Work continues assembling the engine.
You can see below that this side of the case is now finished. The con-rods are sticking out ready for the pistons / barrels to be attached.
Below you can see the correct 25hp oil pump fitted. You can use any pre 1967 oil pump on these engines, but the correct one has a thinner plate as the edges / sides are more curvy
Now you can see below the correct domed-top oil cooler and the barrels fitted
You can again use a standard single-port oil cooler, but we had a few original 25hp domed top ones lying about so we used the correct one. Again with barrels & pistons, we can sometimes supply sets of 25hp ones, but readily available are 30hp ones.
Engine studs are all now in place ready to accept the cylinder heads.
Work now starts on lapping in the engine valves. Note here the difference between these two exhaust valves. The one on the left has a cut-in mark around it. We can supply valves for all years and sizes of engine.
Here we are setting the end float, we carefully measure this as its essential to set this correctly. We offer a handy little tool for doing this yourself. Click here.
The crankshaft main oil seal is now fitted
Next the flywheel and gland nut go on
The fuel pump is now in place and the dip stick fitted with the blob of red paint to high-light a service point.
