OuchSorry for your loss…that seems pretty destructive On the bright side we’re getting tons of used V7’s coming up for sale usedBuy a motor and slap it in? I’m not sure rebuilding would be cost effective…I’d hate to see just the parts cost to repair
Not too sure I understand your phrasing about 'moving up and down the crankshaft' ? Is this front to back orup and down ?
After chatting it up with a few mechanic friends, and reading your thoughts, I don’t have the money for a rebuild job, and I don’t see any good V7 II motors available. Just listed it. And salty liquid escaped my eye.
I’m sorry Dirk.
Not sure how many miles you had on your 2016 V-7ii? Still sounds like the same crank issue as all the other lucky ones. I still have not got a answer from Guzzi my 2000 mile engine in my Stornello.. (Crank thrust issue) Once it happened I went right to ebay and picked up a good 4000 mile 2016 ViiIf Guzzi helps me on my engine..(50/50 chance I would think) I will have one engine the good engine for sale. You can have first crack at it, and fo what I paid.. $1089.00 Just a thought...
I have a couple promising leads to a replacement motor. Trying to jump on whichever one I can get ahold of first without breaking the bank.One of the potential purchases is a V7 II motor that had the infamous crankshaft issue. There’s also a used crankshaft available on eBay taken off a salvage bike. Assuming this bike didn’t suffer that bad batch issue, I figure I could purchase the crankshaft, new bearings, and put it all together myself, right? That said, I’m not fully sure on what I’m doing. Would I have to rebalance the crankshaft, and at what point? Are there other clearances, specs etc., not found in the service manual that I’d have to be mindful of? Anyone have any good links for home engine repair?Thanks!
If I remember correctly it's the thrust bearing/shim that was not right on those engines.
No, you should not have to rebalance the crank. These technical training videos may help. The B750 isn't much different than your engine.https://www.thisoldtractor.com/moto_guzzi_technical_training_videos_eng.html
I’ve chatted with a few respectful dealers that we all know and love, and there doesn’t appear to be complete agreement as far as what exactl. Some say undersized crank. Needless to say, once put back together, I may ride it for another year, but not much longer.Thanks, Charlie. I keep forgetting that Greg has service videos uploaded.Before purchasing a new (or gently used) crankshaft, I guess I can inspect mine. Is it easy to tell if a crankshaft is damaged? Score marks? Do I only worry about severe scoring, or are scratches that I can’t even feel going to be troublesome?
And yes—I do realize that there’s a high chance that a naive amateur such as myself might think I have it all together and in spec, and install the engine and turn her on, only to hear chakka chakka chakka chakka BLURBADA BLURBADA BLURBA RETCHETA RETCHETA PBBBBBBTTTTttt.
DUDE, You're going through all this trouble and Mark Etheridge just bought a brand new crate motor for a 2016 Racer for only $2500!?!
Mark has more money than me at the moment.Funds are tight thanks to the other work I’ve had done (and the sidecar stuff).If I take my time, this rebuild will cost under $1300 and bump my knowledge and experience up.
JMHO, I don't think they designed the bottom end to be rebuilt on the V7. I hope it works for you.
