| yep i understand, in the cab on the dash is the meter, when it reaches 8 on the mtr the blow off valve is released, there are no air leaks to the system, so i have shut of the engine, gone round the back of mog un done the air suply to the top of the diff casing, an then pulled diff engage lever, air is flying out, i am guessing that if the front diff is engaged an working that the rear should also.. Am thinking that am going to have to take it apart an see the condition of the diff seals!was hoping not to have to do this, is there anything i should do before this is the nxt step. I also do not have a drain plug on axle diff casing for draining condensation, front or rear, have crawled all round an its just not there.. My machine is a 1968,ish model 406, u900.. |
