G.box Coming Out - Which Jack To Use

[aircobra]

as per the "chuggin" thread, it sounds like some the main bearing is gone.

so the tranny its coming out

i never removed a box by itself before, but i do know from bolting it up to the block that its a pretty heavy piece of machinery

this guy has a good write up

http://www.biopatent.com/tranny.html

 

now, all have a is a cheapo supercheap trolley jack

http://www.supercheapauto.com.au/Product/SCA-Hydraulic-Trolley-Jack-1400kg/215072

 

and the last tranny i did was off a Fiat 126. Balancing a tranny on a jack is not my idea of fun at all

 

so i figure the choice are

1. get this http://www.ebay.com.au/itm/112496337234and spend the $200. will probably never ever use it again

2. get this http://www.ebay.com.au/itm/Transmission-Jack-Adapter-Trolley-Jack-Gearbox-Adaptor-suits-most-garage-jacks-/232158346013?hash=item360db73b1d:g:ax0AAOSwxk9ZlnWY

but even though the write up says "suit any jack", not sure it would fit

Question ONE is: has anyone tried the adapter

Question TWO is: does anyone have a loaner on Melb metro?

the gearbox has got some weight to it, sure, but can still be manhandled fairly easily. (depends on your strenght and fitness of course, dont bust yourself over it)
Its not too bad in the zed, down and backwards and it'll slip right off.
You could do it with a trolley jack pretty easy, just get a helper to stabilise the box while you lower and pull backwards, have the trolley jack running down the lenght of the chassis so it'll roll nicely.
I dont think the adaptor will fit your jack, its designed for the bigger style 3 tonne jack.

don;t have any helpers. more worried about getting it back on

[aircobra]

so my rebuild choices so far are Lurch  or Lou Mondello?

This /\....they aint that heavy. Drain the oil and pull the tail shaft to make it easier and to avoid having your balls doused in gear oil. Its much easier to manhandle than frig around with jacks etc. especially if the clutch isn't coming off as it should just fall back in.....

yep, got all that planned, last time a stuck a rubber glove over the opening and that worked

ended up ordering this - i like how its nice and low

I've taken out a few manual gearboxes including the one out of my 260z, what I do is get it all unbolted then lie on my back and use my hands and knees to lower it onto my chest then roll it onto the ground. Probably only weighs around 20-30kg

Auto gearboxes are a different story though! they would be closer to 50-70kg

jeezzus, i don't mind spending the $200. bigger hassle is getting the suspension bolts torqued. see the suspension forum

I use those small jacks all the time to remove and install gearbox. Just use a block of wood for more support or throw a rachet strap over the box. Or do it like how Andrew does it. L series box isnt that heavy

.. so far

1. lurch has come up with a great offer

2. stewart wilkins can get me a full rebuilt kit for $140 ( bearings + seals)

3. bloke in north melbourne can do a fixed price re-race for $800 + sychros, if required

.. just waiting for the jack to arrive

i have cranked up the car stands to the top notch, apparently you need 45 cm to clear the box

[aircobra]

got it out last nite after the jack arrived. wasnt that hard, the biggest issue was jacking up the car high enough, you need 50 cm clearance

just had a horrible thought -maybe its not the gearbox at all, could it be that i mismatched the clutch and the release bearing and that's where the noise is coming from?

If it goes away when the clutch is depressed then it will not be the release bearing, if it starts when you push your foot on the clutch then it is the release bearing

mystery solved

the bloke too apart the box , replaced all bearings and when i got it back the reason for the noise was obvious.

two of the large old bearings which he gave me in a plastic bag were rattling like crazy when spun. everything else was gold - synch
