Just registered There seems to be very helpful and knowledgable folks here Just purchased a 75B Need help can t find S# on frame does anyone know where? From looking at photos seems like early 70's with Cummins can't find those #s either Will DOT 3 Brake fluid work and be the correct fluid to use? Any help would be appreciated !
SN usually stamped on the rear hinge plate and inside the front frame. Cummins engine CT 464C machine S/N 428A-101 through 265 V504 443A 101 and after. 504 with modulated transmission (Soft shift) with auxiliary charge pump 443E-101-CB and after. CB means built in Ashville NC, CAC would be built in Canada. S/N usually on data plate in the cab somewhere.
Hi, oldseabee, thanks for the quick response ! I have read your answers in pass posts it was people like you I was speaking about. When you say hinge plate do you mean horizontal steel where pivot pins go thru to let the machin articulate? If so , so far can t see them, perhaps too much paint or not clean enough. There is no data plates on machine. I have other Michigan loaders but can t remember what brake fulid to use (our shop man passed away last year.) I thought is was regular DOT 1, 2, or 3. We did have one machine That did use hydrolic oil but again don t remember maybe Hough . I ll try to post a photo or two to see if someone Can peg year ( think '73) I also have another 75 and a old 275 that's been sitting . I d be willing to sell can t bring my self to send to scrap metal man that's about 59 or '60 with new Cummins motor.
Not that it will help with you Michigan, but all the Houghs we had used DOT 3. H90s, H100s, H120s. Just drawing a blank on the H400 brake systems???? Is there any fluid left in the system? Brake fluid has a different feel when rubbed between fingers, not a slick as a 10W Hydraulic would feel. Also try mixing what comes out with water. Brake fluid will mix with water and stay mixed, oil will just float on top.
I might be interested in the 275 is it a 275b? What's wrong with it why is it sitting?
Just rebuilt my entire brake system on my 55b and I used dot 3 no problems yet....
It' pretty old can t answer that. Suicide doors around 1960 When I bought it it came with a new cummins motor. I didn t use it much started it regularly. Then batteries when dead And leaked out some fluids over several years. It s been seating and didn t have time to deal with it. I believe in order to fit it into the machine the oil pan was cut down and may have developed a small leak . I didn t want to fill it up with fluids not use it and have it leak again. Should start haven t tried. It is a beast prob worth $5000 in steel. The motor must be useful to someone as well
Thank you guys for the other replies
Use DOT 3 in that machine. I have seen some machines with the S/N on the side plate at the rear of the machine.
Yeah sounds a bit old for what I am doing I'd need a 275b or even c
