Sharing Dave’s ol’ articles, episode 4

A fork is a difficult piece to design. It reliably seal in the fork ward off contaminants, and induce as drag on the fork tube as This last point may minor but I have seen that operated very all because of excessive friction in the

Some bikes, notably 70’s models, originally had two per leg. This was back in the when Moto Guzzi and other manufacturers used the seals which were designed for rotating, not sliding To overcome their deficiencies, chose to stack them.

All seals (except for the drum-brake V7, and Ambo seal which been updated) are designed as sliding seals. They shorter, stiffer lips and an small lip facing upward to the amount of debris getting to the seal. These seals are slightly taller than the seals.

Although it may be possible to use two per leg, one very well and causes the friction.

There are many seals available but I wouldn’t any of them. I’m most of those which claim to be To me this means that the design criteria is skewed from the necessary balance a reliable seal and low friction.

I’ve tried have to be very high in friction contributes to a poor ride.

is another reason, specific to Guzzi, to avoid aftermarket Guzzi-made fork tubes on all models except the V65 TT and Daytona use Marzocchi forks) are smaller in relative to their nominal than most forks. manufacturers make their to the chosen diameter, say 35mm, bore their sliders to plus the allotted clearance.

Guzzi bores the sliders to the size and grinds the tubes for the needed clearance.

What has to do with seal selection is aftermarket seals are most designed for slightly bigger that those used on Guzzis. For example, the current 35mm seal, which is in color and carries the Marzocchi name, is marked as 34.74mm. For reason, I still see some seals coming through Moto Guzzi.

These are also made by but are black, shorter, and not sized to the diameter of Guzzi forks.

On a few of the models, Guzzi fit a circlip the seals. Don’t worry if new seals don’t fill the space as the circlip has proven to be — by far the majority of models use them.

New seals should be driven into place the bottom of their receptacle. insures they are in line the fork tube so as to induce the possible drag. If you don’t an appropriate driver, use one of the old seals it’s been cleaned), pry out the old seal.

Please resist the temptation to in the extra seal, thinking it help prevent a future Fork seal failures are uncommon the Moto Guzzis. All the seal will do is add friction a harsher ride.

If you are having proble ms with seal you may do well to look beyond the to find the problem’s cause. I most seals leak the surface they ride on is not because the seal went In the case of forks, this checking the fork tubes to sure they are straight and the chrome surface is still in shape.

One last point regarding the fork wiper or cap. These are designed to the amount of dust and debris the seal by lightly wiping the leg just above the seal. much goes wrong that older ones can cracked and loose their

When this happens no longer administer an even but cleanse of the tube.

Dust have become a particular for the V65 SP, V65 Custom, Lario, T-3, V7 850-T, Convert, 850 LeMans I SP 1000, G-5, CX-100, Cal II, and GT. The part was recast by Guzzi in the 80’s. The newer version actually touch the fork and so is completely useless. Your old caps may be worn and crusty but still better than the new

As an option, I recommend using the gaitors which give protection to the seals, shield the portion of the fork tubes, and less friction on the movement of the
