John - what's a ladder sump? I googled the term, but didn't get anything useful... Right, did someone say "finished"? No? Good, doesn't do to jump the gun eh.... I got a decent session in today & finished cutting & deburring all the fins. I then test-fitted it to the engine (easy peasy with the slightly enlarged holes, the bolts all wiggled into place nicely). I also test-fitted it to the gearbox & did my best to mark the location of the holes for the other 2 gearbox mounting bolts. I'm not sure I got them spot on, might have to do that job again (and it's a horrid job. Final weight, after finning, is 12.4kg... a whole kilo of swarf today! Eeek! No action shots today, you've seen 'em all before, but here's the result: I gave the engine a full turn with a spanner (surprisingly hard work, it's no wonder starter motors take so much juice), to confirm that nothing inside hits anything in the sump (now that would have been embarrassing!) The last picture shows one of the (mercifully few) warts: Whilst milling the counterbore for the outer cap-head (the empty hole at the edge of the curved piece), the angle plate collapsed. How the cutter didn't break I'll never know... Next time, must remember to firmly bolt up the angle plate before milling... :palm: Also, the trial fit threw up another minor issue - the front 2 bolts under the spigots will need to be counterbored, otherwise they take up room needed by the pipework... Not a problem, as there's nothing underneath those bolts, so I can easily counterbore 10mm or so. So, outstanding jobs: - Drill/tap for the 2 gearbox mounting holes - Counterbore 2 mounting holes at the front - Cut relief for jubilee clip near inboard spigot - General clean-up & degrease - Loctite up the end piece bolts (they'll never come off after that) I would have finished today, if it wasn't for the pesky family inviting me to dinner... but I can't refuse free food... :lol: So... is this the penultimate post? Tune in tomorrow @ 10pm to find out... :coffee: |
