Countershaft Compatibility

[hodakahunter]

Hello Hodakans!

Looking to replace the countershaft on my 92 Ace (gear and shaft pics attached). Wondering what the compatibility is between 92,B,B+ and 93 since they have different part numbers. Took advantage of Terry's weekend sale and got a transmission rebuild kit for 50% off, but he's out of countershafts.

Thanks in advance!

Looks like a lack of lube.

Most of the early 5 speed transmissions used the exact same countershaft (part# 924601). The only one I could see that was different was the very early Ace 100's, which used part # 914601R. The biggest difference that I could tell between them was the early one (914601R), used a snap ring to hold the countershaft sprocket on, while the later one (924601) used a nut to hold the countershaft sprocket on. The later one (part# 924601) was used on the Ace 100 B's, the chrome tank Super Rats, the chrome tank Wombats and Combat Wombat, the Orange tank Super Combat and Super Rat and the chrome tank Dirt Squirt. So, if yours has a threaded end, then it uses the 924601 shaft. I'm not positive, but I believe that the later shaft will work in the early engines.

#914601R was for the ace 90 racer. I am not aware that it was ever used on the ace 100, and I sold many of them. 924601 is listed as used on the ace 100 model 92. by my data -----------Clarence

Thanks guys!

Yes, this shaft is using the threaded end that requires a nut and lock washer to hold the sprocket. This is good news as it opens up my search for a countershaft!

Lack of oil seems to be the consensus. Seems a shame that it was allowed to happen but it did, and I caught it before putting it back together. Looking on the bright side of things.

I put a light rub of grease on the gears on the inside as I stack them on the shaft. Lubes it until the oil gets there, plus holds the gears in place a bit better as well when assembling. Victor

That has to be 2nd gear. REAL common problem spot! Replace the Main Shaft Bushing and check out the Kick gear. The Main Shaft, Second Gear and the Kick Gear get out of alignment when the Bushing is shot. When you look at the Counter Shafts on EBAY nearly every one is scarred where Second Gear rides.I`ve wiped out a few Counter Shafts through the years where Second Gear rides and the bushing was worn out real bad. Did you talk to Terry at HPI? Paul Stannard had some so Terry should have some now. That sale was GREAT! A Brand New Main Shaft and 5 New gears for $50.00. He must have Tons of Model 92 Gears to sell them that cheap! Call Terry! He probably just has`nt updated his site yet. Joe.

Very common especially if ridden hard, needs the very best of lube Joe is right on!. ------Clarence

Joe,

No haven't called just email to give him time to respond, but I'll give him a ring today. From the photos I've seen, he must be SWAMPED with parts.

Yes, the kit was a great deal! (should have ordered 2!)

I've installed Terry's rebuild kit which included bearings, seals, and bushings. Would this be enough to re-align everything? To be honest the bushing that was in there was in great shape. Perhaps it had been serviced and the original gear and countershaft were reinstalled. Who knows.

Yes, used countershafts that I've seen on Ebay are more worn than mine, so have concluded it needs to be an NOS part. Is anyone aware of production for a more durable countershaft? Seems like these are becoming harder and harder to get and ARE a wear item.

Any suggestions on a gear oil that may reduce the probability of me causing this problem again?

I like the Klots synthetic 30w. Danny Cooke recommended it to me several years ago & ive been using it ever since! I buy it on EBay, 3 bottles at a time! Victor

Is this what you’re looking for? This was in a bundle of parts I bought.
Looks to be in very good condition.
It’s yours if will get you going again. I don’t want money, just maybe you can help me with something down the road.

[Joe Ormonde]

That one looks Great! Just polish it up and check it. A new gear on an old shaft even with a tiny scratch after polishing is just fine! It`s when you install a used gear on a New Shaft that can be a problem later on down the road. Back in the day Guys that Raced T T and Flat Track took out the Kick Gear and would push start the bike. They also used Castrol R40 as a Gear lube. Better stuff out there now. The one thing that the British Fighting Rommel in the North African Desert couldn`t figure out was why the German Tanks WOULD NOT FRY THEIR ENGINES and the the British Tanks did. The German Tanks ran out of fuel and were abandoned. What oil was in the German Tanks? Castor Oil! BUT that same oil was used in the U Boats by mistake in the hydraulic systems and they went BLOOP to the bottom of the North Atlantic! History is Neat! Joe Ormonde.

Tether - How rough is the surface of that bushing end? The one I have is a mirror finish down there. Odd that that one would wear there since it's sitting in bronze. The offer is appreciated. I'll try and talk to Terry this afternoon and see what he says first.

Joe - I forgot to mention that I replaced the kick retainer to a newer heavy duty one with new rollers and shaft. I'm in this pretty deep!

Victor-I'll take a look at the Klotz, thanks!

[Tether]

I took a close look at it again and though it’s discolored a little I can’t see or feel any gouging or wear. I’m not even close to an expert about these things though. I have no idea why these parts were removed from whatever they Were in.

Dug in my box some more and found another one, this one looks even better. It has the “mirror” look as you mentioned.

[hodakahunter]

Bob,

That one is in near perfect condition! And has had the control rod and assembly removed which wouldn't be needed. If the offer still stands, I would take it. I'd prefer to give you something for it. Terry is charging near 60$ for NOS. I only have the one 92/Ace 100 so haven't collected a critical mass of parts yet to swap for.

Need anything for a YL1 or a CB350?

[Tether]

I don’t have those bikes.
On the vintage side I have:
3 Wombats model 94
2 Dirt Squirt 80s Model 82
1970 Yamaha DT1 250
1978 Kawasaki KL 250
1978 Honda XL 125
1974 Indian ME 100 (with a Hodaka 100 “E” motor)

I’ll send you an email and we can work out the details.
Bob
