Stripped the forks on the V7 Special today to fit new springs. The existing ones may soon be celebrating their fiftieth birthday.What I was unaware of was that both fork seals were leaking, who knows how old they are? The seals are housed in a chrome-plated housing that screws onto the slider,much the same as a BSA, Triumph etc. I have the tools for the removal of the aforementioned makes of seal holder but not for Guzzi.So how to remove them? Some folks have managed with a strap wrench and liberal use of a heat gun. I tried that, to no avail. The Bsa tool looked as if it might do the job, no about half an inch too short.The pre unit Triumph was much too short. I could buy one from the USA but the carriage and duty made it much too expensive. Stein Dinse has them so I've had to cough up sixty euros plus postage to un-fasten two threaded sleeves.

Too late now,  but for the Bantam I bought a bottled gas spanner, 27mm one end 30mm the other (as it turns out), it's a thin spanner like flat steel plate so at the 27mm end I folded the tips over to 90° and ground them down a bit to make sharp right-angled tangs, this "peg spanner" works on the Bantam seal holders perfectly, altho fortunately they weren't at all tight to begin with! (Came off with big pipe pliers) but I could make them tighter than that going back on.

A gas bottle spanner wouldn't have done it Mike.This is the required tool.

Hi Dave I have a tool which I got from Harper’s a similar price that you have seen I think, the trouble I had was that the lugs rounded off as soon as I put any pressure on it. Heat and a lot of it I think is the only way mind I’ve only done two sets of forks myself.  I put up a post on here a while ago when I did my first set. I posted a picture of my rather unprofessional setup however it did work. The date of the post was 21 March 2017 if you search under Loopian you should find it.  I’d be more than happy to lend you my shroud removal tool but it is a bit mashed up and I think If I was doing it again I’d probably try and make one out of a suitable sized socket.  If you want the dimensions I could try and give you some measurements. 
Good luck

I am the one mentioned on Greg Bender's site. I clamped the bottom of the forks in my big vice and used a strap wrench. If it slips put some tape round before the wrench. I used no heat. I am in the process of reassembling one of my forks on my Ambassador using the same technique. It has worked for me so far.

Assembling the fork is a pain too, but I made a Heath Robinson tool for this as well.

Thanks, chaps for the offers of help, it is very generous and proves what a fine lot of Guzzi types we have on this fine forum.
I have ordered the tool having found that Stein Dinse stocks it. I hope it's up to the job.
I have no trouble re-assembling the forks which I did when I replaced the springs on the 850GT using my Brit Bike fork puller.I had a Guzzi size threaded plug made to add to the collection.


I'll let you know how I get on. Thanks again. https://sjmotorcycleengineering.com/products/bsa-norton-triumph-matchless-ajs-etc-fork-assembly-tool-imperial-61-3824-sj565

Loopian, I looked for your post from March 2017 but the search facility will only allow me back to April 2017.I would have thought one could go back further than that but it would appear not.Unless of course I'm doing something wrong, which is not beyond the bounds of possibility.

Did you have "any date" selected? Wasn't aware that would restrict to 3 years.

I did the search under my user name yesterday and it came up with all my posts and I just scrolled through them. I’m not a prolific poster so it didn’t take long😀

I've just tried again but this time I could only get as far back as July 2017. Page seven of your posts Ian. Brian, yes I have "any date" selected.

Back to the forks. I spent all afternoon today trying, and eventually succeeding in repairing a CEV handlebar switch.I was just locking up the shed when my fork tool arrived from Stein Dinse. So I had to have a go of course. I was fully expecting the oil seal holders to be completely seized and the tool to be inadequate. However....The first attempt was not looking very promising so I added some heat from the heat gun and lo, on the second attempt, the oil seal holder came undone. The second one required more heat and extensions to the handles. I was waiting for something to give, the castellations or handles on the tool or some part of my anatomy.Anyway,the oil seal holder gave way first, unscrewing from the fork slider to my great satisfaction.
Expensive though it was it is nice to have the correct tool for the job.

Good to read that you've succeeded there Dave. 

One of the first things we learn when we're fiddling about with old vehicles, is that having the proper tool makes a big difference. You only need to but them once, they speed the job up, and reduce the risk of damage to expensive or hard to replace components.

You'll be on the downhill part of the job now?

Some cleaning to do tomorrow Pete. The stanchions appear to be in good condition as do the bushes; there is no apparent clearance excess between one and the other. Fitting the seals should be straight forward enough, these forks are very much like British forks of the fifties and sixties, as in there is very little inside them. I think rebound damping is mainly achived my the considerable mass of the rest of the bike above the springs and is not due to the sophisticated fork design.
