Couple times in the past month had a slow crank on some cold starts and some warm restarts, kinda an odd combo. Did all the VOM readings on the battery and thought it's good but now battery 6 years old and not a big deal to change. Bill said i was living on borrowed time. Paid 94 bucks in 2017 for the best at NAPA, 154 the other day for the identical battery, I even weighed them. A couple minor wear/rust spots in the battery box, a POR touch up and done, nice fresh battery and install.
Nothing is that easy, jackstands and a creeper, and headers and, I don't need this.
Almost twenty years ago the original 305 starter gave up, 2004, the T56 and TES headers were on the car. Time for a mini starter to be installed, only 125 bucks for a new mini Hitachi from one of the venders of the day. Had it out a time or two adjusting, shimming the engagement depth of the bendix. It would just kiss, tick, the flywheel ring gear when the crankshaft's end play was forward in the block. More the PITA thing than a problem, most people would never know it was a problem.
I lived with that until the new engine went in, 2007, a new starter, lots of shimming so the new McLeod billet wheel and the new Dart block made ring gear engagement and backlash happy. That was all done before the engine went in the car, on the engine stand. Bought that new starter from another vender of day, it was only 100 bucks. Good starter, no noises, seem like all good to go.
Well in 2011 that combo of parts ended up taking teeth off the ring gear, My thinking was ring gear failure was ring's material's fault. So now time for a a new Ceramix On-Off switch clutch a 700 lb/ft-er, cut the flywheel, new ring gear installed on the McLeod wheel.
Now it's time to buy something better, tired of playing with starters, bought a Powermaster 9000.185 bucks, 2011, the fourth starter in less then 10 years,
Every thing is fine, for about 5 maybe 7 years, 10K mile, and one day, actually several times, the starter has a dead spot.
Now pull that starter out of the car, the PowerMaster, go back to the parts shelf and pull the two previous mini installed in this car and find one is exactly like the Powermaster, the 100 starter. Dissected both of them and found they were identical, only difference was price.
The PowerMaster commutator is junk, brushes junk, the reason for it's demise. The other identical mini has bad teeth on the pinion gear, commutator good, brushes good.
Marry the best of the two and reinstall a refurbished Powermaster 9000, until death do it part,2023.
Well now here in 2023 there are three mini apart on the bench and another round of what to do about a starter.
The commutator on both the PowerMaster and the sister are now junk, most of those two will go to the scrap pile, no need to keep junk anymore. I will reuse the bendix and mount from the PowerMaster on the new starter I'm building. The teeth on the PowerMaster pinion are the best and all three of the mini bendix are identical along with the solenoids, the best of three will go on the next starter.
The original 125 dollar mini installed in 2004 will be the new starter. I believe it is a the high tongue Hitachi because the armature is much longer and the commutator OD is MUCH larger and brushes are very good. The Power Master bendix would like to change the bearing behind the pinion but so far have been stymied by an internal snap ring. The PowerMaster bendix is the only choice to reuse
Some time was spent shopping a mini to see what is being sold for my engine. I've done a $100, a 125, and a 180 starter, next jump is more for a high torque today.
Performance info of starter is at times vague. You surmise it's compression ratio that guides torque production necessary so there is three kinda zones.
Lower, higher, outta here. We mostly fall into the hole between lower and higher. 10 ish where you can maybe get by with the lower end of torque output from a starter. That Powermaster was one of that category, and also that mirror of the PowerMaster.
Will get that old starter bought in 04 back for another round with a little TLC and a little time. Here's is it's duplicate in a PowerMaster 9004.https://www.summitracing.com/parts/pwm-9004
It's not about the money it's about doing it, good parts are laying on the bench. This will be the fifth starter dance for this car. Hoping to get 5 years out of it, let's see, 77, this might be my last starter in this car, I hope.
