Outer Limits 4x4 Board

G'day all i've done a search and could really find what i wanted to know.

The gearbox in my middy is a bit stiff swapping cogs and the clutch is bloody heavy! I'm not sure if thats just how they are or what. My other car, a nissan pulsar had a heavy duty clutch in it that snapped a clutch cable every year, but this is heavier and i think it may give my knee some trouble! Is there much i can do to lighten it up abit?

Currently the friction point is fairly close to the floor and when the pedal is fully depressed i can hear a constant nose from the hydraulics or something? Also the gears dont really crunch, 3rd sometimes feels a little toothy if you knwo what i mean but if i stop at neutral and blip the throttle the gears go in better, so i was thinking of putting in some redline shockproof light weight or super light weight gear oil, anyone done this before with good results?

cheers

If you have the H55F box it is basically a slow changing box, you wont be able to shift it like a passenger car.

Drop a bit of oil out of the gearbox and check how thick it is, someone may have put lsd type diff oil in there which will make shifting gears harder.

I would suggest doing an oil change on the 'box and transfer, wont hurt. check the oil levels first to see if either is low, which may indicate that the seal between them is stuffed which is pretty common. (if the seal is stuff you will find the transfer case is overful with oil) When replacing the oil just refill with a quality gear oil, dont put grease, or loads of super thick addatives in there.

I would suggest checking all your clutch operating mechanics/hydraulics, spray the pivot points with some CRC/WD40 and see if it is easier to operate the pedal.

Also check how the adjustment is set up on the mastercylinder, it may be screwed in too far that could be giving you grief.

If you have a vaccum assisted clutch booster on your cruiser, check that the diaphram is not stuffed, pull the vaccum hose off, (leaving it attached to the booster) suck on the end of it and you should be able to stick your tongue on the end of the pipe and it should stay there with vaccum, if not you have problems


Years ago when I was young and dumb I had a CJ6 jeep. I went through 3 clutch cables in around 3 months and ended up with a left leg like arnie schwartzathingy before I pulled the gearbox out. I found that the clutch fork pivot point had a cup and ball arrangement on it, and the ball had fallen out somehow. So instead of a nice round pivot point it had a jagged area to work on. I put the ball back in and nearly pushed the clutch pedal through the firewall when i used it first time......

Check all the minor basic and CHEAP things first.......

If you dont have a vacuum assisted clutch this may help:
