whilst my 748 is in several hundred bits having every corroded 20yr old nut/bolt replaced the thought occurred to me I could instal an oil cooler when I put it all back together again. (If I can remember what goes where ). There are blanking plugs in the crankcase bottoms that would appear to be where the oil pipes would go it were a 748R or 916, so it should be simple to instal. I’d be grateful if any of you nice people out there could post some pics of your 916 (or 748R) oil cooler so I can see exactly how/where it’s connected please. TIA
Go for a 996 oil cooler mate, they use O rings to seal the pipes far better than the early types, plus your need new cam feed lines unless you go the race set up.
It just so happens my bike is in a million pieces! But the engine is away, so can’t reference on that. But the top fitting on the casing goes to the left hand fitting on the oil cooler, then the lower casing outlet goes on the right of the oil cooler. Don’t forget that there is also an oil line that goes from the oil cooler to a fitting on each of the heads
Yep, this one number 14 in the diagram. As cookster says, the feed lines too the heads are different also. It is a straight forward job once you have the bits. Steve
@RickyX it looks like that spring valve just sits between the oil filter & the sump? What operates it and what’s it for please? Also @cookster @TelRobinson rhs is for the heads up about the extra lines to the cams. I’ll take a look later and see if the sockets for those pre-exist on mine and are simply blanked off as it appears are the crankcase ones
The lines to the head are a straight replacement for the ones that are on there now, it just connects to the oil cooler itself. The spring plate that fits between the filter and engine just reroutes the oil flow through the oil cooler pipes when fitted. Steve
Do you really need an oil cooler? Unless the bike is for track use, i'm not sure the cost is worth the benefit.
Thanks, so they’re not ‘extra’ just longer/different. Thanks for the knowledge about the spring plate
My 748R is on the bench so will get you some line layout pics in ten days. There is a 748 RS on ebay that has some decent engine pics.
Probably not, but whilst I’m in there and she’s all in bits I have had the thought about fitting one. Can’t see I’d be using her on the track, there’s only one here in Ireland AFAIK and once she’s back together in mint/as new condition I’d be afraid of dropping her.
Just an 853cc conversion with superficial stuff thrown at it at and at an outrageous price but that’s Jemspeed for you. Andy
Presumably you have a union of some sort where the cooler pipes connect to the engine, if so will the original feed to the heads fit. Steve
