Series 2a tailshaft lengthen

[normbourne]

Hey guys,

I've replaced my chassis with a military unit, one of the advantages is that it has raise the vehicle by approx. 2inches.

I'm now wondering if I have Compromised the length of the tailshaft..?

Can I compensate by installing a spacer between the drive face of diff @ and the flange face of the universal.

Thanks

Norm.

I'd check the part numbers for the shaft first, if thats possible. Military shaft may be the same.

With a 109 tail shaft being reasonably long to start with I wouldn't think it an issue. It might be with the front shaft as its quite short to start with.

One option would be to calc the length increase with the 2" lift
(a2=b2+c2, where a is the tailshaft length, b is the horizontal distance between the output flange and the pinion flange, c is the vertical distance between the centre of the output flange and the centre of the pinion flange, and 2=squared not times 2 )
and then see what spline length is still within the tail shaft when you extend it amount a (calculated above).

Does that make sense?

try gibbs truck parts, they do drive shafts , big place where you are, they may have a store there.

The 4 cylinder model only lists 1 rear tail shaft 553002 this was also used on the Aust Military series 2a's which had the raised chassis,(later this became the Land Rover 1ton model) and the front is 553000 with only 1 listed, I have a 68 military 2a with raised chassis and have had no trouble 20+ years use,you will probably notice a small recess in the forward X-member to allow for the steep angle of that front shaft, which has the sliding joint towards the front diff,while the rear slider is towards the transmission.

Hope that is of help.

cheers

Hi guys,

Many thanks for your advice and interest, it looks as though I'm try to make a mountain out ofa mole hill...!

Obviously there isn't going to be a problem.
