240260280 Posted March 21, 2018 Share #49 Posted March 21, 2018 Here is a design aspect to consider... heat shield with additional tabs between carb and head to divert heat upward. A bit tricky because of congestion and access to carb mounting bolts. Link to comment Share on other sites More sharing options...
240260280 Posted March 21, 2018 Share #50 Posted March 21, 2018 Heat resistant silicon on top of shield below carbs will reduce radiation into carb fuel bowls Link to comment Share on other sites More sharing options...
moelk Posted March 21, 2018 Share #51 Posted March 21, 2018 I will be using some kind of heat resistant material on the underside of the shield. Link to comment Share on other sites More sharing options...
Dave WM Posted March 21, 2018 Share #52 Posted March 21, 2018 (edited) removed heat shield I had transferred over from the OE muffler. I was no able to fit the new one inside all the rest of the shield but for some reason left one bit on. It would vibrate and make odd sounds. Thought I had something loose back there, but that was it. I kept all the OE stuff including the bad muffler just in case I can find one that is thin enough to go inside the OE shield. pipe is good, just had some holes along the bottom of the original.

moelk Posted March 23, 2018 Share #53 Posted March 23, 2018 (edited) Some progress today. Need to bend the sides up and do some polishing etc. Edited March 23, 2018 by moelk 2 Link to comment Share on other sites More sharing options...
moelk Posted March 25, 2018 Share #54 Posted March 25, 2018 Well, total cost was $0 so I’d say it came out looking ok. Just need to give it a good polish and get some heat resistant material for the underside. 1 Link to comment Share on other sites More sharing options...
240260280 Posted March 26, 2018 Share #55 Posted March 26, 2018 "Painted" my buddies L26 block with phosphoric acid in preparation for real paint. Currently -2C now but 8C and sunny tomorrow. Link to comment Share on other sites More sharing options...
240260280 Posted April 1, 2018 Share #56 Posted April 1, 2018 Installed crank for first time. Took a while taking all of the measurements of the journals and bearings but all was in spec and. Even the crank float was in the middle of the range. The hardest part was just the rear main side seals. Guy that anaerobic sealant is fluorescent pink! Crank turns silky smooth by hand. I have to pick up rod bolts from MSA when in Oregon to finish the job. Pistons are waiting. 1 Link to comment Share on other sites More sharing options...
Diseazd Posted April 1, 2018 Share #57 Posted April 1, 2018 Blue....The rear side seals are easy if you 1) Apply sealant sparingly as shown in the factory service manual. 2) Align the rear bearing cap (with sealant applied, but no side seals yet). 3) pull down the rear bearing cap until you are 3/4” from bottoming 4) install each side seal and push all the way down till it bottoms out against the block. 5) pull down the rear bearing cap with the two bolts until it bottoms out. 6) Torque all bottoms end caps sequentially (starting in the middle and working out) until torque specs are met. This will pull down the side seals securely without creating a blockage by pushing the side seals against the sealant. Finally, put a small dab of sealant on the top of the side seals before installing the pan. Guy 2 Link to comment Share on other sites More sharing options...
240260280 Posted April 1, 2018 Share #58 Posted April 1, 2018 Excellent tips! Thanks. This is the one that I missed that would have helped: 3) pull down the rear bearing cap until you are 3/4” from bottoming I had read to never pull the caps down in the Monroe of Honsowetz but I think it is needed for the last cap. I'll do it on my next rebuild for sure! Link to comment Share on other sites More sharing options...
