The other job I got through this weekend was draining the oil from the diff. This was the first time I'd ever done this job on the triumph and I'm pleased to say it went okay! The main problem is that triumph were too penny pinching to fit a drain plug so you have to use a small tube through the filler plug to empty the old oil out. I used a small siphon style hand pump. I just stuck the pipe in the diff, pumped the oil through to get it going and then waited for it to slowly siphon out. Imagine my surprise when I discovered that nearly as much oil came out as should have been in there!
Now I just need to pump some new oil back in. Can anyone out there recommend a good oil for a hard working diff?
In other news this week - The Spitfire Graveyard got back to me saying they'd got a decent heater. Haven't had time to call them back yet, though! Also, I got onto Moss Europe about my alloy bellhousing and found out its going to be with me in a few weeks. That's something to look forward to! Then I can get on with getting the engine out and replacing the clutch.
