Clutch issues HJ75

[Cmoney]

Got an issue with the clutch on my 1985 HJ75 truck. From a start position, unable to put into any gear with engine running. With clutch in all the way and try to force shifter into first, the truck wants to move forward although it is not fully engaged in first.
Since my mechanical ability is only behind the other 85 HJ75 owner on this site(no disrespect intended Charles) I would sure like some pointers.
Is this an adjustment issue or am I in deep do do with my "new to me" truck?
Thanks

1) Check fluid level
2) Crawl under truck and check to see if there is oil residue where linkage goes into slave cylinder. ( sign of leak )
3) Check master cylinder for for same symptoms.
4) If the truck has sat for a while the system may simply need bleeding to remove any trapped air.
You have now totally exhausted my mechanical knowledge.

Your the man!!! Hope you didn't take offense to my snide remark

Sounds very professional!
That's the way to check.

My advice is often described as "half *ss" but seldom as "very professional."

There is no mechanical adjustment on hydraulic clutches as the built in pressure in the system keeps the clutch "adjusted"

Sometimes you can get enough pressure to change gears by pumping the clutch 2-3 times before each shift

Another thing is the pedel box. I have had a few rippimg the bolt that holdes the peddle to the dash and that gives the same problems. Stick your head under the dash and push the peddle with your hand an look at bracket. Easy fix ,take the peddle out and weld it up .

Everything looks tight under the dash but excellent point and will store in my short memory box.
After pumping several times the clutch works perfect!! I guessing the real fix is to properly bleed the system or will this be an ongoing thing??
You guys are priceless, thanks for the advice to a non-motorhead

Advice and the occasionally sarcastic remark are always free.

They only get air in them when the seals are leaking or from someone who didnt know how to bleed them properly when changing the fluid.
Prepare for a new master/slave cyl,what you have now may linger on for a few months but it wont last long when you start driving it daily.

I think the master cyl is interchangeble with an FJ60. From memory there is about 6 part numbers for 60 and 70 series master cyls of the same years,but they are all much the same.
Ive had good luck with aftermarket types.

If you have the power boosted clutch you will need the applicable part

Changing the master cylinder may be fairly straight forward however the slave cylinder can be more complicated. It appears that Toyota put a variety of slave cylinders on their Cruisers and the linkage is different between units therefore they are not interchangeable. ( I learned this the hard way.)

Yes,the slaves are usually unique to each engine and are on different sides. They are still easy to install and bleed though.

I just last night found my slave was begining to fail, very easy to replace, two bolts and the fluid line.

The issue I had was not the ease of changing the part as much as it was getting the correct part to change. The correct part according to Toyota for a 1985 HJ75/2H was not even close to the unit on my truck. The actual slave cyl. on my truck was considerably larger than the "correct" Toyota version and the bolt pattern was totally different.

I wonder if you have a 3F slave cyl? They are huge,probably twice the size of 1HZ slave.

All I can tell you is my current unit is longer and has a larger diameter and
works which beats the heck out of being towed back home.
