted August 6, 2014 I think I had a stack of 225mm flywheels and ted down south(360 951 6250) by you should have some of them also.As I might of gave mine to him. Russel at Nissan tacoma i think call him on the Roadster pressure plate 1866 754 5500 or 1800 9271831 have the part number and make sure its in stock. 399 is to much. you could just buy a 620 truck set up and call it good.make sure to use the 620 collar. from daiken importrp.com as for tighten the crank bolt i got this from daniel I think I made a LONG bar(alum angle stock)slightly oversize the holes and used the pressure plate holes to screw it in. then lower the engine hoist till motor was close to the floor. the bar is long enough to hit floor and since I used the offest hole so I can get to the crabk bolts and then move bar to the other holes. Or mabe use a breaker bar up from on crank jam under the hoist leg Quote Link to comment
DanielC Posted August 6, 2014 Report Share Posted August 6, 2014 I think I am the Daniel Banzi510 is referring to. Flywheel bolt removal. Same method can also be used to torque flywheel bolts Quote Link to comment
Eomund Posted August 6, 2014 Report Share Posted August 6, 2014 Something like that can work. My Dad had to do that for his Z when he pulled it a we didn't have an impact wrench yet. Just be careful not to scratch the flywheel surface. Quote Link to comment
Ron1200 Posted August 6, 2014 Author Report Share Posted August 6, 2014 Hey thanks for the tips guys! Hainz, If it's the same Russell that I've dealt with, he is at NissanParts.cc here in Olympia. I've just left him a VM. BTW... Their on-line price for the Roadster clutch (30210-20111) is $396.13. Dealer msrp is $476.35. And I found one at datsunparts.com for $299.00.. Ouch!

Eomund Posted August 6, 2014 Report Share Posted August 6, 2014 If you go for a larger flywheel. You can do What I did and go for an Exedy stage 1 organic. W/out the flywheel, you get the clutch, pressure plate, throw out bearing and pilot bushing for about $375 (unless prices have gone up in a year). I've been running, torturing even, the same clutch on my 240sx for 6 years and it's still grabbing strong. I will warn you, the pressure plate is pretty stiff as the clutch throw is on the short side. But it'll be strong and reliable. Oh, and to note, more than the 2.0L had the larger flywheel. I gnabbed mine off an old 280z motor from one of my Dads old cars. Had it re-surfaced and bolted up beautifully. Quote Link to comment
Ron1200 Posted August 6, 2014 Author Report Share Posted August 6, 2014 Thx From what I've found on the interweb (so this may be full of crap), there are 200, 225, 241 mm flywheels out there that will fit on a L20b. The 241 was from a 280z(x?) 2+2. Quote Link to comment
banzai510(hainz) Posted August 6, 2014 Report Share Posted August 6, 2014 Yes there were 240mm fW from the 280zx 2+2. trucks As Eomund stated about the 225mm Exedy stage 1 which I was going to mention but I think this is about a 750KG clutch. Be honest if this is a daily driver I dont think its needed and would go with a stock 620 kit(just my opinion) But the more stage 1 kits you buy hopefull they make more. I got 2 spares RoadstersPP at home and I think i paid under 100 bucks for each. disc and T/Os are cheap. I had a SPEC clutch kit(225$ 5yrs ago) in my 521 and the pretty hard pedal was hard but the disc fell apart in June and I stuck a stock Daiken back in as this is a daily and didnt need extra clamping. Be honest the disc was made in Korea but I notice the fingers were worn really bad and the slave was adjusted and also the wear was off center. so maybe my main bearing in trans is worn or soemthing. I wont buy a SPEC again. Knowing what I know now if i ever do it again(high Power L motor) I would get a alum 620 Flywheel to take adv of the 22mm surfave and the Exedy stage 1 pressure as its more than a roadster. Of coase I would need the T/O bearing and the 620 lentgh sleeve Quote Link to comment
datzenmike Posted August 6, 2014 Report Share Posted August 6, 2014 And to place a new flywheel on, you will want to use a clutch centering tool so it goes right where it needs too. Might recommend using some Blue locktite (the breakable stuff) just for some added security on the bolts as well. Clutch centering tool will do nothing to center the flywheel. The flywheel slips over the end of the crankshaft and this centers it. Quote Link to comment
Ryan Family 510 Posted August 11, 2014 Report Share Posted August 11, 2014 I'm in a similar situation. 69 510 which will now have an L20b and I also will be looking for a 6 bolt flywheel, clutch, etc. I am running the stock 510 4 speed as it is in really good shape. I was planning on researching a truck that came stock with the l20b and ordering the set up for that. Seems to be the easiest and cheapest. Any thoughts? Should all bolt right on, correct?

banzai510(hainz) Posted August 11, 2014 Report Share Posted August 11, 2014 Ryan you go to tell us the size of the flywheel. if a 200mm flywheel from a 200sx then all the 510 stuff will work. most put a Roadster PP in or the stock 510 PP. if going to a 620 truck youll buy the 620 set up but need the 620 T/O sleeve. Quote Link to comment
Ryan Family 510 Posted August 11, 2014 Report Share Posted August 11, 2014 I don't have a flywheel. I was considering the 620 package. But maybe I got 200sx if I can use stock 510 clutch and plate Quote Link to comment
datzenmike Posted August 11, 2014 Report Share Posted August 11, 2014 The L flywheels all look the same and generally they are. When someone says a 200mm or a 225mm and even a 240mm flywheel they mean the bolt pattern that holds these three different diameter pressure plates onto it. If not sure what you have just simply measure across the clutch disc contact surface. This one I have happens to be a 240mm but there are 225mm and 200mm. What ever you pick, the clutch / PP and the release bearing collar must match it. Quote Link to comment
Ryan Family 510 Posted August 12, 2014 Report Share Posted August 12, 2014 What year 200sx should I be looming for? Quote Link to comment
Ryan Family 510 Posted August 12, 2014 Report Share Posted August 12, 2014 Thanks you guys. Great info. My l20b did not come with a flywheel and as I researched I knew the flywheel for the 1.6 would not work. I appreciate the info and will start looking for a wheel and clutch/ pp that match. I will probably run the 200sx and stock 510 clutch kit. Quote Link to comment
datzenmike Posted August 12, 2014 Report Share Posted August 12, 2014 I will probably run the 200sx and stock 510 clutch kit. I wouldn't do that. The stock 510 clutch is made for the L16 and you now have an L20B with much more power and torque. PL510 and 610................................................ PP #30210-23000 is rated at about 350 kilos of clamping force. All L16/L18 620 trucks and all S10 200sx........ PP #30210-K0400 is rated at about 440 kilos All L20B 710..................................................... PP #30210-S0100 is rated at 450 kilos Seems to me the 710 one has much more grip Quote Link to comment
Ryan Family 510 Posted August 12, 2014 Report Share Posted August 12, 2014 Who am I to argue with the king rat! Again, thanks for the input, I really appreciate it. Looks like I will search for the 710 flywheel and related clutch parts. Stay tuned! The L20b block and head are still at the day spa. Should get them back soon! Kevin Quote Link to comment
