Before we put the gearbox back in, we grabbed a big piece of plywood and supported the engine with our transmission jack so we could replace the engine mounts. The engine will have to be lifted slightly to free the engine mounts. Normally this is not recommended as you can crush the oil pan but the engine in the Cappuccino is only around 100 lbs so we weren’t too concerned.The new Monster Sport Engine mounts look awesome compared to the rusty old Suzuki mounts. The engine mounts were actually in really good shape for their age, but having new mounts will reduce engine twisting under load so we’re glad we swapped them out.One complaint we have with the Monster Sport kit is it does not include new hardware. Why would we want to put rusty old nuts and washers on our shiny new engine mounts? We instead ordered a few bags of nice strong Grade 5 hardware from McMaster-Carr. With new engine mounts and new lock washers and nuts, our engine should be firmly mounted for years to come.
Finally, we get to the differential. Removing the diff isn’t too hard since, like with everything else in the Cappuccino, it is tiny. With the driveshaft and exhaust already out, draining the oil, unbolting the axles, and removing the speedo sensor are child’s play.
Draining the diff oil is easy enough. The Cappuccino diff uses a pipe thread plug for the drain and a standard bolt and crush washer for the fill plug. Make sure to replace the crush washer to avoid a slow oil leak like we had.
Remove the single 10mm bolt and pull speed the sensor free. Make sure to stuff a rag into the hole so no dirt or debris gets inside. We also zip tied a plastic bag around the dangling sensor so it was not contaminated.
