Oil cooler bracket sheared off
« on: April 26, 2015, 07:21:25 pm »
So fooling around doing some maintenance, checking frame bolts and generally poking around, I discovered that the bottom bracket holding the oil cooler to the frame has broken off.

Removed everything from the bike and sat around for a while contemplating what to do. It us quite thin and I was not sure if it could be welded so I wipped out thw Q-bond and set to work.

No idea of whether it will hold, but so far so good and I was able to re-mount it.

Any other, maybe better, ways to fix this?

Is there any issue around bleeding the system? Dont think so, as very little oil came out of the oil cooler which suggests that it is only pressurised and filled when the oil pump is working.

The oil cooler bracket of my '99 DR 650 sheared off at the exact same position.

This was caused by repetative hard landings, while riding the Kruger fence line.

With every landing, due to the mounting angle of the cooler, it is forced forward, resulting in the bottom bracket breaking off.

I doubt if the Q-Bond repair will last.

Have it welded at your local engineering shop, or specialist welder.

Remove the rubber, by first removing the metal bush.

They could only weld it on one side.

When ever I ride rough terrain, I cable tie the oil cooler grill, through the thicker frame, to the protection bar with 2 cable ties.

Rinse the cooler with petrol, with both feed and return connections removed.

These connections have an o-ring inside.

Let the cooler dry, or blow with compressed air.

Crank the engine a few rotations with the plug wires removed.

Check oil level.

Start engine.

BTW

I do have a spare oil cooler, but prefer to keep it as spare.

Sure the weld will be cheap.

My repair has lasted the past 2 years.

I have made a modification to support the cooler on the guard side.

Needs a few finishing touches though!

Thanks guys,

Also realised that Q-bond will not hold when in used it to fix my chain guard and it broke witnin a few km's.

So I phoned a friend - my engineer Groenie ;D who knows who can weld it properly. I asked him to "superweld" it, strengthen it, to do watever can be done to fix it properly and permanently. This is not something I want to worry about breaking again.

Update - I am fortunate to have some good friends who knows some other good people ;D

The result is a very good TIG welded repair and I am sorted again. Thanks Groenie and Jacque :thumleft:

P.S. when I was busy re-fitting the unit I noticed that I had lost one of the small O-rings. Being Sunday, I thought I was screwed, but took a chance and popped into Midas. Managed to find a near identical O-ring to fit. Works perfectly and I could re-assemble and ride my bike yesterday ;D
