Choosing the right starter for your Cat wheel loader comes down to a single question: which loader do you own? In the loaders and skid steers category, a replacement starter has to match the machine it bolts onto, and these two Total Power Parts starters are labeled for different applications. One is for the 920, 930, 936, 950B, 966C, and 966D models from 1969 to 1984. The other is for the 980 and 980B models from 1966 to 1983, with the Caterpillar 3306 engine called out in the title. The decision hinges on your loader family.
Quick verdict
If your loader is a 920, 930, 936, 950B, 966C, or 966D built between 1969 and 1984, choose the Starter for Caterpillar Wheel Loader 920 930 936 950 B 966C 966D 1969-1984. If your machine is a 980 or 980B from 1966 to 1983 with a Caterpillar 3306 engine, choose the Starter for Caterpillar WHEEL Loader 980 980B 1966-1983 Caterpillar 3306 Engine. Both are new units at the same listed price, so the loader model is the deciding factor.

Which one wins where
The Starter for Cat 920-966D is the better pick when you need coverage for the 920 through 966D model family built between 1969 and 1984. The title lists a broader set of loader model numbers, so it is the one to match if your fleet includes one of those machines.
The Starter for Cat 980/980B is the stronger match when you own a 980 or 980B from 1966 to 1983. The title specifically names the Caterpillar 3306 engine, which can simplify the decision if you already know your loader has that engine.
Product notes
Starter for Caterpillar Wheel Loader 920 930 936 950 B 966C 966D 1969-1984
This Total Power Parts starter is aimed at a wide range of mid-size Cat wheel loaders. The title covers the 920, 930, 936, 950B, 966C, and 966D, and the year range runs from 1969 through 1984. The listing also shows interchange part numbers such as 10461242 and 110999, plus manufacturer part number 410-12051. If you own one of those loader models, this is the unit to grab. The one caveat is that the title builds the compatibility case around loader model numbers rather than a named engine, so you'll want to confirm that your loader falls within the listed model and year range before purchase.
Starter for Caterpillar WHEEL Loader 980 980B 1966-1983 Caterpillar 3306 Engine
This new Total Power Parts starter targets the bigger 980 and 980B wheel loaders built between 1966 and 1983. What sets it apart is the explicit Caterpillar 3306 engine call-out in the title, which gives you a clear compatibility signal if your machine uses that engine. The listing shares the same interchange part numbers and manufacturer part number 410-12051 as the 920-966D starter. The trade-off is that the model list is narrower, so this one is not positioned for the 920 through 966D family. If your loader is a 980 or 980B with the 3306, this is the matching unit.
Final choice by use case
Pick the 920-966D starter if you own a 920, 930, 936, 950B, 966C, or 966D from 1969 to 1984. Pick the 980/980B starter if you own a 980 or 980B from 1966 to 1983 with the Caterpillar 3306 engine. Your loader model decides the right starter in this comparison.
