To Butcher or Not to Butcher (a Crankshaft)

[Richard Milhous]

I have an old Murray push with a Briggs 95902, 1992 vintage. The starter pulley wore out where the recoil spring goes in, causing the spring to come loose and get scrambled up in its housing. I found a new spring and pulley, but can't get the spring to stay seated in the shroud.

I can't find a part number for the shroud or even the whole shroud/starter assembly. I have a good shroud/starter off another carcass, but the pulleys and the connections to the flywheel are different. The worn out shroud (Exhibit A) has a 4" pulley that takes the old squarish ratchet cog on the flywheel. The good one (Exhibit B) has a 4.5" pulley from pawls come out when it's rotated to engage a fixed cup on the flywheel (Exhibit C).

I thought I would just replace the ratcheting cog (Exhibit D) with the cup, or at worst swap out the whole flywheel, but the dang crankshaft on the one I'm trying to fix has a mandrel that goes into the ratchet (Exhibit E). I'm tempted to slice it off and use the other shroud, but before I do anything so permanent I thought I'd ask if anyone...

(1) Knows a way to replace the old shroud;

(2) Knows a reason not to slice that mandrel off the crank;

(3) Has a better idea for solving this problem.

The remove of the shaft was an approved way of fitting new engine shroud when replacing the old style starter clutches.

The following instructions are for the 130000 series but should give you the idea of what is needed to be done.

View attachment 58456 Mine was easier than that; all I had to do was pull the flywheel, saw the mandrel off, and put the other parts on. It spins the motor and rewinds. ​
