The sludge trap was about 1/8th full.   The sludge trap threaded plug turned out with no resistance!

These are the engine assembly errors I have found which occurred at about 100k miles which was 30k miles ago.

Sludge trap threaded plug - loose, no Loctite.

When replacing rings the Nigusil plated barrels were severely cross hatch honed leaving deep hatch marks.  Honing of Nigusil barrels is not recommended when replacing rings.  Certainly not with such a coarse stone.  Oil consumption must have went up after that hone job!



Hollow dowel tubes missing from both front and rear main bearings.   Since the dowels major purpose in life is serving as an anti-rotation device for the bearings leaving them out is risking a total loss of oil to the crankshaft if the bearings turn slightly.   

Rear main bearing was installed with sealant on all surfaces!  This made removal of the main rear bearing much more difficult than necessary! 

When last removing the rotor a soft piece of metal was used in the crank to push the rotor off instead of the proper hardened piece.  This wedged the soft piece in the crankshaft.  Rather than take the extra time to extract the soft piece the rotor bolt threads were shortened!  It only required 10 minutes to set up the crankshaft in my drill press to drill a pilot hole and remove the piece with an Easy Out. 



A substantial amount of sludge was found in the pan.  One of the pan socket head bolts had the "socket" rounded to the point it was useless.  The bolt required extraction with judicious use of a sharp punch to get it to move.  I am betting that the pan hadn't been dropped since the "overhaul" due to this bolt.

The oil filter was loose enough that a toddler could have turned it.  This filter definitely could have benefited from the hose clamp safety feature, but it wasn't present.  Another near miss avoided! 

And!!  Orings were present on every cylinder head stud at the base gasket instead of the required 2 at 12 and 6 o'clock.  I guess the mechanic thought more was better!   :rolleyes:

Going together.  The old adjustable fixed timing chain tensioner replaced by a modern "automatic" adjuster with a new chain.

I always appreciate the simple, but elegant engineering that went into the Guzzi V twin.   I was fairly experienced overhauling Harley engines before I attempted my first Guzzi.  I was amazed at how simple the engines are to overhaul.   That simplicity does not come by accident.  The design is an inspired one.

I am sure Charlie has seen many worse but this is the grimiest Guzzi I have seen.

That was pretty bad, just missing a bunch of mud/oil mix caked between the fins!  :grin:

I found one more assembly error by the shop that did the 100k mile "overhaul".   

I had marked the flywheel before I removed it for easy reassembly.  When I installed the flywheel this afternoon I double checked to make sure it was in the right position. The shop had assembled it 180 degrees off!   I am scratching my head trying to figure out how they timed the engine!!

I went through the heads.  They were in great shape.  I good cleanup and they are ready to go. 

The exhaust studs did need replacing though.



I assembled the valve train but decided the wear on the rocker pivot shafts was enough to warrant replacement.  Hopefully I can button up the top end by the end of week.

I backed up a bit and removed the flywheel to add some JB Weld to the top freeze plug.

Ok, I give up. What is this a picture of?  Something to do with the crankshaft sludge trap...

That's what the solidified sludge looks like when you remove it.  Very normal amount. 

And it collects in here.

Ive been around engines my whole life, and never seen one before. Is this common in any other engines? Is it open to the oil gallerys, and CF just flings the heavy junk out?

Correct the centrifugal force causes the particles to be forced against the wall of the sludge trap and those that manage to stick don't pass through with the oil. 

With non oil filter Guzzis this is the only "filtration" available.  Most old Brit engines use this method.  All old Triumphs have sludge traps in the crank.  Many old Hondas like the CB350 have a oil slinger that operates the same way.  My 66 BMW R69S has an oil slinger that collect the sludge.  This is the only filtration method used on older BMWs, and I am sure many more.

Got it. Didn't think the sludge would form a solid mass; I thought it would be more like mud that has to be rinsed out...

I'm not a regular on this forum and only just found this Restoration section.  Man, there's some great stuff on here!  I'm enjoying this particular thread Dave as I did a bit of light refurbishment to a T3 Cali in 2016.  Rather stupidly I let one of my friends talk me into selling it to him last year and I replaced it with a V85TT, which really wasn't what I needed.  I do love the T3 Cali.  Looks like it should handle like a canal barge, but has a wonderful nimble chassis.  I look forward to seeing the final result!
Cheers,
Derek

Derek,  we certainly started at about the same point.  Light refurbishment indeed!!    I will be happy if mine turns out as well!  I just love the look of the T3 California.   All the bric a brac but still has all the qualities of the early Tontis.

I wasn't sure if I could salvage the front rim. 

This is how it looked after an aggressive scrub in the solvent tank.



After working my fingers to the bone for a few hours today this is the result.   I was thinking about throwing in the towel and sending the hub to Buchanan to have a nice, new Borrani laced up.  But dodged that expense.   I am retired now so I have more time than money.

That's a great job!  I would have sent them for vapour blasting to get them clean and tried polishing from there, but thought of hand polishing those awkward profiles puts me off.  On my T3 the wheel builder mechanically polished the rims, but didn't get the best result.

The rear rim went faster.  I was able to start with 2000 grit and then polishing compound.  I was able to finish it while listening to disc 2 of the Allman Brothers at Filmore East which is over 1 hour long.   Mountain Jam being one of the best songs to listen to while polishing known to man.   :cheesy:

I still have 80 spokes and nipples to polish, but the befores and afters are pretty dramatic.

As with most of my restorations the level I aim for is what a very well cared for machine might look like after 40 years or more, rather than trying for the "new" look.   I admire those that can accomplish the new look level, but I never seem to have the patience to take it to that level. 

Rear before.
