[Healeys] Gearbox oil volume

That’s very interesting. Seems like they got the whole thing into a muddle on Day One and never really recovered.

Makes trial and error, one of my usual fallbacks, seem quite sensible in the circs.

My original BN1 1954 Service Manual has an  "ERRATUM '  sticker on the inside cover stating :-


                                       Gearbox/overdrive Oil Capacity 


                            The combined capacity of the Gearbox and overdrive is

                             5 1/2 Imp. pints (dry) and not 4 1/2 Imp pints as stated  

                            After draining,  1/4 pint of oil will remain in the overdrive

                            hydraulic system, therefore ,only 5 1/2 pints will be required

                             for refilling.  


                                      Pubs. 996B and 997A December 1954


So when filling from rebuild add the extra 1/4 pint  ....   5 3/4 pints


Later editions may have carried the correction  and side and top shift gearboxes may vary

Well that’s interesting as I will be buying the oil for the BN3’s gearbox this week. It is a 100S gearbox with a 22% OD that has been completely rebuilt and apart from the oil used in the assembly it’s completely empty.


My 1968 BMC Workshop Manual (AKD 1179H) that I bought new in September 1974 for $7.00 states that the oil capacity for a side-shift gearbox fitted with an OD is 6 ¼ imp pints, 7.5 US pints and 3.55 litres. I states the same for a centre-shift box as well. So I will be buying a 4 litre container and store what’s left over for the inevitable leaks.


Talking about leaks I was watching a Jay Leno video of his Daimler SP250 over the weekend and he made mention that all things over 50 or 60 years of age are bound to leak.

Offhand, I'd believe the workshop manual first.  If you're doing a drain-and-fill, you don't know for sure how much residual oil is left so you have to go by the dipstick anyway.

1)      My car’s Driver’s Handbook page 7, (AKD 3915A) tells me that:

my MkII BT7’s gearbox takes 5.75 imp pts (6.90 US pts) 

its overdrive takes 1.33 imp pts (1.75 US pts)


2)      My BMC Workshop Manual (AKD 1179D) tells me that:

gearbox               4.0 imp pts (4.80 US pts)

Total gearbox, overdrive fitted, 5.25 imp pts (6.30 US pts)


3)      My Haynes manual goes for:

Standard box:- 5 imp pts

With overdrive:- 6.25 pts              


4)      My Autopress manual (Kenneth Ball) goes for:

Standard box:- 5 imp pts

With overdrive:- 6.25 pts


ie only Haynes and Autopress agree.

I’ve had this Healey for +/- 20 years and I’ve never noticed these discrepancies! I seem to have survived by using the dip stick, but I’d bet that I’ve overfilled more than once.


Any ideas? I don’t recall this coming up before.....
