Slave cylinder problems and boring a weep hole

Well if your about to change your slave cylinder on one of these beasts..before installing a new slave..bore a small weep hole in the slave cylinder housing (at the bottom of course) you'll need a 6 to 7 inch bit (10mm or smaller) clean out the swarf (pieces of metal left from drilling) from the housing, fit the new slave...this helps if the cylinder should fail again...the dot4 fluid will now run out the weep hole instead of being forced up the push rod....very handy..and remember replace the crush washers on the banjo bolts.

I need piston rings for 1991 7.3 IDI. What do they mean bore size Std., .020, .030, .040?


.20 .30 and .40 are oversizes. you have to measure the cleaned up bore to order the right ring set. if you are going to replace the rings you should get the cylinders bored and honed

QLink Frontrunner where do you change gear oil in rear end


Typically most gear drive motorcycles use the same type of system. There will be a small bolt either 8mm or 10mm or a Phillips head . That will be at the bottom of the gear case just below the rear axle. Remove the bolt and let it drain. There should be a smaller screw or bolt of some sort above the axle. That will be the " weep " hole. Once you finish emptying the gear box. You re install the drain plug and fill the gear box through the weep hole. You fill it til it starts to come out past the threads. That is the correct fluid amount. Re install the weep hole plug and you're good to go.

slave cylinder leaks


Remove the bolts holding the slave cylinder to the transmission. Disconnect the hydraulic hose. Reconnect hydraulic hose to new slave cylinder, and install the slave cylinder in it's original position.

Now proceed to bleed the line through the slave cylinder until a solid stream of fluid comes through, and the pedal pressure becomes firm.

how to install a slave cylinder on a 95 ford ranger


The easiest way to deal with this problem is to order the complete preblead slave cylinder kit.
You can, just go with a new slave cylinder but because of the age of the other parts. You may run into other problems down the road. Why have to do it twice.
To replace the slave cylinder only:
Its easy, just carefully push/remove the small metal pin that hold the plastic line to the slave cylinder. then push-in and turn counterclockwise, to remove slave cylinder. Then install new slave cylinder and reverse the procedure. Now bleeding the system will take a while. But all you will do is just keep pumping the clutch pedal until the pedal returns.

i cant get pressure to my clutch pedal in my 1995 saturn sc2. i changed out the slave cylinder and the clutch. I tried bleeding the slave cylinder, and still no pressure, why?


You cannot bleed these clutch hydraulics. They are meant to be a pre-bled sealed unit that you buy. You should never replace just the slave or the master. Buy them both and replace them as one unit which is already bled from the factory. Otherwise you will experience what you are describing.

Make sure you install the slave cylinder (into the transmission hole) first and then the master cylinder (pedal side) next and do not hook up the pedal until everything is installed.

If you take the slave out with the pedal attached it will extend the rod and ruin the hydraulics rendering them useless.
