Here's what I made to pull the driven clutch off my 350 Ody after 3 days of wrestling with the #*+@%^! thing. Tap threads into the 3 holes on the clutch boss face,then fit the puller & bolt it up. Around the collar are a series of holes to take some self tapping screws into the boss curved side for added purchase/load sharing. Screw in center bolt while tapping gently on bolt head.Use lots of spray & heat.
PS. The dodgey welding was due to puller also being used as abstract art lounge ornament
Would you believe earthquake!
