Hello forum,
On the subject of Ceriani forks, can anyone recommend a preferred seal or kit for rebuilding 38 MM forks for a 77 3CL? Plans are to  upgrade the internals with Race Tech springs and emulators, and saw this option online. They mention this eliminates the need to double up the seals. Any thoughts?

Also, is it safe to say that all 1974 SF 750s have 35MM Ceriani forks?

Thanks,
Bob

No.

It may be safe to say all drum-braked 750s have 35mm forks.  During the transition from SF1 to SF2, a few bikes were fitted with 35mm forks and disc brakes, later bikes had 38mm forks.  These first SF2s still carried the SF1 DGM homologation number.

I connect to this tread to ask if the seal of this link http://www.tagoscooter.com/generici/483_ricambi_universali/kit_paraolio_forcella/9631_kit_paraolio_forcella_-_35_x_47_x_79__-_ariete_cod_ari012_-_prezzo_per_coppia.php is suitable for ceriani fork 35 mm
The 7/9 value should indicate the double lip.
Obviously monterei two seals on each side


I disassembled the old Corteco marked with BAU3SL 35-47-7 but are obviously out of production  :(
 
I use fork seals intended for Jap dirtbikes in 38x50, pretty sure currently x10.5 but anything less than 14mm overall height. Twin lip with a wiper above. I just tap them in until the circlip can fit, no spacers or anything. Never had a problem and they last really well. A damn sight cheaper than that advertised price you showed.
 
Thanks Tippie, but you have the forks 38 mm, I will mount the 35mm.

I understand that the height is still not a problem and can be mounted even those from 14 mm.
In this case one for each side, right?
 
the internal circlip on 35mm forks is unusual shape with a ridge.

Is this unique to Ceriani, or will a normal internal circlip  do - unluckly both of my circlips broke so not sure what size is it? 46,47, 48mm....?

some of the internal circlips have tabs large enough to foul the fork tube
simpy mind your selection
i'd think a diameter similar to the OD of the fork seal would suit

cheers,

The circlips in my 38mm Ceriani had such large tabs that they fouled the dust lip of the Ariete twin lip seal. Had to cut off the dust lip on the upper seal to get things in working order. Quite a fiddly job with the seals already in place, so I'd recommend to check this before installing the seals...
