Marzocchi seal presses

[Odinson]

I'm planning on servicing my Marzocchi 350 R myself and was wondering whether anyone here has hacked, bodged their own dust and oil seal presses.

 

At the moment I'm just going to do an inspection, oil change, grease and clean, so won't be changing the seals. Nevertheless, I'll need to do that in the next 6 months or so.

 

Has anyone here bought the seal presses or simply improvised a solution?

Just use a socket that is closest to what you need.Support is not really great on the Marzocchis

True, but the issue is the dust seals that you have to first put onto the stanchions prior to pressing them in. For that, there is a press that consist of two halves that you use to press the seal in whilst it already on the stanchion.

I put my dust seals (currently running enduro seals) in the fridge for about 30 minutes before fitment. Went in like a charm yesterday, no special tools needed to fit them.

For my oil seals, I use a nylon rod I machined to the OD of the oil seal. 

I usually wet the seal and seal bed with the suspension fluid using my finger prior to fitment, and had no issues thus far.

Sage advice.

 

I read a review on CRC's website where the guy meniotned that his Enduro seals were so stiff, that it actually started leaving rub marks on the stanchions. What's your experience with them?

 

I'll either go with the original Marzocchi seals or those green SKF ones.

Side note: According to Marzo's website, the correct oil for my fork is "Oil SAE 7,5 - Cod: 550013".

 

Can I use this: https://www.bike24.com/1.php?content=8;product=11470;menu=1000,185,190;page=2 in the SAE 7.5 W variety?

I only rebuilt the fork yesterday, have not used it yet, so can`t comment on the sanction wear yet. But I have a set of original Marz dust wipers I am thinking of fitting to reduce the chance of wear. I also read some reviews of the green SKF seals that also chow the sanctions. Guess only time will tell.

 

As a side note. I ordered normal off the shelf oil seals with the correct OD / ID/ Height  of ebay and Ali express for about R50 bucks a pop. Received one set Saturday, and very happy with the quality.

 

The original seals in my Marz was NGK, and out of my experience in the engineering world

SKF, NGK, etc quality is on par. Just make sure that everything is clean and dust free when you assemble.

 

On your question of the oil. I play around with my viscosity. I have SAE 5 and SAE10 in my garage, the local bike shops does not stock 7.5W for some reason. My current mix is about 2 parts 10W, 1 part 5W, and the rebound suites my needs perfectly (in my current 130mm Drop-Off) will check the mix in my 180 Bomber and let you know how it went.

On a side note...the mods I do probably verges on fringe science. Droo is the best guy to speak to for sound advise. I enjoy tinkering and doing mods to things.

I also open, clean and lube my forks regularly to check for wear etc, and so far had no issues on any of my forks

I have the Marzocchi tools and they are great.  I use them for Fox and Rockshox wipers as well.  My experience with Enduro wipers has been good to date.  To fit the oil seal you can use a piece of plastic wash basin waste pipe.

Good to hear.

 

Had a quick look around and it seems that the seal presses are becoming quite scarce. Will see where I can source it later this year.

Are the seal you are talking about the dust wipes?  and if so is the "tool" not just a piece of plastic that was cut to hug the dust wipe and then you just give the thing a light whack?

 

If not which seals are you talking about?

Some seals have the seal and wiper in one - like Fox and RS while Enduro and Marzocchi are a separate oil seal and dust wiper.  Marzocchi have two tools - a mandrel that you use to drive the oil seal into position with a mallet and the tool for the wiper (described above) that fits around the stanchion in two parts and then you press the wiper into the lower with the fork crown assembly.

Thank you !       I assume DVO and X-fusion then also have the two in one seal/dust wiper , just based of how they look...
