[xk] Rear Shock Lubrication

XK
1

I am about to check the level of the fluid in the rear lever
shocks. The manual says to use Girling Piston Type Thin Oil.
Does anyone know what the modern equivalent is?–

I suspect maybe SAE140 gear oil.

John,
Penrite makes a steering box lubricant that I have found to be particularly well-suited.

Suggest you visit a motorcycle shop, they should have ‘‘Front
fork oil SAE10’’ or similar. Works fine in the XK120 rear
shocks.–

When I bought my car in 1970 I purchased a can of “Hydraulic Jack and Lever
Shock Oil”, so any lightweight hydraulic oil should work.

Thanks everyone.

I ended up getting 90-140 wt gear oil for the steering box; and
front fork 10 wt motorcycle hydraulic fluid for the shocks. SK99,
thanks for the source, when to the only motorcycle dealer in the
county and picked up a couple of quarts.–

I didn’t think I had the apparatus to fill the lever shock with ease, but noticed a quart of gear lube had a small nipple that would fit into the filler hole. I tried the nipple on a short, very pliable water bottle and it tightened up fine. Used that with very little spillage.

Moss Motors sells shock oil for Girling and Armstrong lever shocks, part 220-304. I also used the nipple spout cap from a bottle of gear lube and a length of hose to squirt it in.

although there are other fluids of all kinds…I use the correct ones that are still available…so…as mentioned, shown by others, Penrite makes the 140 steering box lube, and there is shock fluid made for Girling lever arm shocks, and there is SU carb dashpot oil. What there is NOT readily available in lubrication, .unless careful in shopping is engine oil with zddp, in proper weight (not 5W-whatever) and without too much viscosity improver, 30 weight conventional oil for the gearbox, and also fuel without ethanol. Any 75-90 gear oil is ok for the differential…note tho that brands, types do not mix well…and a drain, flush , refill, should be done if you don’t know what was in there prior.
