I think the OC-4s just run cool.  I can't get mine up to temperature on cold, winter days.  I had mine on fast idle for 45 minutes and could put my hand on the engine and it was just warm, the temperature outside was in the high teens.  I pulled the dipstick and touched the oil and it was just warm, parts of the radiator were a bit warmer, but not hot at all.  I didn't register anything on my temp guage.

Thanks, the instructions call for cement on the seal before pressing in.  What kind of cement would this be?  Also, I always use a thin coat of Permatex for the gaskets on cars...I assume this applies to crawlers as well.  Thanks for all your help.

Thanks guys.  Chris, you really know your stuff.  I was told that this machine was used to clear the city of Woonsocket, RI sidewalks of snow.  The arm that holds the muffler attaches to a bracket on the right side of the cowl that has been welded on.  There is one on the other side as well.  It looks like it could have been a part of a set up that enclosed the cab for those cold plow nights, but not sure.  Feel free to post it on your facebook.  Chris, I am sure I will be calling you for parts!

Hello,

I am new to crawlers and just went crazy and bought a mid year OC-4.  I know nothing about this, but it sure looks cool.  It is a gas 3 cylinder, has a model number of what looks like OC-4-42-86, can't read the serial number and has DAVCO badge on the nose.  It runs, doesn't smoke, needs a tune up, drives well (I think), and the water pump is leaking.

I plan to rebuild the water pump next week and can use any advice anyone has on the pump or anything I should check, watch out for.

Thanks for your help.
