Be1 Pinion Into A Be3 Box? Will It Go?

[littlemike 0]

Hi. I've just bought two gearboxes to make up one.

 

The first box is a be1 1.9 box that's fitted with an mi16 final drive. It has 62/14 crownwheel + pinions. It also has a Quaife diff.

 

I need a be3 box for my 205 though so the second box I bought was an mi16 be3 box.

 

Having taken the standard diff out of the be3 mi16 box to fit the quaife I found out the crownwheel + pinions have 65/16 teeth! It's not an mi16 box then is it?!!

It has 405 linkages though so I'm assuming that it's a 405 sri box?

 

Now can I fit the be1 cw+pinion into the be3 box? I'm thinking not, but I don't know!

 

If not then neither box is any good to me + I'll have to fit the quaife into my existing box that I'm using + sell the 1.9 be1 box with the mi final drive still fitted, but with a standard diff. Arggggh

All BE1 and BE3 CWP's are the same, As said the 16x65 is the SRi box

Thanks Miles.

 

So I can swap the output shaft from the be1 box into the sri box, but keep the sri gears? Or does the pinion come off the end of the shaft?

Result.

 

Knowing that I could swap the cw+p betwwen the two boxes as Miles said I stripped the be3 box down tonight (I stripped the be1 box last night).

 

I pulled the two shafts out + thought while I was at it I'd count the number of teeth on each gear & compare it to the be1 box. To my surprise every gear had the same amount of teeth!

 

 

1st= 38/13

2nd= 37.20

3rd= 34/25

4th= 31/29

5th= 32/37

 

Which by my calculations means the ratios are:

 

1st= 2.923

2nd= 1.85

3rd= 1.36

4th= 1.0689

5th= 0.8648 (~0.865)

 

 

So the gearbox that I bought as an Mi16 box that has a 16/65 tooth cw+pinion is actually a 1.9gti box that's been fitted with a 1.6gti final drive!

 

 

The only trouble now is that I've got to put it all back together!

 

Don't the selectors take some getting back in correctly!? I think they're in right now although the 5th gear selector can fallover/out when you select certain gears (without the other half of the casing in place)!

 

I need some sealer now & I think I'm going to get a new oil seal that goes on the input shaft as due to the amount of times I had the shaft in & out whilst trying to get the selectors correct I've probably worn it out!

Don;t forget to make sure the input shaft is shimmed up correctly, got you on that one!!

I hadn't noticed any shims? I didn't actually take the input shaft apart all I did was remove it from the box and then put it back in place as all of the gears are what I need. Where abouts are the shims Miles and do I need to bother as I haven't actually changed anything?

 

Thanks.

I'm about to embark on swapping the 8v 1.9 gears onto the MI16 CWP - can you tell me Miles or anyone else how you shim up the input shaft? I take it there is an endfloat measurement to prevent backlash? Is there any other pointers I should watch out for? A mate of mine had his Golf box "rebuilt" for £600 and it sounds bloody awful - I wonder if this is a clearance issue.
