Grate job I enjoyed following along. Now get out there and drive and don't forget the cold one when you get home.

I am in Shock!

That Gearbox re-build of yours is just Amazing!

How long did it take?

Getting that done by an outside firm would have cost a Fortune!

 

and you were wondering about my advice on an aerial seal.......lol

thanks for the comments

it took a few weeks over Easter last year, and the removal replacement has taken me ten weeks of a few hours on an evening and weekend when life isn't in the way

a quick update to finish off this thread

the car went and got a successful MOT ( ministry of transport ) test in the UK today , passed with no advisories

but more important, the gearbox performed faultlessly , in fact i couldn't detect the gear changes until i looked at the rev counter and saw it changing gear that way

its smooth and silent

just what i wanted

now i can rebuild the faulty box i took out all those months ago


BB ( happy BB )

 

Fanatstic result BB. I am really delighted that your work has produced such a brilliant result. Bravery is it's own reward, Fortune Favours the Brave! Any chance of a detailed step by step guide that can go up as a sticky, when you do the spare?

Congrats again
Greg

 

well,

i got to that bored stage again , so i thought i would perform an autopsy on my failed GM400 gearbox

after nearly giving myself another hernia, i lifted the box onto the metal bench , and the mop up began , no matter how much you drain these things they insist on arterial bleeding when you take them apart !!

so , i know the box was in its last throws of being almost reliable, but to what condition had to be investigated , when i removed the sump pan i was faced with THIS :shock:

TERMINAL CONDITION :shock: :shock: :shock: :shock: :shock: :shock: :shock:

there was a round magnet in the bottom , which i removed and found lots of metal filings on , this was before the picture was taken , ( it actually prompted the picture diary of the strip down )

the fluid was deceiving, as i did a partial flush a few years ago , but this was still a very dark colour and very viscous , the sump gasket came off in a thousand parts and was completely deteriorated , and the filter could be seen to be dirty

the main body of the box isn't any cleaner , and there is a black slime deposit covering everything

on taking the valve body apart all the metal parts are fine, but the separator plate gaskets just fell apart when touched , gain , terminal

on the good side............ :roll:

i think a good clean and rebuild with new service parts from a £150 kit will make it good again

now, don't get nightmares as crime like this is rare , oh , wrong programme,,,,,,,,,,,,,,

BB :wink:

 

for those that might be interested, and not bored of my exploits, lol

i have now completed over 400 miles with the rebuilt gearbox, and can report all is fine , and i am gaining in confidence and pushing the car a little more each time i take her out

so

if yours is going bad, have a go , whats the worst that can happen??
