Hi all:
I'm new to heavy equipment, and bought the 935C two years ago to clear brush/dig basement/trenches on my small acreage. Finally started to use it this spring for about four hours, and issues have cropped up. Hope someone can provide advice:
Engine: Starts and runs well at idle or fast. But...there is a very loud but random sharp metallic clank that sounds like a loose piece of sheet metal is being thrown about by a rotating mass. I thought it might be some sheet metal hitting the alternator belt/pulley and being thrown about, but everything appears tight under the hood. Could it be something loose in the muffler (outside has no rust), or, I hate to suggest, something in the engine itself such as broken rings or springs? Once engine is warm, the clank seems to die off. I also noted that when working hard pushing dirt, the black exhaust seems to come out through the front rather than the stack....
Transmission: Two days ago, while pushing brush and dirt, I felt a bit of a shudder and within a few minutes there was no more forward or reverse--only a vibration in the floor pan when in gear. I was 300 ft into the bush from my staging area, and spent four hours clawing the machine backwards with the backhoe on a curvy path around big trees. I'm thinking stripped gears, but I hope someone has a less expensive diagnosis
Hydraulic Fluid Loss: While dragging the machine out of the bush, the backhoe hydraulics were suddenly less than effective--stick and boom hardly worked, and I had to use the backhoe bucket to do the pulling. I soon discovered the fluid tank was very low. I haven't seen any major amounts of oil on the ground, but I have to admit I didn't check the reservoir prior to starting work--previous owner said all fluids were topped up and ready to go. I'll have to fill it and check for major leaks, but I would like someone who knows to confirm that the transmission and hydraulic fluids are not related on this machine....
I have a service manual enroute, thanks to eBay, but all repairs will have to be done by real mechanic$ til I get a shop built on the property.
Thanks for your advice!
