Here is everything needed to convert to a high volume oil pump. The pictures would be better if the guy washed the parts.
well guys ... guess what. i took the front high low housing off and drained the oil. ok so i stick my hand under the gear and it felt ..how do i say a swamp in there. so i took the right side wheels off and the gear and pulled the sump and screen out. it was stopped up with about an inch thick of what looked like mud. i pretty sure this wasnt in there at the time of rebuild. it has been sabotaged before the rebuild . but my screen is round and made of brass. the tube is round the end is blocked off with a hole bored in the side. is this factory or has sombody made this.
If it is anything like I've seen, the mud is really mud. There may be some fine metal particles in there but mostly it is dirt that gets sucked in thru the breather over the years. Really bad at it if it is in a clay soil area as the particles are finer. I sometimes wonder if it wouldn't be worthwhile plumbing a line from the filler port to the air cleaner and doing away with the factory style breather cap. Interesting side effect of that would be that the piston would then draw air into the crankcase when the engine is not pulling air for combustion. And force it out when the piston is sucking it in for combustion.Wow! Well at least you found the oiling issue. This is the big down side to having a low pressure, bypass oiling system, the oil is not filtered prior to going to the engine. I'm not sure what your plans are for this tractor but with all the time and money you put into the rebuild it may do you good to disassemble to ensure none if that "mudd" got I to the crank. Is this "mudd" gritty?

Wondering if anyone had started producing oil-pump parts...Gravely Frank,
Mostly what you see on eBay. Exactly what are you looking for? Richard's still has many parts.
Wondering if anyone had started producing oil-pump parts...
When I last checked-into the L oil-pump, back in the mid-1980's, the Gravely agencies told me that parts of the old-style pump were few and far-between, as were the upgrade parts...
At the moment, I don't [think] I need anything, but I have two old-style L's that might need help in that dept, when I get around to them.
So for the time-being, we're scrounging old-stock and used parts for the old-style oil-pump ?
Thanks for pointing out that instruction sheet, I had not seen that before. There is more to it than I thought.
that sounds alot like my 54 gravely. the holes in the rod and the protruding intake cam shaft. and the springs on the valve cages.
Well, I just disassembled the bottom end on my '61 LI to straighten the wobbling crankshaft. This tractor clearly came with the factory high pressure/volume lube system. It has the L-863 connecting rod in it. (The number is stamped in the forging.)
I expected there to be hole in the bottom of the big end of the rod, but there is not one. I thought the hole was part of what allowed greater oil flow. Or is the hole only supposed to be added to the older L-306 rod?
