Rotated steer tires. Swapped on 4 G177s on the rear drive axle with 4 new wheels. I hate powdercoat white so I sprayed em with M.E.K. and then spray painted em black with activator. The MEK makes spray paint stick well.

Swapped on an old HT3B turbo. Had a leakin cartridge seal too. Ordered a new HT4B. Showed up as an HT3B. So I called my local turbo place and ordered a new cartrige and impeller for my old HT4B. Swapped on a cartrige from an Borg Warner S4T and Marine 32cm exhaust housing. The cartrige is also used on the HC5A turbos. She should roll up pretty good on boost. HT4Bs run better at higher rpms like the big cam is running. The combination of parts should allow for 60lbs of boost or so as I have the fuel to run it that high. The transmission won't like it though. Least not the HT754 anyway.

Swapped over to a longer air filter. It was cheaper to run CAT inner and outer filters. CAT. # 246-5009. And 246-5010. Much cheaper than wix. Capable of 2200cfms of air.

Swapped all oil and fuel filters and changed the oil again. Swapped to Fleetguard Venturi type primary filters.


Swapped to a lower temp fan thermal sensor. 190 degree index # 8037022p


Also got a little muddy trying to get out of my yard so I ended up putting the sprinkler on in 50 degree weather and washing it off

Injectors can handle it. Pump is already bumped up.

Busy day.

Turbo swapped. Pulled 42lbs of boost on a test run just Bob tail. Swapped a few other hoses as well.

New air filter.

Swapped in a new steering shaft since mine had some play. Swapped in another steering column with a smaller steering wheel. Much more room.

Put a new puradyn filter housing on.

Replaced fuel filters. Got 20k out of the pump filter this time since I put a 20 micron in front of it. And my drivers side tank has a 10 micron filter that catches stuff when pumped to the primary tank.

Replaced my air lines from the tractor protection valve up to the trailer lines. Installed a new higher pogo stick and spring hanger. Secured the lines to a fixed position with shut off valves.

Well she's been running like usual. She will be getting an upgraded hydraulic pump cause the single 20 is just too slow for as much as I use the winch

More gpm means more speed.

Hauled a friends 50k excavator. It didn't mind it too much except for a few steep places.

She is in the process of hauling some new siblings home. Two 920s and another 916 with the 7spd. All are 2012 rebuilds
