Oil pressure on 1950? VAC

the pressure is regulated in the filter base by a relief spring. this can be shimmed to increase pressure if desired (by washers or shims). just dont exceed 25 psi. you may find the engine seals cant handle the pressure or volume and the engine will leak from the crankshaft seals.

the original Case gauges were only rated @ 30-40 psi anyway so 12-20psi is adequate for the low hp motor (12-15hp).

good luck!

the continental engine co. was supplying engines to some tractor manufacturers during war time (i.e. massey harris) because many engine builders had contracts w/ the american armed forces so most engine manufacturers werent producing for the general public. when case came out with the model V most of the parts were built by outside sources. the engines were built by continental (flat head style) the transaxle gears were supplied by the clark transmission and gear co. although the case for the transaxle and the rest of the tractor was manufactured by case. the model V was in production for 2 1/2 years (1940-42). then midway through the '42 model year, case upgraded the design of the V and renamed it the VA. case then took over manufacture of the transaxles and initially commissioned continental to build the engines to their specifications (OHV style). after about a year or so, case had finally upgraded their Rock Island plant to build the engines for the VA and purchased the patents and rights from continental.

now to answer your question.

i suspect that because you have a cartrige type oil fiter, it might be the older continental built engine in your VAC. however if im wrong, if you look on the lower end of the block casting you may find the case eagle on a globe (thats old abe) and a case part # (i.e. VT-###) if its the continental engine it may not have old abe cast into the block. sounds like its older than 1950.
if you can find the engine serial # located on the top left corner on the right side of the engine (from the drivers perspective) just beneath the head, someone may be able to help you with when the engine was built and that would give you an approximate timeframe.

good luck!

The oil filter is an optional shunt system. Being a shunt it will drop the oil press 1-4 psi depending on wear conditions above. If you are going to install the filter, be sure the inlet tube is still present in the housing. The tube is about 2-3/4" long with 2 orifices on the end that directs oil to the top of the filter media. If the inlet tube is missing, the oil will bypass the filter media and drop directly back into the sump and may lower the oil press & volume enough to cause damage to the valve running gear and especially the cam brgs.
