Off Color- Oliver

I was told that Oliver 70's used continental engines in them, is that right? I couldnt find information on them so thought I would ask you guys. If I remember the years of these tractors of mine they are a 1945,46,47. Thanks Anthony

Don't know, this says Waukesha.  Seems right.

http://www.smokstak.com/forum/showthread.php?t=36181 says they were a Continental made for Oliver and use some F600 parts. The post refer to an oliver collectors webpage but its closed to visitors without signing in. http://www.hartparroliver.org/

Verty British in style and content, http://tractors.wikia.com/wiki/Oliver_70 says the engine was an Oliver Waukesha design.

http://www.oliverinformation.com/news/1-3.html says the engines in several prewar models were Waukeshas.

The Oliver 70 brochure at: http://www.antiquefarming.com/PDF/oliver_70.pdf doesn't seem to say who made the engine though it shows off many design details.

http://www.agkits.com/Oliver-Engine-Model.aspx says the 60 gas used a Waukesha engine but the 70 gas used a Continental model DS202. It says only the Oliver 44, Super 44, and 440 also used Continental F140, all the other Olivers from 44 through 880 used Waukesha engines.

The most authoritative place to find out for sure is the Floyd County Historical Society that has the Oliver factory drawings and manauls, some for sale at:

At the Floyd CO musuem there are a couple special Oliver engines made to be very efficient on 110 or so octane gasoline. They couldn't convince oil companies to make good enough gas for using them on the farm so gave up the idea. One is in a tractor, one is just the engine on the museum floor.

One of the links claimed about 130 Oliver 70s were sold with a Buda engine but only a few remain.

While that one list said a Continental model, the brochure says there were two engines, one for good gasoline labeled HC and one for distillate labeled ZC. Though it would be more logical to have been LC for distillate. Maybe I remember wrong. I'd think the two compression ratio engines would have different model nunbers even if only the pistons or heads were different if purchased engines. If made in house they might not.

Lots of tractor makers haven't yet made an engine of their own, and both Waukesha and Continental made a big business of custom engines for farm applications, along with Perkins, Hercules, GM, and Buda. And a few Chrysler engines were used too. Seems to me that buying an engine, even if it had to be custom made, made a lot of sense for any maker planning on building under 100,000 tractors or so, because buying the engine effectively cut the tractor development time in half and doubled the engineering staff and time to market was always a benefit in marketing except when the market was totally gone in the depression years. But then some managment knew they had the perfect engine even if it hadn't yet been built and so wouldn't look outside beyond a few for prototypes, like the AC B and WC.

while we are on olivers,does anyone know where I could get a manifold for a oliver 90?

Try Korves Oliver. If they don't have one, they will probably be able to steer you in the right direction. Also ask on the HPOCA (Hart-Parr Oliver Collectors Association) web site.
