Title: injector pump ... mechanical or hydraulic?
Post by: Rudderly Confused on May 26, 2018, 12:51:32 PM
Stupid question of the day ... how do I tell if my injector pump is mechanical or hydraulic?  I have a Westerbeke 40 in my 1978 365 ketch, and probably need to replace the #1 injector line, which is part #46 on the parts diagram.  But the parts description lists 4 different options for #46, based on engine and if the injector pump is hydraulic or mechanical.  I'm thinking I need #46-4, which is described as "mech pump 107-108-ED", but these lines aren't cheap, and I don't want to order the wrong part.
Secondary stupid question of the day, since the W40 is a Perkins4-108, is it cheaper to get the injector line from a Perkins dealer than a Westerbeke dealer?

It has been a very long time since I sent a question or responded to a posting. I believe there was a movie years ago that had the line.......I'M BACK!!!!!!!!!!
Any way to your question. You should absolutely check pricing from other sources.
Case in point. Years ago ( More than 15) I needed to replace the raw water pump on my westerbeke. Hanson Marine quoted me either $300 or $600. They asked if I wanted it with or with out the pressed on pulley. That  was $100 extra as I remember.

A member of this wonderful site said " It is a Perkins  107". I had no idea what that meant!!!

Well I learned. I contacted a Perkins dealer servicing the farming Industry in upstate New York. The counter guy was beyond helpful. He said I could have it with or without the pulley.  With was $5.00 less with pulley without it was $110.00. Guess which one I ordered.
There was a difference however the Westerbeke was red, the Perkins was black.
By the way, it's still black.

Good luck

Henri

I found it was far cheaper and easier to go to a good injection shop and have one custom made for me.
