Yes, the 9600H used a GMC 248. The smaller GMC trucks in Canada used a 224 inline six. The 224 was a 216 bored 1/16” to give the larger displacement so the GMC would have a different engine than the equivalent Chevrolet.

The PO of my C15a had a rebuilt 224 that bolted right up to the CMP bell housing.

So Paul in your GMC manuals any pictures of the double action shock absorbers as seen on CMP????

Hi Bob, my manual doesn’t have pictures of the shock absorbers on the vehicle but does have a section on overhauling the double acting shocks.

I have never been able to take one apart with out destroying it. Heat to loosen up the lever usually kills the oil seal at the very least.

Mind you over the years, I have found that if they move and are refilled wiht oil they are good enough for a CMP...... drove mine for a while across the backfield without them and noticed no difference when I installed them.

do you have any tricks to dismantle a totally salt pickled shock absorber?Some guy (Hemmings) in the US rebuilds them with a $150 core charge + time + parts.

Hi Bob, there may be some confusion about Canadian GMC engines. The U.S. GMC trucks used the 228, 248, 270 series GMC built engines. The Canadian trucks used a bored out 216 that displaced 224 cubic inches, only the heavy duty trucks used the GMC engines.
