Walking an area to be cleared for a river view from a new home build site. Noticing the area to be cleared is too steep to maneuver while on the slope except straight down and back up, no turning to chance a possible rollover. Question does the steep angle promote poor cylinder wall lubricating with oil all to one end while going up and down? I know the history of these machines included all types terrain.. still was wondering. And would the use of additives help this issue? 

Thanks Walt. Much appreciated. The one I have is a ‘52 ..  I hope it does have the dual you’re speaking of..maybe  there’ll be more input. 

Hi, JohnnyL.
You don't appear to have mentioned the machine that you will be using for this clearing. That also will make a difference as different machines have different engine lube systems..

Hi Deas,   Same tag # is on motor and back of dozer.

Anyone know what the 734 tag is?

Hi, JohnnyL.
Atta guess, 734 would be a government # at some level of the bureaucracy. Others here will likely know more than me 'coz I'm from DowNunda.

The 3T D7s were a pretty stable machine. Just make sure that your brakes are properly adjusted and working well and keep the blade low - - - or am I preaching to the choir here?

Just my 0.02.

Ha not hardly preaching to the choir.. my experience on this cat has been mostly flat ground. Always appreciate as others I’m sure your.02 on various issues..

Hi, JohnnyL.
Regardless of whether climbing face first or 'bass ackwards', keep the blade low. Face first, it helps to hold the front down. 'Bass ackwards', it tends more to hang from the push trunnions rather than lifting the back end off the ground levering over the front idlers as it would do if it was up high.

Most dozers are remarkably stable sideways on slopes too. The GREAT majority of operators will 'press the chicken switch'. I have personally had a Cat D9N dozer on a MEASURED 43 degree side slope TWICE - different situations and it never felt like it was about to lift the high track. In fact, the second time, I was turning toward the low track all the way trying to get away from a boggy area on the slope and the high track never lost traction, was driving the whole time.

BUTTTT, it'z still best not to push the limits.

But what would I know? I'm 'justa pore, dumm bulldozer op'rator from DowNunda'

Just my 0.02..

Seems like the reverse has as much torque power wise backing as the going forward does. I won’t be horizontal on the steep portion of slope ..
