cf685f Posted May 21, 2009 Share Posted May 21, 2009 Guys I am brand new to the forum, but wanted to get my first post out there. My Fire department has a L85 with a blown up 707A. I found another complete motor up in Baltimore County, MD. I now have it in the shop and have been working with Tracey @ Watt's to get parts. I cant find the serial # anywhere? Where do I look.I found the ENF707A number behind the oil fill cap; I found the block casting #s; there are stamped #s a each spark plug and three stamped #s on the side of the block behind the distributors. Tracey said the #s should be like GB11, but none of the numbers match.Thanks for your help. Tim707A707A707A707A707A Quote Link to comment Share on other sites More sharing options...
cf685f Posted May 27, 2009 Author Share Posted May 27, 2009 Well I just got back from the local Mack dealer and as I suspected there is no hand stamped serial # on the block. They were not sure what to tell me as the block many years ago was sand blasted and this must have removed the numbers. I have it down to a 707A, but Watts is telling me there were 6 different rebuild kits for a 707A because of bearing and crank sizes. Anyone know how I can easily tell the difference, so I can get a rebuild kit on order from Tracey? Quote Link to comment Share on other sites More sharing options...
