Well to start off I'll give a bit of history--my Jabsco water
pump on my old Perkins 4.108
was pissing water out the back. On removal
I noticed that everything needed replacing-wear plate, front cover, cam, seals
, impeller etc etc.--Having some unspent Xmas $'s left over in my credit card caused me to splurge and buy a whole new pump (hoping to rebuild
the old one over a period of time). NZ$500 later my beautiful new pump arrived (they REALLY are brass--hard to tell looking at the old one
). I decided to go the whole hog and replaced the hoses and hoseclamps as well (big spender).--THE PUMP RAN FOR ALMOST EXACTLY GIVE OR TAKE APPROXIMATELY 1 HOUR. Then my temperature gauge went crazy and zero water came out the back of the boat.
of MY BRAND FRIGGIN NEW PUMP - I noticed the glaring anomaly of the spline, seemingly cold pressed onto the shaft, spinning in a totally useless manner and therefore producing no impetus to the impeller, ergo--overheating engine
. --this reminded me of the following little missive that came contained in the pumps box (follows later in RED
). I thought this was of no consequence to me , AS I HAD NOT LOOSENED THE ADAPTER PLATE AT ALL, BUT HAD GONE TO GREAT TROUBLE AND LOST
A SIGNIFICANT AMOUNT OF SWEAT,KNUCKLESKIN--AND PERFECTED THE ART OF CONTORTIONISM TO REMOVE MY PUMP WITHOUT LOOSENING THE FRIGGIN ADAPTER PLATE...
Unbeknown to me, my intelligent(NOT!!!) diesel mechanic
person who had refitted (at great cost) my injector pump
, had deemed it necessary to loosen the flippin adapter plate------ HENCE THE FOLLOWING BECOMES NECESARRY
NOTICE: If installing this pump on a Perkins 4-107 or
4-108 engine, it is essential that the pump shaft is
properly aligned with the driving-shaft on the engine. If
the pump adaptor plate (Perkins Part No. 33154119) that
the pump mounts to has been loosened, it must be
realigned using a special Perkins alignment tool when it
is resecured to the engine. Contact your Perkins
Service Dealer to arrange the adaptor plate realignment.
Failure to have the adaptor plate properly aligned prior
to installing the pump can cause severe damage to the
pump and/or the engine.
To cut to the chase--does anybody know how to perform this alignment WITHOUT contacting my nonexistent knowledgeable friendly Perkins Service
