Thread: JB's 1963 2A Build

Just a general question...

We obviously benefit, for the time being at least, on not paying VAT or GST under $1000 imports by post.

If you buy there you are obviously going to pay VAT at 20% which very quickly ads up and then you've got the added issue of Customs this side.

Am I chasing shadows here? Can you order and pay from here thus not paying VAT and instruct the merchant that you will collect without issues with British and Australia Customs?

Its a lot harder claiming VAT back once you've paid it than it looks on paper...

Cheers,

Lou

Hi guys, i would greatly appreciate any help or advice on the gearbox.

I have started cleaning out and draining the oil, have checked a couple of the inspection plates and inside looks like new, The top little plate that has a chamber like area inside is pretty dirty but besides that the gears look fresh.

a couple of questions:

1. How much movement/play should be in the main shaft that comes out of the bell housing?
2. oil looks pretty good, with a bit of water in it, no metal elements or debris from my limited experience seems ok. Pics attached.
3. the rubber grommet that houses the output shaft looks like it has had silicone applied both internal then around the grommet on the casting external. was this normal?

Gearbox - 251552244 B

any help, advice etc greatly appreciated. I am based in ashburton Vic.
cheers

Not very much, but there will be some - it is held by only one bearing without the front end in the spigot bush. In view of the lack of issues coming out with the oil I would be inclined to leave it, but you may consider it worth replacing all the bearings and seals in the box since you have it out. Be aware that this may uncover other things that you "might as well do while it is apart", and could end up costing quite a bit. But you will know it is all good!

Bit hard to tell from the pics, but no bits or filings is a good sign!

By "output shaft" you appear to be referring to the clutch release shaft. The use of silicone is not standard here - silicone was not a normal automotive product (in fact did not exist) when this gearbox was designed in 1932, but has obviously been used to keep serviceable the rubbers that had hardened. Since you have the box out, I would be inclined to replace these rubbers with new, although since they are only dust/mud excluders, it is not a major issue unless you plan deep wading.

Problem is that the modern replacement rubbers will decompose within a couple of years.

I purchased one a few months back and installed it about two months ago.
As the vehicle is being rebuilt, it hasn't even been subjected to heat other than atmospheric temperature and it's already perished and split.
Besides this they (current aftermarket ones) are not identical in design to the originals and do not fit correctly.
Basically just rubbish that will cause you the inconvenience of having to pull the clutch mechanism apart to replace them!!!


Cheers, Mick.

Much appreciated guys.

yes the rubbers are cracked but still serviceable. The movement in the shaft is only minor, but it's out, however looking at all the charts and instructions on working on the gearbox it frightens the hell out of me.

was thinking to send it out to be looked over, but like you say the old "might as well" then becomes a expensive exercise, one which i am trying to avoid.

I want to do as much on the car as possible myself however certain things i want to ensure are done properly, in this instance i feel out of my depth.

The Clutch actuating lever rubber shrinks with age,and will let road water in (rain) so the silastic was used,not much you can do about it,just keep an eye on the oil colour,the throwout face is nice and clean with no blueing,the actual throwout bearing is behind that casing,and runs constantly in G/box oil,unlike the Series 3 which had an exposed throwout bearing (Leyland cheapness)




cheers

any tips on getting the gearbox mount bolts off? They have a lip or cover over a section of the bolt hence the socket will not fit.

do i just bend these back?
