Hello all. As the title, I am finally about to install my newly built 1600 tp into my '73 lb. It has a cb performance maxi 3 oil pump with dual outlet pump cover. I knew that I would have to modify the rear support bar but kind find any clear pictures of how to do it. I have seen the pics on Mike James post but would like some clearer images. Anyone out there able to help? Cheers John
I have more pictures. Basically create clearance for the pump cover and the oil hoses by cutting the left hand support back until it is flush with the front of the bar, apart from the tube for the fixing bolt that contacts the engine block. I added extra welds to the remainder of the support, on top of the bar as in the process of grinding back, you lose two welded connections to the bar. You could also weld in a flat piece of steel if it worries you. I think I also slightly ground away the outside of the left hand fixing tube for clearance as the hose and fittings hits it otherwise. This is basically to provide a clear path from the angled spigots on the pump cover, with enough room to get hose clamps or other styles of hose termination between the bar and the engine block. This picture has the bar laying as if I were to lift it up from the ground and place it on the back of the engine. Later I shall go and find more pictures.
Yes, it is fairly tight, it is one reason why instead of using swaged on hose ends/ AN style , I ended up with using Jubilee clips with hoses pushed onto barbed spigots fitted to the pump cover, as they are low profile. I double clipped the hose, two clamps per spigot, although actually the hose will not come off once it is on all three barbs and a single hose clamp is stopping it expanding. The barbs do the sealing, the clamp stops it popping off - doesnt have to be very tight in fact. I also use stainless braided hose, as that means the rubber hose cannot expand as much away from the clamp. I bind the hose end in a couple of turns of insulating tape when cutting it to stop the strands fraying back, and that lasts long enough to get it onto the pump, then one of the Jubilee clips takes over the anti-fray job. I swapped out the two hoses a few weeks back, and when I took the clamps off the old hose , I still had to slit the hose then grip it firmly with some pliers to get it to come off the spigots. It showed some surface cracking after about 10 years.
