Replacing pulleys in gooseneck fitting on Dehler 36 CWS

[Dessa75]

Hi - I am about to replace the reefing line pulleys which are mounted on an "axle" or pin running set into the gooseneck fitting (this arrangement is probably common and not sued only on Dehler 36s). The axle/pin runs transversely through the cast gooseneck and appears to have some sort of inserts at each end of the hole to presumably prevent the axle from dropping out. Has anyone had experience with removing this axle/pin? Rather than attacking it with a large hammer and punch, I'm interested to understand what these inserts are made of - how do you remove them - does the axle/pin then come out without a fight?

Thank you

I'm not familiar with the arrangement of the pulleys in the boom of your model of boat, but some years ago I had to replace the outhaul/reffing line pulleys in the aft ends of some booms belonging to some Glenans 5.70s. AFAIR they were of Z-Spars brand and the "axle" on which they were mounted could be easily pulled out, using a needle-nose pliers , aft, from the aft end of the boom. In normal use they were held in compresion by the tension of the outhaul and reefing lines. It might be worthwhile investigating if yours would pull out forward in a similar manner.

Do you have a Selden or a Sparcraft rig?

Hi - I'm not sure what kind of rig we have but have attempted to attach a photo of the gooseneck fitting which shows the bottom 3 pulleys which are supported by the axle/pin which is embedded transversely through the gooseneck.

Dehler made thier own spars for these boats.

Haven't removed mine, (dehler 34) but the whole assembly was quite easily removed from the boom via the three bolts holding it in (side and bottom) might be easier to attack things from that position.

How old a Dehler are we talking about?

The boat is 34 years old and as jwfrary has indicated, the mast is a Dehler item.
BTW jwfrary - I have tried your suggestion but as is the case with boats, one of the 3 bolts is corroded in and I am fearful of breaking something. I have finally managed to attach a photo after dramatically reducing size.

In the scheme of things, my enquiry is a littly and I haven't even attempted removal yet - it may not put up the resistance I'm anticipating.

That is the same as mine.

The pin in yours looks to be essentially rivited in place, each end is spleyed out, the only way to get it out is to drill the ends. You could probobly replace it with a bolt of the right dementions or some plain bar and secure in the same way.

The bolts as you quite rightly say are easily broken, on mine all three snapped off, I drilled out and helicoil repaired them and then did the other end of the boom as well. Worth dealing with in case you break a reefing pennant.

I also added tuffnol washers above and below the gooseneck fitting to reduce wear a bit.

The pic isn't terribly clear but it looks like your axle is a tube that has been flared or swaged outward at the ends; if so it will need to be driven out with force or one end drilled away and the rest then driven out.

Yes. I'd say it is a tube flared at the end as well. Drill one end with a bit the same diameter as the OD of the tube and drive out.
Replace with a stainless rod either threaded at both ends and fixed with Nyloc nuts or drill a small hole through each end and secure with split pins, use stainless washers to prevent the split pins abrading the aluminium.
