Hello. I'm new to the site this week.I just picked up 1947 D2 and I need to put new seals in the Hydraulic cylinders for the Blade. Does anyone know if there is a Caterpillar kit available for this and if so the P/N please.

Probably only need to adjust the chevron packings.

provided the shafts are pitted or scored yes nipping them up could work. if the shafts are pitted or scored the cheapest option is ta have a new bit of bright chrome shaft welded to the existing rod eye and fit new seals.

I have applied a metal fiber epoxy on pitting and scores and has lasted well so far

Thanks everyone. Busy times so just getting back on the D2 maintenance. The cinch/adjustment nuts on the Cylinder packing collars were pretty loose. I would estimate maybe 10 ft lbs. I gave them an even half turn on each so now approx 20 ft lbs. Maybe I will get lucky. Need to add some hydraulic fluid and I was reading another post regarding hydraulic fluid type. I have a generic hydraulic fluid for drives, power steering systems etc. I will top up with that and change it all when I get the leaks solved.

we use a universal tractor transmission,hydrualics and differential oil in ours. caltex textrans tdh it was developed for the trans final drives and hydraulics of caseih/austoft sugar cane harvesting machinery. it has cat to-4 approval and works just fine in the hydrualics and transmission. its also good in most wheeled tractor drivelines too.
