LT77 Gearbox
When the output shaft from the gearbox, and transfer box input gear finally give up, which part usually fails first the shaft or the gear?
Cheers
Rick
IME the shaft with the gear not far behind.

both.
or rather, don't bother replacing one and not the other. Equal wear on the one I took out of the disco I had then, which hadn't in fact failed, but was very worn.
I'm now looking for another g/box as the sycros are weak on second so it's not worth re building this box. I know it's a lubrication issue with the gear and shaft but I can't understand why these should wear so much when the splines on the clutch don't wear and they aren't lubricated apart from a touch of grease when fitted.

The clutch splines aren't driving the vehicle though so the load is completely different.
I got a recon box on the 110. Initially getting second was an art but it has slackened up nicely now. No doubt due to preloads on bearings.

Are they not? What is then?
Ignore me - I mis read that. I'm thinking clutch forks. Doh!

You been on the beer?
Feeling like s**te at the minute..... Ian_R has released an ancient rare Swiss Man-Flu in to the air and I think I'm it's first victim. It's real bad!
Took a sickie for the first time in 18 months last night :-(
But yes is the answer to the question! ;-) That said I've only just lined up my first can.

Definately a Wuzzz. The last time I took a sickie was about 3 years ago but I was in hospital for 3 days being given 1 gram (yes 1 gram) intravenous injections of penicillin every 4 hours.
Be aware of the early symptoms (mildly inflamed red tracks under skin that are tender) of cellulitis and *do not ignore* them! Took Incapacity Benefit for 3 or 4 weeks and it was a good 6 months before the affected leg was more or less back to normal.
Kin'el!
Mine I think is the first of many from our latest Diddy_D. Always seems that they get a sniffle and I get totally grounded by what ever they pass on to me, oh the joy of parenthood! :-)

Rick Hi,
what we usually see here in Greece is the shaft going first. But when the symptoms are apparent it is a good measure to also change the gear since by then it also blunts the sharp edges of the splines. Blunt splines on the gear can easily damage the new shaft.
What we recommend over here is to change the shaft and gear on the same time. After all prices for the gear have dropped significantly and it is false economy not to change it. Especially if the existing gear on your car is not the drilled type. I would also suggest you fit the Steve Parker oil feeder plate.
Take care Pantelis
Quite...
Are either at school yet? They'll bring all manner of things home to pass on from the simple common cold and head lice to chicken pox. Have you had that? I don't recomend having it at 42... It's very mild as far as feeling "ugh" is concerned but the spots are something else.
