I need to create a list of items to check for a loader I am going to inspect for a pending purchase..
I have the common items but need items specific to the straight 350 model.
It has the 93 series backhoe with the Drott 4 in bucket.
I am familiar with dozers, but NOT with the backhoe and loader options.
It appears the loader and backhoe would put ALOT of stress on the small frame of the 350 unit.. Tell me where the weak points are so I can inspect them.
350 items
1. Track plates, pins, rollers, rock guards, sprockets, rails
2. Clutches and brakes
turn right and left up hill and down
check all gears
check dash mounted reverser
stick the blade and see if track spin or stall
lift the unit with the loader and backhoe. test for leak down
4. engine, charging, overheating, blow-by, fluid leaks...etc
Model specific inspection Items.
5. Clutch housing bolts-broken or missing
6. Cross over bar broken bolts
7. Backhoe......?
8. Loader.........?
9. Frame cracks....?
Can the 350 frame really stand up to the loads of the loader and backhoe?

Hi,
One thing I've always seen is that the flanges on the #5 (rear) and #4 rollers on each side wind up cracked off. Sometimes they're also missing on #3.
I suspect it's a progressive failure mode caused by the side loads generated by the backhoe.
Of course, it means that as time goes on, there's an ever increasing load placed onto the sides of the sprocket teeth, and then also everything else associated with the final drive.
I'd take a much longer and harder look at those parts on a loader/backhoe than I would a dozer.
In fact, I recently looked at a 67 JD350 loader/backhoe that had all new everything on both sides a few years ago. It was a private machine on a farm, and he'd spent the big bucks on the rebuild. Yet, it had already fractured the flanges off both sides of both #5 rollers even though it didn't get much usage after the new parts had been installed.
later!

The roller flanges are the "lips" on the rollers that ride below the tops of the rails. They can be found just behind the rock guards.
