1951 M38 with Engine BLOCK ASSY LV7/AWO A6793

[syncros007]

I acquired a 1951 M38 with an Engine BLOCK ASSY LV7/AWO A6793. From my research this LV7/AWO engine was made by Willys for the British Military. My setup in the M38 is wired and plumbed as a 6V system. Does anyone know what the LV7/AWO engines were setup to run as, 6V or 24V, when sold to the British Military?

I am trying to decide on leaving the 6V system as is, convert back to the 24V as the M38 would have been, or convert to 12V.

Any thoughts or opinions would be greatly appreciated. I am assuming most would say to go back to the 24V, but that is pure speculation. I feel like if I could find solid information/documentation that the LV7/AWO engines were manufactured/sold/anticipated for 6V, sounds crazy, but I might just leave it 6V then.

Thank you.

It comes down to personal preference as you deduced. The M38 as a Jeep was a 24V vehicle so putting it back that way makes it more like it was originally.

6V systems can have their own short coming, but lots give fine service. You say yours is already 6V? If operating and reliable no real hurry to change it right?

For one f my M38s I settled on a hybrid 24/12V system and so far Im getting great service out of it. It uses a 12V starter, coil, alternator and light bulbs. It also has a 12V to 24V convertor that operates the original gauges and horn. It can be put back to original by changing the bulbs, starter, alternator and coil to 24V and moving one wire from the convertor. With the hood closed there is nothing to give away what I have done to anyone looking the Jeep over, even with a fine tooth comb. But I have the reliability of modern easy to source parts (cheap) and I can get them at the corner car parts store.

Just one opinion.

If you want to make it 12 volt, I have a 12 volt starter and generator that I took off mine. I am converting back to 24 volt. I can not vouch for function on parts as I just took them off and never ran them. The starter fits the early bellhousing.

I am not very familiar with the Background on the LV7 series L134's other than they are contract or license built for the British Commonwealth of Nations during or slightly after WWII. They may have been license built in Canada or England. They were never installed in an M38 by Willys. The casting design is mid 40's Willys IE casting 638632 which was WWII chain drive cam casting. They are almost identical. I would guess the engine is as mentioned above licensed built somewhere in the Commonwealth 40's or early 50's.



The M38 would hold significantly more resale value with a proper 641087 or 804380 Gear cam drive casting in it and of course equipped with 24 volt waterproof electrics.

I did a wee bit more research and found another suspect source for this LVC engine. Seems India had many reproduced in India after WWII for the many WWII left over British jeeps they inherited.
