Parts!

Here's some of the parts I've bought for the engine rebuild.



You can see a gasket set, oil seal set, large engine mounts, long engine mount bar, clutch discs and plates, chain guides, shims, o-rings, nuts and bolts and the rear bearing. For a lot of these parts I would normally nip round the corner to my local scooter shop Fanatic Scooters but I chose to rebuild my engine in the month of the year that they close! So I used MB Developments (or www.lambrettaspares.com) and Scooter Restorations. MB's delivery is speedy and efficient, but Scooter Restorations closed over the Christmas period and then they were let down by FedEx's glacial service, so my stuff took 18 days to arrive. On the plus side they did give me a nice free mug, and my orders since have been very quick.

For the end plate gear cluster bearing (6004 SKF), the drive-side bearing (6305 SKF) and the flywheel-side crankshaft bearing (NU205 ECP SKF Roller Bearing) I went to bearingboys.co.uk, where I saved myself a good few quid instead of using the lambretta specialists. There are lots of direct bearing suppliers on the web so it's worth shopping around.

Cleaning parts and casing

Now its all virtually stripped down its time to take stock and clean. I removed old gaskets from the casing using a screwdriver and sometimes a chisel, taking care not to damage the surface. Then I used a wire brush attachment on a drill to clean the outer casing.



Then I cleaned the whole lot, inside and out with an engine degreasant called 'Gunk', and then washed it all off with warm soapy water.

Some of the parts that were due to be refitted I gunked, washed with warm soapy water, and then ran them through the Zanussi parts washer that we happen to have in our kitchen:

Tip: don't do this. Your parts will end up nice and clean, your dishwasher won't. I spent longer cleaning the dishwasher than I would have cleaning the parts properly :)
