I tried to buy a roller tonight at my loacl chandlers, all they had was the coned shape ones at £12 a shot ouch !! and they didnt look as though it would be long enought to reach across both sides of the engine support.
Where did you get yours and what sort of roller is your ?
Had one other idea looking at yours, i could buy one and cut it in two, then bolt each piece at the correct points along the shaft to marry up to the supports as the engine is lowered down.... would this work, alternative is two rollers bolted back to back on the shaft !! but this is gona cost more and still might not work out right
what do you suggest
