Hi all

 

Popped off my gearbox in prep for a AHU engine swap, I didn't use a 26mm bar to prevent the crown gears from falling into the gearbox - what are the implications of this?

 

According to Haynes it'll need a rebuild, is that the case?

So just had a fiddle with the gearbox, popped one of the driveshafts in and the input spun so maybe this specific issue either didn't occur on removal or its not an issue with the 1997+ 1.9 boxes. Regardless proof will be in the pudding when it's mated to the new engine.

So long as the input shaft isn't spun whilst the inner cv's are removed you'll probably be ok.

I've just bought a 2nd hand gearbox and forgot to check this exact issue, anyway when collecting it i looked in through the driveshaft apatures and the gears were still in place, and lord knows how long this gearbox has been sat around for, and getting knocked about.

You will not be able to put the gears back without opening the gearbox housing.

According to Haynes, opening the housing = rebuild. Find the nearest garbage bin and toss that book in.

But I was able to spin the input and both outputs spun? Unless I'm misunderstanding something.

The differential is different than the input or output shafts.

I know it's kinda your thing to post semi useless 1 liners everywhere, but it's not really useful or answering the question.

It depends on position of the differential cage when the driveshafts are removed. If you're not lucky, the gear might fall out through the hole into the gearbox. If you were able to put driveshafts back and they engage with the gears, it should be OK.

You don't know anything about my > 4300 replies in this section, otherwise you would have known that being a jerk doesn't make you smarter.

Hey Papez, thanks for pope-ing and answering my question. 😅

 

Hopefully now people searching the forum will be able to find a thread clearly explaining what the issue is as I struggled to find something hence making the post in the first place.
