Morning all
My 3/89 HJ61 Sahara 12HT 5 speed manual gearbox has a slight whine in 5th gear and throw out bearing small noise at idle. Car has 190000km, gearbox was replaced by toyota 70000km ago so gearbox is only 70000km old. Has anyone heard of gearbox problems with this model? This vehicle was a torack tractor from
Melbourne with a woman driver from new so I'm guessing its been laboured around in fifth gear?
Thanks
Steve
PS Love the Sahara and HJ47's, always good for a yarn.

The gearbox noise will gradually get a bit worse. You'll probably find the same noise in all gears except 4th. Common in Toyota 4 and 5 speed boxes of the time.
Mine did it for about 80,000k before I sold it to a friend who had the box reconditioned.
The throwout bearing noise at idle is different. I'll assume its present when the clutch is not depressed. Its just a nuisance, and caused by the bearing just lightly touching the diaphragm spring. Only way to get rid of it properly is to replace the clutch - the diaphragm spring usually has a small groove worn in it - the bearing is usually OK. If the noise is present with the clutch pressed, then it is the throwout bearing or spigot.

Good morning SteveD.
I have a Toyota 84HJ/47, with a 12ht motor in it with a 5 speed gear box, and have just been through this with
mine,and the problem i had was that the clutch plate had started to give up,and the 5th gear was starting to get tight to put in to 5th gear, and was also starting to get noise at 1500 revs, so i changed the clutch and preasure plate,also had the fly wheal skimmed, to clean it up, and new bolts for the clutch and fly wheal, and a new spigott bearing, thrust bearing, while i was doing this, i also did the rear oil seal on the motor,If you do change the clutch make sure "they" dont use after market parts,as the 12ht motor is different to the 2h, as the motors have a different clutch plate,and preasure plate, make sure you go to toyota and
check it out for part numbers and you will see what they say, as the place where i have had the motor put in said the 2h clutch plate was ok, but the 12ht motor is different, and when it all fell appart they had to do it again at their cost,and i paid the difference for the new 12ht clutch plate kit from Toyota, also you get the thrust bearing in the kit so dont let them charge you for it, as a seperat item, and what i found with the old 2h clutch plate was
the springs were different on it to the 12ht plate, and were stronger, When your gear box was replaced by Toyota did they change the Clutch plate and preasure plate ?????, since i have done all this to the tojo, it is like a new toyota to drive. Hope this helps with what problems you have.
Cheers for now....William H...Bunbury...WA.

Maaaattte, I have a 8/84 HJ47 which is in as mint condition as u could get for a 24yr old toyota, not a mark on almost anything, my 47 is my toy but gets used. The reason I bought the HJ61 was for the engine and gearbox for the 47. When I got the 61 from
melbourne it was in such good condition I've decided to keep it for a few years before it gets gutted for the 47. I'm a diesel mechanic and have fitted power steering to the 47, it made it a heaps better vehiclle, lock to lock in a car park with one finger. Pity the old 2H is such a boat anchor. If I can help with any info on your 47 I would like to help if needed, I would love to hear more about your 47, If you had a photo of in the engine bay that would be great.
Cheers Steve
