  1. 1916/1917 LIGHT SIX VALVE CAGE SEALING RINGS

    Hi Terry - We got to work on the cages today and they just about fell out. Only needed the puller to make sure they came out straight. No problems at all. The bore in the block is 1.690", the diameter of cage is 1.685" (based on measuring one). It was interesting to speculate why the last mechanic mixed up the valves and cages despite the punch markings being quite visible. Also got our first look down into the cylinders and was heartened to see that they look spotless, no signs of rust. Rick
  2. 1920 Mercer Sporting... 6 owners since new, all within 75 miles of Boston, currently in southern Maine. Original interior, one re-paint around 1940. Enjoyed regularly on the back roads.

    Hi Terry - I have not attempted to remove any of the cages yet, have been letting them steep in ATF and acetone based on advice to proceed with caution. I'll try to tug one out this weekend. Thanks Rick

    Hi Terry - Back to work on our Buick after a business trip. We got the valve cage nuts and sealing rings out. The sealing rings measured 1.692 - 1.700" OD, 1.481 - 1.500" ID and 0.123 - 0.127" thick. Is this close to your light six? Thanks Rick

    The 7th annual Mercer Associates meeting will take place at Hershey on Thursday, October 5th, 3pm at the west end of the Coker Tire tent. As in the past, the meeting is a gathering for owners of Mercer automobiles and honorary members of the Mercer Associates. Looking forward to catching up with all of you on the news from the past year.

    Terry - We got the valve cage nuts out but need to make/modify a puller to get the cages themselves out. Bit of a delay this weekend as priority was getting wheels cleaned up and prepped to drop off with Mr. Calimer at Hershey. Rick

    Hi Terry - A slightly better photo with the cobwebs and other items out of the way...
  8. 1916/1917 LIGHT SIX VALVE CAGE SEALING RINGS

    Hi Terry - Thanks for prompt reply. This is our first antique Buick so is all new to us. Ours is a 1915 with non-removable heads. Engine is out of the car now and turns over easily but have not attempted to removed the valve cages yet. Previous servicemen seem to have used crude instruments on installation/removal of the valve cage nuts. Will try to get one of the valves out and apart this weekend. Thanks again, Rick

    Hello Terry - I picked up a 1915 C-25 in July that came out a of barn in New Hampshire. My son and I in the process of tearing it down with the intent of rebuilding as a speedster. I would be very interested in a set of cage nuts and sealing rings if they would fit the small 4 cyl engine. Thanks! Rick

    Looks like some customization with the running boards removed, cycle fenders and forward spare mounting. Perhaps the work of George Bentel's shop.

    Also - wear your M E R C E R sweater for the group photo if you purchased one through Clifford Zink.

Stop by to catch up with fellow Mercer owners and enthusiasts.
  14. Camshaft repair regrinding

    Thanks Ivan - The exhaust roller on #4 cylinder got chewed up and damaged the cam lobe. This may have been due in part to excess wear of the cam shaft thrust bearing (center die cast bearings?) which has allowed it to shift aft 0.125-0.150", or by some mis-assembly of the cam shaft by a previous owner. This is evidenced as the front timing chain gear seems to be in the right plane with the crank and tensioner, and the front tip of the cam shaft is recessed in the bronze cross shaft gear. Either way this would have reduced the contact area and in turn increased the contact stresses. The material from the roller has come off in little chips, some of which have found their way into the pan, so I think I am into a compete rebuild. I also noticed that #4 EXT valve may have been sticky which would not have helped the situation. I have ordered a new set of valves and guides from the gentleman who has made some recently for Fred H. Fred is also in the process of getting new rollers for a client's engine.
  15. Camshaft repair regrinding

    I have a 1920 era 4 cyl engine with roller lifters. One of the rollers was apparently stuck and damaged the adjacent camshaft lobe. I also have a spare camshaft but some of the lobes have significant rust pitting. Does anyone have (successful) experience having camshaft lobes welded and reground to the original profile? Are there issues getting repaired lobes to sufficient hardness? Special heat treat or coatings (parkerizing)needed? Long term any issues with fatigue/cracking? Thanks for any advice/recommendations
