notime1977 Posted September 29, 2005 Share Posted September 29, 2005 Will an ENDT 673 C fit in a B-model? I was looking at a 1968 R611 today, that had this engine a duplex and 4.25 ratio rear. The starter is in the same place as my B61 steering box. Any way to get around this? Thought I'd run the single axle R model with a 5yd dump box until I can get the B model further along(rewire, new airlines and paint/ body). Then change out the engines, as the R611 cab is rusty sagging and bent. Quote Link to comment https://www.bigmacktrucks.com/topic/403-endt-673-c-in-a-b61/ Share on other sites More sharing options...
John Woge Posted September 29, 2005 Share Posted September 29, 2005 Put the flywheel housing from your B on the R engine.....but check oil pan to see if the starter will fit. I learned the hard way that a b-model pan has a slight taper so there is starter clearence. you may be able to swap pans also ???

Andy Wright Posted November 2, 2005 Share Posted November 2, 2005 No TimeMy 1960 B61T has a ENDT 673C in it. Fit looks good. However, not having done the fitting myself (was how I bought her), John's comments were very interesting. Will have to have a good look and see what I can work out!CheersAndy Quote Whatever rubs your buddah.

pennsyjeff Posted November 28, 2005 Share Posted November 28, 2005 I am in the process of doing what you are asking right now.... I bought a '78 R model with a 673 with Jake, turbo, and aftercooler, (they tell me it is a 300 plus) and am installing it in my '64 B-61 tandem.... I know the front mount is different, the bellhousing bolt pattern is the same, but I have to go from the 3/8" bolts to 7/16" which I have taken care of. We can talk on the phone if you want. In a few more weeks, I will have more info......I think I can leave the starter on the driver side, from my measurements, it looks like there is room...If someone knows this is not correct, please let me know........Thanks.

b61fred Posted December 1, 2005 Share Posted December 1, 2005 Hi, I think the starter will clear the steering box. I pulled the engine out of a firetruck with a 707 gas and the starter was by the steering box. The 707 has the large bellhousing and basic deminsions of a 711 diesel, but the starter is on top instead of on the bottom. It was a very tight fit but the starter fit.

Superdog Posted December 2, 2005 Share Posted December 2, 2005 worst part about leaving the starter of the top left is that it makes it a bitch to change if it ever goes bad.

b61fred Posted December 2, 2005 Share Posted December 2, 2005 Thats right! It took longer to get that starter off than pulling the rest of the engine. and thats no joke.Fred Quote 15 gears...no waiting!

b61pickup Posted January 18, 2006 Share Posted January 18, 2006 Hi, I have a b61 with a 673 and the starter is on the driver side from the factory. I am in the process of installing a 676 285 and 5 speed in mine and although I have not got that far as yet by the measurements I have taken it should all fit with no major probelms. I know the blocks are all the basic same size. Quote Link to comment https://www.bigmacktrucks.com/topic/403-endt-673-c-in-a-b61/#findComment-3456 Share on other sites More sharing options...
