California hydro . Service action camshaft... Hydraulic tappets ..Help needed

[rodekyll]

Definitely not the case
Don't know year of change but 96 Cali engine had the wider pump and gears with needle roller bearings so very likely hydro has same or could have.
Only issue I found with late pump was the need to machine (alloy) gear to get it further on, guess the original sprocket was either slightly different offset or chain ran a little offline. Sprocket part number would tell

As RK says, have a look at shells, if they survived, you'll get away with recall kit, chain, maybe sprockets and pump fixed, fingers crossed.
Hope Guzzi give you kit but if not , buying for $125 from MPH sounds reasonable

Thanks for the clarification.  :)  Could the offset be due to the phonic wheel being added behind the cam sprocket?

Could be, was another issue fitting gears from early one, had to grind case to get gear on cam, first time I did it up, it locked tight, original sprocket/phonic hoodiki must have been dished. I have the sprockets somewhere, maybe some early ones too, if I find them I'll take pics to see offsets.
Fitting later pump doable for you anyway, just check clearances.

Hi guys

I forgot to take pictures of oil pump yesterday. After dismantling my pump has been immediately taken by my friend to specialist which can help in this topic. I only remember there were two neddle bearings. Later I will take pictures and  put them here.

FWIW,the difference in pumps is the gear width. 14mm vs 16mm. The pump housing is the same cept for it being machined deeper to accommodate the wider gears, which BTW leaves a very thin wall in the housing where the sprocket driven gear resides. The pump sprockets have the same part# cept for a larger font 30 added. The 30 gear has a 1mm deeper offset. Good luck.

Thanks Dick and Martin.

Adamus, it sounds like as good an outcome as you could hope for. Since the cam bearings aren't damaged, the case is salvageable. Just the same, I would completely strip the engine and carefully clean all oil passages..

I hesitate to join this discussion because you all have so much more expertise than I do.  However, as someone who loved owning a hydro, which I bought at 27,000 miles and sold on at 42,000 miles, without any cam/tappet problems, may I suggest that if your hydro is repairable you ensure the oil pump is good as new, and that you use the correct grade of oil, to avoid the whole thing going wrong again within a few thousand miles.  This is because the usual problems may well be related to oil pressure.  I would also say that my single plate clutch never gave me any problems and was still fine when I sold the bike, so don't panic about that if it's working OK.

Graham..
It is not related to oil grade...camshaft taken out from the engine is totally damaged!it is not only worn out...it is deformed and after closer inspection I found even crack on the top of cam lobe. Anyway guzzi guys from factory know the issue. They try to keep it as a secret.,I have some unofficial information which I can not share now....Monday I will have some news from italy what to do next...if they dont care than I order recall kit +new oil pump (my is not repairable)- from mphcycles I hope. In my machine I have double plate clutch..so at least this :). Al I can say now is that it depends on your drive style..sooner or later my engine without recall kit will explode:)

Hi Everyone!!!

Guess who is back in bussines:) .
Thanks to wildguzzi.com I managed to get in contact with MPH Mike from Houston.
Accidentally my friend was two weeks ago in Houston .so he could pick up complee upgrade kit for me..
I'm happy like a baby now touching new parts form my little darling, which is since one year with broken heart in garage.

It is time to start disasemlby procedure to last screw.

I will update you with pictures from this job.
Special regards to: VascoDG, Rodekyll, MPH_Mike, Pete, and all others who helped me to get to this point.

Cheers .Adam
