Mid Winter Workshop

Busy through the winter, here are some snapshots, more to follow:

Triumph Dolomite.











Chevrolet Truck:
Window wind mechanism and Waxoyl the inner doorskin.







 Wolseley Hornet, final engine modifications and details including a modification to chain guide in Tufnol material; some further attention to the beginning of a crack in the cast iron drive housing for the water pump and oil pump skew drive assembly. This demonstrates Eutectic Metalspray equipment designed for this type of work. It allows small precision deposits of material to the damage area at a relatively low temperature for a "hot" repair. The crack is then reinforced internally with a bronze sleeve machined and lightly pressed with Loctite.













Breather oil catch tank located beneath the supercharger on the side of the engine.


Final setting up work with very careful spline dressing, engineer's blue and end float adjustment.

Below picture shows the modified Tufnol chain guide, hidden and camouflaged to the right of the picture with the chain against it.


The water pump drive shaft had the end section removed for some reason? We have set and machined a suitable slot to accept a steel "tongue" to be silver soldered into position and provide the water pump drive.

' 56 Chevrolet 3600 235

We have this lovely Chevrolet in the workshop for a few jobs including looking at oil leaks around the rear of the engine as well an issue with the passenger side window winder.






Below, the rear main bearing cap has been dropped to consider rear main seal condition, at the same time we can renew the gaskets. The rear main bearing journal and shell are visually in very good condition.
Interestingly the flywheel is very clean suggesting the rear main seal is in good condition, it may be prudent to leave the top seal untouched and pack a new section into the cap portion. It appears that most of the oil has been leaking from the rear of the sump gasket.


We have lightly oil stoned the cap faces to check for bruising before preparing for assembly.




We are hoping to see if we can recover or repair the window wind mechanism on the passenger side. Despite making a suitable "clutch head bolt" tool (Chevrolet fittings from this period)  from an HT bolt (above), there is "always one" fitting that fights. This one bolt had already given someone a hard time before as it has quite a lot of damage.
