The engine is stuck... I have a new set of pistons and new valves ...
These motors have poured big end bearings with shim adjustment , similar to chev 216 . Mains are conventional type shells .
The truck is over engineered in some respects eg.. rear axle is more like a 4 ton truck setup, steering components also very strong, probably as RF tyres were standard fitting .

Hi Mike,

A look through the Chilwell Census list, for your Contract number comes up with this;

Z4434248 to 4434607 Cont. No. V4152 Cat. Ref. 209
Truck, 15 cwt, 4x2, Chemical, type CS8 Mk.III, June 1941

( the date may have been gleaned from a spare parts list as the list is a repro with added information. )

regards, Richard

Thanks Richard

Interesting ... that contract includes some GS and house type wireless vehicles also ... God only knows what this one was . Sadly, I don't have the Z number as the bonnet is missing ... it doesn't appear to have had the towing setup on it . The only clue as to its previous use is: On the grill , is hand painted "Q 5 " in large size script .

The bonnet from the 1939 CS8 wreck ...this bonnet is from a later truck I think... number is too late for 39

Spent a few hours tweaking the spanners and the motor is ready to come out

Good news: No rust disasters in the cylinders , about 5 thou ridge evident .

These motors have some oddities:

All threads and bolts are metric . Morris bought the French Hotchkiss factory and inherited the Metric tooling .

Valve lifters are located in three seperate blocks that unbolt from main engine block

bore is standard 82mm ... PHEW

Slight disaster .. tried to remove one of the water jacket side cover bolts.. one broke like it was made from putty .

Carby is a replacement .. A Carter BB-1 .. a generic aftermarket carby used on many cars

Hi Mike,

Yes, that contract was for several different body types, but the Cat. Ref. No. on the Contract plate narrows it down from what I found in the Chilwell list, 209 is the Truck, Chemical. Now this type of vehicle has come up before, seem to think it might have been something to do with washing down in the event of chemical weapons being used, could be a bit wrong there, but sure someone will know.
