Of course the piston at one side would be farther extended than the other if the pad thickness was different, doesn’t mean the pistons are frozen, any caliper requires the piston to be compressed to install new pads. it’s not uncommon also for one pad to wear different than the other, but verify...

there is no issue here…v-belts regardless of matched set or not will bounce around at idle.

If your taking a voltage reading from the rear battery while engine is running, of course you have 14.5 volts, the 14v tap feeds the rear battery off the regulator, it’s designed this way to prevent an inbalance due to the draw from the TCM and other 12v accessorie.

Do you know why the grease is used? Do you know where the grease is applied? Someone better tell the soldiers to stop using grease, RTV and god knows what else, I do a set of RF’s every week unfortunately and it’s always fun to see what was done by the previous installer.

Than don’t….

the correct RF grease is water-soluble, you can use any axle grease if you must, I don’t use anything, never have.

not much to expand on, I just use my 3/8 long handled wratchet.

No special tools, I do a belt about every 4 days on these serp systems…

Take your pick…just imparting my .25 cents.

Huh? Where did I mention 60amp serpentine? as I’ve previously stated “unsuccessfully it appears“ you have 2 options for your pulley, the current small pulley or the larger clutch pulley.

Tachometer is fed from the generator ,not the PCB…sounds like a failing regulator.

you only have to go to our company FB page to see over a year ago the write I did on this very issue, that and the other numerous 400’s removed and replaced with 200amp. Ive posted many photos of the damage these 400’s can cause and have caused… unfortunately folks don’t like my answer’s when I...

Looks good to me…turbos run at 220 before fan clutch kicks in, verify at some point it’s working and fan turns on and off as it should.

There are drain plugs on the block to drain the water jacket, pull the cold advance, pull the temp sending unit…you will get plenty of coolant, but the block plugs are at the bottom, so you get everything

Here is what I know, anyone who owns or owned an A2 truck ”2.73” and than hops into a ECV/REV truck, will immediately think they are missing the overdrive gear…

indicated RPM’s and pulley size is a major factor, I’ve already done this circle jerk over a year ago. The diffs are 3.08, thats the only diff used in an ECV…its not an unknown.

One of the more confusing pages of the install of a 400amp…”if you already have a pulley, install it”, as far as I know, only the clutch pulley is and was ever used on ECV 200amp’s, so no mention of how that smaller fixed pulley got introduced. Also, for anyone installing a cLuther pulley, the...

smaller pulley will yield higher rpm’s than a larger pulley, there are only 2 pulleys. a quick trip to the proper TM would yield results.

Guys, the 400amp uses either a fixed pulley “smaller”or the “Clutching“ pulley just depends on what you got from auction. I’ve found it’s hit or miss what you get, The clutch pulley is larger, thus the indicated rpm’s is lower. Reason is simple for smaller pulley , The Gen puts out 185 amps at...

GEP discontinued production of the P400, I also know of none ever being used in hmmwv production.
