1450 ACR question

[cubcadet100]

Every once in a while my 1450 wont turn over i put a new battery in it, when it comes up on compression it stops if i bump it a few times it will go. I have 2 1450s and they both do the same thing is there an adjustment or somthing gone bad, im not sure how the thing works just wanted to get some advice before i tear into it. Thanks

Before blaming the ACR, I'd try some easier things first.

1. Check/clean all of the ground cables, including the one from the tractor frame to the engine. Replace any cables that appear to be in poor condition.

2. Remove and clean the starter, paying particular attention to the condition of the brushes and commutator.

3. Are these tractors sitting outside or inside? If you are using 30W oil this time of year, they are going to be very stiff. 10W-30 needs to be used below 30 degrees. If they're outside, a magnetic heater on the trans would be a good idea. The trans is also very stiff when all of the Hytran is cold.

My 1250 acted the exact same way. While I had the head off I checked the ACR and it was working fine. I had cleaned and double checked all the wiring while I had the motor out. The only thing I did not do was check the starter. I am almost positive the starter needed going thru.

I took the starter apart on my 1250 and used an electrical cleaner on the internals and where it attached to the engine block. I was surprised how much dirt came off. Then I used a silicon lubricant on the bushings and bendix. after I put it together it spun noticeably faster. Also my wires need to be replaced, they are still the original wires.
