Pullstart 62,954 #1 Posted July 7 Oops! My buddy down the road has this loader/hoe on a D-180. He mounted a Predator 670 to it and it’s a beast! I borrowed it for some digging around here in exchange for mounting up a motorcycle tire. The steering pivot has been greased, but maybe not lately. This bolt seemed quite stuck in there, and the broken part twisted off, getting it quite stuck in the frame. It’s a 1/2” threaded hole. I will work on it tomorrow!

ri702bill 8,392 #2 Posted July 7 Looking at the casting, it sure does look dry. Maybe time to turn a .010 undercut inline with the zerk to spread grease on the replacement pin??? 2 Share this post Link to post Share on other sites
peter lena 8,660 #3 Posted July 7 @ri702bill totally agree with you on the dry lubrication areas , what's up with that ? @Pullstart realise I regularly make a point of it , just sayin , if anyone was to apply ,KROIL TO A DRY MOVEMENT AREA , BEFORE USE / METAL MOVEMENT , you would have a rusty track / trail of rust removal , is that so difficult ? another thing about those D SERIES , is the MECHANICAL STRESS RATIO ,AT JUST ABOUT EVERY POINT . the hydraulics on that will easily over power , any application . that would be like a base line check over on that for me . dare I say it , lucas green grease , 550 flash point , polyurea rated , would have prevented those rusty / dry movement points , just a slight suggestion for a step by step to related failure . pete Share this post Link to post Share on other sites
Achto 27,645 #4 Posted July 7 That steering arm is the Achilles heel on those D's the cast part is pretty fragile for such a beast of a tractor. Jim bumped into a tree with the front tire of Betty & snapped one arm right off. The bolt issue will be fun, but I'm sure you're capable. 1 Share this post Link to post Share on other sites

I’ll get that broken bolt out of the frame, get the rust cleaned up, and check for clearance. Ample grease should help the dry situation. 3 Share this post Link to post Share on other sites

peter lena 8,660 #9 Posted July 7 @Achto AGREE WITH YOU ON THE STEERING ISSUE , think there is some answer in any related size / fit automotive match . you can match up specs on line . rarely leave a failure / trouble spot without a change . pete 1 Share this post Link to post Share on other sites
Pullstart 62,954 #10 Posted July 7 The bushing was hardened and cleaned up well. I gave the grease a little pathway to find itself to the bolt if it were pumped excessively, and gave the rest of the front end a well deserved grease job while I was at it. The excess got pressure washed off after work was completed. 2 2 Share this post Link to post Share on other sites

peter lena 8,660 #12 Posted July 8 @Achto was snoopin around and found a number of similar on ebay , just put in the original part # @Pullstart ; love the green grease . stay at it , pete 1 1 Share this post Link to post Share on other sites
pfrederi 17,747 #13 Posted July 8 If you remove the tie rod ends from the pivot arm be careful and do not over tighten the nuts when you reinstall. That cast iron pivot is brittle you can break it...don't ask how I know that... 4 Share this post Link to post Share on other sites
peter lena 8,660 #14 Posted July 8 @pfrederi often refer to the detailing / watching how your repair is effecting an issue , have found more often than not , along the build up , you find an ease of movement or similar , washers / grease / etc , makes something that was a train wreck , move with ease . that also shows you the INTENDED FUNCTION . prime example , if you take a pull / push point , that only works in a straight line , change the end connection to a HEIM JOINT , suddenly smooth effortless movement , it will TOTALLY move without effort , then snug up , enhance that point , pete Share this post Link to post Share on other sites
Tractorhead 9,064 #15 Posted July 8 It appears to me that all the Pivots is under high load with FEL and a full Bucket. What requires imho a very well greased pivots at all the whole Steering parts. A counterweight is additionally a good idea here. maybe some weight in the Backhoe bucket can do the Trick here to balance the weight ratio between front and back and so destress the Steering parts. 1 Share this post Link to post Share on other sites

If you ever build a steel pivot use a large diameter steel and put ball bearings in it with a spacer like the WH deck spindles. That should make it steer easer. I see why they used a spool, and it lasted 50 years. If you are going to the trouble to build one improve on it. 1 Share this post Link to post Share on other sites
