T140 D (1982) Bought For Restoration.

Hey Manin.
Thanks for your input.
I have a complete parts manual, and the workshop manual on it’s way!
It looks like the cam gears need to be pulled from the cam shafts, and then the shafts can be removed by sliding out to the drive side now that the LH casing has been removed.
On a footnote, the shells in the big end, and the journals on the crank look perfect! I will still replace the shells, rings etc on rebuild...

 

Thanks again Martin.
I have now received the correct socket for the LH cam gear nut (what a very odd size - 1.1 inch = 28 mm!), and as the crankcases need replacing, they do indeed need to be removed… The corrosion in the lower part of this bike is a nightmare: lower engine mounting shaft and spacers totally seized in frame, spacers and crankcases; frame pitted, rust on one part of rims, and even the RH fork to spindle clamp still requires work (and heat) to remove it fully. Had I seen/realised just how bad it was, I probably should have driven away or dumped en route home!! Not giving up now though..!

 

OK. Camshafts out much easier than I expected.
Piston and oil rings removed from pistons - they were stuck in the grooves so came out in many pieces
Have just managed to remove the sludge trap screw from the crank, with massive difficulty! Bought 12 mm screwdriver bits for a manual impact driver - no go. Air pressure impact gun - no go. Weld a washer and nut onto the top of the screw - no go! Finally drilled a 10mm dia hole into the screw and used a hand LH stud extractor - success!
Next stage is cleaning the aluminium engine parts and iron barrel, then the frame and swinging arm…
Almost beginning to be good fun...

 

Next obstacle…
Now that the sludge trap screw has been removed, and the bolt in the crank which locks the sludge tube in place, it should pull out using a hook quite simply?
Nope. Pull as I may, it doesn’t want to play.
Anyone have any ideas/tips how to get the tube out?

Thanks for any help...
