SaL12-70C Hartzell Generator Conversion Kit

I ordered this on a Tuesday and it arrived on Wednesday. The kit is nice and installation was easy. The bad part was that the regulator was defective from the factory. Plane power was helpful and shipped one out overnight air and I got it the next day. This still required a 150 mile roundtrip for me to install it again, and an extra hour of my A&Ps time to get it running. After that it seems to be working. I hope the new regulator hold up.

quality product and fast delivery

Better then I expected.

Great product easy installation

Installed this in a 1957 172 with O300 that had a generator. I like to fly at night and taxiing with all the lights and strobes running, near idle, will drain your battery in a blink of an eye. Bought this kit for around $800 when my antique $400 regulator died. It was either spend $400 to get back to square 1, or spend $800 and get brand new technology. A&P and I installed together. Installation was pretty easy. Access was easier than any car alternator Ive done. Hardest part was knocking a stubborn, but required bushing off the generator shaft, that was needed for the alt shaft. Plenty of instructions and diagrams, made wiring easy. Included regulator is light-years ahead of what it replaced. Did need to buy a few separate parts for this. I forget what, but its listed in the online install instructions. Youll need wire and circuit breakers, too. Spruce had everything in stock. Alternator comes alive around 600-700 rpm, much better than the gen at well over 1000 rpm. Voltage is rock solid in flight or on the ground, with literally everything running. Voltage adjustment is super easy. Weight savings was over 6 lbs. I did put an alternator noise filter on it, thinking it would reduce some static I hear at idle. I think it ended up being in the intercom, though.

A lot of rewiring to do, but I guess it’s nice. Just wish there was an alternative to spending almost two grand

Best conversion for my N35 bonanza with IO 470. Removed the old conversion that continued to show me signes older technologys proove why we need innovations in Gereral aviation. Install took 2 hours, due to, I change all the wiring. (Would have been less than 1 hour). 1 issue was the center thru bolt clearance on the engine bracket. Had to grind 0.080 slot adjacent to bolt head to allow bolt rotation for tightening this bolt. (Very minor blending though) . Alternator performance is excellent. Voltage regulator is simple and had spot on voltage, extremely stable. I should of installed this conversion a long time ago.

The kit is as advertised. All you need. The pulley is narrower than stock and the belt rides high with a stock 31.19 Continental belt. This is my only concern.

Overpriced non fitting mount bad engineering poor instruction different for kit to alternator to voltage regulator. This is what happens when we sell our US companies. And 2-3 times the price for all their parts just after it was sold.

Im in the process of installing on my PA-20 and Ive run into two issues so far: 1) Some of the parts didnt fit and needed adjustment to work. Specifically, the aluminum spacer (PN 10-1009) wouldnt fit in the alternators housing. I suspect that there was too much pressure from the tailstock when this part was turned on a lathe, which caused the end to flair out. It was bad enough that I had to chuck it in my own lathe to fix it. It was an easy fix for me, but would have been frustrating without a lathe. Regardless, I shouldnt have to fix ANYTHING if Im spending $1500 for this product. 2) The kit included ring terminals but they are too small to fit the studs on the alternator. It looks like the ring terminals are for #6 screws but the terminals on the alternator look to be #8. I am frustrated that I have to put the install on hold until the correct terminals arrive in the mail. For $1500, Id expect that the manufacturer would kit the correct components to complete the install.

Despite calling Hartzell engine tech. And ordering the suggested kit it was missing parts, and doesnt fit the product disription

Ordered kit to replace generator system with alternator system in a PA 30 B. Kit showed up without alternator brackets. After install system didnt work and discovered new version of instructions changed and not accurate wrt wiring. Also instructions so generic they were basically useless. Took scores of shop hours to rectify. Then we discovered the props had to be dropped to replace belts that were shorter for new alternators. Absolutely no mention of this in the instructions.. extremely disappointed and costly mistake buying this kit. And of course no offer of help from plane power.
