2007 Defender 90 Puma 2.4 HT Stornoway Grey

Gearbox Bell Housing Bolts

In the process of removing the gearbox to inspect the clutch. Puma 90 H/T.

I've got the transfer box off, gear selector housing off, transmission cover off.

I believe there are 10 bolts, I can see seven of them.

Any tips or advice on removing the remaining three bolts from the top of the bell housing would be welcome.

Thanks, Keith

A helper is good.

Lots of socket extension bars.

One of you underneath guiding the socket extensions to the bolt, one of you in the cab to undo the socket.

All done by feel.

At least thats the way i do it but im lucky enough to have someone to help.

There's probably a better way if youve got more experience than me.

Thanks for that.

I'm on my own, that's why it's taken me several days to get to this point.

The vehicle is up on 12in blocks so I can get underneath or into the cab with relative ease. I do have a few extension bars so will give it a try.

I wrote a reply to this yesterday but it didn't post for some reason!

The ideas of doing this from the top with a helper are really good if you have that resource available to you. I'm obviously lacking in friends because I ended up doing this on my own.

Those bolts at the top of the bellhousing were the most difficult part of the intermediate shaft/clutch change job, I found.
Best method I would suggest if you're on your own, is with your feet pointing towards the front of the truck get a position where you're able to literally hug the bellhousing and get your hands to meet at the top. From there you have a hand for the wrench and a hand to guide it onto the bolt head. Be prepared to use a combination of extensions and UJs if you find you don't have the clearance to actually turn the bolt though!

Let us know how you got on!

Used a similar method. Boy were those top bolts tight. I think the box has been off before and must have been put back with a rattle gun. In fact I know it's been off because one of the top bolts was missing. Struggling with a rounded off head in an awkward place at the moment but I won't be beaten.
I found out too late that an AF socket is a better fit on the 13mm bell housing bolts.

A visit to "Toolstation" this morning. £25 lighter and I'm in possession of an Irwin Nut/Bolt removal set. Back home and the rounded bolt is off in a minute. All the rest of the bolts are out and the gearbox is supported ready to be removed tomorrow.

Thanks for the advice
