Title: Cooling fins
Post by: Ceasar 222 on August 21, 2021, 04:18:38 PM
How much does the lister sr2 marine have to be stripped down
To get the cooling fins cleaned

All external covers to the point that you can either get an air line in there and blow it all clear or you can get to the fins to scratch them clean using a screw driver.

Looking like I will have to take the cylinder heads off
Injectors off rocker oil feed pipes
Is this to much for a novice I do have the workshop manual
And an abundance of tools also a torque wrench

Is it really that dirty? Do you have any pics of the problem?

@ Ceasar 222
I had an SR2 turning a generator that was very dirty when first acquired. Removing the tin from the cylinders was sufficient access to get them relatively clean by stuffing a rag between the fins. If you want really clean, a blast with a pressure washer (all vulnerable bits protected) or for spotlessly cleaned, a disassemble and hot tank immersion would work.
BTW, I also had a marine SR2 in a boat about 50 years ago.......what a great engine. Noisy, but absolutely reliable......and the exhaust heat could be directed into the cockpit for warm feet.
Cheers
Hugh

Good advise from Hugh and well done to you for posting the pics. For me I would be more than happy to just remove the tinware and either air or water blast it clean and as advised protect the sensitive parts like electrics.
