MADDOG93 Posted December 20, 2014 Share Posted December 20, 2014 What needs to be done for this switch. Every thing should line up right ? Quote Link to comment Share on other sites More sharing options...
Superdog Posted December 20, 2014 Share Posted December 20, 2014 you'll want to change transmissions and rear end,too,the trans. will be too light for the engine and rear end ratio will be too slow,going from gas to diesel.motor mounts will have to be changed too,most likely.

MADDOG93 Posted December 20, 2014 Author Share Posted December 20, 2014 Thanks Superdog, the donor truck has a 6 speed low hole that is going with the 237 as a complete unit into the B Quote Link to comment Share on other sites More sharing options...
Superdog Posted December 20, 2014 Share Posted December 20, 2014 A friend of mine up by Chicago did this to his B-85 ex-firetruck a few years ago,made a different truck out of it. Quote Link to comment Share on other sites More sharing options...
VALS327 Posted December 20, 2014 Share Posted December 20, 2014 Hello Angelo, you should not have any major issues. I have repowered 2 C model fire trucks with ENDTF 673's. I needed to swap out the front motor mount, have radiator top tube moved, and a few other modifications but nothing crazy. The C model gassers already were plumbed with a return fuel line and I'm sure your B is plumbed the same. When finished I replaced the carrier with one with a 4.25 ratio which gave it a nice speed range in the low 60 MPH range. Totally changed the truck. I have had nothing but trouble with the 707. After the repower I would take the trucks just about any where. Good luck with the repower and feel free to call me any time. Don Quote Link to comment Share on other sites More sharing options...

General Ike Posted December 20, 2014 Share Posted December 20, 2014 Angelo my B85 with the 6v53 (I know people it's a green leaker start the hating now) is a pleasure to drive. I've driven a gasser before and the difference is night and day. Can't imagine how nice a six speed would be.Is the 237 going in the old E-59?Sent from my iPhone using Tapatalk Quote Ed Smith1957 B85F 1242 "The General Ike" Link to comment Share on other sites More sharing options...
57 bcr Posted December 20, 2014 Share Posted December 20, 2014 I was told to put a 237 in a B,you had to retain your water pump & harmonic balancer from your/an END673/711. I have a 237/6 speed to install in the chassis I bought from Superdog. You can see it won't fit without doing the harmonic balancer/water pump swap. My 237 has a 3 fan belt set up,where the END673 has a 2 belt set up. My 2 cents.......Al Quote IF YOU BOUGHT IT, A TRUCK BROUGHT IT..AND WHEN YOU'RE DONE WITH IT, A TRUCK WILL HAUL IT AWAY!!!

General Ike Posted December 21, 2014 Share Posted December 21, 2014 Sorry I don't know why I thought it was E59. Good luck. Sent from my iPhone using Tapatalk Quote Ed Smith1957 B85F 1242 "The General Ike" Link to comment Share on other sites More sharing options...
Maddog13407 Posted December 24, 2014 Share Posted December 24, 2014 yup, front crank hub has to be changed, the gas job trans mounts are different than a diesel. you can probably re use the radiator with some fancy plumbing, I have used a B68/B62 radiator before in a B61. also need to put the 1/4 inch spacer plates between the front spring hangers and the radiator crossmember to move it forward or it is a real bitch to change a fan belt if you don't!
