Can you fella's help me with what is correct, what is aftermarket, and what is missing? I know the crankcase breather is missing, and the air cleaner. What else might be missing? I have figured out the vacuum pump on the right side, and the fuel pump. The canister that I see on some earlier models on the drivers side, beside the carb, left side isnt there? Any help, or identification of parts is very helpful. I have figured out that the firing order is correct, and that there is a solenoid on the starter, so no foot stomp.ANy other info will be much appreciated. right side | | | | | Joined: Jun 2006 Posts: 693 'Bolter | | 'Bolter Joined: Jun 2006 Posts: 693 | the canister on the left side is an optional oil filter, so it isn't surprising that that isn;t necessarily there. your heater hose ports are plugged, so your heater is not hooked up and may be missing.
also looks like someone put an alternator in there for battery charging, rather than a generator. | | | | | Joined: Apr 2012 Posts: 37 New Guy | | New Guy Joined: Apr 2012 Posts: 37 | It is looking less and less original all the time. So the story goes I guess. It will be interesting to post the rest of the pics later in the week and get the input on the rest of it. Thanks.

How could you tell from the motor pics? You have me stumped on that one.

All Hydramatic equipped trucks use a solenoid type starter, rather than a "stomp" starter. That got my suspicions up. Then I looked at the throttle linkage and that pretty much confirmed it. | | |
