Tools Used:

Socket set, Wrench Set, allen wrench, gear puller, feeler guage

coupler between engine and hydraulic pump broke

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.

Bad engineering design: self destructing spacer between engine & pump.

1. Separate main frame from splitter , including hydraulic hoses.
2.Contain hydraulic oil.
3. Separate engine from pump.
4. Remove couplings w/ spider spacer. 1/8" Allen wrench required (maybe rust blaster) for set screws.
5. Secure woodruff keys from each coupling half.
6.Steel wool & bearing grease pump & engine shafts.
7.Reinstall new couplings with set screws not tight.
8.Lower engine to pump. Pump has Spider spacer on its coupling. Jiggle to interlock couplings.
9.Reposition engine & pump frame(main frame w/ wheels) to set .02-.09 gauge space. Hard to do.
10.Tighten set screws(70#) w/ Allen wrench. Grease in Woodruff slots can fool you on tightness.
11.Secure engine to main frame. Reconnect hoses. Check hydraulic oil. Start engine.
12. Engine pull start will be "stiff" at first.
13. Exercise splitter 10-12 times.
Recheck oil.
14. Double check set screw tightness after a little splitting.
