Turns out it's now a drip drip drip and pretty oily when I stuck my finger in the hole. I noticed some last year coming out the bottom most bolt that holds the bell onto the gear casing. Didn't realize it's probably been there all along after getting the bike back.
If it is the pushrod seals, and it is a significant dripping, the clutch plates would be soaked and slipping.Most likely engine oil from the rear main seal or such.
Ed did all new seals in tear down so I'm told. I'm pretty certain its gear oil but will double check from what you say Wayne. I use synthetic strawberry shake in mine. Have had a little weep since getting the bike from Ed. Has about 1000 miles since done. Haven't seen anything since the beginning of this season until it say this past week, then a smudge under the bike like it seemed to do last year. I pulled the rubber bung and stuck my finger along the inside of the bell housing and got some good oily residue on my finger that I also saw on the bung inside. No clutch slipping. Flywheel looks dry. Leave it and watch it for awhile? It's new, so...
So once you stuck your finger in it, why didn't you sniff it? ~; ;D
This is why I use Bel Ray gear oil. Passes the smell test and it's RED.
Kev, a bit of background. Some time ago myself, NolaGuzzi and Nick Webb all had gearbox troubles. nick and Nola had pre-selector problems, mine shed the hardening on 5th on a longish sort of trip. We found that Senor Whitegloves on the official Guzzi site on how to take things apart used a technique that did not work (because Guzzi quietly rectified a fault with the pre-selector and kept it quiet).The three of us worked our way around the problems that Guzzi don't mention and Nick wrote a very informative, and very humorous real-world thing on how to get the box apart, and how to put it back together.This can be found on Greg Bender's site "This Old Tractor" under 'Breva 750 Gearbox Repair'. Plenty of photos etc.The main seal is situated behind the casting that mates to the gearbox case. The most difficult thing is how to undo the large nut on the front of the transfer shaft. Steamdriven and myself fabricated a splined spanner with a 600mm long handle to hold the shaft that goes in to the clutch, from a burnt out clutch sent by Pete R. Cut the centre from the clutch and there is the basis of your spanner. The handle is demountable so that it can be sent to Oz if Pete ever needs one. Also, a spanner welded to a handle that actually fits the nut, and another large piece of steel with a couple of holes that match the holes on the front of that casting that attaches to the gearbox. that nut is, we have found, usually torqued to 10 zillion foot/pounds. ::) I think there are actually two pushrod seals, one behind the Thorington bearing that the clutch throw-out lever works on, and one in the front of the box.Other than that, it's all easy. ;) :-\
The good news is that every time you take a Guzzi apart, the job gets easier…cr
