Block replacement

[Tim Op't Holt]

On my H31 the block that the jib sheet runs through at the stern, has a deteriorated sheve and must be replaced. It has a Lewmar sticker on it, but I don't see it in the Lewmar website. Has anyone else replaced this item?

Did this two years ago...

..and they were not listed on the Website then either. Send Lewmar an Email and ask them about foot blocks. I got he correct blocks by giving them the distances between the mounting screw holes. Unfortunately the axel that the sheeve turns on is pressed in and peened over so a DIY just can't cheeply replace the sheeves. Bill EblingYesterday's Dream1985 H31Crab Alley BayKent Island, MD

Contact Garhauer.

Tim:Contact Garhauer and see if they will custom drill one of theirs to your measurements. They have good prices and good quality. They are located in Southern California.

I did it myself

I turned the block over and ground off the peened over part with a dremel. Then I purchased a new sheeve and reinstalled the pin from the back side. It will stick through to be just flush with the outside face of the block and will be held in by the deck surface it is resting on. Kind of crude but is has worked now for 3 years.

Bret..I should have tried that..

I can't remember.. When the foot block is seated is there a recess under the block that would allow enough room between the pin and the boats' glass to slip in a piece of aluminium sheet in to protect the glass from getting punched by pin? Alternatively aluminium is so easy to work with with DIY tools you could make a full 1/16" aluminium "gasket" plate that the block could set on and the whole thing seated with cauking, sandwiching the plate between the block and the glass. The pin couldn't slip then

I seem to remember

there is a recessed area about 3/4 diam. where the pin comes thru. You could put a quarter or nickle sized piece of metal there, but the head of the pin which used to be on the top will take up that space so you would have to do as you noted and place a backer behind the whole block. I did not do so, but I doubt the head of the pin which was around 3/8 inch would push thru, but I could be underestimating the forces created with extended use. Any way the pin head ends up flush with the back and therefore the deck surface holds it in. Has worked for me for 2 years of weekend sailing.
