New Cat D9H, Finning Vancouver
Did the early H's have the same exhaust as the G's? Vertical like that rather then horizontal.
Yeah, I drove an early model H and it had the muffler like that.
Owned one for several years.................great dozer
The horizontal muffler came out on the new K models. I spent a lot of hours on both.
I should have said newer D9H.
Yeah, I was wondering what I was missing all these years.........never heard of a 9K!! I ran this 8K when it was new........lovely machine!
If you are talking about a D8K No they didn't. Bob
I don't remember running one that didn't have a horizontal muffler. The contractor I worked for had several of them (8K's).
I agree that they were both ways........the one with the picture I posted was a model year 1975 & it had the upright style. I believe the later ones were horizontal, or at least some of them.
The early D8Ks that I put hands on had the horizontal muffler under the hood. There were plenty of heat problems with cracked heads. I believe a kit came out to change the mount to on top of the hood and then the machines came from the factory with the mufflers mounted on the hood. I worked on a few 9G machines and the only H models I saw had the vertical stacks.
The early 8Ks had a exhaust pipe on top of the motor that came up thru the front of the hood to a vertical muffler. The later ones came up thru the back of the hood and the horizonal muffler was on top of the hood. Bob
I removed the mufflers on both my D8K and D9H and just ran straight pipe out.
So what did you do with the dust ejector ? Bob
I do not know, my mechanic at the time did the retrofit. Owned the D8K for 10 years and the D9H for 12. Both were fantastic machines. Other than track work I only had to replace the final drive as a high ticket repair in all those years. the final cost around 20K.
