oil change Raid 4by with oil cooler. Changed oil for first time since buying bike.

TTRfan · Super Guru

Was the oil covering the whole of the sight glass before you removed it? My guess is that the previous owner over-filled it. Trust the manual. Make sure that after you have re-filled and run the engine that the oil is about 3/4 up on the sight glass.

I use Silkolene Super 4 10/40 semi-synthetic.

Air-cooled engines tend to have bigger clearances than water-cooled and a beefier oil helps fill the gaps wink

Sorry - I have looked through my parts catalogues and can't find the oil cooler listed. Hopefully someone else will be able to help you.

Would this fit and be alright to use on the ttr? not a bad price and would help.

this looks better http://www.funbikes.co.uk/Pit_Bike_Oil_Cooler_Performance_Upgrade(3160).aspx?gclid=CMqzs5T43bICFSfMtAodYzAAnA

-- Edited by sammyttr on Sunday 30th of September 2012 07:35:36 PM is it the 2 bolts in a row on the right they bolt on to, are they banjo bolts already there or would they need to be purchased and what size banjo ring would it need to be

-- Edited by sammyttr on Sunday 30th of September 2012 07:37:56 PM

sammyttr · Senior Member

this looks a better one my mate suggested as long as the banjo bolts are M8 it be a straight fit and 12mm

Raid with oil cooler, how much oil?

Cubber · Super Guru

I don't know, but.......... it'll be less than a pint, won't it? confuse

If 'twere mine I'd fill to the line on the sight glass and warm the engine up.

When it's warm the cooler should be as full as it will be and I'd top the level up to the line on the sight glass again. aww

Job done?

Taken from the Faqs.....

Can I fit an oil cooler?
If you live near Sydney in Australia you can get a complete kit from Yamaha Australia via your bike shop. Part number YAM-4GY-WO793-00 - cost $285 Australian at the beginning of 2002. Adam lives in Windsor NSW and got his from Wombat Motorcycles (45878153). Speak to Gary or Angie or Jay (the new owner) and they can order you one. Costs about $250. The kit comes with everything you need and takes about an hour to install. The hardest part is removing the clutch cover to replace an existing blanking bolt with a 10mm longer one to blank off the internal oilway and divert the oil around radiator part of the cooler - see photograph. The kit even comes with a new clutch cover gasket. You get about 1/2 litre more oil capacity and prolongs the life of the oil dramatically. Anybody with basic tools and mechanical knowledge can do it. Adam says "Feel free to email me at adkaz71@hotmail.com with any questions". For UK owners, the part is available from Yamaha Holland via your local Yamaha Dealer - retail price is £226.63 GBP. Some good advice is to fit a bash plate to protect the oil lines which run from the crankcase to the radiator.

.................................................................

So it's roughly 1.5 litres

Thanks guys....1.5 litres sounds good to me, ill give it a go. Thanks again.

Well found Jarrah! Good to see the FAQ is still useful wink

Sadly the part number doesn't show on Fowlers (UK) parts search cry

Yeah wink .......I nearly wrote roughly 1.7 then relized about the different oil capacity of the older models smile

Not sure if it's nessasary to fit one????? any thoughts???

Depends on your riding conditions I guess. If you are going to be constantly thrashing the engine, or ride in Sahara-type conditions, then the extra cooling and oil capacity will certainly help extend the oil and engine life.

I have got an original Yam cooler ready to fit to my 325 when I get around to fitting the new barrel.

I recall another forum member researching an after-market cooler to fit the TTR - did he succeed?

Brian

barra8 · Guru

Thanks Brian that confirms my thoery. I may try to find one myself....not sure about aftermarket now wink

BM Steve · Guru

I'd thought about buying one for a while but figued if I'm really hot then so is the motor so just slow down a bit or have a break

You can also buy a hell of a lot of extra oil for $285.00

Also it's just one more thing that can be damaged, after all the reason I bought a TTR instead of anything else was no water cooling system/Radiators etc... smile

I have had a quick but disappointing reply from Fowlers as follows:

“Hi, the part number you supplied only works if you replace the 'O' with a '0', but is of little help as Yamaha show no stock in either Europe or Japan, so it is effectively discontinued. Kind regards, Spares Team”

So the only way forward for an owner wanting to fit an oil cooler would be to buy a s/h unit or to adapt one from another bike.

Wow - that's a rarity - haven't seen one put up for sale for ages.

I recommend that anyone interested moves very quickly!

Have you tried the rope and wire place in Bakers Yard Marsh Barton they do a whole range of ss nuts and bolts of nearly every size...... Ive used them many times.

Thanks Mike - it's not for me but my good mate Adrian - see his earlier post - but it may be that Bakers Yard can help so thanks for the tip. It is the "blanking plug" for the oil cooler he has just bought off Paul wink

I have a bad feeling about this as I can't find any bolts of this size and pitch on the interweb other than banjo bolts hence my plea for help. I tried a big supplier on the phone and his reaction was "Good luck with that mate!" which wasn't helpful. Can't find a Yamaha part number for it either cry

Hi all

Meantime, in the background, I have just bought an oil cooler from allweatherbiker (thanks very much, beautifully packed & arrived asap)

Does anyone have the long bolt I'll need to divert the oil flow to the radiator?

(I've read the tread; did Paul 13 have the bolt? have you got another one? Allweatherbiker have you got the bolt I would need? Have I missed it in your packaging? Noeyedear did you find a bolt from another source?)

Cheers

Mark

If allweatherbiker runs the TTR with the oil cooler removed and the blanking bolt still fitted it will seize the engine (been there and got the T shirt disbelief ) so best replace it with the shorter bolt to allow the oil to circulate asap!

Brian

Allweatherbiker · Member

Thanks for the heads up.....will take the cover off today and se what size bolt is in there......i may of sold the long bolt with spare engine as i swapped clutch cover when i put the new engine in but can't be sure so will have to check now arrrrrr bloodly pain in the arse.....lucky for me i not started the bike since i removed the cooler. So if it is 25 26mm long i will have to swap it. DAm IT

Allweatherbiker · Member

LOL noeyedear I don't have a long bolt either....so I have been running a oil cooler with no oil in it, yet it dripped out oil when removed...well happy days for me as the engine won't seize :).....Maybe if ya need a longer bolt, you would have to get a engineering firm to make one or weld a bit extra on the short bolt.

spit · Veteran Member

Glad to hear Allweatherbiker's engine won't seize.

Not so good for me that neither he nor Noeyedear have the crucial long bolt.

From what I've understood on this thread the bolt is not commercially available, bugger.

Does anyone have the bolt I need or know where I can get a bolt from please?

Cheers, Mark

Oil cooler ?

texasT · Senior Member

PERFECTLY Valid question sir.

I don't think it matters if a oil cooler is installed or not when it comes to the oil level in the site glass. Fill between upper and lower line. NOT TOO Much.

Someone may come later and correct me, but it don't matter if it has a cooler or not oil levels in motor stay the same. You Might have to use a tad more oil - OR Not. -When I put a Oil cooler on my Harley, I figured it would take a bit more oil since there was some extra oil line added to and from the actual cooler and then to consider the volume of oil in the cooler, but as it turns out it was not enough to worry about.

TTRfan · Super Guru

I got an oil cooler on my 325.

When I change the oil, I fill up to the top line, run the engine to make sure the cooler and oil lines are full, let it sit for a while and then top back up to the top mark.

Brian

66T · Veteran Member

When I had an oil cooler fitted to mine, the instructions said to add 200ml extra oil. Total fill after drain with filter being 1.3L. I have run 1.3L without the cooler for years with no ill effect. Oil level is better over than under as TTR crankcase temps in hot weather are very, very high. Bike has now got > 70,000 km without even new rings yet.

1.3 liters is the standard oil change with filter for a blue model. The total amount is 1.4L. About 1.5 would be good with an oil cooler.

Jarrah

66T · Veteran Member

According to my Yamaha workshop manual 1.1L periodic change, 1.2L with filter, 1.45L in total. Without oil cooler, of course.

It does say 1100cc on crankcase but i find this only just puts the level on the side glass so 1300cc plus id good for my blue bike

TTRfan · Super Guru

See here

As Yamaha state in the handbook that the volume of oil required for an oil-only change on a 7-plate clutch model (most blue TTRs) is 1100cc, I reckon that's why it's stamped on the clutch cover wink

It's a 100cc less for 6-plate clutch engine as the cover is shallower i.e. 1,000cc for an oil change only.

The standard engine displacement is 249cc.

What is the extra volume that takes it up to 1.45l (1,450cc) though confuse

Lol
The cubic centimeters (or cubic capacity) of an engine is the volume of the cylinder i.e. how much fuel/air it takes to fill the cylinder. See more detailed info here- http://www.scooterhelp.com/tuning/defs.ccs.html

It's nothing to do with the bore/stroke/displacement confuse biggrin confuse confuse

The casting of 1100cm3 on the side of the crankcase is an indication of the oil capacity

If it was an indication of the engine capacity then it should read 250 cm3 - the clue is in the bike's name - TTR250

The instruction manual confirms the oil capacity (without cooler)

confuse That's not how the thread reads, Jarrah.

You responded to chrisstdt, incorrectly.

The volume (capacity) of the engine's swept volume was never in doubt. Only the volume of oil in the engine was being queried. wink
