- Had the clutch slave cylinder gasket on my 1983 Honda Magna 750 go bad and start leaking. This shows the slave cylinder disassembly and reassembly as well as how to bleed a hydraulic clutch.
In case the bleeding process wasn't displayed well enough in the video here are the steps:
Pull clutch lever in as you crack open the bleed screw.
Close the bleed screw right before releasing the clutch lever.
Repeat this process until you have a steady stream of fluid and no more air bubbles come out of the bleeder screw.
This process is the same at the master cylinder.
Use the banjo bolt at the master cylinder the same way you use the bleeder screw at the slave cylinder.
Crack banjo bolt open as you pull the clutch lever in.
Close banjo bolt right before releasing the clutch lever.
Repeat this process until your clutch lever has nice and firm pressure when you pull it in.
If you have any further questions please leave them down in the comments and I will assist you as best I can.
One important thing missed was that the Clutch fluid line banjo bolts are supposed to be torqued to 25 to 35 nm which is 18 to 25 ft-lbs. This is per the Haynes reference manual for 1982 to 1988 V45 to V65 Magnas and Sabres page 2-9
Also, I believe you've confused the gasket that you replaced as the issue for the cause of the leak. There should have been no fluid in that area where the gasket is. That's only where the piston presses against the push rod. If you had fluid inside there, then the leak was caused by the piston seals being bad. You needed to replace the piston seals and to do that you needed to get the piston removed to get access to the piston seals for replacement. This information is described on page 2-30 of the Haynes manual for the 1982 to 1988 Magnas and Sabres.
If there is air in the high point by the master , just have a buddy help tip the bike to the right , away from the kickstand, pump the clutch a few times and it should work its way to the resovoir. No need to bleed it out by the banjo bolt . Enjoyed the vidoe , found during my frustrations this afternoon !
Yeah, I never thought about that. Of course I didn't have anyone around anyway, lol.
Good info man. Ive been fighting getting my clutch bled today.
Yeah, hopefully that does the trick for you. Took me a long time too, but once I bled the cylinder/reservoir it immediately was good. Be warned though, it is messy, and you don't want brake fluid on any paint or plastic obviously. So cover everything with rags and wash everything after.
Do you happen to know the exact slave cylinder mounting bolt thread pitch?
Unfortunately I don't since I don't own the bike anymore. However, if my memory's correct they were just standard 8mm bolts. So they should be M8x1.25 or 1.25mm pitch in other words.
@@mcmoto5424 ya know, that's the bolt pitch I bought, but one of em just isn't threading
Well the bolt closest to the rear wheel is a shorter bolt than the other two that are closer to the front wheel. The threads could be damaged as well so you may have to use a thread chaser or tap to clean them up.
