V7 Sump Extender

[ponti_33609]

I installed a sump extender this past Friday.

Very easy to do.  I work extremely slow and this took me 2.5 hours which included clean-up and old oil disposal at the local auto-parts store.

- Front and Rear Oil Drain Bolts are Different Sizes.
- The canister on the rear makes that bolt a bit more difficult to get to.
- Pay attention to not lose any of the washers on the plugs and o-rings on the dip-stick and oil filter cover.
- Use anti-seize on the stainless hardware
- I was able to re-use the installed gasket
- Only get the bolts to begin to catch on the re-install and get them all started. 




There is much discussion if this sump is needed.  It for sure isn't but I feel better having more oil in the bike. 

There are also a few folks that make these.  I got the GT model as I had a credit with AF1 and this is the one they sell.  I like that it is finned and already black as well.  GuzziPower also makes a version and I see one for about 20% less that is sold on eBay that comes from overseas.

The finning probably doesn't do much, but looks nice.

When installing the one I got from Guzzi Power (I felt like in the bad break-up that was his) I seem to remember that it was important to just thread all the bolts before seating the spacer, then to seat it and run the bolt the rest of the way in but taking care not to let the spacer get cocked slightly or the bolts would bind.

For sure....not sure the fins do anything but like the look.

I get the idea of having more oil in the bike...cooling, if it's needed.  Did anyone ever try to measure the difference in cooling?  Is the oil pick up also extended?  Otherwise, I don't really get the point of this.  I mean you are extending the part of the sump you can't access.  I'm sure I will be enlightened (or someone will at least try...).

No, you're not extending the part of the sump you can't access as I believe the pickup is in the bottom of the sump.

Even if it doesn't directly effect temperatures more oil still means higher volume of additive package to resist acids and general deterioration of the oil.

Also, the 2TB smallblocks immediately prior to the 1TB models sometimes suffered from a sudden loss/consumption of most/all oil leading to catastrophic failures. Now it seems the 1TB models have solved this (perhaps it has something to do with the revised breather system), but it's still a nice piece of mind to know you've got more capacity should too much of it start winding up in the breathers and being drawn in and burned instead of returned to the sump.

having seen a 1tb engine badly damaged when the already vulnerable low sump was made even lower with a spacer and then damaged id send it back and check my oil more regularly.


In the UK guzzi club we have a 100000 miles Nevada that has done just fine with 2l of oil

I guess that would only matter if one rides roads (dirt or really bad pavement) that would risk such things.

I can't imagine that anywhere I've ridden for decades.

How does the pick-up move down with the sump...?

Because the pick-up IS part of the sump incorporated into the bottom of the sump so the passages are extended by the spacer.

It's not like a typical automotive motor where a pick-up is bolted to the underside of the block and hanging down into the oil pan.

[v65tt]

The 'pickup' is part of the sump casting with a gauze bolted to it

The spacer has drillings in it to allow the oil through

And a 100,0000 mile V7C  with 1.7 L - which uses an extra 500ml or so between oil changes. (And I think I may have missed my last membership renewal to the UK club - will have to check).

They do a really good job at catching the dirt and grime.

Quick hose off.   

I agree too that this is prob not necessary in the least...I just feel better having a bit more oil.

How pick-up actually occur at startup? Oil pump is located much higher so eventually all oil will return back to sump, right? Does this means that few seconds right after start engine is not lubricated properly?

Or jumping curbs to go around garbage trucks block the one way streets...

Some of the topes (speed bumps) I've ridden over in Mexico would have me worried with the extender in place.  I had one on the bike but took it off before heading south of the border and I'm glad I did.  Most topes are fine but the ones I ran into (or over in this case) in Guerro Negro, Baja were high and steep.  If I get back there I think I'll try to get a picture of my V7 straddling one to see if my perception of clearance meets reality.  Most other topes were pretty tame height wise but they sometimes put them in crazy places and most have loose gravel leading to them, closest I came to dropping the bike was trying to slow for a surprise tope near Mulege and losing the front on all the gravel in the road.

I'm not sure there is any pavement in the US I'd worry about though.

Bingo.

Interesting point, but the 750 is one of Guzzi's oldest designs (maybe The Oldest), so if it's been ok for all those decades, it should be good.
