maybe contact the maker of your boat or maybe all boat business

Try this mob http://www.transeals.com.au/welcome/index.html

They have always been able to match up any seal or o ring I have needed

this is what i am looking for, cheapest is $135 but from the US, if i can i would like to try and support one of our site sponsors except no one has them listed anywhere. Seem like they are pretty hard to find in AUS
ill give it a week then to the US I go i suppose

a friend of mine just got one thru hayway marine they are distributed locally by bla part number 293714 a bit dearer to get in australia rrp $217 but they do give disc if you ask nicely and you dont need to worry about getting ripped off by someone from the otherside of the world

If you can get the top off take the seals into Coventry's or any other seal/bearing shop up there and they will be able to find a match for them at a fraction of the price.

The spanner thingy looks like one for your disc grinder, may have to make one up to suit the unit.

Try CBC bearings for the seals brad.

cheers yep

the spanner is the same as a grinder (pin spanner) just a different size to any grinder i have or have seen(typical), that is the cheap bit anyway can get one for $5US
dont have a lathe which i would need to turn up a tapered fitting to get the seal over the threaded section of the cylinder

will probably order fromt the US got a mate who has ordered from the same shop and had no dramas. I think once i have the seal in my hand i will take it to the seal shop to get a few spares, that way i have all the tooling i need for any next times.

still a lot cheaper than AUS or replacing the whole cylinder should be able to do it for $130, next time probably only about $25

i disagree totally with you till i would never set foot back in challenge marine again burnt too many times hayway are much superior for expertise service and most of all price you just have to know how to deal with people

whats the cost of replacement of the cylinder?

I replaced mine about 12 months ago, was only about $300 for it.

$300 for a HC5345? where is that?

anyway 300 bucks v's 130 which will make mine as good as new, its a no brainer

ordered today will be here in 5 days

i know i should try by aus but 217 plus postage v's 124 delivered to my door, looks like my dollars go to propping up the US economy. Even so, the local distributer purchases it from the US anyway, just with his bit on top.

Well it only took two weeks to get the parts here from the US and I am as of this afternoon back in business

one functioning hydraulic steering unit again, woo hoo!

 Does anyone know if the seal kit is better than original because after only one season the ram is leaking badly from both sides. If not then I might change brands.

It will depend on how much wear is on the actual shaft. If the shaft is worn and not just the seals then a seal kit is not going to fix the issue.

 As said above, if the ram is scored or marked it will cut out the seals.  Most important thing is to wash them down after each use, clear off any salt and then dry it out. If left wet dust and crap can adhere to the ram and cut the seals the next time the ram moves.  

At nearly $300 for a seastar seal kit and approximately  $450-500 for a seastar ram or $600 for a hydrive ram you have to wonder if the seal kit is worth it.
