Guys.

I have a lead on a 4 cylinder Perkins diesel motor that come out of a sail boat, i am trying to build a generator for the farm and i want a diesel motor drive. does anyone know the history or reputation on a Perkins 4 cylinder Model 4107or 4108 motor.

Thanks in advance..

Anthony..... :)

These engines were what easystart was invented for   :D

Fred Bloggs:
I agree with John S. on the easystart, I had one of these engines (4108) fitted (factory) into a 69 Ford Transit Van. It ran well but was a barstoll to start, I put a heavy duty battery on it and uprated the cables from the battery to the starter to 65mm CSA welding cable and put 2 or 3 extra earths using the same welding cable onto the chassis and fitted and extra glow plug starter into the air intake to so she would swing over fast enough in winter (UK only) to start. Sometimes on really cold morning I would have to take off the air filter (oil bath type) and stuff a piece of lighted news paper into the inlet manifold and quickly spin her over to get her to start.
The other major gripe is that they only have a 3000 mile service interval as the oil gets a lot of carbon etc in it.

Otherwise a good engine, my van had done about 400,000 miles when it was stolen in 1992 from a carpark in Cannock, the police said the engine was probably in a canal boat within 24hours :bang:

It also was very good on the fuel, at a steady 40  to 50  miles an hour she was doing 35-40 mpg.

Best regards

Fred

Ummm……. At the moment its sounds a little disappointing having to shove a copy of the Financial Times and catch it a blaze in the air flow just to get it started.  :bugeye:

I wonder if this unit I am interested in comes with a box of matches.  :coffee:

What other use would an engineer have for the Financial Times except propagating combustion or emergency toilet paper  :lol:

The earlier Perkins engine numbers indicate the number of cylinders and cubic capacity in inches so a 4.108 = 4 cylinder 108 cu inch engine.

Despite the similarity of type numbers 4.107 and 4.108 were very different designs.
The 4.107 used wet sleeves or liners in a skeleton type  cylinder block,whereas the 4.108 employed a more conventional one piece cast jacketed cylinder block.

Both these engines were of the high speed indirect injection design and it was this that made them a difficult sod to start in cold conditions and sometimes even warm conditions.

Also as a previous post has said they required frequent oil and filter changes or engine service life became greatly reduced.

The far more desirable and reliable workhorses in the Perkins stable were the direct injection engines
 such as the 3.152, 4.236, 4.248, and the 6.354 all of which were fitted to various Massey Ferguson tractors, combine harvesters and many other manufacturers industrial vehicles and plant and offered as normally aspirated or turbo charged depending on output requirement.

The bottom line is if I were looking to source an engine for a small generator plant I wouldn't bother with a 4.107 or 4.108.

If a serviceable 3.152 or 4.236 was available I'd be tempted but these days there are plenty of super reliable car diesel engine units available from the breakers yard such as the Peugeot 1.9 or 2.0 litre units,which incidentally, Perkins have had a role in at the consultancy and design stages.
