coupler between engine and hydraulic pump broke
Earl - November 26, 2020
Tool Type
Log Splitter
Difficulty
Medium
Time
30-60 minutes
Tools Used
Socket set, Wrench Set, allen wrench, gear puller, feeler guage
Removed engine and pump mounting for gear access. loosened set screws with allen wrench and used gear puller to remove both couplers, one from engine and one from hydraulic pump. Replaced in reverse order, tapping couplers lightly in exact position of old ones and adding spider bushing between couplers. When bolted together, make sure there is 0.15 to 0.25 between couplers with feeler gauge. Loosen set screws and set adjustment if necessary.
Special note: remove couplers to check shaft sizes before ordering as at least three different sizes are available. Shaft sizes are stamped on couplers.
