Description
Call it the front end Freshen Kit. Available in Round (early)or Keyed Rivet(late/Post'76). This is what you need if the Pump group of your Post '78 Benjy or ANY Sheridan has been neglected and you need to put all soft and hard goods in place to get a fresh start. I'd get the Secret Sauce also. Lubed they will last forever. Make sure you mop all the goo out of the front end/inside tube packed against the valve face. On Pre-'62's often the lever link bushing is toast. It wasn't a very robust design and most failed. You will not see it till you take the rivet out. The lever needs to be drilled and beveled 1/4" on one side and a newer round rivet fitted on the earlier models. Early guns had a bad rivet arrangement that needs to be upgraded to 1/4" rivet on link rather than bushing between link and rivet. A rock hard cup indicates much heat. That means no Lube which translates to rusty valve springs and fouled exhaust from rusty muck.
Factory round rivets tended to turn if they were not bucked properly and an oversize Round rivet is what Mac1 sells so the rivet will fill the bevel and engage the lever adequately to eliminate rivet spin. The round rivet should be primarily bucked from the large side while the Mac1 Keyed rivet should be first bucked on the Keyed side.
Includes Pump Cup, lever link rivet, felt bumper, link pivot, Secret Sauce lube & spring pin. If the Pins don't drive firmly into front plug consider getting the Steroid Steel Front Plug. If you have early non-rebuildable Piston, get the Stainless Steel Piston head as well.
There is an Option for Pre-78 Benjamin as well which will service the early guns with the Benjamin cup that pops over a 1/4" center shaft.
