3MO LC776 Gearbox Fitting
Part 2 – Dry Sump Tank and gearbox oil cooler pump bracket
With the 3MO gearbox being slightly fatter (although shorter) than the standard JC5 the previous bracket for the drysump oil tank clashes with the gearbox. So the tank needs moving up, And to give more room for the shifter linkage will move it outboard slightly too. Very similar idea to the previous bracket but just moves the position.
Already had a CAD model of the previous bracket so could use this as a template for the new one. Had already scanned the chassis leg and gearbox for the gearbox mount. So can use this as a guide to make sure the new bracket clears the gearbox.
The old print and trace method at work again. Would love to have access to a laser cutter!
With the pieces cut out I mocked it up on the car to check the tank was going to work in the place before welding it together. The return port on the tank was going to get rather close to the strut brace so needed to make sure this would actually clear.
The feed line port originally came out of the RHS on the tank (LHS in picture). This was fine with the standard gearbox but this is right in the way of the linkage for the 3MO gearbox. So a bit of head scratching but have a plan! As the tank is a splitable tank the bottom section can be rotated. Therefore my plan was to rotate the bottom 90 degrees so the feed line would come out the front.
Bracket welded up and now time to have a sort of the tank and see if its going to work.
Took the tank apart and gave it a clean out. Wasn’t particularly dirty but just has a bit of black oil residue sat in the bottom. Was also pretty cool to see exactly how the tanks are put together with the internal baffles. Tank back together with the base rotated 90 degrees.
Think this feed port position will be much better for the hose routing. But won’t be doing the hoses until later on but have to think how and where the hoses run.
