CUSTOM SHOP USA MADE STEEL BAR ADAPTER SHIM FOR FITTING STIHL MEDIUM MOUNT BARS (D025) TO MCCULLOCH 10-SERIES SMALL MOUNT MODEL CHAINSAW  5/16" BAR STUDS - SEE PHOTOS AND/OR VIDEO FOR ITEM DETAILS

USA made custom chainsaw guide bar adapter spacer shim for the American McCulloch 10-series muscle saws of the 1960s and 70s. Designed to fit almost all McCulloch 10-series chainsaws and facilitate using today's pro Stihl pattern guide bars on the beloved vintage iron. Greatly simplifies boosting the power to weight ratio of an old MAC chain saw with a D025 lightweight bar. See below for all McCulloch model fitment information.

Designed to be a slip-fit part on new bar studs, but if your application powerhead has bent or galled studs or a worn bar landing area as most old and well-loved macs do, you may need to fix your bar studs or press on the adapter with a little pressure or tapping action. D025 pattern bar oil slots / holes AND chain tensioner holes will likely need to be widened / modified to properly fit and lubricate.

NOTE: MAC 10-SERIES CHAIN TENSIONER STUD SHOULD BE FLIPPED TO BETTER FIT D025 (STIHL PATTERN) BAR TENSIONER HOLES - SEE PHOTOS & VIDEO

SPECS:

- 0.135" stock steel lazer cut in the United States.
- Adapts 5/16" SAE studs on the small frame 10-series McCulloch model chainsaws to Stihl 12mm D025 bar slots.

NOTE: STEEL FINISH MAY VARY AS SOME FINE FITTING / CLEANING WORK IS DONE BY HAND.

NOTE: IF FITTING TO WELL-USED POWERHEADS WITH GALLED OR BENT BAR STUDS, YOUR STUDS MAY NEED TO BE FIXED OR ADAPTER PRESSED ON WITH SOME PERSUASION.

NOTE: ADAPTER SHIM ADAPTS 5/16" BAR STUDS TO MATCH D025 (Stihl Medium Mount) 12MM SLOTS, BUT DEPENDING ON THE MAKE AND MODEL OF YOUR D025 BAR AND APPLICATION, YOU WILL LIKELY NEED TO CHECK OR CHANGE INTERFACE BETWEEN POWERHEAD OILER PORT, POWERHEAD BAR PLATE, AND OIL HOLE ON GUIDE BAR TO ENSURE PROPER CHAIN LUBRICATION. THIS IS SOMETHING LOGGERS HAVE DONE SINCE CHAINSAWS EXISTED TO DEFEAT PROPRIETARY GUIDE BAR SYSTEMS. SEE SHOWCASE VIDEO FOR DETAILS.
