piman Posted March 29, 2008 Share Posted March 29, 2008 Hello Alex,"certainly worth getting rid of excess endfloat"I would put it far stronger than that, do sort out the end float before boxing everything up, it will only get worse. You can use feeler gauges to judge the amount of clearnace as the sump is off. By the way, you don't need to put different sized thrust washers in as a pair, i.e. if two standard size thrusts still give too much float, the next step up could be one +5thou and a standard.As for checking wear on the crank journals , use very fine wet and dry strips and WD40 etc to clean the journal. You will then be able to check for wear. Your fingers are sensitive enough to detect even small amounts of wear. If you feel any ridging then it needs a re-grind. If any of the shells are worn to the copper it will also need a re-grind, in my experience.Alec Link to comment Share on other sites More sharing options...
Richard B Posted March 29, 2008 Share Posted March 29, 2008 Normally you use a dial gauge mounted on a magnetic bas to measure the end float.£20 dial gauge£15 magnetic baseThen you think oww a set of micrometers would be nice...... Keep an eye on flea-bay. Link to comment Share on other sites More sharing options...

mikeyb Posted March 29, 2008 Share Posted March 29, 2008 Doh, you may be right - I completely failed to put 2+2 together! Makes sense now :-) Is the engine number a high one? If it is then that fits with later TR6 too! Link to comment Share on other sites More sharing options...
Alex Posted March 30, 2008 Author Share Posted March 30, 2008 If I just took the number right its cr6217hes could the s be for sport ie tr6?Would changing the cam...at a later date improve the torque and power output or are we talking negligible amounts on carbs(hs6)?

Alex Posted March 31, 2008 Author Share Posted March 31, 2008 Engine is now just a load of bits so I just need to reassemble.Got a couple of questions..1. Should there only be thrust washers at the rear of crank shaft?2. There doesnt seem to be significant wear in the bores so I'm thinking run a honing tool down them then fit new rings?3. The cranks not showing major wear so I'm thinking just put new bearing in the same size as before?Oh and int it eavy!! Link to comment Share on other sites More sharing options...
Alex Posted March 31, 2008 Author Share Posted March 31, 2008 If I can borrow an engine stand does it bolt to the block or the backplate?Obviously backplates currently removed.Cheers Alex Link to comment Share on other sites More sharing options...
