T3 oil pressure lines to the rocker covers.

[falcone]

Just fired up my T3 which had a professional rebuild a while back but not had time to put in to service until now. With the rocker covers off, the left hand side seems to have plenty of oil squirting out, the other side in comparison seemingly almost nothing? I took the rockers off and had a look and all seems fine. No blockages anywhere, everything lining up and oil comes up the pressure lines on both sides. How much oil should come out??? Is there a reason for the discrepancy?

Nah, should be similar amounts. Someone hasn't put longer rocker spindle retaining bolts in the LH side have they?

Thanks Pete. I doubt it, the professional specialises in Guzzi's and came highly recommended, but probably worth looking at the left hand side. I only took the right hand rockers off to inspect as they were giving out the very little, almost, no oil. I thought they perhaps should be more like the left side and squirting the oil out? How much oil should come out. The left hand was throwing it out so that I soon turned off! This was at barely more than tickover.

If its the rubber type lines to the head the inside of the rubber hose may have detereated and the inside is blocked. They come apart easily just pull the hose and it should come off just replace with some oil resistant  hose and see if the flow matches the other side .My friend had the oil pipe blow off while in upstate New Hampshire -fix was a piece of rubber tubing the he carried for repairing a leaking hose on his convert. Just saying
As a side note I replaced the feed lines to the heads with the metal type from a Ambo /Eldo .
This was on my Convert and just bolts on.
Remember that the metal piping goes back to the original V7 so this is a proven system

Thanks Tomb. No, is the stainless type I have fitted.

    Also check that there are no chunks of debris inside of the rocker shaft-seen it happen. And teflon lines are the clear shi$$ compared to the rubbery ones of any type, well worth the couple bucks extra.

Thanks acogoff will definitely look. I am a self confessed worrier when it comes to my bikes. About to go out now and have a look at the l/h rocker assembly.

[falcone]

Mind you have to be pretty obvious to spot something :-)

[falcone]

These are pictures when just run for a few moments. They were both clean before hand... Again the l/h has plenty of oil the r/h seemingly nothing?

Pull the rocker shaft retaining bolts, make sure they aren't too long. If they go too deep into the rocker shaft, they'll block the passage. I use a m6x12 with a split lock washer.

IMO, 12 mm is just a little too short, 14 mm engages more threads and doesn't block the passage.

OK but, I think 13mm would be best


This is a 12 mm with a compressed split lock.

     You could pull the banjo and put the hose in a container an run it a bit to get an idea as to how much flow gets there. A hose can go bad or even be bad when new.

[falcone]

Many thanks for the suggestions Joe W Antiem Cycles and acogoff. Taking the banjos off and running in to a container is my next step. I'll check the rockers as well. Thanks

Well? What did you find?
