dusted800 1 #1 Posted August 28, 2016 picked up a 78 D160 with the onan engine that needs a crankshaft and piston. the numbers on the tag is BF-MS 3268F. I have been looking around my local craigslist and see a lot of onan engines for sale and also parts. If I find a engine with the same letters (BF MS) does that mean the parts will fit my engine? Any help on this? thanks wk. Share this post Link to post Share on other sites
boomers_influence 106 #2 Posted August 28, 2016 dusted a matching spec # 3268F will not GUARANTEE a match. you NEVER know who was in there before. ( over size 3 1/8 bore or switched to the 3 1/4 bore ) casting # do help, BUT they could still be oversize parts. 651 437 2826 M-F 10-7 S-S 12-6 cent time boomers_influence@yahoo.com thank you boomer ( the used onan engine parts guy, also NOS and new ) Share this post Link to post Share on other sites
