[QUOTE="Vincent Brake, post: 86318, member: 398"] Hi there, anybody got ideas about the oilsystem in the engine?? (i know Herve Harmon ones) I am recovering a well worn set of cases, (Most welding is done now, new Main bearing housing) and am trying to make it into an ultimate engine. ONE: with a bendix starter under the big primary sprocket with a Z=74 gearwheel to be driven by starter, i needed to make me a flat gearbox cover G2 (layshaft bearing moved inwards, done with roller bearing, one side axial trust), thats the easy job done. TWO: a better oil system with a wet sump under the engine, to contain about 4 l oil, oil drain connected from the scavenge chamber, by an 1" hole. (it wont be THAT visible) Now I was thinking putting in a Japanese oilpump to drive from the large idler, but have no idea which?? I can weld up a oil pump housing in the timing chest, with a suction pipe down; either outside or inside through the big hole. Through a modified timing cover one can make the feeds and even retain the original oilfilter (agian bit of welding etc.) and also from the top of the oil yet OP39 a pipe to the rockers, so no more unfilterd oil. and have a two bar yet of oil on those terrible cam folowers (DLC coating) and bronze bushes.I align the holes in the megacycle cams with the spindles (they need new bushes than) Spindles Et.All made from Boehler K340 and nitrided. The whole excersise is making it OK for even a 200.000 Miles life, with oil changes like my car (about none) Its all to go into a egli style frame set for touring. 5 speed close ratio, surtees, TPV 90 mm (or is it 92) set on 8,5~9:1, 38 mm Ceriani, double API Lockheeds brake, own rear hub. it will take a while but it can be done. Vincent S any ideas about that oil system? or about the rest. (apart from I am mad, thats no news)[ATTACH=full]17360[/ATTACH] [ATTACH=full]17361[/ATTACH] [/QUOTE]
