Be3 Differential Housing Torque Settings

[Henry Yorke 269 3 Cars]

Hi,

 

The Haynes manual doesn't clearly state what the torque settings are for the bolts to mount it to the main gearbox case

 

There are:

• 4 x 10mm on the top and bottom of the case
• 4 x 17mm holding the diff bearings
• 3 x 13mm holding the speedo drive onto the diff housing

 

Can someone enlighten me please on the torque settings for the above

 

I found the 17mm crownwheel bolt settings of 65nm and these are threadlocked

 

I assume these housing bolts are not threadlocked.

 

regards,

 

Henry

I seem to recall doing mine to 25Nm

They don't take any sort of load - and are really just to make a good seal on the diff housing. Used a smear of Wellseal and haven't had any issues.

Was that all of them or just the big ones? I did mine to 41nm as Haynes referred to 10mm bolts at that and 7mm at 12nm on a BE1/5. It seemed a lot of torque for 10mm bolts on a BE3 so I chickened out! I used a smear of RTV around the mating faces but have yet to fill it with oil

This is BE4 citroen specs, can't find BE3 listed anymore.

I asked the same question a while back as the haynes I was looking at didn't list a great deal either

 

Final drive half housing bolts, M10; 41Nm 30lbft
Final drive half housing bolts, M7; 12Nm 9lbft.
Speedometer pinion adaptor; 12Nm 9lbft
Final drive extention housing bolts ; 15nm 11lbft

 

There is an older version of the haynes manual that has a good 40 or so pages dedicated to gearboxes which is very descriptive.

Aha! I think I see my mistake! I have that old orange Haynes manual too. I was assuming it was a 10mm and 7mm bolt when actually an M10 is the 17mm and and M7 is the 10mm one. It was getting late! That is actually what I tightened them too anyway, but I thought they were on tighter than that originally.

 

Thanks Sam for the useful diagrams as it is bolts 3, 4, 6 and 19 which I was after. I have also learned that 1 daNm = 10 Nm (well I assume so anyway!!)

Yep, for some reason all the torques are in daNm on cit service. No probs on the diagrams.
