Isuzu clutch.

[Graham]

Wondered if anyone may clues regarding a clutch issue.  Isuzu pickup 09 2.5.

 

The other day the clutch pedal had a 'different' feel to it.  Sometimes it behaves normally; sometimes won't disengage fully at standstill and becomes difficult to engage first or reverse and if you depress it again it goes into gear.  As soon as your moving it seems ok.

 

There are no leaks from either cylinders and fluid level is good.  No noise from the clutch to indicate anything amiss.  Anything else I could check apart from getting someone to drop clutch out?

Possibly worn master cylinder seals. This won't show a leak as the fluid returns to the reservoir. Symptoms include the clutch gradually engaging when in gear and the pedal down. Also a vigorous stamp  operates the clutch but a gentle push doesn't

Similar issue on my old Isuzu truck which I lived with for a while until a non related gearbox problem had me have the gearbox out and noticed the thrust bearing fork was worn causing it to stick intermittently. 

Fitted another box from a breakers with a non worn fork and bobs your uncle no more sticking

So please correct me if im wrong...which I am on a regular basis .

You swapped over gearboxes  ...  when you could of just replaced the worn  clutch fork  ?

Glad you got it sorted though .

No the gearbox was knackered with a bust bearing and removed, that’s when I noticed how badly worn the fork was which explained the clutch not working intermittently

Think you might have the answer there.  It works a lot better with a quick push on the pedal.  I'll see if I can get hold of seals.  Thanks.

It may be easier to replace the lot

Yes at that price it saves a lot of fiddling.  Thanks for the link.
