installing new gearbox. tips please.....

[Guest]

ok so i have got another gearbox to stick into my BG5. Any tips when putting it back in?

i haven't touched the clutch or anything, is they anything i have to line up properly etc?

Also i will be replacing the oil in the gearbox. What brand should i use?

Thanks in advance

Jack the front of the engine a wee bit, I find this makes it easier to line up.

[Guest]

ok will do! thanks

Dont use the bell housing bolts to pull the gearbox onto the engine, make sure you have it so it pushes up relatively freely without any tension on the bolts. Seen damage caused this way from people who should be working on massey fergusons instead of subarus.

[Guest]

yeah i have heard about, just keep wriggling and pushing it till it meets up. cheers

What these guys have said, Take your time and make sure everything fits nicely first

If its a man box - put it in neutral, makes installing them a hell of a lot easier (not sure about auto's, i refused to put an auto box on a subaru engine)

I use a rope around the bottom of the gearbox with sometime standing on the strut towers to lift the box up and guide it on, jack underneath the gearbox to keep it level and it usually just slides right on in

Recently we just removed the whole engine for shits and giggles but that was for a auto to man conversion

I wedge a mallet between the alternator pulley and the radiator support, seems to be just the right size. Then get a helper to lift the bellhousing by standing on the strut tops while i lie under the car with the tail shaft on my chest. Then its an easy matter of lifting and wiggling the back end around untill it slides on.

Also if you dont have a clutch alignment tool - just leave all the pressure plate bolts finger tight and do them up once the gearbox is on through the clutch fork hole.

(Next time i do it - will take lots of photos and do an idiots guide write up)

You may be the pioneer sir, but i am taking the credit!

Used the same technique on Shauns car over christmas and it worked well

Same technique we used when we (* you coz i munched my thumb) in Nov when we did my Forester. Though we had the magic clutch alignment fairy help us out when we went looking for a clutch alignment tool and found it all sorted when we got back 8)

I lifted one up by myself. I lay under the car and pulled the gearbox up onto my chest, then pushed the bell housing up on my knees and lifted the tail shaft with my hands. It was really painful, but worked.

heres a tip. dont force it or hang the input shaft from the clutch plate without having the box on the dowels in the block..., also have the box in a gear and have the driveshaft in the rear of it so you can turn the input shaft to line up the splines .

good luck.

[Guest]

wow thanks for all you nice tips, ill be giving it a crack tomorrow.

cheers

Or you could use a hoist and a gearbox lifter and a clutch alignment tool

I can only wish that one day I will have my very own hoist in my garage.

[Guest keltik]

On a side note - if anyone DOES have a hoist in their garage, id love to use it for a few hours to rip my gas tank out

Thats how we do it when you need to have it changed in less than 30 mins. Much faster and if you have the right technique it doesn't hurt at all. Just takes a bit of benchpressing strength so I usually opt to be the one to help align it and wiggle the driveshaft
