How to take apart a Sachs 505 Clutch - Disassembly, Diagnosis, and Reassembly with Travis & Will

- I was always afraid to pull it apart, but it's really not all that bad - there are several write ups for this clutch on MA, but I have yet to see a video about it. Sachs makes a really nice motor.

Does this mean tutorials for sachs now? You're the best.
thank you SO much. this just helped me rebuild my 505/1A clutch and get it working again. such a god send!!!
Ahh what a cute clutch :-)
Never seen one like that before, good old atf, puch juice lol :-)
Your mate did a smashing job of repair and explained every part, nice to see someone still takes interest in repairing things.
Now time for swarfega for the hands and a cup of coffee to slurp lol :-)
I had a 125cc bike that had a slipping clutch, dissasembly and clean/re-assemble fixed the problem, im sure it just wanted to be fondled to make it happy again ha ha :-)
Nice vid Travis :-)
Oh man, I'm super afraid to do this but I'm so happy I have this video to follow along with. Thank you trav.
God bless you for doing this. This is god's work. I have to bust open my clutch this winter and I'm going to follow this video exactly to avoid any issues
Travis, you always have the answers to my questions.
Thanks for this video! I was having issues with my 504 clutch (which is the same) and need to replace the cable/block off the leaky decomp valve. Only worked on Tomos clutches before so when I popped the cover I had no idea what I was looking at, but this video helped a lot!
This was EXTREMELY helpful.
Only issue I see is the piston stop. I have read/heard this can seriously damage the piston.
Take a socket put it to the flywheel and then go to the clutch nut and y tighten it while holding the flywheel in place this will stop the pistion
Thank you guys so much. I bought a Sachs a while back and I've been sitting on it for a while working on my Maxi until recently and I got it running but the clutch seems to have died on me I have tons of spare parts that were never used but without the knowledge of what I'm doing I've been a bit wary of going in. I'll be getting back on it tonight!
Sachs is a real underdog, but they are fun in their own special way!
@@TravisTutorial Yeah I've been having some fun with it, the issue I had was I lost the spring that holds the arm level with the starter clutch. The only real issue I've been having is the cost and availability of some parts which is mostly not a problem because I have spares.
I couldn't find decent looking (or any) side covers and most of the groups would say you don't need them which wasn't helpful. I ended up just using my old ones for a reference and modelling my own to 3d print when my schedule clears up. I put up a short video showing some of the mess I've done/am doing pretty short if you're interested.
hell yea! this is rad.
i will say tho, check clutch preload is important. its easiest to measure with the stack together and outside the clutch and the springs not in. so you can measure the height and measure shim size needed.
ALSO YES USE LOCTITE! there's nothing holding your clutch to the crank besides that nut! and so on deceleration (especially doing sweet skids with the coasterbrake and more still with higher performance kitted bikes etc.) they DO spin off. I have seen it. alot.
What sites can i order parts from if i got a sachs .What are the top 3 things should i buy if i just got one of these? What type clutch and break handlbars should i upgrade too?
I am rebuilding a badly seized Foxi GT with a Sachs 504. I mean seized like I had to cut the jug and piston off 😕 This video will help me as I work on the rebuild. Thanks!
Oh wow! Yeah you have limited options since the head and cylinder are one piece I've heard of people having to do that - glad it was helpful best of luck with your project!
Hey Travis, I have an issue, My Eagle III 505d moped starts, run and idles fine, but when I get on it and hit the throttle it dies. I have replace the clutch pads and rebuilt the clutch, sent to shop and no one an fix it. I am starting to think it's more of an electrical issue. As the headlights don't work. Could the kickstand or brakes cause issues with the clutch not engaging properly
This clutch is definitely just misunderstood. That is a really simple and reliable setup.
does the bevel on that gear face in or out?i noticed 1 side has a bevel and one side does not.
Is there any way to drain the transmission fluid?
hey man. I am trying to find a website that has all the parts for sachs 505 motor. and also trying to find the cables for the entire bike. its the Hercules 505. do you have any places I can look that wouldn't have them out of stock?
Plenty of German Websites have loads of parts for the 505 for example disa-mopedstore.de
I have a g3 with 505 D - I also bought a minarelli v1 engine. Now I'm starting to think its best to keep the 505 D over the minarelli. I se you guys are rocking both. How hard was it to mount the V1? is it really one additional bolt?
It all depends what you'd like out of the motor. A 505D motor is 2.7 horsepower stock which is pretty neat. Basically, if you're interested in kitting and want an easy selection of aftermarket parts a V1 will satisfy, but if you're fixing a stock bike or maybe just planning on putting a pipe that Sachs motor will be plenty reliable.
If you end up doing the swap there are the normal considerations - changing the gearing, fabbing mounts, making sure the chain lines up, carb/intake clears frame, etc. The V1 bike shown was a factory bike, since General peds came with both motors I can't imagine they're that different.
What type of carb do you have?
Id change the float, needle, and gasket in the carb and make sure the jets are clear.
Question Travis, I have a Grycner Floozie (AKA General 5-star ST) it comes with this super crappy conventional battery that needs acid to work (6v 4.2 AH), Do you know any good replacement batteries? Preferably a maintenance free.
I actually just bought a bunch of parts off of a Grycner Palm Springs (pretty much the same thing)!
I remember at one point trying to look for a conventional "car" type battery and wasn't successful. You can however, find compatible batteries that take distilled water and not battery acid, so that's nice.
TravisTutorial I know the exact model, It would be amazing if you did a video on it ;).
Also, I couldn't help to notice your filter, I know treats has the OG filter that fits perfect, but do you know any others that might fit? Also, do you know the size? Thanks a bunch
Kevin Salas I wish I could, I was buying front end parts for my Clinton 50-a (same body style). As for the air filter, honestly that Treats filter is probably the best bet. I ended up rigging some window insulation that worked well, but for a direct fit that's the ticket, the sizing is a little goofy.
I have the same moped, but I have a problem with it. After using it for like 10 minutes the motor startes to have less power and a acceleration, and when I come to a stop its like the motor is having a hard time to stay on. I have played with the carb and that was not the problem. Can u plz help me?!
what size is the puller for the mag need to take off the flywheel
Unfortunately answer is not quite straight forward, Sachs 504 and 505 use a different size flywheel:
www.myronsmopeds.com/category/ignition/bosch/
Biggest difference, Sachs 504 pedals are outside, 505 pedals are inside. Treats sells a flywheel puller that works on a lot of Sachs, but not all as the description says so be careful. www.treatland.tv/puch-bosch-flywheel-puller-p/puch-bosch-flywheel-puller.htm
What carburetor is that? I got an old Columbia 1976 that has the same or similar Sachs on it that. Someone before me, put a Bing carburetor on. It runs but, way too lean! I can't use full throttle and I'm worried about damaging the engine.
It is a square bing, you can read a little about it here:
www.mopedarmy.com/wiki/Bing#Bing_.28Sachs.29_Carburetor_Diagram
To be honest, I'm not the biggest fan of it, but on a stock bike it's a fine carb. I assume you're referring to a round style bing someone put on there, which is actually very tuneable. If the bike has been modded (air filter removed, or a home made exhaust pipe put on...) then you'll need to swap out the main jet in that round bing for a larger one so it gets more fuel and isn't lean, assuming that is actually your problem.
TravisTutorial Yeah, it's a lean bog because, the spark plug is very chalky(even when I set the needle to the richest setting). I figured as much that the jet might be too small. Do you know any good places to get jet kits?
Oh, and thanks!
Lewis Veasey
No prob!

TravisTutorial You the man! Thanks, I'll make a gopro video if, I get it running right.
The "strange" scratches on the metal plates comes from the factory lapping. They're there to give some friction
I am happy to fix, tun and ride a Sachs 503. Seams much better designed than thi slittle nifty things of the 505.. Have fun!
Check out lovers of Sachs mopeds on Facebook. Lots of really smart helpfully people on there. And some good deals on mopeds too!! You won't get those dreaded "just buy a minarelli " responses when asking questions!!!!
hi im mathias from germany. i have a hercules m4 from 1977 with a sachs505A1 automatic motor. i have never seen this moped is it homemade :-D ?
Travis My rear wheel is locked up ...I watched your great video but I see my spring is on the top and yours is n the bottom????? I don't think my cover has ever been off. Is there a reason for this???? Thanks David
I've got a bing box carb. With no air filter
what about the cable. the clutch cable.
alimamy thollie have any luck? I’m trying to instal a new cable now and having kinda a bitch of a time
The grooves are from driving with a worn out pad.
honestly kinda sounds like your clutch is slipping, overheating and expanding.
if you went through this very tutorial on your bike it'll prevent your clutches from slipping and overheating which causes them to then stick and kill the bike especially when coming to a stop.
