Steve, is your engine a 3 cylinder? I saw two of them seize in small rollers. The engines where Perkins, assembled in UK with parts from India. If yours is similar, has the injector pump cast into the cyl block, governor and oil pump in the front cover. Look for this when you take it apart. The one I had apart had a rotary oil pump mounted inside of one of the timing gears. The gear used a bore in the front cover as a bearing. The rotary pump was driven by three small pins, the pin holes were drilled in a groove around the bearing surface of the gear(midway along it). Look for a groove gouged in the bore of the front housing by the drive pins. There is a spiral spring wrapped around the gear and should be in the groove holding the pins in place. The one I had, the spring was pushed back against the gear teeth and not in the groove. The drive pins had nothing hard to hold them in place, they just ran against the housing bore and soon gouged out the aluminium untill they no longer could drive the pump. Then no oil pressure and seized crank.

I think that knowing which engine, exactly, that Steve has would be very beneficial. This info, along with others' first hand experiences, will help the reader determine if this particular engine may be troublesome, or if Steve's is a somewhat islolated case. I, and I'm sure Steve, would also like to know if he has any, possibly more reliable, options for replacement. Steve has given the ID badge info. Can't anybody tell us eactly what engine he's dealing with?
The one I worked on was cast of grey iron, very crumbley, not the good cast you would expect in a Perkins.Just looked at the I.D. Info, it is a Cat-badged Perkins 700 series, 3.0 litre displacement. Sounds like it's suffering from a porous block. Ps, this didn't come from a library, either.
The break is clean, the edges of the break are not polished like they had been rubbing against each other.
