LT77 clutch job...difficulty

I imagine with 82k miles my 88 D90 probably has the original clutch...its starting to engage about 2 inches from the floor....it also is making a noise at idle unless I engage the clutch...i am thinking throw out bearing....unfortunately I can't get the truck into my garage where I have a lift...can most decent mechanics tackle this who has never worked on a Rover?

Sure. No different than any other rear drive vehicle.

You should plan, though to replace all of the throwout parts and slave cylinder and the rear main seal at the same time. There are options for HD throwout bearing housings.

You don't need a lift. An engine hoist or tranny jack on the side of the road will do.

Pedal is pretty close to the floor today...starting to question the clutch or could it be the slave from the pedal to the clutch itself?

Most likely hydraulics.

I had the same issue, the clutch MC was the culprit. It's a PITA to remove on a LHD truck so I went with a genuine part instead of an aftermarket unit.

You just have to know the secret trick to change the master. If changing do the slave and hose as well. Make sure they are OEM branded units. The Chinese one have a high failure rate.

The trick it to unbolt the brake MC as to avoid taking off the left wing. Yes but it still is a PITA requiring various mechanics yoga positions including mangled, twisted down dog.

This is a RHD unit so I hope a tad easier...will order one up before I start playing with the clutch itself...

RHD, piece of cake but wait till you have to change the accelerator MC. You will be lucky to even locate it let alone replace it.

I've read about people saying how much of a pain it is to replace the clutch mast cylinder, but I found it to be pretty easy. I just unbolted the brake pedal housing and booster IIRC.

Just checked and the reservoir is very low...at the bottom of the neck...going to try and refill and see if I can get some more pedal...all the piping looks but cant see completely underneath....however there is so much residual fluid drippings on the underside it's hard to tell what and where there are leaks...at least I stopped all of the leaks on the top side of the motor...

That is the exact symptom that my failing MC had. If you have fluid dripping from the bell housing it is the slave cylinder.

I assume that you have to separate the bell housing to get to the slave or is it an outside job? It sounds like the throw out bearing may be bad too so if it has to be opened up I guess I should replace the clutch, throw out and slave all in one shot...

To do the slave you can do it without opening things up. To do the throwout bearing, fork, clutch itself you need to separate the tranny from the motor.

Step by step slave replacement

Step by step clutch master replacement

Buster does good work and ah like his narrations.

I have seen a few where the slave cylinder leaked which I believe led to the failed throwout bearing. If the bearing is noisy it needs to be replaced.

This isn't something you want to do again any time soon. I would go with LR factory parts if it was me and not aftermarket.
