Matt306 Posted July 13, 2020 Share Posted July 13, 2020 Still fixing my '82 DHC . All progressing, carbs rebuilt water pump done. New Rear deck installed Holes in Spare wheel well repaired. Bottom of B Post repaired. I have a new fuel tank and fuel line to install. Refurbed back axle going in soon. I moved onto dash and heater . I noticed the levers on the heater controls weren't working one flap being seized. This has meant the at the lever end the operating cam has worked off the splined shaft. I cant see anything to secure it on , how is the cam secured on the splined shaft? Quote Link to comment Share on other sites More sharing options...
Howard Posted July 13, 2020 Share Posted July 13, 2020 Matt, Exactly which one is stuck? Its not an easy fix, but it is possible if you have plenty of patience. I suspect its the actuating mechanism that has slipped and then catches behind the cam making it appear to be stuck. Trying to force it damages the mechanism so be careful until you are sure what you are doing. Cheers H Quote Link to comment Share on other sites More sharing options...
Matt306 Posted July 14, 2020 Author Share Posted July 14, 2020 Howard it was the far right lever think it has had a leak at some point as the matrix has signs of a leak. The pipes have a hole too so new matrix from Robsport coming today, The flaps now move as i have opened it all up , the flaps need a paint and some foams. The lever has come off the splined shaft at the control just wondering how these are secure on? Quote Link to comment Share on other sites More sharing options...
Howard Posted July 14, 2020 Share Posted July 14, 2020 Its just a push fit - last time I had to use a clamp to force it home. Photo attached for reference. Quote Link to comment Share on other sites More sharing options...
Matt306 Posted July 18, 2020 Author Share Posted July 18, 2020 Thats the bit Howard, a clamp aaah I'll try that. At the moment its out and in pieces, going to replace the foams on the flaps, got a new heater matrix from Robsport, but i have come to the conclusion the pipes are knackered too.

Howard Posted July 18, 2020 Share Posted July 18, 2020 Matt, when you reassemble the mechanism be careful that the cam that is linked to the flap does not disengage with the operating lever & get trapped. It a pain to adjust after installation, as I discovered the hard way. Cheers Howard Quote Link to comment Share on other sites More sharing options...
Matt306 Posted July 21, 2020 Author Share Posted July 21, 2020 Ahh that one was disengaged i think its the intake flap? The demist direction vent on mine was siezed think thats what caused the lever to pop off the shaft It will all be moving freely when reassembled and free from leaks! The bulkhead seal I will make my own as it appears it isnt available Quote Link to comment Share on other sites More sharing options...
Beans Posted July 24, 2020 Share Posted July 24, 2020 I cut that seal from a closed cell EPDM rubber foam (using modern computer controlled tools) Quote Link to comment Share on other sites More sharing options...
Matt306 Posted August 4, 2020 Author Share Posted August 4, 2020 Quoted from Beans- I cut that seal from a closed cell EPDM rubber foam (using modern computer controlled tools) Looks very good, mine is a bit more rudimentary, neoprene foam cut to size with craft knife. The old one was my template. Quote Link to comment Share on other sites More sharing options...
