Transmission service?

Hi everyone!

Im currently about 2 months into my landrover ownership, its been a ropey affair already, but i love my 90!


So the transmission on my 90 is 'ropey'
To say the least!

So im wanting to give my transmission a service. Is there service i can do?
Diff oils, grease etc?

I tried to grease all the grease nipples on the vehicle, i did 1 on each bar thing, i think there a prop shaft??

I did 2 U'Js which were engine side,...however my grease gun fitting wouldnt fit between the knuckles on the tail end ? Like i needed a smaller fitting to get in there, is this common?
How many grease nipples are ther in total, 6 ?

When i change gear it clonks pretty badly as i apply throttle..

And lastly when putting the little gearstick into the high range(normal driving) it wont go, i have to put the vehicles in 1st and gentally apply backwards pressure whilst releasing clutch until it drops inn, is that diff on its way out? Or transfer box?

And i think my UJ's are nackered.


Sorry if none of this makes sense, 1st defender!

I learn quick !

And thanks for the help in advance, ive noticed a wealth of knowledge on the forum!
Thanks graham

Diffs EP90 or I'm using 80-120 in mine, gearbox oil varies I'm again using 80-120 but I'm running an ancient cast iron box, you can put new grease in the hubs and again oil in the transfer which is EP80-90 IIRC


As to high range, why you're starting in low in the first place is a little odd as you shouldn't need to unless towing really heavy. Rocking the car forward a little is standard practice anyway, mine prefers to go in when its barely rolling forward instead of standing still

I was driving up a very steep rutty muddy hill in low range in the rain that how i came To notice
My 90 is a 1989 and the gearbox is original i would imagine
And is close to being an antique lol

Thankyou for the oil advice, i have a pair of replacement door bottoms to fit this weekend, i will change oils at the same time

LT77 box in that case if its original, reverse up and right

The clunk under acceleration could be caused by any number of these:

1. Worn CV joints
2. Worn halfshafts
3. Worn pinion in the diff
4. Propshaft Uj's
5. Wear between gearbox mainshaft and transfer box input gear (This was the case with mine. Needed a recon gearbox and as I was doing the input gear, rebuilt the transfer box myself.

Luckily i have access to a ramp, so i may
Get the old girl on the ramp this weekend and check, ive been in a few defenders, and the transmission in this one feels pretty slack, so everything may be abit worn!

Thanks for the above mate, thats exactly what i was looking for, the common reasons

Thanks

Oh ****, yeah up and left my bad

I'm getting my hands mixed up down and right is R380

Probably won't be causing the clunk but also check for wear in the drive flanges but you'll need a new gasket for when you put it back on

Treat me as a complete idiot, whats the drive flange? The pole that has the grease nipple? Or was that the prop? Maybe a need a diagram that i can revise!
Sorry that im stupid!

The propshaft is the pole that comes out of the transfer box to the axle. The drive flange is the thing in the centre of each wheel that the halfshaft goes into. Its got 5 bolts holding it on.

was the cause on mine, just one dodgy one.

The drive flanges are the bits in the middle of your wheels with 5 bolts holding them on and a rubber cap in the middle.

Buy a haynes manual and read it, will help

I didnt even consider a haynes manual, ok thankyou, understood... Drive flange is what i know on a fwd car as a driveshaft, well atleast situated in the same
Place!
I live opposite a halfrauds so i will pick a manual up tomorrow

Nah think of your driveshaft on a fwd car as the half shaft on a landrover. In a car the driveshaft goes into the hub which is what turns the wheel. On a landrover the half shaft goes through the hub (in effect) and then the wheel is turned by a splined plate fitted on the outside of the hub

I have just changed a drive flange have a look at this page in my project thread to see what I am going on about, photos down the bottom of the page

I'm surprised that this thread has got so far with no one suggesting that you do a search, there are loads of transmission topics on here. I would say you're first tasks are 1) learning what all the poles and boxes are and 2) changing all the fluids. And drivel, learn left from right!

I do need to learn what all the different components are, however there if you read correctly.. It wasnt me that got my right and left
Mixed up.


I have a trackcar/racecar that ive built myself, and know all components, wiring diagrams, compression ratios etc!
Ive never owned a 4x4, and it had lots of additional tranmission related parts, props, drive flanges, diffs, transfer boxes etc..


Im learning by getting involved, just reading doesnt always sink in.

Thanks for the reply, and as said, will check the fluid levels
And have a read through the blog above

Dude he wasn't saying you don't know your left and right he was saying doc evil doesn't lol, a lot of people refer to him as 'drivel' lol

No worries. Read some of his posts and you'll understand why.

I would reiterate though, don't just check the levels but change all the fluids. It makes loadsa difference - well it did to mine anyway.!

Have you checked the gearbox output shaft, mine was clonking badly and this was the cause:


It's currently in having a rebuilt gearbox and X Drilled transfer box bearing fitted.
