If it was fun to pull in LOW gear, I could have a John Deere.
Real pullers don't have speed limits.
If you can't make it GO... make it SHINY

Paul, i think that was Deans original question... In YOUR photo, the oil comes out of the filter thru a tube and goes back INTO the block at the #2 cam bearing to lube it.... In DEANS photo, the block at the #2 cam bearing has no drilled hole, so that block is setup for the BYPASS system and the cam bearing is lubed thru the hollow cam from the pump.. ? RIGHT ?

It would probably be easy, However it would need to be done to a bare block instead of an assembled engine. Because of the need to clean out the drilling and tapping shavings. The second center cam bearing port would need to be drilled and tapped. The Full flow pump, filter base and oil lines would be needed. The filter drain hole could be plugged like the factory with a steel ball, or as simple as a piece of gasket material behind the filter base .

I'm not so sure I couldn't drill/tap/plug a block like that to convert it to full flow style. Done several W-series, but I haven't ever looked at a G138/G149 to see what it looks like inside. It would take a full-flow oil pump, filter base and 3/8" lines/fittings to complete once the block/cam passages were modified.

OK... i was thinking about the oval hole in the filter housing.. I thought the hole in the block was bigger than that pictured .... maybe not.

It's the same as your BE/CE engines. Engine oil from the cotton string filter dribbles thru the small hole in the block into the camshaft area.

DR... so looking at the 149 BLOCK in the photo above, it has a very small DRAIN BACK from the filter............ you think it is not the "old version" ??? I dont know, just asking.. looks entirely different than my CE motors.

D-10-12-14's were old school cotton string filter that bypassed the oil flow. ALL D-15's (G149 or G160) were always full-flow oiling with the Fram PH-8A filter. This is the way they were when built. 60 yrs later, who knows.

Does the tractor use the BYPASS filter or is it a PH8 Full flow ? In the picture, the drain hole between the filter block mounts looks very small for a BYPASS system.... the 149 block changed sometime between the D15 series 1 and series 2 i think ?

Dean, on the B-C motor , the cam was hollow and lubed INTERNAL , and no need for the external port on the block....... assuming you have the old cotton packed oil filter (BYPASS).

Good Morning, We have a block from a 621 forklift (149CID) that only has the one oil hole in the side of the block. The picture shows a D-10 block for sale on the 'net.
Does anyone have a lube oil flow diagram for this engine. I am just about at my wit's end trying to figure out how the engine got lube before we took it apart. There
is supposed to be an internal passage that connects to the hole drilled into the block between the bolt holes in the filter base, which then gets to the center cam bearing passage. Am I thinking right or am I missing something. They may have to come get
me with the butterfly nets, if I can't figure this out.  The block we have does NOT have an opening to connect from the oil filter passage inside the block.
