Topic: Helm pump broken. What is it ???

Author Message Prev Topic | Next Topic  PanchoCC "Seaman Recruit" Joined: August 18 2008 Posts: 15 Posted: November 25 2008 at 19:26 | IP Logged Helm pump is broken/cracked at shaft for steering wheel. When I press on the crack it weeps oil. I have linked photos of the steering. Hydraulic cylinder/jack at tie rod has Syllen label. Helm pump beneath steering wheel has Syllen/Teleflex label. It does NOT have a removable collar cover with three Philips head screws, which is a characteristic of all Seastars.  So what is it ? I can not determine the model of this helm pump. If you can help me do that, then I can try to find another housing, seals, etc. to repair this one. Maybe I can find a used one and put a new seal kit in it. I don't know. But I would like to avoid springing for the big bucks if instead I can find a way to repair this one. If someone can help me ID this thing, then maybe I've got a fighting chance. Have been all over the marine site.  No info. Here's a link to photos: http://www.panchogun.com/FVWebPhotos/FV-Boat-Steering.jpg Edited by PanchoCC on November 26 2008 at 00:18 __________________ Chriscraft 337 Commander (1985), twin 454 Mercs w/quadrajets, IB drives, Onan 6.5 Genset.

Here it is (I paraphrase). Helm company was Syten, then Syten/Teleflex, other variations, now Teleflex. Syten made a helm pump up to 1984, labeled Syten/Teleflex (mine). My boat was made in 1985, and 86, only. When Murray Chris Craft took over in the early 80's they added the 337 (aft cabin.), only built the 337 for two model years (1985-86.). No too many of these built--a Genth hull, the 333 series, which later became the Amerosports and disappeared from the lineup in late 80's.Apparently, Chris Craft used some 1984 vitage Syten helms in their 1985 boats. Teleflex says no parts available for these, at all. In 1985 they came out with the Seastar series with a field replaceable front shaft seal (tools: safety pin and philips head, seal 2.97). Teleflex sent me a list of parts necessary to replace my broken relic, with a new Seastar HH5271, Helm pump. Here is list: * HH5271, Helm pump, 1 ea (one per steering station) * HA5418, Adapter plate, 1 ea (one per steering station) * HT5100, nylon tubing, 1 ea (100' cut to fit tube. ONLY REQUIRED IF YOUR CURRENT TUBING IS THE ORIGINAL TUBING FROM THE DAY ONE) * HF5520, Cylinder bleed fitting kit, 1 ea Such is life. __________________ Chriscraft 337 Commander (1985), twin 454 Mercs w/quadrajets, IB drives, Onan 6.5 Genset.
