Hey, i have a 72' 120Y Coupe and im in need of some advice, firstly i popped the driveshaft out a few weeks ago and need to refill the manual gearbox with oil but can only find a plastic nut right of the stick bout 2" infront but its not in the right place to fill up, do i need a syringe or something to fill it up from there???? , also i really want to replace the clutch plate but im not sure how to get it out, i have ramps, plenty of time and mates is it a simple enough procedure?, also any small cheap mods to improve horsepower to spin up the wheels for a bit of smoke and some fun? thanks if you can help me

Easiest way to fill up gearbox : 20litre drum with a drum pump and a small nozzle that will fit in the filler plug(looks like a little square shaped plug) - I think an open end 9'16 or 14mm ring spanner will undo it. This is also the level plug for your gearbox oil. I'm not sure what country you're in but I have used BP Energear easyshift oil for the gear box. Fill it up till it runs out the filler plug as this is also your level.
The drain plug is underneath (Obviously...)

As for the clutch an easy job.
Rip off the starter motor, gearbox etc.
When you are looking at the clutch undo the ring of bolts around the outside.
She'll all come apart nice.
If you have got an old input shaft use that to line up the new clutch assembly in the spigot.
Make sure you gease the spigot bearing.
Always clean the flywheel down very good with emery paper and make sure there is no oil or anything on it.
If in doubt and it looks like there are any hot spots on the flywheel - Get it machined.
If you wanna "spin up the wheels" u might as well get them to lighten and balance the flywheel while its out.........................................other than that spend some money on the donk........................

The best investment you can make is to buy one of those aftermarket service & repair manualsfor your model of car.
With the obvious serious mechanical limitations that many on this site seem to have, an inexpensive manual such as these will likely save it's purchase price on the first real job you use it on.
They seem to go for prices ranging from $5 to $15 on ebay & it's the best bargain you can buy.

Get the book
Read the book [twice if necessary]
Do the diagnosis & repair correctly, as per the book.
Relax with pleasant thoughts on money saved & a job properly done.

The best mechanics are the ones who can lay their hands on the information that they need to get the job done. These are the ones with the manuals for the vehicles they work on. Good library = good tradesman.

Yep. I'll second that Dodgeman.

Manuals can be picked up so cheap on Ebay nearly all the time - there is NO excuse for not owning one if you intend to have a go at some jobs yourself.

Just remember : some jobs will require a decent qualified tradesman to complete, if you want the job done properly.
And not after you have already botched up the job...............................................it will mean more $$$$$$$$$$

Thank you for your support.
You are right of course, some jobs are beyond the reach of many, but there are HEAPS of normal repairs & maintainance items that the average bloke can do with simple hand tools.
Even a starter repair can be made less painfull by taking it out, & refitting it yourself & saving the labour component which seems to run at $50 per hour or more these days.

The correct manual is the cheapest part of the job.
