Do what you want - but the pump will work fine with cold starting at almost zero transfer-pump pressure as long as the static timing is set correctly.It was one of many issues that Deere suspected with starting problems with 40-series tractors. On a few it was true, with most it had nothing to do with the problem. You can buy brand new starters for around $150. Direct drive and gear reduction. Keep in mind that gear reduction starters will usually crank better in cold weather and can do it with a smaller electric motor - so the motor amp-draw is not always a good figure to use. Deere originally used 700 amp and 900 amp ratings on direct-drive starters. When they started getting rated in watts or kilowatts instead of amps, it kind of lost me. My 7.3 diesel in my Ford truck has a 3000 watt starter and works great. My 6.2 diesels have 2700 watt and 3500 watt GR starters - going by their ratings - and all work fine. Try DB Electrical - that's where I've been buying.
