This is a Caterpillar 793C rear axle support, or A-Frame as we call it. We repair these A-Frames by either welding & machining the hitch pin bore or by completely cutting the bore end out & welding a new yoke in place. After we get the hitch pin bore squared away by machining or by [...]
Here’s some parts we picked up for rebuilding. The radiator is off a Caterpillar 793C haul truck as well as the wishbone piece on the back of the trailer. The wishbone is the rear axle support which we refer to as an a-frame. Underneath the a-frame is a heat exchanger that is plugged internally & [...]
This is a delivery we made to one of our mining customers of a heat exchanger oil cooler & a Caterpillar 793C A-Frame assembly. The hitch pin bore was broke out on the a-frame. So we cut the yoke end out of the two support legs & welded in a new #229-7378 yoke assembly. The [...]
Here's some Trunnion Supports & a Pinion Support we repaired. These parts are off of Loaders & RTD's (Rubber Tire Dozers). The trunnions come in with the bores, flanges & surfaces worn & fretted (pitted). We first machine all the surfaces & machine all the bores so they can be welded back up. We then [...]
This is a 3208 Caterpillar V8 diesel engine out of a V550D Tire Handler. The engine came in all in pieces in a couple of boxes. The cylinders were worn, the deck heights of the block were both below the minimum & the heads were also below the minimum thicknesses. We sourced a replacement block [...]
This is the Caterpillar 834H hardnose, or nosecone, cooling package we picked up & posted earlier this week. We got all the modular AMOCS radiator cores, oil coolers & air-to-air coolers all cleaned, repaired, rebuilt or replaced & re-installed into the hardnose. The hydraulic fan motor was replaced as well as all the hydraulic hoses. [...]
This is the hardnose, or nosecone, cooling package off of a Caterpillar 834H we picked up for a complete repair & rebuild. All the cooling system components will be removed for cleaning, pressure testing, repair & re-pressure testing before final re-assembly of all the components back into the hardnose. Motor Mission Machine & Radiator 5435 [...]
This is a carrier off of a Caterpillar 16G grader circle. The carrier goes between the blade, or moldboard, & the circle assembly so it takes a pretty good beating. The bores were worn & kinda welded but not all the way around with a bore welder. So we first machine the bores a bit [...]
Here’s some pics of a Caterpillar 993K loader hardnose cooling package we're in the process of repairing & rebuilding. The upper left rear corner of the hardnose, or nosecone, had some damage. We ended up cutting the damaged section out to straighten it & then welded it back in place. In these pics the Caterpillar [...]
Here’s some pics of a Caterpillar 993K loader hardnose, or nosecone, cooling package that's in for a complete overhaul. The oil coolers are leaking which has caused some major build up of dirt & mud within the fins of the eighteen modular AMOCS radiator cores externally. In addition to the external plugging, there is an [...]
