Update on this thread:
When we were in the yard in San Diego
, I was referred to a diesel mechanic
(Vince Balch) who estimated $5000 for a new transmission
plys labor, and sold
me a "sweet little Volvo" he had in his shop, a 2003T. It failed by Ensenada; I went on craigslist and found a tired 2003 (30hp) to drop in. Nothing but trouble since.
in La Paz
later informed me that while he hated Volvo's for their parts cost, the ZF/Hurth transmissions used by Pisces were notoriously weak and troublesome, and now that I am preparing to install a Perkins
4-108 he suggests I use the transmission from my Volvo
. He prefers their 'cone' clutch
mechanism, and the overall quality.
The other issue is that my problems started when previous owner replaced the 7-degree angled transmission with a straight (off-center) unit, and failed to mount it correctly; the Volvo
also required some cutting/shaping of the mounting frames to make it work
. Apparently down-angle transmissions are rare, and most installations accept an amount of tilt; this seems wrong, in terms of oil
starvation in large seas. I guess you just keep it topped off.
