I was asking a while ago about the info on a size of a perkins engine with very few people who could help I thought I would do some homework and here it is.
In the No of the Engine eg Perkins 4203 the first No is the cylinders. The last 3 No's are the Cubic Inch. So a 4203 is a 4 Cyl 203 cubic inch engine.
Engine Cubic Capacity
4108 / 1770cc
4154 / 2524cc
4165 / 2704cc
4182 / 2982cc
4192 / 3146cc
4203 / 3327cc
4215 / 3523cc
4230 / 3769cc
4236 / 3868cc
6 Cylinders
6247 / 4048cc
6354 / 5802cc
Hope this has been help to some of you.....
