I haven't seen so much rust in a block in a long time, but I'm going to make a new baffle plate for the water jacket.  I'm going home to check my parts manual tonight, but does anybody have a picture of a good baffle?

thanks - terry

yes, all but 3 of the water jacket cover bolts broke.  I am going to take pictures and post when I have the various castings in the various machines to work on.   this will be a story in progress!

As you may have found out already, in order to remove the crankshaft you will need to remove the rear main filler block. This is a die-cast piece and will likely  come out in pieces and you'll need to have a new one made. Hopefully someone out there can provide the dimensions or a replacement part.

As most probably know the Erskine for 1927-29 used a non-Studebaker engine. The 1928-29 models 51 and 52 utilized the model 9-F Continental which was a 160 c.i. Six (2 3/4 X 4 1/2') with 43 h.p. Top speed with the standard 4.78 gear was 62 m.p.h.

well, the engine overhaul over the winter turned into - I hope I have time this fall to work on my own engine for a change! - here's a few pics so far:

silver soldered crack on front of block,  got the water jacket bolt holes drilled and tapped,  and a pic of the lifters before and after resurfacing on both ends

(looking back on some of these pics I interesting, ive never taken time to do the before and after picture thing)

so here's a couple more:

lifter cam ends resurfaced

lifter valve end in valve grinder butt wheel (cam ends done in same wheel, but have to rotate lifter to get swirl pattern and convex shape)

turning valve heads to fit exhaust seats, then grind the faces in a valve grinder - early 2000s Chrysler 3.3l engine exhaust valves fit intake seats,  for the exhaust valve I turned heads to 1 11\32" to fit in exhaust seats

ill get more pics - vw diesel retainers, perkins 4.203 outer valve springs and Chrysler keepers to finish the valve train
