Engine Removal - SR4

[YellowPeril1]

Had a great day at Blyton in my SR4 last Sunday. It was only the second time out but I’m now feeling really good in the car and am picking the pace up nicely.

Unfortunately an oil leak appeared which I’ve now traced to a crack in the engine casing underneath where the oil pump bolts on. I’m guessing this happened when the chain let go last time out. Fortunately I know a local chap who does specialist welding for some of the super bike race teams and fingers crossed he’ll be able to sort this for me - however, I’ve got to pull the engine out first.

Does anyone have any instructions or pointers for removing a Hayabusa from an SR4 (or SR1)?

Thanks.

I find getting the engine builder to take the engine out, while watching and drinking tea is the best option.....

I'm not fan of engine removals myself but having removed my previous zzr1100 clubsport engine a few times and now my PR6 Hayabusa I was glad I did it myself as it's remarkably straight forward.

Providing you've got an engine crane it's just a case of draining the oil and coolant, disconnecting pipework/wiring/exhaust/chain, support the engine with the crane then remove the engine mounts and lift it out.

It never fails to amaze me how well they come out, people/teams that do it regularly must be able to do it in no time at all.

One thing I'd say is remember to get the car on stands so there is clearance for the engine crane legs to move freely - if you have a hoist then you don't have to worry about that.

All this is assuming the SR4 is a similar procedure to the clubby & PR6 - sure it will be though.

Cheers,

Dunc.

I am far from being a mechanic, but I have removed the engine a couple of times myself from my PR6. I did it in 2 hours, being very careful and diligent, so I am sure it can be done in less . It is a very simple exercise, once you did it the first time. Take it step by step and enjoy the day .

This jogs a memory or two for me, when I raced my sr4 I had an engine let go at Pembury and our next race was an hour away so the guys at RSR ( Woody et al) came to help and they took my engine out and fitted an exchange engine from radical works team and as they called the grid I was on my out while they were fitting the bodywork back on !!! Those were the days and I really miss that team spirit.

Still happens in the Radical paddock, There have been a few occasions when the Radical guys helps another team and jump on someones car to swap the engine quick.
