How many of you are using gear pumps instead of diaphragm types and what filter element (micron) sizes are you using?

Generally those pumps can handle the gear oil temps we have with no issues. The extra quart of oil will not cause any leaks unless the input shaft seal is worn a lot and/or you park on a very steep downhill grade all the time. I never experienced any leaks or weeps during the years the system was installed. I would not worry about getting the temp too low unless you are racing in snow as the exhaust will keep everything back there toasty warm!
Patrick does sell a couple of handy transmission related items, one is an aluminum adapter that replaces the speedo drive and has a VDO sender matched to a temp guage. Another is an hi temp reversing wheel for the clutch cable which will never get soft or wear out. I used both items and they were very handy. I did have one of the factory wheels get smoochy in a race in Mexico and the cable came off and scared the hell out me as I thought I'd broke a trans or clutch! |

... or you park on a very steep downhill grade all the time. ... the exhaust will keep everything back there toasty warm! ... speedo drive and has a VDO sender matched to a temp guage. Funny you should mention the grade. My driveway is extremely steep. But the input seal has never given me a problem. That exhaust is always an issue. It's so close to my oil return hose that I'm sure I get a significant engine-oil heat jump. I put in an additional cooler (sandwich adapter) at the oil filter console behind number six. I turned an aluminum, double o-ring plug to block off the speedo drive hole and considered putting a temp sender in it. But I though it might not give me the temp I really wanted which was in the R&P or main gear chambers. You think it would be close enough? It's an elegant place for one and easy to drill and tap. |
