Clutch failure

**rocket scientist** · 18th July 2016, 09:52 PM

With my son proceeding to drive the Landy down the road on his L plates the other day, he was alarmed to suddenly have no clutch.

Lucky we were only 200 mtrs out the gate, so limp home and inspect the damage.
First thought was slave cylinder and sure enough, fluid every where.
Out with the slave cylinder, and as I pulled it out, the push rod dropped into the bell housing. Ouch!

So my Saturday was spent pulling the Isuzu out to inspect the damage.
After some analyzing the problem it was apparent the bush in the end of the clutch fork has worn and the pushrod has gone through the hole.
As shown in the photos the bush is well worn ( it was not broken until I pushed it out.)
I am assuming the bush is bronze or similar?? Any experience on this piece ?

I am also concerned about the wear on the end of the clutch fork, and uneven wear on the pressure plate fingers.

Slave cylinder seems OK,
I will of course be fitting a new pressure plate and clutch plate which are 9 years and 250k old, not bad I think.

I assumed the pushrod couldn't actually go through the fork hole if the bush wore out, but looks like that's not the case. Is the pivot rod a good fit in the bellhousing? It's common for them to get loose and I've heard they will eventually wear the hole out, move sideways and break the hole out with the same effect as you have had.

The pushrod does fit through the hole because of the worn bush which is why it dislodged completely and the slave cylinder piston came out as well.
Once I have cleaned up the bell housing I will assess the fork pivot.
Thanks Steve.

The fork has a hardened insert and is not common to get that bad unless all lube has been miss8ng for a looong time.

New fork and pushrod and lots of grease on pivot points..

The hole for the pivot rod is worn.
I hope that is a bush that can be replaced

There isn't a bush on there. Weld the shank of a bolt into the pivot and drill the existing hole right through and put a nut on the end.
