The bearings/bushings in the starter wear and the clearances get really small when the starter is cold, but when it gets hot the clearances go away and the starter's armature drags. This causes the engine to crank very slowly. > > You can take the starter into your local parts store for testing, but their test doesn't always find the problem since the starter is cold.

Ford went to them in the years after our trucks were built, so you could get one for a later truck. They have more power than the one your truck probably has. > Gary, AKA "Gary fellow": Profile > Dad's: '81 F150 Ranger XLT 4x4: Down for restomod: Full-roller "stroked 351M" w/Trick Flow heads & intake, EEC-V SEFI/E4OD/3.50 gears w/Kevlar clutches > Blue: 2015 F150 Platinum 4x4 SuperCrew wearing Blue Jeans & sporting a 3.5L EB & Max Tow > Big Blue: 1985 F250HD 4x4: 460/ZF5/3.55's, D60 w/Ox locker in front & 10.25 Spicer/Trutrac in back, & EEC-V MAF/SEFI > > > > If you reply to this email, your message will be added to the discussion below: > http://forum.garysgaragemahal.com/84-xlt-starter-issues-after-running-for-a-few-minutes-tp61682p61709.html > To unsubscribe from 84 xlt starter issues after running for a few minutes, click here. > NAML

hello Jim, thank you. possibly bad cables, starter, bad connections seem to be what i read about most also. much appreciated. bill

hello, new member here. thank you in advance for any help you may offer. i have a 1984 xlt with 351w and automatic transmission. just purchased it last week off auction. after running engine/driving for a few minutes and then shutting it off, and the engine does runs strong, it won't turn over until a cool down period goes by. battery has plenty of power, but starter turns super slow in this waiting time. after it sits for a while it starts back up and turns strong. outside temperature has ranged over the last week between 75 degrees Fahrenheit and 102 degrees Fahrenheit. any historical known issues like the one above with these bullnose broncos and 351w engines? regards to all, Bronco Bill
