hzj75 Troopy in Mexico, having clutch issues

[TreadingLight]

I'm down in Baja with the Troopy. It's been rough and rocky travel but having a ton of fun.

Today though i noticed the clutch fading when maneuvering out of camp. It holds pressure long enough for quick shifts but seems to lose pressure when "feathering" the clutch pedal (ex: backing out of a parking spot).

No leaks anywhere but the fluid looks dirty.

I'm guessing either the master or slave cylinder seals are failing internally.

Questions:
* Suggestions on how to tell which it is?
* From looking at toyodiy.com it appears these parts are specific to 70 series cruisers. I fear these parts will be really hard to get in Mexico (never sold them here). Are you aware of any crossovers?
* Could they be rebuilt woth generic parts?
* How likely is it to fail completely? I'm wondering if i can limp home (hwy 1 doesnt require much shifting) or if I'll need to hole up here for a while. I'm about 100km from La Paz, where i can findechanics and such.

Many thanks for the advice.

From toyodiy.com site, for the master, it looks like either:

31410	CYLINDER ASSY, CLUTCH MASTER
31401-60060	W(*CLB(MOUNTED INside
31410-60430

For the slave, either:

31470	CYLINDER ASSY, CLUTCH RELEASE
31470-60160	(01/1990 - 03/1990)
31470-60161	(04/1990 - 04/1993)

Tips on figuring which i need?

Also if im reading the site correctly now, these may be the same hydraulics used in some 80 series? If so thst could make this much easier.

Well part numbers be damned, I am at a brake shop recommended by a Toyota mechanic recommended by another Baja traveller. They found a bad seal in the master cylinder and are "rebuilding" it now. I'm ordering new replacement master/slave cylinders to pick up in California on my way north for a better/lasting repair.

A 3/4" rubber grommet (same size as a Cherokee) is the fix for now.

So i guess my yota is now .5% mopar?

I thought the 60 series master cyl was the same but with a different part number. There is 6-7 part numbers for these, but they all look the same.

You probably could have limped it back over the boarder but it's better to be safe than be stranded on Interstate 3 somewhere.
Definitely swap out those Mopar parts for OEM Toyota though

Hello,

The rubber grommet/seal will last enough to get you home. 0.5% Mopar helps sometimes.

Both master and slave have not changed much over the years. You can still order them new.

You can also order a clutch repair kit as well.

Pick up some HEMI badges on the way back!

It was getting worse and worse. By the time i rolled into la paz i was rolling through stop signs, granny shifting, and sweating starts from a full stop. But in typical baja fashion, it's all good now. And even better, i can now hit some more of the trails I've got on my list as we go north.

When i get back I'll buy a new aisin master cylinder assembly and put that on. I'll probably buy a rebuild kit and turm my current ones into spares. Build up my spare parts supply.

Any suggestion on what part numbers I want to get the correct cylinder assemblies?

Any suggestion on what part numbers I want to get the correct cylinder assemblies?

Tracking down parts in North America for my 70 is a bit complicated. I think I'll be ordering the parts via www.partsouq.com out of the middle east.

Before I do, I just want to check on a couple of details. First up, even though every piece of paperwork I have on the vehicle says it was manufactured in 1990, the VIN decodes to a 05/1993 TOYOTA LAND CRUISER (HZJ75RV-MRQ). Weird.

When I look up my VIN on partsouq.com or on toyodiy.com, it gives me two options for the master cylinder assembly.

There are several options available for your car, pick the correct one.
3140160060	FZJ70,75,HZJ7#,PZJ7#..RHD..(ARL,GEN) W(*CLB(MOUNTED INSIDE))
3141060430	HZJ7#,PZJ7#..MTM

@JuanJ - the part # you gave me for the master cylinder, 31410-60400, cross-matches to a number of gasoline FJ70/73/75 cruisers from 1990-2006. Mine's a diesel. Not sure if that matters.

I'm inclined to go with either the 31410-600060 or 60430 since the database gives it a closer match. Are they really all the same? They have different prices.

And what the heck is a CLB?

 

[JuanJ]

Hello,

Yes, the part number I gave is for a gasoline/petrol model. My mistake.

CLB stands for Clutch Booster.

[TreadingLight]

No worries - thank you for your help. I'm trying to figure out which of the two cylinder assemblies I need. Can we tell by looking at it?

I don't see any evidence of a clutch booster on this rig. There's no vacuum line running anywhere and I don't see any booster mounted in the engine bay or on the firewall in the cab. Am I safe to order 31410-60430?

 

[TreadingLight]

Nuts. Something is wonky on partsouq.com - when I search for the master cylinder (31410-60430), I can find it in their diagrams and database but when I go to bring it up it substitutes the part for some timing kit for a completely different engine.

The closest match I can find seems to be 31410-60620 (3141060620 Toyota CYLINDER ASSY, CLUTCH MASTER - https://partsouq.com/en/search/all?q=3141060620) which matches to FJ7x gasoline model. Would it work? @orangefj45 - do you think an HJ/FJ master cylinder would be interchangeable?

It's starting to look like I'm going to have to put the temp mopar fix to the test as I'm trying to set off on a 5k mile drive starting next week.

 

[TreadingLight]

Well, I've emailed partsouq.com about what I assume to be a website / database error and rang up every diesel cruiser shop I've done business with up and down the coast but haven't gotten anything back yet.

@roscoFJ73, how confident are you an HJ6x part would fit?

@JuanJ, do you think the 31410-60400 for an FJ7x would be a good substitute for the 31410-60430 part specified for the HZJ7x?

 

[JuanJ]

Hello,

As far as I know, the slave cylinder is different between FJ7x and other models. The master cylinder is not.

I think 31410-60400 is a good substitute.





Juan

 

[TreadingLight]

Thanks Juan. It doesn't look like I'll need it though. Partsouq tech support got back to me (over the weekend even) and directed me to 31410-600432 for the HZJ75 clutch master cylinder.

The 31415-60020 master cylinder gasket is not available but I imagine I can reuse my old one or get creative making something.

Once I convince my credit card company this is a legitimate transaction I should have the order placed.

 

[JuanJ]

Hello,

I am glad you got the right part.

Make sure you get a master cylinder kit. Cheap insurance.





Juan

 

[roscoFJ73]

@roscoFJ73, how confident are you an HJ6x part would fit?

A HJ61 c/mcyl will fit on a 7* series of the same year, 84 -90. The HZJ75 c/cyl has an accumalator (I think its called that) on the c/mcyl. But looking at the pics, its possible the flange is angled different. Does yours have a booster on the clutch, because they are different again? So, not too sure.
