Everywhere you read about Triumph Bonneville's it is reported that adding an oil filter is a smashing good idea. Seeing how my oil in frame was powder coated and may contain sand residue I thought an oil filter is what I need. M.A.P. products sells a filter recommended by the masses which is concealed behind the engine and installation time is 30 minutes perfect So Friday I started the 30 minute install What the direction said Remove return oil line. Remove upper right engine bolt, and save thickest washer. Attach supplied oil lines to filter and connections on engine and tank. Secure filter by reinstalling clamp to engine bolt and reinstall engine bolt using only thickest washer. You're ready to go What the directions meant Remove return oil line (mine doesn't have one yet so step 1 is easy) Removing engine bolt revealed only one thin washer and a short bolt that is too short to reinstall with the clamp so a trip to the hardware store to buy new bolt, only problem was I need 1/4" more but not available so I got 1/2" more and some washers (we won't add that time into the 30 minutes). Next attach supplied oil lines to filter and engine and tank, well I can't find the supplied oil line because I bought the filter months ago. But never fear I've got some of my own on hand. Next Secure filter This got a little tricky because it doesn't fit. After screwing around with it for 90 minutes in different configurations the only way to fit it in was with the oil line is pinched behind filter. So we call the supplier but the tech guy is racing this week and won't be back till a week from Monday. So the logical thing to do is crack a beer and head back to the basement and do some logical reassessment. Now if you spend 2 hours removing the carburetors, side covers, air cleaner box, move some wiring, get a hacksaw and remove some of the oil pipe welded to the frame, then clean up the cut oil pipe. You can actually get the oil filter to fit like the instructions say. Now the problem is all that f'n around with the fit out has scratched up the filters lousy paint job pretty good, so all you got to do is sand it, mask it, and paint it, wait 24 hours for the paint to harden and then do the 30 minute install as the directions said which is where I'm at on Monday morning Perfect Note: I have a 1979 T140E and I suspect the oil pipe is longer and the airbox is obstructive on this model and once the filter is installed it is everything that is advertised and I would highly recommend this product.
Bob - You make my point exactly. As I've said in the past, you have to take all these catalog claims with a grain of salt.
However, you are exactly correct on one idea: Adding an oil filter IS "a smashing good idea". You'll never regret that move.
I'm not sure what oil line you ended up using, but 3/8" ID fuel line from any auto parts store is all that's required. You don't need aircraft-grade or stainless steel braided anything; there is zero (0) pressure on both oil lines.
The main concern for the oil lines is stones and grit thrown by the rear wheel gnawing a hole in the line. You can easy obtain and install the black nylon electrical harness spiral wrap and place this over the line after installation. It's black, abrasion proof, won't rust AND it will actually keep the hose from kinking on tight bends! Great stuff.
The MAP filter I bought for my pre oil in frame was a pain to fit too! By the time I had finished, it looked all scratched and knackered just like yours! I think every part of my bike must be subtly bent or out of line as no after market parts ever fit easily. However, the oil filter is about the only useful aftermarket part and really will help to keep your engine in trim. Dave

Actually, the logical thing to do would have been to crack a beer (or three) before you attempted the installation. Then you wouldn't care if it didn't fit. Works for me all the time . And I have one of those '79 T140Es, too. You've given me something to look forward to . Congrats on your perseverance .

I installed a MAP filter on my 1978 t140e. It appears that the larger air box on the t140e's makes the fit a little more difficult. You have to finesse the housing into place and may have to take it on and off a few times to get the hose lengths right. It probably took me about an hour. The instructions also say you can change the filter just by loosing the clamp and rotating the housing. I haven't tried it yet but it looks like you might have to take the housing completely loose. All in all, it looks like a well make product and I think it was worth the trouble.
I also was planning on procuring the MAP filter kit for my 1980 T140E. Previous to this thread, all I had read was how great they are and how they practically install themselves on your machine. And now this tale. I guess all the previous reports were about pre -"E" T140s?
Thanks for the report! I will now go into this task asssuming it will not be one-two-three ride.

I've probably installed a dozen of the MAP units for my own and other people's bikes. IMO, the hardest thing about mounting them is: A. figuring out exactly where you want to mount it B. getting the lines to fit and aligned just right.
I have never done one that was a ½ hour installation. Once the details above are worked out, it takes maybe 20 minutes to actually install and connect. I find the 2 little details listed above can take some time though. But usually a little time and a few adult beverages do wonders for working out the details .

I'm surprised no one has mentioned a Norton filter base mounted under the swing arm. The filter disappears once it is mounted but I routinely unscrew it and show how easy the filter is to change. All that is needed is a 3" muffler clamp around the center frame tube and two 5/16" fine thread Allen head screws to mount the base to the clamp. The hard part is getting the 5/16" Triumph oil return lines on the 3/8" base fittings.
I like this much better than the MAP filter.

No, not really. I got the idea from the Norton 850. They use a flat-wound steel spring to do the same job, but after the sand and grit knocks the paint off, the rust looks even worse!
The harness wrap, being no-metallic, won't ever rust and won't rub the paint off your frame or other surrounding parts.
I wish it weren't needed either, but my filter is also below the swing arm and the lines do not have the protection of the rear fender. I simply figured $2 for some black harness wrap was the cheapest insurance I was ever going to get.

MAP shows a Norton Adapter and filters on p.68 in their catalog under the pictures and description of the aforementioned recalcitrant MAP Oil Filter Kit. I'm assuming this is the Norton filter base being discussed here? Thanks

I'll speak up for the MAP filter as well. I followed the directions and got it installed on my T140V in about a half an hour. I initially had a leak becasue they supply 3/8 oil lines to fit the 3/8 nipples on the filter. The fit was a little loose on the 5/16 triumph nipple which has no flare. A dab of non-setting sealant and re-tightening the hose clamps brought it oil-tight.
