Engine specs for T25 DG anyone?
Posted: 06 Jun 2012, 13:16
Hi all,
I had engine problems last year which were incorrectly identified as big end failure. This resulted in me stripping, cleaning and re-building the engine with no faults identified!
Anyway...after re-building (replacing all bearings etc), the engine fired up first time and ran fine.......until it got to temperature, when the oil pressure was lost!
I tried all the usual things, oil flush & changes, relief valve check, new larger capacity pump, manual gauge directly fitted to the engine, change of two suspect tappets etc etc......
After all of this I have pulled out and stripped the engine down again and measured all the oil system parts (bearings, case, pump, tappets etc etc...)
I want to see if there is any wear anywhere but need the dimensions and tolerances to do this. I have the crank sizes from the factory manual that I have but cannot find the case dimensions to check the clearances between the bearing Outer Diameters and the case Inner Diameters.
so.....does anyone have or know where I can get these?
Also, the gap between the number two main shells seems to be quite large at about 0.5mm, when cases are assembled without the crank. Is this design or not????
any help is much appreciated as the summer will come and go again without using the van!
