Can anyone tell me the difference between a oval muffler( it's what's spec'd for this diesel) compared to a straight round muffler that's on it?
I have a large oval cutout from my hood where a oval muffler should be...

most oval mufflers are 3 pass back and forth and end up being quieter than the round mufflers that are normally straight thru ( with a baffle).
Like them all, but love the "B"s.

Fresh fuel and take it out and work it may clean it up a lot.

In addition to that, working a tractor that has been "setting" can loosen up some stuck or tarnished rings.... that might help you also.

Why would someone that owned this before me have put studs/nuts on in place of regular bolts on 17.5L-24 r4 rear tires only on one side? ( One side of rear is standard original bolt heads other side of rear is large studs and nuts holding rim on?)
It doesn't really matter, I need to remove both to get new rubber on them that came with it that i plan on using rear outriggers to raise up enough to get off tractor and put large timbers under machine to block it up while there being changed but I just don't see why someone would do this and I dought it came this way from factory?( one with studs,one with bolts)
Thanks Matt
Thanks Matt

I bet you're right because they are a larger diameter stud than what the bolt would be I'm only assuming because the nut on the stud is inch and a 16th and the bolt head is only 7/8

Either or both work well but they have to remain tight. When you have it apart look at both rims to ensure the seating areas are not compromised from being run loose.

5/8 bolts have 15/16 heads on them, and standard nuts..... "heavy" nuts for 5/8 bolts are 1-1/16 head.

if it is actually 7/8 head, that is a "heavy" 1/2 inch bolt (standard is 3/4")

Oh I know they will work but it was just me wondering why it would be that way. They are 7/8 headed bolts and the one rear tire is one and a 16th nuts on studs

All four wheels have a center hub that there is a raised part that they are on. Any tips for getting them loose?
