Super 90 engine swap

ptfarmer · Jan 3, 2018

Will a Perkins 4.236, 4.248, or 4.318 bolt up in a Super 90 (I heard the 4.318 will).

A4.318, yes. Will bolt right in but may need front oil pan horizontal hardware changed to studs/nuts, depends what pan is used. 236-248 will not fit as rear flange is nothing like the A4.300 and 318.

Rear flange on the crankshaft, or?

Super 90 engines bolt directly to the bell housing, no adapter plate.

Rear block flange of the 300/318 is different from the 236/248 bolt pattern. Super 90 and 285-1085 transmissions clutch housing have two 5/8 NC bolts in the bottom, other smaller MF transmissions never used them.

No adapter plate on 236/248 blocks either. Adapter plates were used on Perkins 152 three cylinder, 192, 203 four cylinder, 305, 354, and 372 six cylinder blocks used in MF applications.

(quoted from post at 18:00:13 01/03/18) Rear block flange of the 300/318 is different from the 236/248 bolt pattern. Super 90 and 285-1085 transmissions clutch housing have two 5/8 NC bolts in the bottom, other smaller MF transmissions never used them.

Is the 236/248 bolt pattern exactly the same other than not having the two 5/8 NC bolts in the bottom.

None are the same. 85-88-S90 use a slightly larger "bell" housing.

A Super 90 is a hulk compared to a 175/180.
